If you agreed with his post, which is looks like you did, then you don't know what you're talking about either. Calories absolutely matter. Fat, protein, and carbs are just forms of energy. The shit is converted to fat when you don't use it. Basic science.

The forms of energy matter though. When your body is only burning fat -- it burns more calories. That isn't a normal state for most people so they are always or almost-always burning carbohydrate calories.
So essentially your body will be able to process 2600 calories like it was 1300 (just a guesstimate from a non-professional). Not to mention you would have a higher rate of static calories being burnt for the caloric deficit math.
I did lose like 50+ ;lbs on atkins eating lots of calories a day and not even exercising -- but I never got completely "thin" that way. But I'm sure if I restricted calories and stayed on it with exercise -- it would have worked. I've seen it work for others.
BTW: if he was 500 lbs and lost 90 -- its not really the same as if he was 270 and lost 90. Also -- we have no idea what his previous diet was like. Finally, you don't seem to acknowledge ketosis is a thing. It is.
