When the winter rainy season, people need more calories to maintain body warmth. The experts discovered the truth behind these fact, during the winter people tend to eat more and an average body weight increased 1-2 kg.

Consultant gastrointestinal surgeon at BUPA Cromwell Hospital, Ahmad said the composition of white fat that stores energy, brown fat to burn calories affect weight loss during the winter. “Those who are overweight actually feel cooler,” he said.

“This happens because you store excess calories in white adipose tissue, while the fat that makes you warm is brown adipose owned and infants are genetically inherited,” he said as quoted from the Daily Mail.

winter and famine
Historically, winter is associated with hunger, so the body storing fat reserves in winter to help survive.
“We now no longer need to store fat because food availability. So do not think eating too much,” said Ahmad.

He mentions, this is not a reason to become more obese over the winter. “You can control by choosing the right foods,” he said.

Hormonal
While Jeremy Tomlinson, an endocrinologist at the University of Birmingham said that during the winter rainy season, the body produces the hormone melatonin, which is generally triggered cloudy and dark atmosphere. These hormones that make us feel sleepy, also raise the appetite.

Professor Craig Jackson added, during the winter, people tend to feel more unhappy and bored quickly due to the dark, wet and cold. And, eating is one of the easiest ways to overcome boredom. “Consequently, we can take twice as much food. We are also more likely to eat sweet or fatty foods.”

Low levels of vitamin D
Other studies have shown low levels of vitamin D with the lack of sunlight can affect body weight in the winter.

“Your body needs sunlight to synthesize vitamin D, but in the rainy season and winter sunlight is more scarce and people are lazy to move out of the room or cover the body with coats and jackets,” said Dr. Stephanie Dillon, senior lecturer in Nutrition at the University of Central Lancashire.

Preliminary studies showed that people with low levels of vitamin D store more fat. “It seems that vitamin D deficiency triggers the storage of fat and calories in adipose (fat) cells rather than for energy,” said Dr. Dillon.
He was advised to eat fish and under the sun for 20 minutes every day.

Lack of movement
It was raining and cold means that there are many activities carried out. most people move in the home such as watching television and snack foods. “Being at home is often associated with feeding activity such as watching television,” said Professor Jackson.

Experts agree, in addition to choosing foods, stay active and exercise very important in maintaining fitness and health.
