Twenty-five years old is a critical point for the human body, when physical strength and growth reach their peak. But after that, things gradually begin to decline. The earliest signs are that muscles begin to slowly lose strength and elasticity, then cardiopulmonary function begins to decline, and the body's basal metabolic rate also slows down slightly year by year. As a result, people's energy requirements from food, that is, the number of calories needed to maintain weight, also decrease.
Take action now.
The ratio of muscle mass to fat in the human body tends to decrease. For an average-sized woman, body fat accounts for about 26% at age 20, 33% at age 35, and as high as 42% at age 50. At the same time, bone growth stops, more bone tissue is lost and less is generated, and immunity begins to decline. The saying "Before age 30, people look for illness; after age 30, illness looks for people" stems from this very principle.
However, with early physical exercise and proper dietary habits, the aging process can be effectively inhibited and slowed down. The primary method for fighting disease is not various health supplements but physical exercise, and the primary method for fighting obesity is also not any of those but physical exercise.
No matter how old you are when you start exercising, the key is to start now and stick with it.
