im 53 with limited mobility and im in a wheelchair and have tried losing weight for 2 yrs. i made basic changes, swapped sugar for sweetners, smaller plates etc. i gradually lost 1 st 2 lbs over 2 yrs. then 3 months ago i started on beta blockers and now the weight is creeping back on despite still eating the same as i did before. im getting quite dejected as i cant exercise to assist with weight loss. has anyone any suggestions.
