Why is it harder to lose weight in winter? 6 reasons revealed, most people are stuck in the third one

When winter arrives, the numbers on the weight scale seem like they have been enchanted, even though they haven't eaten much, their pants quietly tighten. Don't blame yourself for weak willpower, it may be your body playing a 'winter survival game' with you.

1. The body automatically turns on "energy-saving mode"

1. Decreased basal metabolic rate

In cold environments, the human body instinctively reduces energy consumption, just like a phone turning on power-saving mode. Research has found that basal metabolism in winter may be higher than in summer Seasonal decrease of 5% -10% is equivalent to consuming half a bowl of rice less calories per day.

2. Decreased activity of brown fat

Brown fat that can burn calories should be more active in cold weather, but modern people are in a constant temperature environment for a long time, and this natural "fat burner" has instead entered a dormant state.

2. Disruption of appetite regulation system

1. Fluctuations in serotonin levels

Reduced sunlight affects the secretion of pleasure substances in the brain, and the body compensates by consuming high carbon water foods. That's why in winter, people always want to hold hot milk tea and carbohydrates for frying I won't play.

2. Increased secretion of ghrelin

Cold stimulates the stomach to produce more ghrelin, which makes you feel like you can eat another cow two hours after a meal, especially with a preference for high-fat foods.

3. Cliff like decline in exercise willingness

1. Decrease in outdoor activities

On cold mornings, the distance between bed and gym is always as far as Siberia. The data shows that the average winter exercise duration has decreased by 40%.

2. Discounted Exercise Consumption

With the same amount of exercise, the amount of heat consumed in a low-temperature environment is 15% less than at room temperature, as the body prioritizes maintaining core temperature and reduces energy output from limbs.

4. Vitamin D inventory is in short supply

1. Insufficient exposure to sunlight

Exposure to sunlight through glass can only provide psychological comfort, as the ultraviolet B band cannot penetrate glass to synthesize vitamin D. When this sunlight vitamin is insufficient, the rate of fat breakdown will significantly slow down.

2. Limited food sources

There are not many natural foods containing vitamin D, and a single winter diet structure is more likely to be lacking. It is recommended to eat deep-sea fish 2-3 times a week, but do not rely on eating mushrooms to make up for daily needs.

5. Severe lack of water intake

1. Delayed thirst sensation

Low temperature reduces the body's sensitivity to dehydration, and sometimes what you think of as hunger is actually a sign of dehydration. Try drinking a glass of warm water before meals, which may instantly dispel the idea of adding meals.

2. accumulation of metabolic waste

When water is insufficient, the liver will prioritize processing toxins rather than breaking down fat. Observing the color of urine, a light lemon water color is the ideal state, don't wait until you are thirsty to drink water.

6. Collective decline in sleep quality

1. Melatonin secretion disorder

Short days and long nights in winter disrupt the biological clock, and reduced deep sleep can affect leptin secretion. Stay away from electronic devices one hour before bedtime and try using a warm light desk lamp to create a sleeping atmosphere.

2. Bedding temperature trap

An overheated environment actually reduces sleep quality, with 18-22 ℃ being the most suitable for fat burning. Don't wrap yourself in Zongzi, which is light and breathable Clothing is more conducive to health.

Fighting against winter weight gain does not require extreme dieting. Starting with adjusting the indoor temperature, lowering the heating by 2 ℃ will burn 5% more calories in the body. Prepare some nuts that need to be peeled off as snacks, which can prolong eating time and supplement healthy fat. Remember, Spring Before the arrival of heaven, what your body needs is not a rigorous weight loss plan, but a smart winter survival strategy.
