Weight Isn't Everything These Keto 6x questions about health and effectiveness are often met with the assertion that fatness is fundamentally unhealthy, so everyone should try to lose weight. In fact, while there are several diseases and conditions associated with higher weight, they aren't necessarily a direct result of it. While fat people are much more likely to suffer from diabetes, high blood pressure and other metabolic problems, the correlation reduces significantly if those fat people are active and eat a good diet. Thin, sedentary people are actually at greater risk than people who are fat but otherwise in good physical condition. You may be fat and unhealthy, but your weight isn't the biggest factor. However, that doesn't mean that weight loss isn't effective.
