It depends. It is eating very clean and actual food that is not processed or comes in a box if it makes sense. For example, increased amounts of vegetables, but not all vegetables are keto compatible. Maybe that can be a bit expensive some places.
But really it is quite simple and does not require any kind of supplements or special substitutes. It's meat, cheese, vegetables and nuts.
Maybe it is not always easiest for people to stick with, because carbs are delicious and there's also sugar with them. It is hard to let go of them. You need to discipline yourself.
Weight loss is one of the benefits of keto. Take a look at the "KetoSchool benefits of Keto" I linked in the post to see all the other good things keto does. I mean it really helps overall health and even nervous-system.
Oh thanks. I am pretty slim and actually need so flesh in certain places. I am not sure a keto based diet would be good for me.
You'll find that if you are under weight that it would bring you up in weight. It is good for establishing the best weight for your body without excessively adding more fat (in the form of triglycerides) to your body. This is because you are not eating carbohydrates that turn into directly into triglycerides, putting fat where you don't want it. i.e on your stomach and back. The main benefit of keto diets would be on your digestive systems and can solve a lot of ulcserative, heliobactor and acidity related issues.
