Is The Ketogenic Diet An Ideal Diet?

I think keto diet works best for obese people as it helps to lose weight. For people with normal body type, this diet is good only in the short term. Its long-term effects are bad. This is my personal observation, but I would appreciate other perspectives.

I read some articles which say that not all nutritionists are supportive of the keto diet. They say that the weight lost during this diet is usually water weight. I haven’t tried it yet and therefore ain’t sure if it’s true. Would like to know from someone who has been following this diet.
