Not if you start from an extremely obese starting point like I did. I don’t recommend this rate to people with normal weight.

This is also wrong. It’s extremely unhealthy, unsafe and unsustainable to lose 15% of your body weight in 2 months.

Not wrong in my personal case - I've lost those 20+ kilograms with no problem to report.

Again, it was not a calorie restriction diet - it was a carb restriction diet.
