While I was on Zepbound, I stayed on weekly 2.5mg the whole 3 months I went from 202 to 170 (my goal). 13% body fat according to InBody at gym. I then went cold-turkey to reta at weekly 2mg and gained about 5 lbs in 2 weeks and upped it to 4mg after 4 weeks.
Appetite didn't change and I started losing weight agin. I'm definitely eating more after the switch but the reta doesn't seem to care. Something with the 4mg told my body to burn more and I do have more energy as well. I can barely keep up and may drop back down to 3 or 2mg weekly.
I was already on testosterone, CJC-1297/Ipamorelin, and GLOW during the whole Zepbound phase and still use these.
I eat one full meal a day that focuses on protein and veggies but there a carbs too...pasta, rice, whatever sugars are in the dishes. And I snack on things like meat sticks and protein shakes once or twice a day. Not the healthiest diet but it's not ben and jerry's every night.
I do play tennis 3-5 times a week and run/lift 3-5 times a week so I'm very active.
The only reason I went on this diet was because at 60 and being 200lbs, it affected my tennis mobility. Not to mention the 27% body fat and approaching insulin resistance pretty quickly.
