GLP-1 medications work in part by mimicking the effects of natural hormones that control hunger. One of the main goals of treatment is reduced appetite, which helps support weight loss. But how much appetite suppression is normal—and when should you be concerned?
What to Expect
Reduced hunger is expected and often noticeable within the first 1–2 weeks.
You may feel full with much smaller meals or have little to no desire to snack.
Many patients report they forget to eat or feel satisfied after a few bites—this is a common and intended effect.
Cravings, particularly for sugar or processed foods, often decrease significantly.
What’s Not Normal
While a lower appetite is the goal, extreme suppression that leads to undereating or malnourishment is not. Watch for:
Skipping multiple meals a day due to zero appetite.
Significant fatigue, light-headedness, or weakness.
Rapid weight loss exceeding 1.5 kg per week after the first few weeks.
Feeling unable to eat anything at all, even when trying.
Tips to Manage Healthy Intake
Focus on protein: Aim for protein with every meal, even if small.
Choose nutrient-dense foods: Include eggs, meat, Greek yoghurt, smoothies, and vegetables.
Eat on a schedule: Set reminders to eat, even if not hungry.
Hydrate: Sometimes low fluid intake can make appetite worse or cause fatigue.
When to Contact Your Doctor
If you can’t eat enough to feel well, experience signs of nutrient deficiency (e.g. hair thinning, dizziness, weakness), or lose too much weight too fast, message your doctor through the portal. We may adjust your dose or help with dietary strategies.
Appetite suppression is a helpful effect—but balance is key. Aim to fuel your body while taking advantage of the reduced hunger to build better long-term habits.
