There’s loads of evidence showing how vital nutrition is for exercisefrom aiding performance to enhancing recovery. But it’s often confusing to know whether it’s best to eat before or after you exercise.
To answer this, you need to first consider what you’re training for, as your goal could influence whether to eat before or not. Second, it’s worthwhile to consider the extent that you just’re at. An elite athlete’s needs are different from a beginner and possibly influences how much energy from food is required – and even the variety of meals eaten. Third, it’s worthwhile to take into consideration what works for you. Some people thrive when training in a fasted state, while for others, it’s the alternative.
Eating before
When we exercise, our bodies need energy. This energy is supplied by fuel, either stored in our bodies (as carbohydrate in our liver and muscles, or from fat stores), or from the food we eat. If the exercise is demanding or if we exercise for a very long time, we use more stored carbohydrate (generally known as glycogen).
Studies show that carbohydrates in our food regimen are vital in topping up our glycogen stores between bouts of exercise and in addition when eaten before exercise sessions.
So in case your energy is somewhat low, otherwise you’re doing an extended or more demanding session, consuming carbohydrate-rich foods – similar to pasta, rice, cereals or fruit – around three to 4 hours before exercise might help provide the energy it’s worthwhile to keep moving.
There’s also evidence that carbohydrate type might help improve metabolic responses to exercise. While this may increasingly not necessarily affect performance, eating lower glycemic index foods (foods that produce a slower-releasing carbohydrate effect, similar to porridge oats or wholegrain bread) can higher sustain energy and supply advantages (similar to lower use of glycogen stores) during exercise for some.
But eating right before exercising could cause indigestion, cramps or nausea. Consuming an easily digestible, carbohydrate-rich meal (for instance, porridge with blueberries) around three hours before a training session may help sustain energy and improve training quality without necessarily resulting in gut issues. Pre-fuelling also helps sustain blood sugar levels during exercise, which may positively affect performance.
If your goal is constructing strength or muscle, evidence also suggests that eating protein before exercise may improve overall recovery responses. By providing essential amino acids before they’re needed, this might support early recovery and will be relevant for those undertaking intensive workouts.
Eating after
On the flip side, nonetheless, recent research has demonstrated that training in a fasted state – for instance, very first thing within the morning before breakfast – can actually result in positive adaptations linked with efficient fuel use and fat burning.
This doesn’t necessarily mean greater weight reduction, nevertheless it could optimise fuel efficiency, which could also be vital for those training for a marathon, for instance, to assist delay fatigue. Fasted training could even have other health advantages similar to improved blood sugar and hormone regulation.
But if we predict concerning the point of coaching, it’s all right down to how we recuperate and adapt from it. This is where nutrition has a big role to play. Early research has shown the advantages of eating carbohydrates after exercise to restore muscle glycogen. Not only does this affect our ability to coach repeatedly per week by helping muscles recuperate faster, it’s also shown to affect how well we perform.

Studies have also demonstrated that eating soon after ending exercise (versus waiting for a couple of hours) might help maximise recoveryparticularly if a carbohydrate intake of about 1.3 grams per kilogram of body weight per hour is consumed throughout the two-to-six hour short-term recovery phase. This may very well be useful to know if you happen to are doing one other session that day or inside eight hours.
If your exercise sessions are more unfolded, then early refuelling of carbohydrate is less vitalas long as you aim to fulfill suggested guidelineswhich, for moderate activityis around five to seven grams of carbohydrates per kilogram of body weight a day.
But there’s also an awesome amount of evidence pointing towards the importance of protein feeding during recovery from exercise, each for maximising muscle growthand supporting glycogen replenishment (if protein is consumed with carbohydrates). Research also shows that if training is finished later within the day, then consuming a small protein meal (similar to a shake) before bed also can help with acute recovery resulting in muscle growth.
Before and after
Unless training in a fasted state for a specific reason (similar to for metabolic adaptations or personal preference), there does look like clear benefits for eating before (and through) longer duration exercise. This might also be the case for more trained athletes trying to gain a performance edge. But using nutrition to strategically recuperate must be a must for many who are serious about maximising their workouts.
But what about each? In the case of resistance training, similar to weight lifting, research shows consuming a mix of mainly carbohydrate, protein, and creatine immediately before and after training provided higher muscle and strength gains over ten weeks compared with consuming these nutrients away from training.
While eating after exercise is essential for constructing muscle and recovering between workouts, eating before a workout could also be equally vital for those doing demanding or long workouts. But irrespective of the style of exercise, it’s vital to be certain you’re eating enough carbohydrates, protein and other key nutrients to fuel yourself.
