2. Beta-alanine: This one doesn’t directly burn fat, but it does help you work out harder and longer, which in turn lets you melt that extra layer. The non-essential amino acid converts to carnosine, which is one of the strongest buffers against your muscles getting fatigued. Because carnosine keeps your muscles from calling it quits, studies have found beta-alanine can help your performance during HIIT, increase strength, and even help you gain more muscle to then reap all those metabolism boosts.
Cut back on calories. The most important part of losing weight is not working out until you collapse — it's your diet. If you burn 500 to 750 more calories than what you eat every day, you will lose 1–2 pounds every week (any more than that is considered unsafe weight loss). There are tons of little changes you can make to cut calories from your diet, from replacing high-calorie dressings with vinaigrette and asking for all dressings/sauces served on the side, eating at the table instead of in front of the tv, skipping cheese and other fatty additions to your salads and meals, using smaller plates, leave off the whipped cream on your coffee drink, and on and on.
Try this 4-minute rowing circuit: Begin with 20 seconds of rowing followed by 10 seconds of rest. Look at how many meters you traveled in that time. (Don't get off the rowing machine or even let go of the handle when you rest, says Penfold.) Repeat this eight times, trying to beat your distance each time. When you're finished with this four-minute circuit, row a fast 500 meters and note how long it takes you. "That's the number you'll want to match or beat during your next rowing session," says Penfold.
Break up your workouts. Your metabolism spikes after every bout of physical activity. So if you can break up your hour workout into two half-hour chunks, you'll get two spikes instead of one. Your body burns calories at a higher-rate after a workout (sometimes for several hours after), and if you rejuvenate it later in the day, you'll further enhance the effect.
The prevailing formula for a long time on how much fat you’re going to burn was calories in minus calories out, based on your basal metabolic rate (BMR) and exercise efforts, explains strength and performance specialist Joel Seedman, Ph.D., owner of Advanced Human Performance in Atlanta. But with all the different biochemical reactions in the body, hormonal response, and endocrine function, there are an infinite number of factors that can affect how your body is storing and breaking down calories.
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.
How to do burpees: Stand with your feet shoulder-distance apart and send your hips back as you lower your body toward the ground in a low squat. Then, place your hands right outside of your feet and hop your feet back, allowing your chest to touch the floor. Push your hands against the floor to lift your body up into a plank and then jump your feet just outside of your hands. With your weight in your heels, jump explosively into the air with your arms overhead.
