Is Working Out On an Empty Stomach Bad for You? According to Roper, fasted exercise is generally safe for most people, but it may lead to side effects. “Because blood glucose gets depleted during fasting cardio, you can experience some side effects including lightheadedness and dizziness,” she said.
Working out on an empty stomach in the morning can be beneficial for fat loss, as it taps into stored glycogen and promotes fat utilization. However, for muscle building, having a small meal with protein before may be more effective. Listen to your body, experiment, and find what works best for you.
Increased Fatigue: Exercising on an empty stomach may lead to quicker onset of fatigue, making it harder to complete your workout effectively. Potential for Dizziness or Lightheadedness: Low blood sugar levels from not eating can cause dizziness, lightheadedness, or even fainting during exercise.
Working out in the morning is generally safe and can offer benefits like improved mood, energy levels, and metabolism throughout the day. However, listen to your body's signals, warm up properly, and stay hydrated to reduce the risk of injury.
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.
If you exercise in the morning, get up early enough to finish breakfast at least one hour before your workout. Be well fueled going into a workout. Studies suggest that eating or drinking carbohydrates before exercise can help you do better during your workout.
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.
It is when the timing pattern of our workout becomes erratic that elicits a negative response to a positive stressor like exercise. If you're going to make the early morning workout your routine, then waking up at least an hour before training is your best bet for your body to adjust to a new the circadian rhythm.
The mechanism through which this occurs is an increase in VO2 max, which is the maximum amount of oxygen used during exercise. Fasted cardio has been shown to increase your ability to take in and deliver oxygen to your muscles, allowing you to train harder, especially during high intensity training sessions.
Nutrient Deficiency. Lack of nutrients: Skipping a pre-workout meal means missing out on essential nutrients that could support muscle recovery and growth.
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.
Further, 'fasted workouts' improve insulin sensitivity making it easier for the body to manage blood sugar levels. The cons on the other hand are of reduced performance and at times muscle loss. Exercising without food and fuel leads to decreased energy levels, making it challenging to give your 100% to the workout.
Lifting and doing strength training without adequate nutrition, especially without enough protein, can actually lead to loss of muscle tissue. Furthermore, if you aren't eating right you won't have the energy to do the workouts that lead to muscle gain.
Here are some things to consider: Exercising on an empty stomach can help you burn more body fat for fuel. When you eat right before exercising, your body is going to first use the calories you just consumed for fuel.
You might be wondering, how long does it take for your stomach to empty? After a meal, it normally takes around 1 hour and 30 minutes to 2 hours for your stomach to empty. But, the type of meal you eat plays a role in how fast it moves through your stomach.
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.
Blood sugar levels are lower after a night of sleep, so you can feel tired and sluggish during your workout if you skip breakfast. For this reason, a small healthy snack before working out in the morning will help your blood sugar levels increase enough to give you the energy you need for top performance.
Fasting combined with physical activity did not affect the effects of training on muscle performance.
When you exercise in a fasted state — after a night's sleep and before you eat breakfast — then you do actually use more fat as a fuel source during exercise. But research from my team has shown that performing exercise in a fasted or fed state does not have any meaningful impact on body fat in the medium to long term.

Traditionally, experts have recommended not exercising at night as part of good sleep hygiene. However, a small study, published in Sports Medicine suggests that some people can exercise in the evening as long as they avoid vigorous activity for at least one hour before bedtime.
Exercising in the morning can lead to increased alertness and mental clarity, which may enhance productivity throughout your day. However, it's important to warm up properly, as the body's muscles are typically colder and tighter in the morning.
Ideally, include carbs such as a banana, low-fat yogurt, bowl of cereal, smoothie or a glass of milk. Avoid foods that are high in fat or fibre because they take longer to digest and may cause stomach discomfort during exercise.
