If your walking workout helps you unwind after a stressful day or work through emotions that might otherwise stress you out, there's a chance it'll help you lower cortisol levels, which in turn can keep belly fat in check, says Gonzalez. And brisk walking is an effective way to drop pounds—including the belly fat that's hiding your abdominal muscles. "One hour of rapid walking a day can lead to one pound of fat loss a week," says Gonzalez.
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.
This may explain why the fat-burning effects of eating more protein were confirmed in a study published in the American Journal of Physiology. One group was fed a high-protein diet (just over 1 gram per pound of body weight per day) while the second group consumed an amount closer to the lower recommendation of the RDA (recommended dietary allowance). The group eating the higher-protein diet burned the most fat.
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."
