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.
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.
However, the American Council on Exercise points to research showing that exercise on an empty stomach does not increase the amount of fat burned. The good news is, that there are other techniques you can implement during your two-hour walks that optimize and increase the amount of fat and calories you burn.
In conclusion, the best time to exercise depends on your personal preferences, fitness goals, and schedule. Exercising before a meal can help with weight loss and controlling blood sugar levels, while exercising after a meal can provide the necessary fuel for high-intensity workouts and prevent overeating.
While it's not mandatory to eat after a workout, in general, it's a good idea even when you're not hungry. “Relying only on hunger cues after exercise could be sabotaging your fitness in an inadvertent way,” said Marisa Michael, a registered dietitian nutritionist who specializes in sports nutrition.
If you don't eat, you might feel slow-moving or lightheaded when you exercise. If you plan to exercise within an hour after breakfast, eat a light meal. Or have a sports drink. Focus on carbohydrates for the most energy.
Schlichter points to a review of 46 studies published in the Scandinavian Journal of Medicine & Science in Sports, which found that eating before exercise was beneficial for performance for aerobic workouts lasting more than an hour—though fasting before shorter workouts wasn't found to be detrimental.
Activities like running, cycling, and high-intensity interval training (HIIT) burn more calories and fat throughout the body, including the upper belly, lower belly, and obliques. So, while ab exercises can help define your core, it's a holistic approach that will help you lose the fat covering those muscles.
Eating a big meal too close to your workout may lead to stomach upset, bloating, and impaired performance. Aim for a 2–3 hour window between eating a larger meal and working out. This will give your body enough time to digest the food, absorb essential nutrients, and provide sustained energy during exercise.
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.
Nutrient Deficiency. Lack of nutrients: Skipping a pre-workout meal means missing out on essential nutrients that could support muscle recovery and growth.
Hunger alone cannot exactly burn fat. Just being hungry does not mean your body is burning fat. The body uses sugar for energy in case of hunger and not the fat reserve. It might play a small role, though.
The results showed that, similar to exercise after an overnight fast, fasted exercise in the evening increased the amount of fat burned during exercise. The amount of fat burned during the 30-minute cycle increased by about 70% from 4.5g to 7.7g.
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.
When you eat right before exercising, your body is going to first use the calories you just consumed for fuel. By exercising when it's been about three to four hours since you last ate, your body is more able to burn fat for fuel because other easier methods of fuel aren't available.
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.
A: Bananas, apples, berries, pineapple, oranges, and watermelon are some of the best fruits to consume before a workout as they provide quick energy, essential nutrients, and hydration.
Time It Right
You can have tummy troubles if you chow down right before. That's because more blood goes to your muscles during exercise, leaving less for digestion. After exercise, your body is ready to refuel and rebuild muscle tissue. Eat or drink within an hour of finishing.
Exercising without food and fuel leads to decreased energy levels, making it challenging to give your 100% to the workout. Which may in turn result in shorter or less intense workouts. In some extreme cases, fasted workouts lead to muscle breakdown as the body seeks alternative energy sources.
