I have always been a person who works out on a regular basis with strength training at least 3 times a week and some type of cardio activity at least 4-5 days a week . My diet has changed to mostly plants with a little fish, turkey , or chicken. I am over the age of 70 and am trying to lose at least 10-15 pounds. The struggle is real. The weight just does not want to come off. I have just have seemed to plateaued at this point. Any suggestions?
