Feeling exhausted?

You may have wanted to lose weight so you could have more energy to do the things you love. But instead, you have found yourself exhausted, sometimes barely able to get out of bed. This was NOT what you were expecting!

Unfortunately, this is common, especially in the early weeks. It’s not the medication itself, but what changes around it.

When you’re eating less, drinking less, or unintentionally under-fueling, fatigue is often the first signal your body sends.

Here’s how to approach it in a way that actually supports your weight loss instead of working against it.

1. Hydration matters more than you think

GLP-1 medications can reduce thirst and increase nausea, which means many people are drinking far less than they realize. Even mild dehydration can show up as fatigue, brain fog, and headaches.

Aim for at least half your body weight in ounces of fluid per day.
If plain water is hard to tolerate, flavored water, electrolytes, or herbal teas can help. I always carry this water cup with me (and aim to drink 3+ per day) and use LiquidIV (my favorite electrolytes) if I am feeling dehydrated.

2. Eating too little will backfire

This is a big one. Let’s say it louder for the people in the back. NOT EATING IS NOT THE GOAL HERE!

Your body needs food. Not eating enough will make you tired — and over time, it can stall weight loss by slowing your metabolism and increasing muscle loss.

Fatigue is often a sign that your body needs:
• More protein
• More consistent meals
• Better nutrient density

If you’re unsure what or how much to eat, this is exactly why my team created the Beyond the Shot nutrition guides to remove the guesswork and help you fuel appropriately while still losing weight.

3. Gentle movement increases energy

It feels counterintuitive when you’re tired, but movement helps regulate blood sugar, improve circulation, and increase overall energy. You don’t need intense workouts.
Just a 10–20 minute walk, especially outdoors, can make a meaningful difference.

4. Sleep is not optional for weight loss

Poor sleep doesn’t just make you tired; it directly affects:
• Hunger hormones
• Cravings
• Insulin sensitivity
• Fat loss vs muscle loss

If you’re struggling with energy, sleep quality needs to be part of the conversation. I have personally struggled with sleep and share in this YouTube video exactly what I did to improve my sleep.

5. Consider a multivitamin

I’m not a big supplement pusher, but when intake is lower, it can be harder to meet all micronutrient needs, especially B vitamins, iron, and magnesium.

A high-quality multivitamin can act as insurance while your intake is reduced. I personally take Gruns (use the code GLP1HUBPOD to get up to 52% off) because I don’t like swallowing pills + I like that they have 6 grams of fiber. But honestly, most multivitamins from established supplement brands will work just fine.

When to talk to your provider

If you’re staying hydrated, eating enough, moving, sleeping well, and you are still exhausted, it’s time to check in with your healthcare provider. Fatigue can have many causes, and it’s important not to dismiss it.

If you want more support (and fewer side-effect surprises)

Fatigue is just one piece of the GLP-1 puzzle, but it can really impact your life. If you are really struggling with energy, I also shared this YouTube video with these tips and more.

If you are looking for more support on your journey and a community that GETS IT, consider the GLP-1 Hub Membership where we go deeper into:

• Managing side effects week-by-week
• Eating enough without stalling weight loss
• Improving sleep, energy, and digestion
• Long-term habits that actually stick

I can’t wait to welcome you inside!

On the GLP-1 Hub podcast, I interviewed Dr. Evan Nadler, a pediatric obesity specialist, about GLP1 medications for kids. I had been wanting to cover this important topic for a long time and I am grateful that Dr. Nadler was willing to come on to share his expertise. He definitely gave me some food for thought.

I also interviewed Dr. Maha Tahiri about the impact GLP1s are having on the food industry. She is helping lead the industry towards creating specific guidelines for how to create GLP1 friendly foods.
