Obesity is a chronic disease that can have negative effects on many body systems. In fact, people who are overweight can have serious health issues and develop a greater risk of developing serious conditions such as heart disease, type 2 diabetes and bone and joint disease.

We can combat obesity by making positive life changes and going on a life-changing diet such as the keto diet. According to the Body Reboot book, the keto diet can help you lose weight by switching to a high fat and protein diet and eating fewer carbs. Eating too many carbohydrates contributes to obesity, but luckily there's a way to combat that.

Summary
Background
Overweight and obesity are increasing worldwide. To help assess their relevance to mortality in different populations we conducted individual-participant data meta-analyses of prospective studies of body-mass index (BMI), limiting confounding and reverse causality by restricting analyses to never-smokers and excluding pre-existing disease and the first 5 years of follow-up.

Methods
Of 10 625 411 participants in Asia, Australia and New Zealand, Europe, and North America from 239 prospective studies (median follow-up 13·7 years, IQR 11·4–14·7), 3 951 455 people in 189 studies were never-smokers without chronic diseases at recruitment who survived 5 years, of whom 385 879 died. The primary analyses are of these deaths, and study, age, and sex adjusted hazard ratios (HRs), relative to BMI 22·5–<25·0 kg/m2.

Interpretation
The associations of both overweight and obesity with higher all-cause mortality were broadly consistent in four continents. This finding supports strategies to combat the entire spectrum of excess adiposity in many populations.

The U.S. Surgeon General has declared that obesity has reached an all-time high and that the results of being inactive and eating the wrong foods can cause a serious threat to one's health. It can even cause death, as the shocking study above revealed. That's why it's so important to get and stay healthy and you can do that by going on a diet such as the keto diet.
