Is it easy to lose weight in summer or in winter?

It is easy to lose weight in winter, and the basal metabolic rate in winter is higher than that in summer. Basal metabolic rate refers to the basic heat to maintain human function, which will be consumed by itself even if the body is still all day, accounting for 65~70% of the total heat consumption of human body.

Because human beings need to keep their body temperature around 36 degrees, in order to resist the low temperature, the human body will automatically adopt a mechanism to raise the body temperature, that is, to increase the basal metabolic rate, so compared with summer, it will consume more calories to supplement the heat. The basal metabolic rate in winter is even higher than that in summer 10%. In other words, the key to losing weight in winter is that the human body has the instinct to keep body temperature.

In addition, exercise can also improve the basal metabolic rate. The better the basal metabolic rate, the easier it is to consume calories and the less likely it is to gain weight. Winter is the best time to lose weight! Here are some reasons why you are thinner in winter.

1, basal metabolism increased.

When the body is in a relatively cold state, the body will increase basal metabolism in order to resist the cold, so the basal metabolism in winter is about 10% higher than that in summer, and the heat consumption is relatively greater.

And when the basal metabolism of the body increases below 15℃, the same amount of exercise can consume more calories. In other words, doing the same exercise in winter can burn more calories than in summer, and the lower the temperature, the better the weight loss effect.

2. Brown fat is active

Human body fat can be divided into three types: white, beige and brown. White fat is mainly responsible for storing calories and brown fat is responsible for consuming calories.

Studies have found that brown fat consumes five times as much energy and produces five times as much heat as muscle tissue. If the body contains 50 grams of brown fat, it can help the body consume 20% more basal metabolism every day, which is equivalent to running for an hour.

In a cold environment, the activity of brown fat will be higher. After 2 hours at19℃, brown fat can promote the burning of white fat and reduce the body fat content.

3. Fat energy supply

In different environments, the energy system used to regulate body temperature is different. In summer, the ambient temperature is high, so it is necessary to secrete sweat and increase heat dissipation in order to lower the body temperature. At this time, the energy supply mainly comes from sugar; When the temperature is low in winter, the body needs to raise its temperature, so it mainly relies on fat for energy supply.

Moreover, the synthetic speed of fat in winter is 2~4 times faster than usual, and fat is easier to accumulate. If you don't lose weight at this time, your weight may soar after winter and it will become more difficult to lose weight.

Summary: Increasing the basal metabolic rate in winter will make it easier for us to consume calories and fat, so we can make more use of the concept and opportunity of burning calories in winter > burning calories in summer, and seriously implement the weight loss plan, which will get twice the result with half the effort.
