For athletes, food is often described in one simple word: fuel. Carbohydrates provide energy, protein supports recovery, and a balanced diet maintains good performance. This makes nutrition intake seem like a linear process: eat the right foods, avoid the wrong ones, and performance will follow.

But eating is not only a physical process. It's also an emotional one. Food is connected to the brain, emotions, habits and reward system. An athlete might know exactly what they are “supposed” to eat and still find themselves craving food items that they are “not supposed” to eat. A runner may crave something sweet after a long training session. A footballer may want a particular comfort food after a disappointing match. An athlete may automatically reach for the same snack before every competition.
So, why do athletes crave what they crave? The answer is rather complicated than just being hungry.

Hunger vs. Craving

Hunger and craving are not the same thing. Hunger is primarily a physiological signal that the body requires food, whereas a craving is a strong desire for a particular food.

For athletes, cravings can sometimes be a reflection of genuine nutritional needs. Training increases energy expenditure, and inadequate energy intake can leave an athlete physically depleted. If an athlete consistently consumes less than they require, the body may respond with increased hunger and stronger desires for energy-dense or carbohydrate-rich foods. Similarly, inadequate fuelling during training can leave athletes reaching for quick sources of energy later.

However, not every craving means that the body is deficient in a particular nutrient. Cravings can also be influenced by stress, sleep, emotions, habits and environmental cues or to seek comfort.

This changes how we think about cravings. Instead of immediately asking, “How do I stop myself from eating this?”, an athlete could ask, “Why am I craving this right now?”

The Neuroscience of Craving

Food does more than provide nutrients. It also activates the brain's reward and motivation systems.

Highly palatable foods can be rewarding, and repeated experiences with that dish can create associations between particular foods and particular situations. For example, if an athlete regularly has a certain snack after training, finishing a workout can eventually become a cue for wanting that snack. The food is no longer connected only to hunger, it becomes part of the athlete's mental routine.

The cue could be any situation but once the behaviour is repeated often enough, the craving can begin to feel automatic and subconscious. The emotional environment surrounding sport can further add another layer. Good performance involves excitement, pressure, disappointment, anxiety and celebration, and all of these experiences can also influence eating behaviour.

A study examining food cravings among sports spectators found that emotions such as happiness and anger were associated with food craving in particular situations. It provides an interesting demonstration of how emotional experiences surrounding sport can influence the desire to eat. This challenges the common assumption that emotional eating only happens when people are sad or stressed. People may also eat when they are happy, excited or celebrating.

“I had a terrible training session, I deserve this.” Is starkly different from “We won the match, let's celebrate.” The emotions are completely different, but both can create an association between food and emotion.

How the Athlete's Lifestyle Influences Cravings

Athletes have unique schedules that can make them particularly vulnerable to changes in appetite and food choices.

Long training sessions, early mornings, travel, etc. can all affect eating behaviour. Sleep is particularly important. Poor sleep can contribute to fatigue and changes in appetite, making highly rewarding foods more appealing. Stress can have a similar effect. An athlete dealing with performance pressure may turn towards familiar or comforting foods, particularly when food brings pleasure easily.

At the same time, under-fuelling can make cravings more intense. If an athlete spends the day trying to eat as little as possible, only to become extremely hungry at night, the resulting craving should not necessarily be interpreted as a lack of discipline but body's response to inadequate energy intake.

This is where the distinction between physiology and psychology becomes blurred. Hence, understanding an athlete’s psychology becomes just as important in understanding physiology.

Should Athletes Avoid Their Cravings?

One of the problems with nutrition advice is the tendency to divide food into simple categories of “good” and “bad.” While some foods are clearly more nutrient-dense than others, an athlete's nutritional needs depend on the individual circumstances. Carbohydrates, for example, are an important source of energy for many forms of exercise. Protein supports muscle repair and recovery. Healthy fats contribute to energy intake and essential physiological functions. Fruits and vegetables provide vitamins, minerals and fibre, while adequate fluids and electrolytes are important for hydration.

The goal is therefore not to create a list of foods that an athlete can never eat. Instead, athletes need to understand what their body needs and when it needs it. A food may not be ideal immediately before intense exercise because it causes gastrointestinal discomfort, and may be completely appropriate at another time. Similarly a highly palatable food can also be enjoyed by an athlete without necessarily becoming a “guilty pleasure.”

From Craving to Conscious Choice

Understanding cravings can therefore help athletes move away from a mindset of restriction and towards one of awareness.

Before acting on a craving, an athlete can ask, “Am I physically hungry?”, “Have I eaten enough to support my training?”, “Am I tired or sleep-deprived?”, “Am I stressed or emotionally overwhelmed?”, “What will support my body and performance right now?”, “What are better suited alternatives?”

These questions do not require the athlete to reject the craving. They simply create a moment between the craving and the response. If the athlete realises they are genuinely hungry after an intense session, the answer may be to eat a proper recovery meal. If they realise they are craving something because they are stressed after a difficult competition, they might still choose to eat it-  but they may also recognise that they need other forms of recovery, such as rest, social support or relaxation.

Key Takeaways

Food affects athletes on more than one level. It provides the energy required for physical performance, but eating behaviour is also influenced by the brain's reward systems, emotional experiences, learned associations and daily routines. Cravings, therefore, should not automatically be treated as a sign of poor discipline. Sometimes a craving is the body asking for more fuel. Sometimes it is the brain responding to a familiar cue. And sometimes, it is simply because a particular food tastes good. The goal is not to eliminate cravings or achieve perfect control over every food choice. It is to understand them. For athletes, good nutrition is not simply about knowing what to eat. It is also about understanding why they want to eat it. Ultimately, the healthiest approach may look like making a choice that supports both the athlete's performance and the person behind it.
