Why does a healthy diet + exercise make the body more vulnerable?

A girl said to me: I have paid special attention to healthy living in the past two years

Many people have this experience: when they first started exercising, their body became lighter, their sleep quality improved, and they became more energetic during the day

Eat less and exercise more? Be careful not to keep up with nutrition

In most cases, it is because nutrition cannot keep up

Her weight is in the normal range, she doesn't need to lose weight at all, but she "eat less and exercise more" as an adult

There are also friends who use sports apps and pursue record-breaking every day

The World Health Organization recommends that ordinary healthy people exercise 150 minutes of moderate intensity a week

Of course, specific to each person, how long and how much intensity is the most suitable exercise, there are still big individual differences

Some particularly self-disciplined people, obviously staying up late to work and exhausted, have to complete their training plans in the gym

Hungry high-intensity exercise does not reduce the risk of cancer

Many people may think that exercise will at least help improve blood sugar control, the higher the intensity, the better the effect

The results showed that the indicators improved in the first and second weeks; however, the indicators deteriorated in the third week.

In other words, excessive exercise not only cannot improve blood sugar, it can even impair blood sugar control

There are also research data showing that although eating more and not exercising is not conducive to cancer prevention, eating less and adding high-intensity exercise, compared with eating an appropriate amount and high-intensity exercise, does not reduce the risk of cancer, but slightly increases

If necessary, you should go to the "Sports Nutrition Clinic" of the hospital for treatment

Similarly, we can understand that it is the same for people who lose weight

Therefore, the exercise must pay attention to gradual progress and flexible adjustments
