Why do people gain weight after middle age?
Obesity in middle age is a common phenomenon. After the age of 40, many people begin to gain weight uncontrollably. This phenomenon not only affects appearance, but may also cause a variety of health problems. So, why do people gain weight after middle age? This article will analyze metabolic changes, lifestyle, hormone levels, etc. from multiple perspectives, and combine it with hot topics and hot content in the past 10 days to reveal the truth about weight gain in middle age.
1. Decreased metabolic rate
As we age, the body's basal metabolic rate (BMR) will gradually decrease. This means that even if you maintain the same diet and exercise habits, your body will burn fewer calories, leading to fat accumulation. The following is a comparison of metabolic rates in different age groups:
| age group | Basal metabolic rate (kcal/day) |
|---|---|
| 20-30 years old | 1800-2200 |
| 30-40 years old | 1700-2000 |
| 40-50 years old | 1600-1900 |
| Over 50 years old | 1500-1800 |
As can be seen from the table, the basal metabolic rate drops significantly after the age of 40, which is one of the important reasons for obesity in middle age.
2. Reduction in muscle mass
As we age, muscle mass will gradually decrease, especially in people who are inactive. Muscle is the main tissue that consumes calories. Reducing muscle mass will lead to lower energy consumption and easier accumulation of fat. Here are the rates of muscle loss:
| age group | Muscle loss rate (per year) |
|---|---|
| 30-40 years old | 1%-2% |
| 40-50 years old | 3%-5% |
| Over 50 years old | 5%-8% |
It can be seen that muscle loss accelerates after the age of 40, and if strength training is not performed, weight can easily get out of control.
3. Changes in hormone levels
The influence of hormones on weight cannot be ignored, especially after middle age. The hormone levels of both men and women will change:
| gender | Hormone changes | Effect on body weight |
|---|---|---|
| male | Decreased testosterone levels | Muscle loss, fat accumulation |
| women | Fluctuations in estrogen levels | increased belly fat |
These hormonal changes make weight management more difficult after midlife.
4. Lifestyle changes
After middle age, many people’s lifestyles change, such as:
These factors can all contribute to weight gain. The following are popular discussions on social media in the past 10 days about weight gain in middle age:
