A large-scale long-term study shows that obese middle-aged people have a lower risk of developing Alzheimer's disease. The researchers admit that they are surprised by these new findings because they are contrary to current health advice.

The team of Oxon Epidemiology Research Company and London School of Hygiene and Tropical Medicine analyzed more than 654.38+0.95 million people, with an average age of 55 years, and the research time was as long as 20 years. The most conservative analysis shows that underweight people have a 39% higher risk of developing Alzheimer's disease than people with healthy weight.

2. The risk of infertility will increase.

We all know that women need certain body fat to get pregnant. Women need at least 22% body fat for normal ovulation (normal adult women contain about 28% fat). However, what I want to say today is that being too thin will not only affect the fertility of women, but also affect the fertility of men. Men who are too thin are more likely to have erectile dysfunction and difficulty in ejaculation.

3. The mortality rate has increased.

A study published in the Journal of Clinical Endocrinology and Metabolism shows that among Japanese patients with type 2 diabetes, people with body mass index between 18.5 and 24.9 kg/m2 seem to have the lowest mortality rate, while the mortality rate of obese people has not decreased, while the mortality rate of BMIlt 18.5kg/m2 has increased.
