It may seem like a no-brainer that regular exercise can help you burn fat and lose weight. But it's not just about the calories you're burning. It's also about the adaptations your body makes when you exercise on a regular basis. Many of those adaptations lead directly to your ability to burn more fat without even trying. When you exercise regularly:

Get active in small ways. Even the slightest amount of activity is better than none at all. Studies show that fidgeters, on average, weigh less. Non-fidgeters are even more likely to store calories as fat. So in addition to cleaning the house, walking the dog, and parking on the far side of the parking lot, find time to fidget, if that's your kind of thing![21]
A big part of weight loss is simply being aware of the decisions you’re making. For example, when out at happy hour with friends, you may lose track of how much you're eating or drinking. But if you take a split second to step back and become aware of that fact, you’re more able to course correct. “The awareness and then planning for what else I can be doing, that might give me the same benefit of eating comfort foods,” says Gagliardi.
After the second month, Jill had lost a total of 31 lbs, while building her muscles by doing the exercise. She thus lost more weight in terms of fat than those 31 lbs, given she added some muscle mass. At this point, she has lost about half of what she needs to. It does not surprise me, given she no longer drinks any soda! For Mariah, the change was less dramatic, because she started with less weight to begin with. She has lost 19 lbs by now, slightly more than half of what she needs to. Interesting!
If you're not up for crunching numbers every day, you can take a more generalized approach. “For some people, it’s knowing, ‘Typically I eat a whole sandwich,’” says Gagliardi. “Now, I’m going to eat half a sandwich at lunch and save the other half for my dinner and cut my calories in half." To get started, consider these 25 ways to cut 500 calories a day.
Lose fat with high-intensity interval training (HIIT). If you're trying to lose weight fast, HIIT training can super-charge your metabolism for upwards of 24 hours after exercising.[27] This means your body will continue burning calories long after you've ended your workout. HIIT burns more calories in less time than steady-state cardio. In one study, researchers looked at two groups, one running for 30 to 60 minutes three times per week, the other doing four to six 30-second treadmill sprints, resting for four to six minutes between each sprint. After six weeks, it was found that the group doing HIIT training lost more weight.[28]
The researchers explain that people who cook their own meals may simply have other good-for-you habits, like exercising more. However, they also concluded that home cooks ate more fruits and vegetables (along with a wider variety of foods), have healthier methods of prepping their food, and splurge less on foods high in calories and sugar. Consider any of the healthy eating books below to get started.
1. Boost your metabolism throughout the day: Your BMR regulates how many calories you burn at rest and the more you move, the higher your BMR, and the more you’ll burn when standing still. Small efforts like taking the stairs, walking to pick up lunch, even playing pool with the guys during happy hour can all jumpstart your metabolism.

2. Eat smaller meals more frequently: “Insulin is probably the single most important factor that contributes to fat storage,” Seedman explains. This hormone is activated when you eat and responsible for shuttling nutrients into cells, either fat or muscle. A quick biology lesson: Every time you eat a meal, your blood glucose spikes, and when this goes up, so do your insulin levels. More calories at once means a larger spike in both. When these levels are sky high, it signals to your body to put nutrients into fat cells instead of muscle, causing an accumulation of fat, Seedman explains. The same thing happens when your insulin stays elevated for a prolonged period of time, which is why it’s important to let yourself become hungry before eating again, he adds. Aim for five to six meals throughout the day.
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.[12]
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.

Work your core. When many people think of core strengthening, they think of stomach crunches. Crunches are helpful for building abdominal muscles, but contrary to popular belief, crunches won't do much to lose the layer of fat stored in your belly, and can actually cause significant damage to the spine.[34] Instead, try a workout routine that strengthens your whole core, like yoga, or try abdominal presses and planking.[35]


Getting your Om on won’t burn as many calories as a hilly run or lifting weights, but it can help build muscle and improve your endurance, which are all crucial for boosting your metabolism. Some of the highest calorie-blasting yoga poses include plank, chair, Chaturanga, and wheel. New to yoga and aren't sure where to start?
