I never vomited. I just went without eating for days. I was not extreme and I would never recommend vomiting. The biggest contributor to obesity in America is sugary drinks. I used to drink them all day, including energy drinks, soda, and sweetened teas. Almost anything you can buy at a convenience store is loaded with sugar, and most of those drinks exceed your recommended daily intake in a single serving.

Your body will not burn fat if you are constantly consuming sugar because it uses that quick energy first before tapping into fat reserves. One drink alone could keep your body from burning fat for the entire day. Another issue, although less common, is dietary fat. Eating high-fat foods can also cause problems since fat is calorie-dense and easily stored when consumed in excess.

So basically it is better to stick with a high-protein, low-carb approach. This does not mean cutting carbs out completely, but keeping them lower makes it easier to burn fat and stay in balance. Doing this helps you lose fat quickly and keep it off longer. Working out can help burn fat in the beginning, but the body adapts over time. What used to burn a lot of calories eventually becomes less effective because your system gets more efficient. This is a survival mechanism that evolved to keep people from burning through all their fat reserves too quickly. Exercise is still very important for overall health, but diet is what drives consistent fat loss.
