That is so true, @rahul516. Especially if one is planning to keep it up long term, doing some research on how to keep good health while in keto is essential. For example, a keto diet can offset mineral and electrolyte balance in the body, which can result in anything from dizziness and cramps to increasing your risk of getting kidney stones. One needs to learn how to properly hydrate and supplement to keep such negative potential side effects at bay.
It is also true that many people get too confident and forget that if you want to see weight loss, you still need to create a caloric deficit; keto is not a magical pass to eat whatever without getting fat. Also, backsliding trying to see how many carbs you can reintroduce in your diet without falling out of keto is a very common "cheat" that stalls people's progress. I should know, I have made both these mistakes myself!
Totally agree with you.
