Hypothyroidism means that you take longer to burn energy. Therefore, over a 24 hour period you now burn less energy than before. eg before your BMR was 1500kcal and now it's 1200kcal. The problem these idiots have is that they still consume 1500kcal which over 24 hours is now a 300kcal excess. Yes, I have used normal human energy values as I have no idea ow much fat cunts really consume.
