People today are in to the Keto diet since this is another way of losing fat quickly and efficiently. In this method, you actually lose weight when the body uses the stored fats in it to give it energy, instead of using carbohydrates as its energy source. When body fats are burned so that the body will have energy, sooner or later, your body fats will get lower and you will begin to lose weight.
If a person want to start a ketogenic diet, he must eat high fat diet and low protein with practically no carbohydrates or a very sparse amount. The proper ratio for this fat to protein diet for the first two days is 80:20. This ratio should be followed strictly in the first two days since this will bring your body into the ketogenic state. After this stage, you need to slowly reduce your fat intake and increase your protein intake, and you can slowly add carbohydrates too. In order for the muscle tissues to grow and be sustained, you need to increase your protein intake. Carbohydrates should still be at a minimum so you can go a ratio of 65:35:5 fat-protein-carb ratio. The reason why carbs are kept at a minimum because it is the one responsible for triggering the pancreas to release insulin which is responsible for storing calories as fat. The absence of calories will not release insulin to store fats.
Since the body needs an energy source which we usually get from carbohydrates, its absence means that the body has to look for another source. And since fat is stored in our bodies, this will be the natural alternative to give the body energy for its needs instead of carbs. When your body is using stored fat to give fuel to the body then this is called ketosis. In this state body fat is lost since the body uses it for energy and your muscles are still maintained because of the presence of protein in your diet.
If you are able to sustain the fats-protein-carbohydrate ratio then you will be able to maintain the state of ketosis and be successful in your weight loss program. Eating fats to give your body energy is the rule of this diet, and when there is no longer energy to sustain it, it will start using the stored up fats in your body. The good thing about this diet is that you always feel full since fats take time to digest.
It will be alright to do the keto diet all through the week and during weekends you can have a carbs up day. It is important that some days you take carbs since this will also allow the body to take in other important nutrients that the body needs for growth.
