Exercising at lower intensities will use more fat for energy. This basic premise is what started the theory of the fat burning zone, which is the idea that working in a certain heart rate zone (around 55 to 65 percent of your maximum heart rate) will allow your body to burn more fat. Over the years, this theory has become so ingrained in our exercise experience that we see it touted in books, charts, websites, magazines, and even on cardio machines at the gym.
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.
Running at an incline rather than on a flat surface has been shown to increase total calorie burn by as much as 50 percent, says Jill Penfold, a Los Angeles-based personal trainer. Whether you're outside on a hill or at the gym on an inclined treadmill, start out walking for five to 10 minutes, suggests Penfold. "Your heart rate should elevate pretty quickly as you pick up your pace," she says.
Eat more fat: The idea that eating fat makes you fat has been dethroned hard in recent years. And in fact, dietary fat can help you burn more off your body—as long as you’re eating the right kinds. Healthy polyunsaturated or monounsaturated fats—like salmon, trout, avocado, sunflower oils, olive oil, and nuts—can decrease appetite, improve heart health, and stabilize glucose levels which can help trim body fat, Montenegro explains.

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."
