People who blame their weight on a disease are super human, iin?

I agree with you to a certain extent, because, in essence, weight loss is a simple math problem. More calories out than calories in. People who say it's impossible due to metabolic disorders are lying to themselves or miscalculating their caloric intake.

Having said that, you obviously have no compassion for people in that situation. There are health problems that significantly lower your basal metabolic rate. If you had to drop your calorie intake by, say 250-500 calories a day, you would definitely feel deprived unless you carefully managed your diet. Imagine having to feel deprived just to maintain your weight; I doubt you would be able to add enough of a caloric deficit on top of that to lose weight without feeling malnourished or lethargic. Now imagine having to feel deprived PERMANENTLY, as in being on a permanent diet without ever having a single meal where you could overeat, or a single day where you could indulge in unhealthy foods, because every single time you did that it would slowly add to your already existent weight problem.

I eat healthy. I love healthy foods. I love exercise, but I could never do that. Fuck that. If I had a metabolic disorder, I reckon I'd still be as healthy as possible, but probably overweight because I enjoy balance in my diet, which includes moderate and occasional amounts of unhealthy foods.

Have some compassion. Metabolic disorders are often used as an excuse, but they are real, and they do happen.
