This is true, but fat people have a hell of a time cutting out all carbs. For many of them, they'll eat the "low carb" option, and then have an occasional binge and it negates any benifits of low carb, and doesn't put them in ketosis, etc.

I strictly maintain my weight. If I catch it going over over 155# (I'm a 5'10" 61 year3 old male) I'll do a strict cut. And I know that either strictly counting calores OR going to as close to zero carbs will have the same net effect.

But a person who has obesity or is overweight will not be able to follow a diet. They are just incapable of doing so, or will lie to themselves or others about it and claim it's their "metabolism" or a medical condition, etc.

I’m 1.78m, 50 years old, my initial weight 2 month ago before I started the keto diet was 154kg and two months later I’m almost 130kg. Eating the same amount of calories as before.

This is an extremely unhealthy rate of weight loss. All guidance centers around .5-1kg/week as both safe and sustainable.

[arijo]

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

[claudenm]

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

[arijo]

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.

[fortran77]

Yes. But a real keto diet, where you are in ketosis, is impossible for most fat people to follow. They will inevitably cheat (“tee hee hee! It doesn’t count if it’s birthday cake! I’m so naughty”) and be in ketosis.

I’m fat, I’ve been cooking my own keto meals for more than two months, I’ve consistently been in ketosis and yesterday was my 50th birthday :)
