Does temperature affect fat burning? Does sweating increase weight loss?

According to popular belief, wearing warmer clothes promote fat loss (which is not true). But does training in different weather conditions actually give different results?

Sweating causes a temporary loss of water, not fat stored in the body. Weight loss does not always mean the loss of adipose tissue.

Scientists checked how obese men respond to training in cold and warmth.

Men exercised 2.5 hours a day for a week, alternating between climbing a step for 10 minutes and walking on a treadmill (5 km/h) for 10 minutes. One week they trained in warm temperature (approx. 25 Celsius degrees) and the next in cold temperature (approx. 10 Celsius degrees). Later the groups were changed places. Subjects had a negative energy balance throughout the study and therefore lost weight.

Training in cold gave slightly better results, but taking into account the combined results in both groups, it was not really spectacular.

Apparently, the difference was 46%, but in fact, 0.54 kg of fat was lost in warmer temperature and in the other – cold one – 0.79 kg

Bear in mind

Training in the cold temperature gives greater effects, but the most important thing to reduce fat is maintaining a negative energy balance. The most important thing to remember is that the entire 2.5 hours of low-intensity training meant an expense of 660 kcal in obese men. So the entire reduction can be wiped out by visiting McDonald’s or eating two regular doughnuts.
