Try doing more exercise and cutting carbs count your calorie intake and take your Protein
I had my surgery March 2018 with the pandemic I lost track and gained 20 lbs was drinking too much eating things I’m not suppose to and pushing my eating limits, 2 month ago I decided it was enough bought I bike started doing exercise cut the carbs started counting calories I’m between 800 and 1200 per day, substituted dinner for Protein Shake and happy to say that after 2 months I’ve lost 25 pounds I’m doing around 120 to 150 miles a week on the bike I feel awesome and back on track I refuse to be part of the percentage that gains the weight
now I’m back to only eating 5 oz of food and feeling full before this reset I was eating 8-10 oz
