Navigating Your First Month on a GLP-1: What to Expect

Quick answer: In the first month, focus on smaller protein-forward meals, steady hydration, and giving your body time to adjust between dose increases. Nausea is most common right after a dose change and usually eases within days. Contact your provider rather than pushing through if side effects are severe or persistent.

Starting a GLP-1 medication like compounded semaglutide or tirzepatide is an exciting step toward achieving your weight loss goals. However, knowing what to expect during your first month can help you manage your journey more effectively and comfortably.

Here is a guide to navigating your first four weeks on a GLP-1 medication with Fig.

The Titration Process

GLP-1 medications are designed to be introduced to your body gradually. This process is called titration.

During your first month, you will start on the lowest possible dose. This allows your body to adjust to the medication and minimizes the risk of gastrointestinal side effects. It is important to understand that this starting dose is primarily for acclimation, not necessarily for massive weight loss.

Do not be discouraged if you do not see dramatic numbers on the scale in the first few weeks. The goal of the first month is to build tolerance.

Changes in Appetite

Even on the lowest dose, many patients notice a shift in their appetite within the first few days. You may find that you:

• Feel full after eating smaller portions.

• Have fewer cravings for sugary or high-fat foods.

• Think about food less frequently throughout the day (often referred to as a reduction in “food noise”).

This is the medication working to regulate your hunger signals.

Managing Potential Side Effects

Because GLP-1s slow down digestion, gastrointestinal side effects are common, especially when you first start or when you increase your dose. You may experience mild nausea, constipation, or an upset stomach.

To manage these side effects:

• Eat smaller, more frequent meals. Avoid large, heavy meals that sit in your stomach.

• Stay hydrated. Drink plenty of water throughout the day.

• Prioritize protein. Focus on lean proteins to help maintain muscle mass as you lose weight.

• Avoid greasy or highly processed foods. These can exacerbate nausea.

Frequently Asked Questions

What should I eat during my first month on a GLP-1?

Focus on smaller, protein-forward meals with plenty of fiber and vegetables. Heavy, greasy, or very large meals tend to sit poorly while your body adjusts. Eating slowly makes a real difference.

How do I manage nausea in the first few weeks?

Smaller meals, steady hydration, and blander foods usually help. Nausea is most common right after dose increases and typically eases within days. If it persists or is severe, contact your provider rather than pushing through.

How much water should I drink on a GLP-1 medication?

More than feels natural, because reduced appetite often reduces thirst cues too. Many providers suggest steadily sipping water throughout the day rather than relying on thirst. Ask your provider what target makes sense for you.

What should I do if side effects are too severe?

Contact a licensed provider promptly. Dose adjustments or a slower titration schedule resolve most issues. Fig patients can message their care team directly, and if you have not started yet, you can take the free assessment to get provider-guided treatment from day one, when prescribed by a licensed provider.
