Just by cutting my sugar and carb intake 2 years ago I lost 56 pounds.

Only one answer to that, eat less and move more.
There's no miracles.

Comfort foods are always high in myriad forms of sugar. Sugar in the absolute cause of packing on fat. Lots of books on the matter with my favorite being eat fat until your pants fall off. You should also be sure your thyroid level isn’t too low. Dr. should know. Good luck.

Exercise in whatever way you can, get advice from a physiotherapist, and eat sensibly...no faddy diet where the person writing the book makes a fortune.
