Hey Eddie... I know how you feel, I too am the same size as you. I got so desperate that I decided to go for gastric surgery.
I was told that the gastric sleeve was what I needed, but that was only because it was the quickest and easiest for the surgeon to do. I wish I had never bothered because I am still the same size.
I eat healthy foods and it still won't move. However, back when I first had surgery in 1986, I did used to do a lot of exercise that did help. Now I have a degenerative spine, walking is difficult, so the weight went back on.
I wish I had never stopped exercising but moved house with less space to do it, and changed jobs so worked longer hours. But these seem like excuses now, maybe I was just lazy and didn't look after myself properly.
I do aquafit classes now 3 times a week. I haven't lost any weight, but definitely fitter. But still can't walk far. Wish you luck with your quest. M
