Why is it particularly easy to gain weight in winter? Science reveals the careful mechanism of the body

Every winter, the numbers on the weight scale skyrocket like they're on a rocket? Don't blame yourself for being lazy and gluttonous, it's actually your body causing trouble! Today we're going to uncover the body secrets that make you gain weight in winter.

1. The body's built-in "winter mode"

1. Metabolic automatic downshifting

Scientific research has found that the basal metabolic rate of the human body will actively decrease by 5% -8% in cold environments, just like turning on the "energy-saving mode".

2. Activation of Fat accumulation Program

Subcutaneous adipocytes increase in volume by 15% -20% in low-temperature environments, which is a survival instinct left by evolution.

2. Appetite Regulation System "Betrayal"

1. Increased secretion of ghrelin

Reduced sunlight can increase ghrelin levels by 25% -30%, making you feel like you're not eating enough.

2. Delayed satiety signal

In low-temperature environments, leptin sensitivity decreases, and the brain's reception of the "satiety" signal is delayed by 15-20 minutes.

3. Collective "Strike" of Fat Burning Mechanism

1. Decreased brown adipose tissue activity

Brown adipose tissue with fat burning effects has a decrease in activity of up to 40% in winter.

2. Discounted Energy Efficiency for Exercise

With the same amount of exercise, the amount of heat consumed in winter is 10% -15% less than in summer, just like exercising in power-saving mode.

4. "Invisible Assist" of Vitamin D

1. Sunshine Vitamin Deficiency

Vitamin D levels generally decrease by 30% -50% in winter, directly affecting fat breakdown metabolism.

2. Emotional overeating

insufficient vitamin D can also lead to a decrease in serotonin secretion, triggering emotional overeating.

5 tips to break the curse of winter weight gain:

• Eating enough 20 grams of protein for breakfast can reduce 10% of calorie intake throughout the day

• Sunbathing for 20 minutes from 3-4 pm can increase vitamin D levels

• Drinking 300ml of warm water before dinner can reduce 22% of food intake

• Doing HIIT exercises at home can increase fat burning efficiency by 30% compared to jogging

• Ensuring deep sleep can improve leptin sensitivity by 25%

Remember, gaining weight in winter is not your fault, but maintaining a good figure is definitely your ability! By understanding these "caution mechanisms" of the body and developing a scientific winter weight management plan, you can quietly lose weight while others are putting on autumn fat.
