How diet and exercise affect our risk of broken bones

Exercise and exercise are actually beneficial for the body and mind, but a combination of a low-calorie diet and exercise or exercise can damage the bones. This increases the risk of injury or breakage.

A recent study by the University of North Carolina School of Medicine found that a combination of calorie restriction and exercise can damage bones. The results of the study were published in the English-language journal "Journal of Bone and Mineral Research".

Diet plays an important role in our bone health

Previous studies on mice have already shown that exercise coupled with normal calorie intake and even a high-calorie diet is good for bone health. But apparently this does not apply to exercise together with a calorie-restricted diet.

How do diet and exercise affect bone marrow fat?

For the current study, the researchers analyzed the presence of fat in the bone marrow of mice. Previous research suggested that such fat could weaken the bones in mammals, including humans. The team found that reducing the average calorie intake in mice by 30 percent not only helped the animals lose weight, but also increased their bone marrow fat. The researchers further reduced calorie intake through exercise. They found that increased physical activity, while reducing bone marrow fat, also made bones more fragile.

Especially at an advanced age, we should pay attention to our bone health

Even a low-calorie and very healthy diet can have negative effects on bone health, especially when combined with exercise, the researchers report. Especially at an advanced age, bone health begins to decrease naturally. Calorie intake along with exercise and exercise can have a major impact on bone strength and risk of fractures.

Further research is already planned

The research group plans to continue the study to better understand how bone marrow fat affects the body. They also aim to examine the direct relationship between calorie restriction and exercise. (as)
