6. Fast once a week: While regularly underfeeding your body completely messes with your hormone balance, there’s sufficient research to suggest that intermittent fasting (IF)—or going without any food for set intervals—can actually help your insulin sensitivity and burn more fat. Researchers at LSU, for example, found that when people fasted all day, every other day, their fat oxidation increased and they actually lost 4 percent of their body fat in just 22 days. There are a lot of ways to go about IF, from fasting for 12 to 16 hours every day, to going 24 hours once a week. (Learn more about it here.)
Drinking whey protein as a between-meals snack is a smart way to enhance not only muscle growth but also fat loss. UK researchers found that when subjects consumed a whey protein shake 90 minutes before eating a buffet-style meal, they ate significantly less food than when they consumed a casein shake beforehand. The scientists reported that this was due to whey’s ability to boost levels of the hunger-blunting hormones cholecystokinin and glucagon-like peptide-1.
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.
Eat small meals more often. In simple terms, eating spurs your metabolism — the process by which your body turns food into energy. Eating more often, then, may kick your metabolism into a higher gear more times per day (e.g., if you eat six times a day, you get six “spikes”). But, you must make sure that eating more often does not also mean eating more; it's essential that you reduce your overall average daily calories.
Cut back on carbs: Remember how insulin has the biggest impact on fat storage? Well, carbs have the biggest impact on insulin. ”Too many carbohydrates leads to a spike in the hormone and then to more fat storage,” Seedman explains. Not only should you cut back on carbs, but your insulin will spike even more from processed ones, so cut any carb that’s not a whole grain or from real produce completely. And don’t worry: Carbs are traditionally thought of as your body’s main source of energy, but your body also has the ability to fuel from fat, so if you’re increasing your fat and protein intake, your body doesn’t need as many carbs to run. You still need some amount of carbohydrates to regulate certain biological processes, like your muscles’ ability to stay hydrated and maintain structural integrity, so don’t cut the macronutrient completely, Seedman warns. For a high-fat, low-carb diet, aim for at least .5 of your bodyweight (so a 200 lb person would eat at least 100 grams of carbs per day), he suggests. For a more balanced calorie-restricted diet, that number jumps to .75 to 1.5 grams per pound of bodyweight.
How to do lateral medicine ball slams: Stand with your feet about shoulder-width apart with the medicine ball on one side. Pick up the ball and simply rotate your body as you slam the ball a few inches away from your pinky toe. Make sure to pivot your feet and bend the back knee as you come into a split squat position to catch the ball on one bounce. Alternate sides. Make sure you tighten your core as you bring the ball overhead and to the side.
There are a variety of definitions of what moderate-intensity exercise is, but it typically falls between about 70 to 80 percent of your maximum heart rate, which would be a level 4 to 6 on a 10-point perceived exertion scale. That means you are breathing harder than normal but can carry on a conversation without much difficulty and you feel pretty comfortable with what you're doing. The American College of Sports Medicine (ACSM) often recommends this level of intensity in its exercise guidelines. The lower end of this range usually incorporates the fat burning zone.
