It is my belief that sometimes (certainly not all the time) when people have difficulty bringing their weight down to something they feel comfortable with, it's because of Bovine Growth Hormone and other hormones found in meat, dairy products, and eggs.

A few years ago I was finding it to be impossible to get down to the weight at which I feel the most comfortable. I eliminated these hormones from my diet as much as possible, and I lost the weight quite easily after that.

I know this is difficult to do, but in my case it involved eating only organic dairy products and eggs. I haven't eaten meat in decades, so that wasn't an issue for me. But it is possible in some places, to obtain organically grown meat that doesn't have these hormones in it. It looks to me like you are in a country other than the US, and I don't know what the situation is where you are with regard to organic food products. But it might be worth looking into if you're in a position to do so, and if you're interested in finding out if it will help.
