Why is it harder to lose weight in winter? 4 reasons that make you suddenly realize

When winter comes, with a down jacket wrapped around it, a weight scale becomes the least popular household appliance. Mingming ate like Xia The sky is almost the same, but my waist has quietly expanded a circle, even my jeans are silently protesting. This is not an illusion, the body does activate a "survival mode" in low temperature environments, making fat particularly attached to home.

1. The body activates the automatic warming program

1. Changes in basal metabolic rate

When the temperature drops below 15 ℃, the human body consumes more energy to maintain body temperature. But don't get too excited too soon, this kind of expenditure is far inferior to the "energy-saving measures" initiated by the body - muscle tremors reduce heat production, some organs have lower metabolic rates, and overall energy expenditure may be lower than that of spring and autumn Seasonal decrease of 5% -8%.

2. Decreased brown fat activity

Brown adipose tissue that can burn white fat will gradually become fatigued in sustained cold environments. Just like a workaholic who works overtime for a long time, continuous low-temperature stimulation can slow down the response of this "good fat" and greatly reduce the efficiency of fat burning.

2. Disruption of appetite management system

1. Elevated levels of ghrelin

Shortened light exposure time can affect hypothalamic function and promote the secretion of more ghrelin in the stomach. This hormone is like a 24-hour food delivery app, constantly reminding the brain to order high calorie charcoal grilled pork belly.

2. Decreased serotonin secretion

insufficient sunlight exposure leads to a decrease in serotonin levels, and the brain instinctively seeks foods that quickly enhance pleasure. The allure of hot chocolate paired with cream toppers tripled on a chilly afternoon.

3. Cliff like decline in exercise willingness

1. The influence of low temperature environment

Outdoor running has become an extreme sport to fight against cold winds, and the journey to the gym is as far away as learning from the West. 99% of people will reconsider their exercise plan when their fingers touch the cold door handle.

2. The illusion brought by clothing

Thick clothing is like a natural photo editing software, removing all body defects. Looking at the relatively symmetrical contours in the mirror, moving inside The clothes let out a lonely sigh in the drawer.

4. Changes in water metabolism rhythm

1. Delayed thirst sensing

Cold can inhibit the activity of the thirst center, and the dehydration signals emitted by the body are often misinterpreted as hunger. Many people hold thermos cups and drink hot water, which may not be summer yet Drink a lot of iced milk tea during the day.

2. Invisible dehydration phenomenon

In a dry heated room, the rate of water evaporation through respiration and skin is accelerated. Mild dehydration can affect the efficiency of the liver in breaking down fat, causing the weight loss process to lag like frozen gears.

Fighting against winter weight gain doesn't require extreme dieting. Try increasing your breakfast protein ratio by 20%, using small dumbbells instead of sofa potato time, and doing group stretches every two hours in the office. Remember, Spring Before the arrival of heaven, you were just engaged in a smart guerrilla battle against biological instincts.
