Your body needs protein for muscle building and repair tissues, so if you aren't eating enough, your muscles won't have the material they need to grow. You could feel “punch drunk” after working out, your arms and other muscles might ache more than usual, and your body may even feel generally weaker.
It is not recommended to workout if you don't have food in your system, as the body needs energy from food to sustain physical activity. Exercise can be taxing on the body and without proper fuel, you may experience weakness, fatigue, and decreased performance.
Exercising without eating well can have various consequences, both short-term and long-term. Exercising without proper nutrition can hinder your performance, slow down recovery, lead to muscle loss, weaken your immune system, and make it challenging to manage your weight effectively.
Yes, it is possible to build muscle even if you don't eat much. However, it is important to make sure that you are still consuming enough protein, as protein is essential for muscle growth. Aim to consume at least 1.4 - 2.0 grams of protein per kilogram of body mass per day.

Eating a meal after your workout is ideal for repairing and building muscle mass and preserving muscle while in a calorie deficit. 6 Not consuming a meal with protein and carbohydrates after your workout means you may miss out on benefits only gleaned during the post-workout window.
Exercising in a fasted state may burn some quick body fat, but it's not the best option for your body in the long-run. Eat a small snack or meal before and after your workout to ensure that you're properly fueled to perform your best in the gym and recover quickly when you get home.
To make gains you have to have the right nutrients in your body to construct muscle. This means that what you eat, and how much, is essential in making muscle gains. Lifting and doing strength training without adequate nutrition, especially without enough protein, can actually lead to loss of muscle tissue.
Yes. But keep in mind that you build muscle with strength training exercises. Such workouts require energy, which means calories, so you may need to maintain only a small deficit. That will allow you to burn fat while still building muscle.
Even if you want to lose body fat, which does require a calorie deficit, cutting calories too much can cause you to lose muscle rather than maintaining muscle while burning fat. Watch out for clear signs that your body isn't getting enough nutrients as a cue to eat more for better gains, Asche said.
“Your heart rate slows, there's less oxygen flow, dizziness, and fatigue.” Undereating can also cause catabolism, or when the body breaks down lean tissue like muscle for fuel, which can lead to loss of muscle mass and muscle wasting. This may be particularly noticeable for athletes experiencing undereating.
Symptoms and warning signs of overtraining
“It's natural and expected to feel fatigued after challenging training sessions,” Dr. Goolsby says. “But feeling like you aren't recovering between sessions or experiencing overall fatigue and difficulty pushing yourself during workouts can be indicators of overtraining.”
If you regularly hit the gym but don't consume adequate protein, your body will struggle to repair and grow muscle tissue effectively. Protein plays a crucial role in muscle growth, recovery, and overall performance.
Whether you work out longer or at a higher intensity, exercise can't completely reverse the effects of a bad diet, expert say. There's also an increased risk for premature death if you exercise but neglect healthy eating.
You can get away with not eating before an exercise session if it is low-intensity or less than an hour. If you haven't eaten for a few hours beforehand, it's important to have a balanced meal soon after (within an hour) to recover and refuel.
Your Metabolism Will Slow Down to Store Fat
It kicks in to preserve and store fat for future energy.
An estimated 2,500 to 2,800 excess calories are needed to gain one pound of lean mass. Of course, this number is highly dependent on individual factors like level of training, starting body composition, genetics, and overall diet.
A low-calorie diet (LCD) involves consuming 1,000 to 1,500 calories per day. This equates to a deficit of approximately 1,000 calories per day. An LCD is considered aggressive, and usually only recommended for people with obesity, and under the supervision of a healthcare provider.
Yes, it is possible to gain muscle while in a calorie deficit, but it depends on several factors such as caloric intake, protein intake, recovery, and weight lifting.
Yes, eating less with a low-calorie diet puts you on the fast track to weight loss—and an intense exercise routine leads to increased metabolism and decreased body fat. In reality, a crash diet and overzealous exercise routine can be hard to maintain which may lead to more weight gain in the future.
Training in a calorie deficit mode is an excellent way to lose weight. The formula here is simple; just reduce your calorie consumption to a level below what your body is consuming, and you're good to go.
That plan is called the 30-30-30 rule. It's a simple but catchy idea that encourages you to eat 30 grams of protein within 30 minutes of waking up and then get 30 minutes of low-intensity exercise. The 30-30-30 rule now has millions of followers on TikTok.
Overall, the experts agree: Exercising in the morning is the best time of day to work out for logistical, effective and health reasons. When it comes to weight loss, a 2023 study published in the journal Obesity found exercising between 7 a.m. and 9 a.m. could help.
The short answer: Many experts suggest having protein after a workout to build muscle mass. But preworkout or postworkout protein may help. Strenuous exercise creates microtears in the muscles. After a workout, your body repairs the damage using amino acids from dietary protein.
