For our purposes here, high-intensity cardio falls between about 80 to 90 percent of your maximum heart rate (MHR) or, if you're not using heart rate zones, about a 6 to 8 on a 10-point perceived exertion scale. What this translates to is exercise at a level that feels challenging and leaves you too breathless to talk in complete sentences. But you're not going all out, as in sprinting as fast as you can. There's no doubt that some high-intensity training work can be helpful for weight loss as well as improving endurance and aerobic capacity.
If you feel like any extra calories you eat go straight to your belly or thighs, you're not imagining things. Those are usually the areas where you store fat because of your genes, hormones, age, lifestyle, and other factors. Your body tends to hoard calories as fat to keep you alive and safe. The challenge is learning how to get rid of that extra fat.
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.
How to do a sprawl: Standing with your feet shoulder-distance apart, squat down and place your hands on the ground. Jump your feet back to a plank and lower your body to touch the ground. Push yourself up to a plank and then jump your feet outside of your hands into a squat. Stand back up. That’s one rep. “If you want to burn even more calories, add a jump between each sprawl,” Braganza adds.
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.
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.
Ansari says alcohol can prevent weight-loss in several ways, including the fact that heavy alcohol intake can stimulate food intake. "Binge drinking can overload the liver. The liver then prioritizes processing alcohol over other nutrients and then stores the protein, carbs, and fat as fat in the body," Ansari explains. The Centers for Disease Control and Prevention (CDC) defines binge drinking as having five or more drinks for men, and four or more drinks for women in two hours. "Also, alcoholic beverages are often mixed with sugar-rich beverages. Drinking more than moderate amounts of alcohol can cause calories to add up quickly."
