There are many ways to diet using various kinds of philosophies. One proven method is to do low carbohydrate dieting. One form of low-carb dieting is called the ketogenic diet.

This diet makes the body go into a state called ketosis. This state helps the body make sure it burns fat cells as carbohydrates are restricted so the body has to then turn to fat for its main source of energy. To ensure we can get to a ketogenic state, foods high in digestible carbohydrates should be replaced with foods low in carbohydrates.

As we limit the amount of carbohydrates, and thus the calories from them, we need to ensure we get enough calories from other sources, mainly protein and fat. One well-known diet, Atkins, relies on this methodology during its "induction phase." This induction phase makes the participant eat a very low amount of carbohydrates whilst eating a high amount of protein and a moderate level of fat.

An excellent low carb ketogenic diet is called this cyclical ketogenic diet. The diet breaks down the amount of protein, carbs, and fat into what is called macros. These macros help you distribute how much of each source of calories, so you eat the right amount for each meal. The best breakdown of calories from protein, carbs, and fat is a 65% fat, 30% protein, 5% carbohydrates ratio. The reason this diet is called a cyclical ketogenic diet is because we spend five days of the week doing a low carb phase and then the next two days is a high-carb, or carb-up, phase.
