We have all heard about those fad diets like the grapefruit diet or the apple diet. I am here to tell you diets that work. All of those diets are fad, crash, "stupid" diets. A real diet contains a mix of muscle building protein, energy filling carbs, and healthy fats for your heart.
For losing weight, ketosis is the best diet and is not a fad. In a keto diet, one would eat lots of protein and fats and little carbohydrates to get there body in a state of ketosis. Since there is no more glycogen in your body, from the lack of carbohydrates, your body will build ketone bodies from your fat tissues to fuel your body and your brain. As long as you are eating enough protein, you will preserve your muscle and lose pounds of fat easy.
Getting into ketosis takes about 3-7 days depending on your current glycogen storage. Ketosis feels odd at first because you will be lethargic and may experience headaches and even nausea. However, these symptons go away. You will also drop lots of weight at first because of water weight.
Typical foods on a keto diet include nuts, whey protein, eggs, bacon, sausage, olive oil, butter, salmon, etc; anything that contains a high amount of protein and fats and no carbs. A vitamin pill is often taken in a keto diet since you can't eat much vegetables. (however you can eat at least one bowl of salad)
It takes strong willpower to stay on keto because if you cheat once or eat something bad your body will be out of ketosis. A process that took 3-7 days now has to be re-done.
In short, Keto is the best short-term diet you can do for cutting.
