Is my appetite suppression too strong on a GLP-1?
TL;DR. Probably yes, if you're regularly eating under your minimum calorie floor (roughly your body weight in kg × 22 for a sedentary day, more if active) and feeling fatigue, headaches, or hair loss beyond week 4. Appetite suppression is the intended effect — but a suppression that drives you below maintenance-minus-500 isn't sustainable weight loss; it's underfeeding, and your body will respond by slowing metabolism and burning muscle.
What the cohort actually reports
Pattern 1: The "too strong" complaint is common and clusters around dose-up. In 38 r/Wegovy posts, users described appetite suppression so complete they struggled to reach 1,200 calories per day. The spike consistently followed a step-up from 0.25 → 0.5 mg or 0.5 → 1.0 mg. One user on 0.25 mg for 8 weeks was still unable to hit adequate intake; another described 17 days of vomiting after going to 0.5 mg.
Pattern 2: Many users conflate "successful suppression" with "healthy eating." The repeated framing in the corpus is "I'm doing so well — I'm barely eating!" Users who later developed fatigue, mood crashes, or stalled weight loss often retrospectively connected those symptoms to weeks of <1,200 calorie days.
Pattern 3: A small but real subset has prior eating-disorder history. A meaningful minority of "too strong" posts mention anorexia or restrictive-eating history. For this group, the drug doesn't just suppress appetite — it removes the cue that normally interrupts restriction. This is a specific risk pattern, not a generic warning.
What we'd add
The right frame is not "am I eating enough to lose weight" — it's "am I eating enough that my body doesn't fight back." Three checkpoints we'd watch:
- Calorie floor. Roughly body weight (kg) × 22 for a sedentary
baseline. Below that, expect the metabolism to adapt down within a few weeks. This isn't a precise number — it's a floor, not a target.
- Protein floor. ~0.8 g per pound of lean body mass per day. This
is the muscle-preservation number, and it's the one most cohort members miss because protein-rich foods often trigger the worst food aversion.
- The hair-loss signal. Hair shedding starting ~12 weeks after
consistent underfeeding is the body's late-warning system. By the time you notice it, the underfeeding has been going on for a while.
If you've been below the floor for >2 weeks and you're noticing fatigue, headaches, or mood crashes: don't try to white-knuckle through it. The two corpus-validated moves are (a) stay at your current dose longer before stepping up, and (b) build a small set of high-density foods that don't trigger aversion (Greek yogurt, eggs, smoothies have the strongest corpus support).
