Beyond stomach side effects, many people notice a much smaller appetite, new aversions to rich or greasy food, lower energy in the early weeks and mild redness where they inject. Eating smaller protein-forward meals on a schedule, drinking enough fluids, rotating injection sites and keeping your care team in the loop make these easier to manage.
- Eat on a schedule, even when hunger fades.
- Lead every meal with protein.
- Drink fluids throughout the day.
- Tell your care team about lasting fatigue or hair shedding.
What everyday changes are normal?
| What you notice | Everyday tip |
|---|---|
| A much smaller appetite | Eat small meals on a schedule and lead with protein |
| Aversion to greasy or rich food | Choose simpler, lighter meals |
| Feeling full fast | Eat slowly and stop at the first sign of fullness |
| Lower energy | Do not undereat. Get enough protein and sleep. |
| Redness at the injection site | Rotate between stomach, thigh and upper arm |
| Less interest in alcohol | Drink less, and not on an empty stomach |
How much should you eat?
Even with a small appetite, your body needs fuel. Build each meal around protein like lean meat, fish, eggs, Greek yogurt or beans, then add vegetables, fruit and whole grains. Eating too little can leave you tired and cost you muscle.
Is hair shedding normal?
Some people notice extra shedding a few months into weight loss, which is common with any fast weight loss. It is often temporary. Tell your care team, and focus on getting enough protein and calories.
When should you check in?
Reach out if fatigue lasts, if you cannot eat enough, or if anything feels off. Unlimited physician support is included in every plan.

Why don’t I feel hungry?
The medication is working on your appetite signals. Eat on a schedule anyway so you get enough nutrition.
Can I exercise on a GLP-1?
Yes. Walking and strength training are great choices. Eat and hydrate first.
Where do I inject?
Your stomach, thigh or upper arm. Rotate sites each week.
What if I feel tired all the time?
Tell your care team. Low energy often comes from eating too little, and they can help you adjust.
