ketogenic diet: benefits and harms

Many of us are looking for a regimen to lose weight safely and without any risks.
Recently a weight loss regimen called keto was developed.
Given that little is known about this new system, there are many questions that arise, such as how does the ketogenic system work, how it takes your body to ketosis, and is there any harm to this system?
The ketogenic diet can be described as one that relies on consuming fats as an energy source and minimizing the use of carbohydrates.
This results in burning body fat and thus safely losing excess weight,
One of the main advantages of the keto diet is that it helps maintain muscle mass and is also great for diabetics.
Despite these advantages of the ketogenic diet, you should not follow this diet for a long time, in order to avoid some diseases such as osteoporosis.

Thank you!

I've heard that it is effective in weight loss, but there are also side effects when you do it for a long time.
