Maintaining Weight Loss

[barry1010]

I am really struggling to maintain my weight loss and it is really getting me down. I've struggled with my weight since early childhood and I've probably lost and regained over 20 over the years. I've been to Weight Watchers and Slimers' World several times.

Six years ago I was diagnosed with Type 2 diabetes, eventually needing three different drugs every day. I got a grip and lost eight stone, reaching my target weight 2 years ago. I was able to control the diabetes by diet alone.
Over the past 6 months I have put on 12lbs and am now back on Metformin. I eat a very careful diet, 3 meals a day and absolutely no snacking or sugary products.
I can't think of any way to cut back my diet and am getting depressed and resentful.

Does anyone else struggle to maintain their weight loss? Any tips would be very welcome.
