1. Don’t starve yourself: Cortisol—that stress hormone that causes your body to store more fat—is elevated from circumstances of high stress, including extreme dieting, Seedman says. “If you start dropping calories excessively, your body goes into starvation mode and it becomes stressed. You’re in caloric deprivation, but that elevated cortisol causes you to gain body fat in your stomach—it’s a vicious cycle,” he adds.
DO IT: Assume a pushup position with your hands below your shoulders and your body forming a straight line from your head to your heels. This is the starting position. Lifting your right foot off of the floor, drive your right knee towards your chest. Tap the floor with your right foot and then return to the starting position. Alternate legs with each repetition.
To avoid feeling hungry after a workout, eat a snack with at least 12 grams of protein before exercising, says Dr. Cheskin. And if you’re still hungry afterward? First, check in with yourself and make sure it’s actual hunger and not dehydration, says Dr. Cheskin. Then, eat a protein-rich snack that also includes some carbs, like a protein bar with whole grains.
You may be confused about exactly how hard to work during cardio. You may even think that high-intensity exercise is the only way to go. After all, you can burn more calories and, even better, you don't have to spend as much time doing it. But having some variety can help you stimulate all of your different energy systems, protect you from overuse injuries, and help you enjoy your workouts more. You can use a sample cardio workout schedule to set up a cardio program that includes a variety of different workouts at different intensities.
Interval Training: A great way to incorporate high-intensity training without doing it continuously is by doing intervals. Alternate a hard segment (e.g., running at a fast pace for 30 to 60 seconds) with a recovery segment (e.g., walking for one to two minutes). Repeat this series for the length of the workout, usually around 20 to 30 minutes. A 30-60-90 interval workout is a good example of this kind of high-intensity workout.
4. Eat more protein: Upping your protein is crucial for shedding fat. For starters, the macronutrient helps keep you full, preventing overeating and extraneous calories. And without adequate amounts of the macronutrient, muscle protein synthesis is diminished, your muscles can’t rebuild bigger and stronger, and your resting metabolism is lowered, says nutrition specialist and exercise physiologist, Marta Montenegro, CSCS, adjunct professor in Exercise & Sports Sciences at Florida International University. Plus, it gives your calorie burn a little boost since protein takes more energy for your body to process than carbs or fat.
There’s a reason everyone harps on about protein: Not only does it help keep you full, but it’s also responsible for repairing the tiny tears caused by strength training in your muscles. This helps them grow bigger and stronger, nudging out body fat in the process. As a general rule of thumb, aim to get at least 70 grams of protein throughout the day, says Dr. Cheskin.
