This has been talked about a lot but I haven't found any explanation of where the excess weight "comes from", providing calories aren't increased? It goes against the basics of thermodynamics, doesn't it? I know that some weight is retained fluid but surely not all of it and not permanently! If you couldn't tell, I'm incredibly frustrated with my body for putting on weight, diagnosed 8 weeks ago and on 75mcg Levo currently. Last bloods showed ft4 and 3 in the lower range (which prompted an increase from 50mcg). I'm down to 2 work dresses to wear and don't want to leave the house because of how I look. I just want to cry.
