At 135 your BMI sits around 23 which is already in a solid range. Bodies often defend a certain weight and while these meds can shift a high set point they cannot keep lowering it forever.
Started on these meds back in 2022 with semaglutide from a doctor and dropped 50 pounds over the first year and a half. Insurance dropped coverage so I moved to compounded versions and switched to tirzepatide hoping for better results on the last 10 pounds. It took another year to go from 135 down to 125 at 5'4". Hit the top dose of 15 mg but side effects were rough so I dropped to 10 mg and started gaining. By April the scale was back at 130 and kept climbing with life stress and more hunger until I hit 135 again. Switched to reta seven weeks ago beginning at 2 mg for two weeks, then 4 mg for three weeks, 6 mg for two weeks, and now 7 mg this week. No scale movement despite walking, weights, yoga and other cardio. Reta seems to increase hunger for me at times but I have my food intake under control.
