Key Highlights:

• A survey of 2,000 regular exercisers and commentary from sport and exercise specialist Dr Amos Ogunkoya identify three frequent pre-workout errors: training under‑fuelled, relying on quick sugar fixes, and mistiming nutrition.
• Coffee, biscuits, chocolate and energy drinks are commonly used for a rapid boost but can cause energy crashes or impair performance; proper timing and balanced carbohydrates plus hydration deliver more reliable results.
• Practical, evidence-aligned guidance for pre- and post-workout fueling — including time-based snack plans and sample choices (plant-based and omnivorous) — helps athletes and recreational exercisers maintain energy, reduce fatigue and improve recovery.

Introduction

People go to the gym for many reasons: strength, stamina, weight control, mental clarity. What they put in their body before stepping onto a treadmill or into a weight room directly affects the quality of that session and the adaptations that follow. New research commissioned by Flora and discussed by Dr Amos Ogunkoya — a sport and exercise specialist — reveals persistent misconceptions about pre-exercise nourishment. Many exercisers reach for coffee, chocolate, biscuits or energy drinks in search of a quick lift. Others skip eating entirely.

Those choices can work against performance. The right fuel, at the right time, supports power output, delays fatigue and speeds recovery; the wrong fuel — or none at all — increases the chance of energy crashes, weak sessions and stalled progress. This article examines the physiology behind those outcomes, breaks down the three most common mistakes highlighted by Dr Ogunkoya and the survey, and gives clear, practical fueling strategies for different goals, timeframes and dietary preferences.

Why pre-workout nutrition controls how well you perform

Exercise draws on multiple energy systems in the body, and the substrate available at the start of a session determines which systems dominate. For moderate-to-high intensity work — sprinting, interval training, heavy lifting, tempo runs — carbohydrate availability is critical. Muscle glycogen and circulating blood glucose provide quick energy for anaerobic and fast aerobic efforts. For low-intensity, longer-duration activities, fatty acids contribute more but carbohydrate still matters once intensity rises.

Key physiological points:

• Glycogen stores in muscle and liver supply much of the substrate for high-intensity work. These stores are finite and deplete with prolonged or intense training.
• Blood glucose supports central nervous system function and immediate muscular demand. A rapid fall in blood glucose can reduce power and cause dizziness, shakiness or "brain fog."
• Insulin and gastric emptying affect how quickly ingested carbohydrates become available. Simple sugars raise blood glucose fast but often trigger an insulin surge that can lead to a subsequent energy dip.
• Caffeine acts as an adenosine receptor antagonist, reducing perceived effort and improving endurance and alertness when timed and dosed correctly.
• Hydration and electrolyte balance determine cardiovascular efficiency and thermoregulation; mild dehydration reduces performance and increases perceived exertion.

Practically, this means two things. First, pre-exercise intake should match the session’s intensity and duration. Second, timing matters: nutrients need time to become available and to avoid gastrointestinal discomfort. Misjudging either leads to the three pitfalls highlighted by Dr Ogunkoya.

The three common mistakes: what people do and why it backfires

Dr Ogunkoya identified three recurring problems in clinic and sport: training under‑fuelled, relying on quick sugar fixes, and mistiming nutrition. The survey of 2,000 adults who exercise at least twice weekly illustrates how widespread these behaviours are.

1. Training under-fuelled

• What people do: About 27% of respondents regularly train without eating beforehand. Some choose fasted sessions deliberately; others skip food because of time constraints, lack of appetite or to "burn fat."
• Why it backfires: For higher-intensity sessions, insufficient fuel limits power output, reduces the ability to sustain intervals or heavy sets, and makes perceived effort higher. Being under-fuelled increases the risk of early fatigue and reduces training quality, which over weeks and months slows progress toward strength, speed or endurance goals.
• When it may work: Low-intensity, steady-state cardio (e.g., light recovery runs or gentle cycling) can be performed fasted with minimal downside. Fasted training may assist some metabolic adaptations but is not optimal for quality sessions.

2. Relying on quick sugar fixes

• What people do: Coffee, chocolate, biscuits, sugary drinks and energy drinks are commonly used pre-workout. The survey showed young adults (18–29) are nearly three times more likely to choose sugary drinks compared to the average respondent (13% vs 5%).
• Why it backfires: Simple sugars produce a rapid spike in blood glucose, followed by an insulin response that can provoke an energy dip as glucose is cleared from circulation. That transient boost may feel helpful at first, but it can be followed by fatigue, reduced mental sharpness and weaker training outputs. Energy drinks also carry high caffeine and sugar loads that can increase heart rate, cause jitteriness, and dehydrate if used improperly.
• Better approach: Prioritise low-to-moderate glycaemic index carbohydrates and pair them with small amounts of protein or fat when time permits. These options sustain blood glucose, provide slower-release energy and reduce the risk of crashes.

3. Mistiming nutrition

• What people do: Consuming caffeine or a sugary snack immediately before starting exercise, or eating a large meal too close to a workout, are common errors. The study participants showed a variety of snacks consumed immediately pre-exercise, including items that need digestion time.
• Why it backfires: Nutrient timing affects availability and comfort. Caffeine needs roughly 40–60 minutes to peak; taking it a minute before a session reduces its ergogenic benefit. Heavy meals eaten within 60–90 minutes can cause gastrointestinal discomfort, cramping or nausea as blood flow is directed to working muscles rather than digestion. Conversely, not allowing enough time for carbohydrate intake before a long or intense session may leave you under‑fuelled.
• Solution: Match what you eat to how long before exercise you have, and choose the composition accordingly.

These three mistakes overlap. For example, someone who trains under‑fuelled may then reach for sugary snacks immediately before a session to compensate — combining two pitfalls and magnifying the downfalls.

Coffee, caffeine and timing: use the stimulant strategically

Caffeine is one of the most reliable performance enhancers when used correctly. It improves alertness, reduces the perception of effort, and can boost high-intensity and endurance efforts.

Key practical points:

• Timing: Take caffeine about 40–60 minutes before exercise. This is when blood levels peak and the ergogenic effects are most pronounced.
• Dose: A common effective range is 3–6 mg per kg of body weight for performance benefits. For a 70 kg person, 200–400 mg is in that window. Lower doses (e.g., 1–2 mg/kg) may still help with focus and reduce side effects for caffeine-sensitive individuals.
• Forms: Coffee, caffeine pills, caffeinated gum and sports gels all work if timed correctly. Coffee’s caffeine content varies by brew; a typical 240 ml cup contains ~80–100 mg.
• Risks: Too much caffeine causes jitteriness, elevated heart rate, GI upset and sleep disruption if consumed late in the day. Energy drinks often pair high caffeine with large sugar doses, increasing the risk of a late energy crash and dehydration.
• Practical example: A pre-workout espresso taken immediately before a five-minute high-intensity session may not be optimal. Having that espresso 45 minutes before a one-hour run will deliver peak benefit.

Dr Ogunkoya underscored this point: caffeine can improve performance, but timing matters.

The sugar trap: why sweets and energy drinks are unreliable pre-workout choices

Survey data show sweets, biscuits and energy drinks feature among common pre-exercise choices. They are tempting: inexpensive, portable and fast-acting. But physiologically they are unreliable.

Mechanisms that create problems:

• Rapid blood glucose fluctuation: Simple sugars produce a sharp increase in glucose, followed by insulin-mediated clearance. For many people, this is followed by a "dip" in energy that undermines sustained performance.
• Gastric distress: High-sugar, high-fat snacks (e.g., chocolate, biscuits) can slow gastric emptying and cause stomach discomfort during running or HIIT.
• Hydration interaction: High doses of sugar or caffeine without adequate water increase the risk of dehydration and impede cooling mechanisms.
• Psychological crash: After an initial boost, mood and focus can deteriorate, reducing concentration during technical lifts or steady pacing.

Alternatives that provide steady energy:

• Low-to-moderate glycaemic carbohydrates: oats, wholegrain toast, rice cakes, bananas, flapjacks made with oats and honey.
• Small fat/protein additions: a smear of peanut butter, a small yoghurt, or a handful of nuts can slow glucose absorption and maintain energy.
• Liquid options: smoothies or diluted fruit smoothies that avoid excessive fibre and fat when consumed close to exercise.

Real-world example: A recreational runner who eats a chocolate bar 10 minutes before a tempo run may feel strong for the first 10 minutes but notice a sudden slump mid-run. A runner who eats a banana 30–60 minutes before the same session will get a slower, more sustained glucose release and is less likely to hit a mid-run energy low.

Practical fueling windows: what to eat and when

Fuel choices should be driven by how long before exercise you can eat and the session’s intensity. The following recommendations are evidence‑aligned and practical.

3–4 hours before exercise (full meal window)

• Goal: Provide ample carbohydrate to top up glycogen stores, include quality protein, and keep fat moderate to avoid slow digestion.
• Options:
  • Bowl of porridge with banana and a spoonful of nut butter.
  • Chicken, rice and roasted vegetables.
  • Plant-based bowl: lentils or chickpeas with rice and roasted sweet potato.
  • Pasta with lean protein and tomato-based sauce.
• Rationale: A full meal allows time for digestion, supports moderate-to-high-intensity training, and aids recovery if protein is included.

1–2 hours before exercise (light meal or substantial snack)

• Goal: Top up circulating glucose and provide easy-to-digest carbohydrate with some protein if appetite allows.
• Options:
  • Toast with peanut butter and sliced banana.
  • Greek yoghurt with berries and a drizzle of honey.
  • Flapjack (oat-based) with a small yoghurt.
  • Rice cake with thin spread of nut butter and jam.
• Rationale: These provide fast-access carbohydrates without heavy fats that delay gastric emptying.

30–60 minutes before exercise (small, rapidly digestible snack)

• Goal: Provide quick carbohydrate and a little fluid; avoid high-fat or high-fibre foods.
• Options:
  • Banana or peeled orange.
  • Small smoothie (lower-fibre, diluted).
  • A piece of white toast with honey.
  • Energy gel or sports drink for sessions longer than 60–90 minutes.
• Rationale: These give a modest blood glucose boost and are less likely to cause GI issues if digested quickly.

0–30 minutes before exercise (very small, easily digestible options)

• Goal: Top up energy without stressing the stomach. Primarily for those who cannot eat earlier.
• Options:
  • A few sips of diluted fruit juice or a sports drink.
  • A small rice cake.
  • Caffeinated gum or small coffee taken 45 minutes prior if timing allows.
• Rationale: Anything heavier could cause discomfort; a sports gel or drink is acceptable if it's formulated for quick absorption.

Specific session examples:

• Short, high-intensity strength training (30–60 minutes): small snack 30–60 minutes prior or 1–2 hours meal; caffeine 40–60 minutes prior can help strength and focus.
• Long run or endurance session (>90 minutes): carbohydrate intake before and during exercise matters; a full meal 3–4 hours before plus gels or sports drink during the run.
• Morning workouts with limited time: choose quick carbs like a banana or a small porridge; if doing fasted work, keep intensity lower or accept reduced power.

Categorising the top 25 pre-workout foods: useful, conditional, and poor choices

The survey listed the top 25 items people consume before exercise. Sorting them helps translate that list into practical choices.

Useful (good choices in most circumstances)

• Water — essential
• Piece of fruit/vegetable (banana, apple, carrot) — fast carbohydrate, minimal GI risk
• Porridge — steady-release carbohydrate
• Yogurt — carbohydrate + protein (choose low-fat if close to workout)
• Toast — easily digestible carbohydrate
• Eggs — good protein for a meal taken >1.5–2 hours before
• Protein drink/shake — useful for strength sessions when protein is needed
• Fruit smoothie — good if low in fibre and consumed >30 minutes prior
• Hydration gel/electrolytes — useful during long sessions
• Plant-based meal — appropriate if timed early enough

Conditional (can be useful but require timing or portion control)

• Coffee — excellent when timed 40–60 minutes before; avoid excessive caffeine
• Protein bar — depends on composition; many are high in fibre or fat which can cause GI issues if eaten just before
• Rice cakes — useful quick carb
• Pre-workout supplement — stimulant-based products can help but vary widely; follow instructions and test in training
• Creatine — beneficial for strength and power training, but not an acute pre-workout energy source; consistent daily use is what matters

Poor choices (likely to cause problems before most sessions)

• Biscuits — high in fat/sugar; quick rise in glucose then crash
• Chocolate — similar issues; added fat slows digestion
• Energy drinks (e.g., Red Bull/Monster) — high sugar and caffeine; can spike then dip energy, and cause jitteriness
• Sweets — pure sugar, prone to crashes
• Pasta, rice or roast dinner — heavy, slow to digest if eaten too close to exercise
• Pizza, cold meat, cheese — high fat and protein-heavy; risk of GI upset if eaten within 2 hours of exercising

Mixed items from the survey such as sports drinks, cold meat, and whole roast dinners can be appropriate in the right context (e.g., sports drinks during long workouts, protein-rich meals post-exercise) but are generally not ideal immediately before intense training if digestion time is limited.

Hydration and electrolytes: simple rules that matter

Hydration is not glamorous but it underpins cardiovascular performance and thermoregulation. The survey placed water at the top of the list — rightly so.

Rules of thumb:

• Start workouts well-hydrated. Assess urine colour: pale yellow is a practical marker of adequate hydration.
• For sessions under 60 minutes at moderate intensity, plain water is typically sufficient.
• For prolonged (>60–90 minutes) or very hot sessions, include electrolyte-containing beverages or small amounts of sports drink to replace sodium lost in sweat and to support sustained carbohydrate provision.
• Avoid over-drinking immediately before exercise; large fluid volumes can slosh and cause discomfort.
• If you use caffeine, account for its mild diuretic effect by ensuring you hydrate beforehand.

Practical example: For a two-hour marathon training run, drink 400–600 ml in the two hours leading up to the start and carry a sports drink or gels during the run to combine carbohydrate with sodium replacement.

Pre-workout supplements and ergogenic aids: when they help, when they don't

Several items from the top-25 list are supplements rather than foods: creatine, pre-workout blends, hydration gels, and protein shakes. Each has a place but must be used with an understanding of purpose and timing.

Creatine

• What it does: Increases phosphocreatine stores in muscle, aiding short-term maximal efforts and supporting increases in strength and muscle mass with consistent use.
• Timing: Daily intake (3–5 g) is more important than immediate pre-workout ingestion. A loading phase can accelerate saturation, but long-term maintenance is what produces benefits.

Pre-workout blends

• Composition: Typically caffeine, beta-alanine, citrulline, and other stimulants or amino acids.
• Use: Can improve perceived effort and delay fatigue for high-intensity sessions. Start with half doses to assess tolerance due to stimulant load.
• Caution: Proprietary blends obscure exact quantities; stimulant sensitivity and blood pressure responses vary.

Hydration gels and sports gels

• Purpose: Rapid carbohydrate delivery during long or high-intensity sessions.
• Timing: Use during exercise, especially beyond 60–90 minutes, and pair with water to aid absorption and reduce GI distress.

Protein shakes

• Role: Support muscle repair and growth when consumed after resistance training. They can also be consumed before exercise if digestion time is available, but they are not primary energy sources.

Practical guidance: Test supplements in training, not on race day or for important sessions. Assess tolerance and any side effects before adopting them as routine.

Post-exercise refueling: what the survey shows and what works best

The Flora-commissioned research found most people (76%) feel confident they refuel adequately after exercise. The top three post-exercise choices were fruit (26%), protein-rich foods like eggs (19%), and whole foods (15%). These are reasonable patterns.

Evidence-based post-exercise strategy:

• Timing: Aim to consume carbohydrate and protein within the first 30–120 minutes after finishing, especially after intense or prolonged sessions. This window supports glycogen resynthesis and initiates muscle repair.
• Composition: A common recommendation is approximately 1.0–1.2 g/kg carbohydrate in the first 4 hours for rapid glycogen repletion after prolonged training, paired with 20–40 g of high-quality protein to stimulate muscle protein synthesis.
• Real-world options:
  • Smoothie with fruit, yoghurt and whey or plant protein.
  • Egg-based meal with wholegrain toast and fruit.
  • Porridge with added protein powder and berries.
  • Rice or pasta bowl with lean protein and vegetables (for longer recovery periods).
• Practical note: For most recreational sessions, a balanced meal within 2 hours containing carbohydrate and protein is sufficient. Very long endurance events require more immediate and systematic glycogen replacement.

Barriers to post-exercise refuelling reported in the survey included time constraints, lack of appetite or fatigue. Planning convenient, palatable options (e.g., a pre-made smoothie or a protein bar suited to your GI tolerance) helps overcome those barriers.

Adapting fueling by goal: fat loss, muscle gain, and endurance

Fueling strategies should align with training objectives.

Fat loss

• Approach: Maintain an overall calorie deficit but preserve training quality for strength maintenance. Avoid routine high-intensity sessions while severely under-fuelled. Small, low-calorie pre-workout snacks (e.g., black coffee plus a piece of fruit) can help maintain intensity without derailing calorie targets.
• Priorities: Preserve muscle mass with resistance training and sufficient daily protein; place most calorie deficit outside of training windows rather than by under-fuelling all workouts.

Muscle gain and strength

• Approach: Ensure adequate daily protein and a modest calorie surplus if hypertrophy is the goal. Eat a protein-containing meal 1–3 hours before strength sessions, and have 20–40 g of protein within 1–2 hours after training.
• Priorities: Pre-workout carbohydrate helps sustain heavy sets and volume; creatine supplementation supports maximal power outputs.

Endurance performance

• Approach: Prioritise carbohydrate availability for long or high‑intensity aerobic work. For events or sessions over 90 minutes, combine pre-exercise carbohydrate with intra-exercise gels or drinks.
• Priorities: Train the gut if planning to use in-race nutrition; practise taking gels/drinks during long runs to reduce GI issues.

The underlying principle is simple: align energy and macronutrient timing with the demands of the session and the longer-term goal.

Real-world examples: runners, gym-goers and weekend warriors

Runners preparing for the London Marathon provide a useful context. Flora’s food tour — distributing flapjacks and recipe ideas — aims to show how simple, portable carbohydrate sources can support training and race day. For a marathoner:

• Pre-race breakfast (3–4 hours pre-start): porridge with banana, honey and a small spoon of nut butter.
• 60–30 minutes pre-start: small sips of carbohydrate drink if needed.
• During race: carbohydrate gels and sports drinks, taken at regular intervals, combined with water to aid absorption.

A strength athlete training in the evening after work might:

• Eat a balanced lunch with carbs and protein.
• Have a small snack 60–90 minutes pre-session (toast with peanut butter).
• Use a post-workout shake within 30–60 minutes if dinner will be delayed.

A time-pressed gym-goer doing a 30-minute high-intensity session at 7 a.m. could:

• Have a small, quick snack (banana or rice cake) 20–30 minutes prior.
• Take a 1–2 cup coffee 40–60 minutes before for an added focus boost.

The common thread is planning: match the snack or meal to timing, session demands and personal tolerance.

How to avoid GI issues: testing and personalization

Gastrointestinal upset during exercise is common when pre-workout fuel is misaligned with activity. Preventative steps:

• Trial and error: Test foods and quantities in training, not on event day.
• Avoid high-fibre and high-fat foods within 1–2 hours of intense exercise.
• Keep portion sizes sensible; a "little and often" approach can work for long workouts.
• Hydration: Combine fluid with carbohydrate intelligently; too much straight fruit juice can cause cramping due to osmotic effects.
• If prone to reflux or nausea, decrease volume and choose simple carbohydrates or sports gels.

Personalization matters. What works for one athlete may cause issues for another. Use training sessions to learn individual tolerance and ideal timing.

Practical grocery list and simple recipes for pre-workout fueling

Stocking a few reliable items makes consistent fueling easier. Focus on portable, shelf-stable and quick-to-prepare options.

Staples:

• Bananas and other easily digested fruits.
• Oats and flapjacks (home-made or commercial options with minimal added sugar).
• Rice cakes and white or wholegrain toast.
• Plain yoghurt or Greek yoghurt.
• Nut butter in single-serve packets.
• Sports drinks or electrolyte tablets.
• Protein powder for shakes.
• Coffee or caffeinated gum.

Three quick recipes:

1. Banana‑Oat Flapjack (easy to make or buy): oats, mashed banana, small amount of honey and nut butter. Provides carbohydrate and a touch of fat for sustained energy.
2. Portable Smoothie: low-fibre fruit (banana, mango), milk or plant-based milk, scoop of protein powder, blended and consumed 45–60 minutes before exercise.
3. Rice Cake Snack: rice cake topped with thin smear of peanut butter and a drizzle of honey; fast-acting carbs with a hint of fat for satiety.

Flapjacks are an excellent example: they combine oats (slow-release carbohydrate) with a touch of sugar and fat to avoid sharp insulin spikes, making them suitable as a pre-run or pre-ride snack. Flora’s tour uses flapjacks for that reason.

Age and behaviour: younger adults favour sugary drinks — how to redirect choices

The survey highlighted that 18–29-year-olds are significantly more likely to consume sugary drinks before exercise. Younger exercisers often prioritise convenience and perceived immediate energy.

How to shift behaviour:

• Education: Demonstrate how slower-release carbs and proper hydration improve training quality.
• Swap strategies: Replace sugar-laden energy drinks with diluted fruit smoothies, sports drinks tailored for exercise, or a small banana plus water.
• Social cues: Group training leaders and coaches can model better choices and provide quick snacks at sessions.
• Accessibility: Make portable, affordable alternatives like flapjacks and rice cakes available at gyms and events.

Practical nudges work: making better options easy to access at the point of decision reduces reliance on quick sugar fixes.

Putting it into practice: a one-week pre-workout plan to test improvements

If you want to see the effect of better fueling on performance, try this simple plan for one week:

Day 1–2: Track current pre-workout habits — note what you eat, timing and perceived session quality. Day 3: Make one change — if you usually skip food, have a banana 30–45 minutes before training. If you reach for an energy drink, replace it with a small porridge and coffee 60 minutes prior. Day 4–6: Continue with adjusted choices and add a caffeine test (40–60 minutes pre-session only once) to evaluate alertness. Day 7: Reflect — compare perceived exertion, performance metrics (weights, pace), and energy crashes. Adjust quantities and timing based on feedback.

This short experiment demonstrates how modest tweaks can produce measurable differences in session quality and recovery.

Final notes on safety, personalization and testing

• Safety first: If you have underlying medical conditions (diabetes, cardiovascular disease, gastrointestinal disorders), seek medical advice before changing fueling or supplement routines.
• Personalization: Use the guidelines above as a starting point but adapt based on personal tolerance, training schedule and goals.
• Test in training: Never try a new combination of supplements or timing on a race or an important competition day. Use training to learn what works.
• Incremental change: Small, consistent adjustments to fueling and timing produce better long-term results than radical overnight changes.

A few small changes — choosing a flapjack or banana at the right time, timing a coffee 45 minutes ahead, or avoiding an energy drink right before a sprint session — can transform how you feel and how you perform.

FAQ

Q: Is it okay to train fasted? A: Fasted training can be acceptable for low-intensity sessions and may suit specific metabolic goals. For high-intensity intervals, speed work or heavy resistance training, performance typically improves with some carbohydrate intake beforehand. Decide based on the session’s demands and your goals, and test in training.

Q: How long before exercise should I drink coffee? A: Aim for 40–60 minutes before exercise so caffeine reaches peak blood concentration. Adjust dose for body weight and tolerance—typically 3–6 mg/kg is effective for performance.

Q: I only have 15 minutes before my workout. What should I eat? A: Keep it tiny and easily digestible: a small banana, a rice cake with a smear of jam, or a few sips of a sports drink. Avoid heavy, fatty or fibre-rich foods that could cause discomfort.

Q: Are energy drinks ever appropriate before exercise? A: Energy drinks can provide quick caffeine and sugar, but they often cause a short-lived boost followed by an energy dip and may elevate heart rate. They can be acceptable in moderated doses for some people but are inferior to timed caffeine plus proper carbohydrate for sustained performance.

Q: What is the best pre-workout snack for strength training? A: A snack combining carbohydrate and a small amount of protein 60–90 minutes before training works well: toast with peanut butter and banana, yoghurt with berries, or a small protein smoothie.

Q: How soon after exercise should I eat? A: Aim to consume a meal or snack containing both carbohydrate and protein within 30–120 minutes after exercise. For most recreational training, a balanced meal within two hours is sufficient.

Q: Can I take creatine only on workout days? A: Creatine’s benefits come from saturating muscle stores, so daily intake (3–5 g) is recommended regardless of training days. Loading phases speed saturation but are optional.

Q: How can I avoid energy crashes mid-workout? A: Avoid relying on pure simple sugars immediately before training. Use moderate glycaemic carbohydrates paired with some protein or fat when possible, time caffeine appropriately, stay hydrated, and practise consistent meal timing to stabilise energy.

Q: I get bloated when I eat before exercise. What should I do? A: Reduce portion sizes, avoid high-fibre and high-fat foods close to exercise, choose liquid or low-residue carbs, and test small snacks during training to find what your gut tolerates.

Q: For marathon training, what should I eat before long runs? A: A carbohydrate-rich meal 3–4 hours pre-run (porridge, toast with honey, banana) is common. During the run, take gels or sports drinks at regular intervals to maintain blood glucose and aid performance.

Q: How can younger exercisers be encouraged to make better fuel choices? A: Increase access to affordable, portable options (fruit, flapjacks, rice cakes), provide education on timing and impacts of sweets/energy drinks, and model healthier choices in group settings.

Q: Are plant-based pre-workout options effective? A: Yes. Oat-based flapjacks, banana and nut butter on toast, and plant-based smoothies provide effective carbohydrate and can be tailored to include protein if needed. Timing and portioning remain important irrespective of dietary preference.

Q: What role do electrolytes play in pre-workout fuel? A: Electrolytes are most important in prolonged exercise or when sweating heavily. For sessions under 60 minutes, water is usually sufficient. For long or hot sessions, include sodium via sports drinks or electrolyte tablets along with carbohydrate.

Q: My schedule means I often skip post-workout food. How can I refuel quickly? A: Keep ready-to-consume options on hand: a protein shake, a yoghurt and fruit pot, a prepared sandwich or a handful of nuts and a banana. Small, convenient choices beat nothing.

Q: Should I avoid fats before training? A: High-fat meals close to workouts can slow gastric emptying and increase GI discomfort, so keep fat moderate when eating within two hours of exercise. Small amounts of healthy fat (e.g., a teaspoon of nut butter) are fine for many.

Q: Can I rely on protein bars as pre-workout fuel? A: Some protein bars work well, but many are high in fibre or fat, which can impair digestion if consumed immediately pre-exercise. Read labels and test individual products in training.

Q: Any final practical tip? A: Experiment systematically. Track what you eat, when you eat it and how sessions feel. Small, consistent adjustments guided by personal feedback lead to the best performance improvements.
