Summary

how to handle extreme nausea and near-zero appetite on retatrutide while still losing weight

The original poster started retatrutide at 2 mg every 5 days and quickly dropped to roughly 500 kcal daily with strong food aversion and vomiting. Several responders advised lowering the dose or stretching the interval because the jump was too aggressive for a first-time user. After returning to 1.5 mg every 6 days the nausea eased enough to allow some protein intake again, and weight fell from 78 kg to 69.2 kg in 24 days. The group generally agrees that sensitive responders should titrate more slowly and stay at each dose for several weeks.

What this discussion establishesWhere people disagree

whether to drop the dose immediately, wait for adaptation, or simply extend the injection interval

Still open

how long the food aversion may last and whether very low intake is sustainable without further intervention

Nothing here is advice.

I never expected to complain about this, especially with my history of food addiction and binge eating, but by week 4 I can barely smell food without feeling sick. Food used to occupy my mind constantly, yet now on 2 mg (started February 4th) even the thought of it turns my stomach. We tried Greek food yesterday and after a little meat and tzatziki I threw everything up. Right now the only tolerable options are plain rice cakes and other bland foods, so my protein intake has tanked and even meat, which I used to love, now repels me. Before starting I averaged around 2000 kcal; the first two weeks on reta brought that down to 1400, and lately I’m lucky to reach 500. I must be a very strong responder. Our scale needs batteries so I haven’t weighed in, but I began at 78 kg and my face looks thinner, collarbones stand out, and I can feel my ribs easily. Normally that would make me happy, but

you went too hard, too fast. Dial it down a bit—even dosing every 7 days would be fine, but every 5 days right at the start is too much. Drink some protein shakes so you’re at least getting something in and make sure you stay hydrated.

Makes sense, yeah. I figured maybe my body just needed time to adjust and I should push through. Drinking is tough too; even sipping water throughout the day leaves me feeling awful. I’ll probably wait a full 7 days and then drop back to 1.5 mg.

Effects hit their maximum after a month so I kept the level unchanged throughout that period prior to any increase. I used one milligram over those four weeks then checked if more was required since that quantity proved adequate 😊

Maybe go down to 0.5 mg every 3 days. That will let it build more gradually in your system and each shot won’t create such a sharp spike.

I think my head was blowing this out of proportion too. I just stayed calm and let a few days pass, and everything settled into the updated routine.

I went through something similar and then it changed. I started back in Sep 2025 using 0.5 then 1.0 for about a month and so on. Eventually I started getting hungry again around day 7, so I split the dose with 1.5 on Mon and 2.0 on Thur. I don’t get the every-5-days approach. I would move to every 6 days or split accordingly.

2 mg every 5 days works out to roughly 2.8 mg per week. That’s still not a huge dose, but it’s a big jump from 1 mg every 6 days. Clearly you’re responding strongly. Is this your first GLP? Why did you shorten the interval and raise the amount? When I overshoot, appetite flattens too much and eating becomes a chore. The fix is simply to lower the dose. I haven’t run into actual food aversion.

Hm, maybe? It wouldn’t really make sense though. I dealt with food addiction for years and every diet was a struggle that eventually led to rebound. Hunger returned on day five again. I have friends who pin every 3 days, so switching to 5 days instead of 6 didn’t seem like a big change. I’ll probably just go back to 6 days. I saw people start at 2 mg so I thought it would be fine, but maybe being shorter plays a role too. This is my first GLP, and I’m also using GHK-CU. On 1 mg I still got hungry but felt full quickly, which made hitting protein easy. The downside was landing at 1400-1500 kcal daily with slower results. With PCOS and being short it’s hard to lose without a big deficit. If protein weren’t an issue I’d probably just push through.

So is the goal to never feel hungry again? I still get hunger on 7-8 mg of reta once per week and I’m still losing weight.

LevelThistle44archiveFeb 22

I split doses starting in my third week on tirz because food noise returned. I switched to reta a couple weeks later and kept splitting. Injecting the same two days each week is easier to schedule than rolling days.

No, haha. The goal is to stop food from affecting how I feel or occupying my thoughts all day. That part is working.

PlainAlder11archiveFeb 22

I started at 2 mg for 4 weeks and even after the first shot both my wife and I noticed appetite suppression, though not extreme. The next rounds were 4 mg, and after the third one it hit harder. I think I was drinking too much water and felt full without wanting dinner. I cut back on water today to see how it goes. Beer also fills me up faster than before. You really want to stay on one dose for 4 weeks before increasing.

WryBramble37archiveFeb 23

I would stick with a simple weekly schedule. Don’t change the dose until after 4 weeks. It looks like you could have stayed lower if you had waited. Reset to your original weekly amount for 4 weeks and go from there. Keep it simple.

If side effects appear, wait until they fade before the next dose. It’s that straightforward, even if it means waiting two weeks for levels to drop. Then use a plotter to see what blood levels corresponded with the bad symptoms and the recovery, so you know exactly which levels to target or avoid. Later you can nudge the dose up slowly if hunger returns, but sensitive users should increase in tiny steps like 10-20 % per week. If that feels too involved, just wait out the side effects, drop the dose, and titrate extra slowly. Peak effect hits about 24 hours after injecting and levels halve after roughly a week.

ClearWillow37archiveFeb 23

If the lower dose was already working, try dropping back to see if the nausea stops. I began at 2 mg per week with no nausea and no appetite, then after 6 weeks moved down to 1 mg per week. It’s still effective—I’m losing weight and have little appetite, yet enough to manage one meat meal daily. Some of us are hyper-responders, which is great for cost.

SlowSignal13archiveFeb 27

Little update: I went back to 1.5 mg every 6 days. Nausea has mostly disappeared, though eating is still difficult and foods I liked now taste bland. I feel okay otherwise except still struggling to drink enough, but at least I can force down some protein again. I finally weighed myself and hit 69.2 kg today—almost 10 kg down in 24 days.
