I've been on keto over the last 9 months, lost 8 kgs at height and recently gained 2 kgs back, so net about 6 kgs weight loss. TBH, I had to "cheat" on my keto diet in order to stop losing weight, because I feel like I was losing too much weight. My recent weight gain shows very little gain on the waistline, so I am going to assume the 2 kg weight gain is in the muscles

That said, keto may not work for everyone. It is very nuanced, and there is a lot of knowledge of your own body you need to understand. What is your BMI? How wide is your waistline? How much weight do you want to lose? What kind of keto food do you plan to eat? Are you going to incorporate intermittent fast? etc.

If you have more specific questions I will be happy to help, but at the end of the day keto is NOT about losing weight, but about being healthy by cutting carbohydrates and processed food from your diet. Once you do that, your weight will automatically come down.

Partially true. When you wake up, your body will go through what is called Dawn Phenomenon, where your blood glucose level is higher. Some people are able to take advantage of this and use up the blood glucose and it's easier to exercise in the morning because they're more energetic.

In terms of calorie consumption, it should be the same regardless of whether it is in the morning or evening, as long as you do it before a meal. I wouldn't worry about calories burned during workout, it's quite negligible in terms of your overall calorie consumption a day, unless you spend an ungodly amount of time exercising (more than 60 minutes).

Yes, but protein is simply a macronutrient. You need to think about the quality of protein you're getting as well. Also it depends what is your reason for eliminating meat.

This is a myth.

The human body does not use calories. You can be in a calorie deficit and NOT lose weight because your body is not getting the signal that is being properly fed.

Let me give you an analogy that most people can relate to:

When you earn less money, do you still spend the same amount?

The myth is that the human body burn calories. It doesn't.

If it does, please let me know which cell, or part of the cell, that uses it.
