According to one meta-analysis, up to 45 percent of athletes experience low energy availability, or 'undereating', highlighting a prevalent issue beyond just elite sports. Far from optimizing results, working out without adequate fuel can have serious repercussions on your body and fitness goals.

According to the National Institutes of Health, low body weight or rapid weight loss can disrupt a woman's menstrual cycle, potentially halting ovulation and causing her period to stop entirely. This happens because the body interprets malnutrition as a state of stress, prioritizing essential functions like breathing over non-essential ones like reproduction.

According to a study in *Sports Medicine*, the symptoms of underfueling and overtraining are almost identical, making it crucial for active individuals to learn how do I know if I'm eating enough while working out. Recognizing the subtle signals your body sends is the first step toward optimizing your energy, performance, and recovery.

The body is incredibly resilient, but prolonged and severe food deprivation, or starvation, triggers a cascade of survival mechanisms with devastating consequences. This extreme state of caloric restriction drastically alters bodily functions, prioritizing energy for vital organs by cannibalizing fat and muscle stores. Understanding what happens to your body when you barely eat is crucial for recognizing the dangers of severe malnutrition and seeking help.

According to a systematic review published in 2024, nearly 45% of athletes across various sports were found to have low energy availability (LEA). So, how do I know if I have low energy availability? This condition occurs when energy intake doesn't match energy expenditure, forcing the body to conserve energy by compromising critical functions like metabolic rate, bone health, and hormone production. Recognizing the warning signs is the first crucial step toward protecting your health and athletic performance.

The body’s primary energy stores, muscle glycogen, can become depleted during periods of intense training, leading to a state of fatigue known as overtraining syndrome. To counter this, understanding what should I eat if I'm overtraining is paramount for proper recovery and reversing performance decline.

According to researchers at Penn State, collegiate runners with chronic energy deficiency showed compromised performance and slower race times. An energy deficit, also known as a caloric deficit, occurs when the body expends more calories than it consumes, and while a moderate deficit is used for weight loss, a severe or prolonged one can have significant health consequences.

According to evolutionary biology, the human body is expertly designed to handle periods of food scarcity. The idea that your body stores food if you don't eat is a common misconception, but the biological reality is far more complex and involves a strategic shifting of energy sources to conserve energy and manage the energy deficit.

According to research, exercising in a massive calorie deficit can cause health issues like fatigue, poor performance, and even muscle loss. So, what happens if I exercise but don't eat enough, and what are the signs you should look for? The risks extend far beyond just feeling a bit tired during your workout.

According to MD Anderson Cancer Center, a calorie deficit occurs when you burn more calories than you consume, a principle central to weight management. This approach is often referred to as an energy deficit diet, and it leverages your body's energy reserves to fuel daily functions, leading to weight loss over time.
