So in October/November time I was told by the doctor to loose weight

[background story; I have been in Pain since April with my breasts (34JJ) and the doc suggested weight loss to help me be eligible for breast reduction]

So I started at 14st and now I am at

12st 5.2lbs but I not able to shift more weight I keep putting some back on and coming back to this weight. But I need to get as close to 11st as possible to be re-considered but with my chronic pain it is hard to do lots of exercise so I was wondering if anyone had any diet tips and tricks ☺️
