What to Eat Before, During, and After Training: A Complete Nutrition Guide

Aug 3, 2026 Jayme Cunningham

Key Takeaways:

Carbohydrates are the most timing-sensitive macronutrient around training. Prioritise them before and after exercise.
Protein total daily intake matters most. Distribute it evenly across meals, including your post-workout window.
Post-exercise glycogen replenishment is critical for recovery, especially if you train frequently.
Hydration and electrolytes are performance variables, not afterthoughts.
Supplements like Creatine Complex, Grassfed Whey Protein, Performance Fuel, Cell Fuel, Prime Day, Prime Night, and Inflammation Complex can support your nutrition strategy without replacing it.

Most people know they should eat around their workouts. Fewer know why timing matters, what to prioritise, or how to make it practical without overcomplicating every meal. This guide cuts through the noise and gives you a research-based framework you can actually use.

Whether you are new to structured training or have been lifting and running for years, understanding peri-workout nutrition can make a meaningful difference to your energy levels, performance, and recovery. And it does not require a nutrition degree to get right.

Why Nutrient Timing Matters

Nutrient timing refers to when you consume specific macronutrients relative to exercise, and the evidence supporting its importance is well-established. Exercise increases the demand for energy, increases muscle protein breakdown, depletes glycogen stores, and elevates metabolic rate. What you eat before, during, and after training directly affects how well your body manages each of these processes.

The key insight from research is that not all nutrients are equally time-sensitive. Carbohydrates are highly responsive to timing around exercise. Protein, on the other hand, is governed more by total daily intake and even distribution across meals. Understanding this distinction helps you build a nutrition strategy that is both effective and sustainable.

In a study it describes the peri-workout period as a window that can amplify training adaptations when managed correctly. This does not mean rigid meal timing for everyone, but it does mean that the quality and composition of what you eat before and after training has real, measurable effects on your results.

Peri-Workout Nutrition at a Glance

Phase	Priority Nutrient	Purpose
Before Training	Carbohydrates	Fuel working muscles and top up glycogen stores
Before Training	Moderate Protein	Reduce muscle breakdown during training
During Training	Carbohydrates + Electrolytes	Sustain energy output and prevent dehydration
After Training	Carbohydrates + Protein	Replenish glycogen and trigger muscle protein synthesis

Before Training: Fuelling for Performance

The pre-workout meal has one primary job: make sure your body has enough available energy to perform at its best. Secondary to that is limiting muscle breakdown during the session and reducing post-exercise recovery demands.

Carbohydrates Come First

Skeletal muscle and the liver store carbohydrates as glycogen. During moderate to high-intensity exercise, glycogen is the dominant fuel source. When glycogen stores are low, performance drops, fatigue sets in earlier, and training quality suffers. Pre-workout carbohydrate intake helps top up these stores and ensures glucose is readily available during the session.

Research confirms that carbohydrate availability before exercise significantly influences sustained endurance and power output. This is true whether you are doing strength training, high-intensity intervals, or longer aerobic sessions. The type of carbohydrate matters less than total availability, though easier-to-digest sources are preferable close to training.

A practical pre-workout meal consumed 2 to 3 hours before training might include oats with a piece of fruit, rice with a lean protein source, or a wrap with chicken and vegetables. If eating within 60 minutes of training, smaller portions of easily digestible carbohydrates like a banana, rice cakes, or a sachet of Performance Fuel work well.

Protein Before Training: Useful, Not Critical

Including protein in your pre-workout meal supports muscle protein synthesis and reduces protein breakdown during training, particularly in resistance exercise. A study found that consuming essential amino acids before resistance training elevated muscle protein synthesis during the session itself.

That said, pre-workout protein is less time-sensitive than post-workout carbohydrates. If your previous meal included protein and was consumed within three to four hours before training, you do not need to add more protein directly before your session. A moderate amount of 20 to 40 grams from a whole food source is sufficient when eating a full pre-workout meal.

Fats Before Training: Limit Close to Exercise

Fat slows gastric emptying and can cause discomfort during high-intensity training. A small amount of fat in a meal consumed 2 to 3 hours before training is fine, but eating a high-fat meal within 60 to 90 minutes of training is not ideal. Keep pre-workout fat intake moderate and let carbohydrates take the lead.

Pre-Workout Hydration and Electrolytes

Arriving at your workout in a well-hydrated state is one of the simplest performance levers available. Even mild dehydration of around 2 percent body mass loss has been shown to impair cognitive function, reaction time, and muscular endurance. Drink 400 to 600 ml of water in the 2 hours before training and continue sipping up to your session start.

Electrolytes are not just a during-exercise concern. Sodium, potassium, and other key minerals support fluid balance and muscle function throughout the day. Starting your training session with optimal electrolyte status, rather than playing catch-up mid-session, is a straightforward advantage.

PrimeSelf Supplement Spotlight: Prime Day

PrimeSelf Prime Day is an all-in-one daily performance sachet combining precision-dosed nootropics, essential vitamins, minerals, and a premium electrolyte blend, including Pink Himalayan Salt and Potassium Citrate, to support hydration, focus, and daily vitality. It is sugar-free, stimulant-free, and formulated to serve as a clean daily foundation for anyone who trains. Taking Prime Day in the morning or before training ensures your electrolyte levels are topped up and your mental sharpness is supported before you even start warming up.

When to take: Mix 1 sachet with 300 to 500ml of water in the morning or 15 to 30 minutes before training. Safe for daily use.

PrimeSelf Supplement Spotlight: Performance Fuel

If you train early in the morning or cannot eat a full pre-workout meal, a sachet of PrimeSelf Performance Fuel mixed with 500 to 750 ml of water provides 30g of dual-source carbohydrates in a researched 1:0.8 glucose to fructose ratio, alongside a meaningful electrolyte dose to support hydration and sustained output. It is designed to fuel training without sitting heavy in the stomach.

When to take: 15 to 30 minutes before training. For longer sessions, sip during the session as well.

PrimeSelf Supplement Spotlight: Cell Fuel

PrimeSelf Cell Fuel supports endurance, oxygen utilisation, and training capacity using Peak O2, an adaptogenic mushroom blend, alongside SalidroPure Rhodiola and Astragalus Root. Rather than stimulating the nervous system, it works by improving the body's underlying ability to produce energy, manage fatigue, and recover between sessions. Benefits build over consistent use.

When to take: 30 to 60 minutes before training. Take daily, even on rest days, for cumulative benefits.

PrimeSelf Supplement Spotlight: Creatine Complex

Most creatine products use a single form of creatine monohydrate. PrimeSelf Creatine Complex combines two distinct forms: pure creatine monohydrate and MagnaPower Creatine Magnesium Chelate, a patented creatine bound to magnesium rather than water. This dual-formula approach supports ATP regeneration and strength output while also delivering 250mg of elemental magnesium per serving, a mineral essential for muscle contraction, energy production, and recovery that most standalone creatine products do not include. Like every PrimeSelf product, Creatine Complex is finished-product tested, meaning the final product, not just the raw ingredients, is independently verified for label accuracy and purity before it reaches you.

When to take: Creatine can be taken at any time of day. Consistency matters more than exact timing. Take 3-5g daily for women, and 5-10g daily for men.

During Training: Sustaining Energy and Hydration

For most sessions under 60 minutes, a solid pre-workout meal and adequate hydration will carry you through without needing additional fuel mid-session. However, for longer, higher-intensity training lasting 60 minutes or more, in-session nutrition becomes increasingly important.

Carbohydrates During Exercise

When training extends beyond 60 to 75 minutes, glycogen availability starts to limit performance. Consuming carbohydrates during exercise, typically 30 to 60 grams per hour for moderate-intensity sessions and up to 90 grams per hour for high-intensity endurance work, sustains energy and delays fatigue.

Research supports a dual-transporter carbohydrate approach during longer sessions, using a combination of glucose and fructose sources. This is because glucose and fructose use different intestinal transporters, allowing higher total carbohydrate absorption rates with reduced gastrointestinal stress. A study demonstrated that dual-source carbohydrate intake can improve performance by up to 8 percent compared to glucose alone in prolonged exercise.

Electrolytes During Exercise

Sweat contains more than water. Sodium, potassium, magnesium, and chloride are lost in meaningful quantities during sustained exercise, and failing to replace them accelerates fatigue, increases cramping risk, and impairs muscle function. Sodium is particularly important as it drives fluid retention and maintains plasma osmolality.

For sessions under 60 minutes in moderate conditions, water is usually sufficient. For longer sessions, hot conditions, or high sweat rates, an electrolyte-containing drink makes a practical difference.

PrimeSelf Supplement Spotlight: Performance Fuel (During Training)

Performance Fuel is equally effective as an in-session fuelling strategy that provides 30g of dual-source carbohydrates in 1 simple sachet. Its 1:0.8 glucose to fructose ratio supports higher carbohydrate absorption rates while minimising gut stress, and its electrolyte profile, including 500mg sodium and 250mg potassium per sachet, replaces real sweat loss. Sip throughout longer sessions to maintain energy and hydration.

When to take: Sip during sessions lasting 60 minutes or more. For sessions over 90 minutes, a second sachet mid-session is appropriate.

After Training: Recovery Starts Here

The post-workout period is arguably the most important nutritional window of the day for anyone training with consistency and intent. During exercise, muscle glycogen is depleted, muscle tissue sustains micro-damage, and the body enters a heightened state of metabolic sensitivity. What you consume in the hour following training directly influences how well you recover, how quickly you are ready to train again, and the extent of your adaptations over time.

Glycogen Replenishment: The Priority After Exercise

Replenishing glycogen stores is the number one nutritional priority following training, especially if you train on consecutive days or more than once per day. During exercise, glycogen synthase activity is elevated, making the post-exercise window a time of increased carbohydrate uptake efficiency. The sooner carbohydrates are consumed after training, the more rapidly glycogen stores are restored.

A study showed that consuming carbohydrates immediately after exercise led to significantly faster glycogen synthesis compared to delaying intake by two hours. For those training once daily with adequate recovery time between sessions, this urgency is less critical. For anyone training frequently, this timing window is meaningful.

Post-workout carbohydrate targets typically range from 1 to 1.2 grams per kilogram of body weight in the first hour after training for rapid glycogen replenishment. High-glycaemic index sources are particularly effective during this window due to their faster absorption rates. Practical options include fruit, rice cakes, potatoes, white rice, bread or a carbohydrate-containing recovery drink.

Protein After Training: Building and Repairing

While carbohydrates lead the post-workout nutrition conversation, protein plays an equally essential role. Exercise, particularly resistance training, stimulates muscle protein synthesis, but also increases muscle protein breakdown. Net muscle gain occurs only when synthesis exceeds breakdown. Adequate post-workout protein tips that balance in your favour.

Research consistently supports consuming 20 to 40 grams of high-quality protein in the post-workout period to maximally stimulate muscle protein synthesis. Leucine, an essential amino acid abundant in whey protein, is the primary trigger for muscle protein synthesis through the mTOR pathway. Whole food sources like eggs, chicken, fish, or dairy work well. Whey protein is also a practical and well-researched option, particularly when appetite is low following intense training.

Critically, total daily protein intake is the strongest predictor of muscle protein synthesis over time. The post-workout window matters, but it is more important to hit your daily protein target across the day than to stress over the exact post-workout timing. A general target of 1.6 to 2.2 grams of protein per kilogram of body weight per day is supported by the current research.

The Carbohydrate-to-Protein Ratio After Training

Combining carbohydrates and protein after training is more effective than either macronutrient alone. Insulin released in response to carbohydrate intake promotes amino acid uptake into muscle tissue and supports anabolic signalling. A practical ratio of 2:1 to 3:1 carbohydrates to protein is commonly recommended for post-exercise recovery meals, though the total amounts matter more than the ratio itself.

A meal of white rice with grilled chicken and roasted vegetables, a smoothie with banana, oats, and whey protein, or toast with eggs and fruit all fit this model and provide the combination of carbohydrates and protein the body needs post-exercise.

PrimeSelf Supplement Spotlight: Grass-Fed Whey Protein

PrimeSelf Grass-Fed Whey Protein delivers 20g of protein per serving from a 50/50 blend of whey isolate and concentrate, enhanced with Orafti Inulin prebiotics and Digezyme digestive enzymes for improved gut comfort and nutrient absorption. It is hormone-free, ISO-certified, and Halaal Certified, making it a clean, practical post-workout protein source.

When to take: Within 30 to 60 minutes after training, mixed with water or milk. Can be combined with a banana or oats for a complete post-workout recovery meal.

PrimeSelf Supplement Spotlight: Inflammation Complex

Training creates controlled inflammation as part of the adaptation process. However, chronic or excessive inflammation impairs recovery and limits subsequent training quality. PrimeSelf Inflammation Complex combines Curcumin C3 Complex, MSM, Cat's Claw, and Quercetin Dihydrate, enhanced with BioPerine for improved absorption, to support the body's healthy inflammatory response, joint comfort, and post-exercise recovery.

When to take: Daily, ideally with a meal. Particularly useful during periods of high training volume or when managing exercise-related joint discomfort.

Overnight Recovery: The Role of Magnesium and Electrolytes

Recovery does not stop when you leave the gym. The hours between training and the next session, particularly overnight, are when much of the body's repair and adaptation work takes place. Sleep quality directly influences muscle protein synthesis, hormone balance, and readiness for subsequent training sessions. Magnesium plays a central role in this process.

Magnesium is involved in over 300 enzymatic reactions in the body, including those governing muscle relaxation, protein synthesis, and nervous system recovery. Research has shown that magnesium deficiency is associated with impaired sleep quality and increased muscle cramp frequency, both of which are especially relevant for people who train regularly. Replenishing magnesium and electrolytes in the evening supports the overnight recovery process that daytime nutrition alone cannot fully address.

PrimeSelf Supplement Spotlight: Prime Night

PrimeSelf Prime Night is an all-in-one evening recovery sachet combining multiple forms of magnesium (Magnesium Bisglycinate, L-Threonate, and DiMalate) with calming nootropics including L-Theanine, GABA, and Apigenin, plus an electrolyte blend of Pink Himalayan Salt and Potassium Citrate. Together, these support muscle relaxation, nervous system recovery, sleep quality, and overnight restoration. For athletes and active individuals, Prime Night addresses the recovery gap that food alone rarely fills, delivering meaningful magnesium and electrolyte replenishment precisely when the body is doing its most important repair work.

When to take: Mix 1 sachet with 300 to 500ml of water 30 to 60 minutes before bed. Use nightly for consistent recovery benefits.

Your Full-Day Nutrition Guide: From Morning to Bed

All three phases, before, during, and after training, work as a connected system. What you eat in the morning affects your training session. What you eat after training affects how well you sleep and how ready you are the next day. The table below brings the full picture together so you can see exactly what a well-structured training day might look like across both profiles.

These examples are practical starting points, not rigid prescriptions. Adjust portion sizes to your body weight, training volume, and appetite. The key is consistency across the full day, not perfection at any single meal.

Timing	Everyday Gym-Goer	Endurance Athlete
Morning	Prime Day sachet + creatine in 400ml water.	Prime Day sachet + creatine in 500ml water.
Pre-Training	2-3 hours before: a balanced meal with carbohydrates and protein (oats and eggs, rice and chicken). 30 min before: banana or 1-2 rice cakes with honey. Short on time: Performance Fuel sachet instead.	2-3 hours before: a higher-carb meal (sweet potato or white rice with a protein source). 30-45 min before: toast & honey and a banan or Performance Fuel sachet. Cell Fuel capsules 45 min before for endurance support.
During Training	Sessions under 60 min: water only (500ml per hour). Sessions over 60 min: sip Performance Fuel throughout to maintain energy and electrolytes.	Sip Performance Fuel from the 20-minute mark. For sessions over 90 min, a second sachet mid-session. Aim for 400-600ml fluid per hour.
Post-Training	Within 30-60 min: Grass-Fed Whey Protein shake with a banana. Follow with a balanced meal when appetite allows.	Within 20-30 min: Grass-Fed Whey Protein shake with banana and oats for fast carbohydrate and protein delivery. A larger meal within the hour.
Before Bed	Prime Night sachet 30-60 min before sleep. Supports muscle relaxation, electrolyte replenishment, and sleep quality.	Prime Night sachet 30-60 min before sleep. Supports nervous system recovery, muscle relaxation, and sleep quality after demanding sessions.

A few things worth noting about both profiles: neither requires obsessive tracking, neither skips food groups, and both are built around real, accessible foods with targeted supplementation where it adds genuine value. The endurance athlete leans into more carbohydrates because the demand is higher. The gym-goer keeps portions moderate because session length and glycogen depletion are lower. The principles are the same across both. The quantities shift.

Key Daily Targets to Aim For

Total protein: 1.6 to 2.2g per kg of body weight, distributed across 3 to 5 meals
Carbohydrates: Higher on hard training days, lower on rest days. Endurance athletes will need significantly more than gym-goers on long session days.
Hydration: Minimum 2 to 3 litres daily, more on heavy training days or in warm conditions
Creatine: 3-5g for women and 5-10g for men daily at any time, consistently
Prime Day: 1 sachet daily in the morning for electrolytes, vitamins, and focus
Prime Night: 1 sachet nightly for magnesium, electrolytes, and overnight recovery support

Putting It Together

Workout nutrition does not need to be complicated, but it does reward consistency and intentionality. Carbohydrates are your primary training fuel and your fastest recovery tool. Protein supports the repair and growth that makes training worthwhile, but it is more important for you to hit your overall protein daily intake than the timing. Hydration and electrolytes are the often-overlooked variables that affect both performance and recovery, during the session and long after it ends.

Get the fundamentals right across the full day, and everything else, your energy, your output, your recovery, tends to follow. Food comes first. Supplements fill the gaps. And the routine you can actually stick to is always the one that works best.

The PrimeSelf range is built to support each part of that routine, from morning to training to sleep, without replacing the basics or overcomplicating what is already working.

Better You, Every Day.

Frequently Asked Questions

Do I need to eat immediately after training?

If you train frequently, including on consecutive days, consuming carbohydrates and protein within 30 to 60 minutes post-exercise supports faster glycogen replenishment and initiates muscle protein synthesis efficiently. If you train once per day with adequate time between sessions, eating within a couple of hours is fine, provided you hit your daily targets.

Are carbohydrates or protein more important after training?

Both matter, but for different reasons. Carbohydrates are the primary driver of glycogen replenishment, which is the top post-exercise nutritional priority. Protein triggers muscle protein synthesis and supports tissue repair. A combination of both is more effective than either alone. Prioritise carbohydrates first, then ensure adequate protein is included.

Can I train fasted?

Fasted training is possible and some people prefer it. However, research suggests that having some carbohydrates available before training supports higher training quality and output, particularly for moderate to high-intensity sessions. For shorter, lower-intensity sessions, fasted training is unlikely to significantly affect performance. For more demanding sessions, some form of pre-workout carbohydrate intake, even something small like a banana or a sachet of Performance Fuel, is worth considering.

How much protein do I actually need each day?

Current evidence supports a range of 1.6 to 2.2 grams of protein per kilogram of body weight per day for individuals engaging in regular resistance training. Spreading this across 3 to 5 meals supports a more consistent anabolic stimulus throughout the day.

Why does magnesium matter for recovery?

Magnesium is involved in muscle relaxation, protein synthesis, and hundreds of enzymatic processes that support recovery. Many people who train regularly are mildly deficient due to sweat losses and dietary gaps. Replenishing magnesium in the evening, through diet and a product like Prime Night, supports muscle relaxation, sleep quality, and the overnight recovery process that follows every training session.

What does Performance Fuel do that a regular sports drink does not?

Performance Fuel is formulated around a research-backed 1:0.8 glucose to fructose ratio, which allows higher carbohydrate absorption rates while reducing gastrointestinal stress during training. Many commercial sports drinks rely primarily on glucose or sucrose, which limits total absorption rate and increases gut discomfort at higher doses. Performance Fuel also delivers a meaningful electrolyte dose, including 500mg sodium and 250mg potassium, to support real-world hydration needs.

Is whey protein effective for muscle recovery?

Whey protein is among the most researched and effective protein sources for supporting muscle protein synthesis. Its high leucine content and rapid absorption rate make it particularly well-suited to the post-workout period. PrimeSelf Grass-Fed Whey Protein also includes Digezyme digestive enzymes and Orafti Inulin prebiotics to support gut comfort and nutrient absorption.
