There is enough proven studies providing evidence of the benefit of ketogenic diet for obesity and overweight. In fact, it is shown to be more effective for weight loss than other low fat diets.
The ketogenic diet helps lose more weight in the first 3 to 6 months of following the diet than many of the other diets.
This is mainly because this diet uses fat to form ketones for energy instead of carbs which is generally used as a source of energy by the body. Since, changing fat into energy uses up more calories than changing carbs into energy.
Also, ketogenic diet is a high fat diet which is generally more filling and makes a person feel full for a longer time.
The process of ketosis that takes place in a ketogenic diet have appetite suppressing effects on the body which plays a major role in boosting the weight loss process in obese people.
In addition to weight loss, the ketogenic diet also helps in reducing triglycerides and increasing the HDL cholesterol levels in the body. This helps in preventing and treating the obesity related health problems.
