The hotter your body gets, the more blood your heart needs to pump to expel that heat. Thus your heart works harder in hotter temperatures than it would in cooler temperatures, providing an increased calorie and fat burn.

Your body's internal clock plays a role not only when you're most alert and sleepy, but also when you burn the most calories, a new study finds. The study found that, at rest, people burn about 10 percent more calories in the late afternoon and early evening, compared with the early morning.

When you exercise, you use muscle. This helps build muscle mass, and muscle tissue burns more calories -- even when you're at rest -- than body fat. According to Wharton, 10 pounds of muscle would burn 50 calories in a day spent at rest, while 10 pounds of fat would burn 20 calories.

Your body works harder to stay warm by generating its own heat, and so, you end up burning calories without even trying to. It might not be visible enough, but you are more likely to naturally lose weight during winter.

The reason? It is because your body has to work harder to cool itself. The hotter your body gets, the more blood your heart needs to pump to expel that heat. Thus your heart works harder in hotter temperatures than it would in cooler temperatures, providing an increased calorie and fat burn.

To increase your base rate of calorie-burning, you can exercise or do activities like a sauna. The accepted rule for how many calories a person in a sauna will burn on average is 1.5 times more than base rate. The average person weighing 150 pounds and sitting for 30 minutes burns approximately 56 calories.

When you're active, your body draws on recently consumed calories for fuel, and only taps into its stored energy supply (fat) once the available calories have been depleted. In other words, the difference between burning calories and burning fat depends on the type of fuel your body is using.

In other words, heat in your system radiates out into cooler air. Radiation of heat causes re-routing of blood flow to the surface of the skin, which in turn makes your heart work harder by beating faster and pumping harder. On a very hot day your heart rate can quadruple compared to its rate on a normal day.

Sweating is the body's natural way of regulating body temperature. It does this by releasing water and salt, which evaporates to help cool you. Sweating itself doesn't burn a measurable amount of calories, but sweating out enough liquid will cause you to lose water weight.

The perception that we lose more weight when it's warm out may come from the fact that we sweat more when we're hot. But losing weight via sweat means losing water, not fat, says Walter R. Bixby, associate professor of exercise science at Elon University in North Carolina.

Does Drinking Cold Water Burn More Calories than Warm Water? Our bodies can burn calories in several ways: basal metabolic rate (BMR), physical activity and digestion. Drinking cold water rather than warm is not one of them. Or, at least cold water doesn't burn enough calories to be worthy of mentioning.

On a hot day, your cardiovascular system ramps up its efforts to radiate heat to cool you down. Your heart beats faster and pumps harder, and may circulate two to four times as much blood each minute as it does on a cool day. When temperatures soar, perspiring can put a strain on your cardiovascular system, too.

The body does use more energy to stay warm when it's cold out. ... Both shivering and brown fat activity increase your energy expenditure, causing you to burn more calories in cold temperatures.

Sweating itself doesn't burn a measurable amount of calories, but sweating out enough liquid will cause you to lose water weight. It's only a temporary loss, though.

Do we Burn more Calories in the Summer vs. Winter? Contrary to popular belief, our bodies burn slightly more calories adapting to cold temperatures than we do adapting to warm weather. When our bodies produce heat, we burn extra energy aka extra calories.
