Have you got some kind of reference for this, somewhere on the web?
I’ve taken care of patients that were 600+ pounds, and in the hospital they lost weight on 1800 cal diets. Of course, physical therapy took place twice a day, consisting of activities such as getting up into a chair, rolling over in bed, passive/active movement of legs. Most of the patients hated p.t. with a passion.
To make a statement like, “You are dead wrong” just seems to me to be rather extreme, and I’d like to have some sound theory/research to back that up.
I am betting you are not fat.
By the way, how many of these patients maintained their weight loss 10 later?
Please read post #43.
Count carbs not calories. If you are restricting your 600lb patients to 1800 calories like you say, how do you know if they are getting enough carbs if the diet isn't carefully calculated to ensure they do?
If they aren't getting enough carbs, they won't loose weight even if you cut "calories" to 1000. Calories can be anything. pure fat if you like.
If they don't get enough carbs, their livers will just make sugar from protein.
When the liver makes sugar, it always makes more than the body needs. The extra insulin this triggers the pancreas to make, stores this extra sugar as fat.
Then, next time their sugar gets too low (from a diet too low in carbs lets say) this again triggers the liver to make sugar from protein, which is always too much, and again the pancreas makes more insulin to compensate, storing the excess sugar as fat.
The fat keeps building up, even on a 1000 calorie diet.
