Best Protein Shakes and High-Protein Foods for GLP-1 Medications

One of the first things people notice on a GLP-1 medication like Ozempic, Wegovy, Mounjaro, or Zepbound is that they just aren’t hungry. A few bites in, you’re full. Some days, food sounds downright unappealing.

That can feel like a relief at first. But eating less overall usually means eating less protein too, and protein is the nutrient you most want to protect on these medications. It helps preserve muscle, supports healthy hair and skin, keeps your energy steadier, and helps you feel your best while your body adjusts.

The good news: you don’t have to force down giant meals. A few smart swaps and some grab-and-go favorites can close the gap. Here’s what our dietitians actually recommend, and how to size up any product on your own.

Why protein matters so much on a GLP-1

When you eat less, your body still needs building blocks for muscle, bone, skin, hair, and your immune system. If protein intake drops too low, your body can start pulling from muscle to meet those needs.

That’s why a lot of the side effects people search for on GLP-1s, like muscle loss, thinning hair, and the change in facial fullness nicknamed “Ozempic face,” often come back to the same question: are you getting enough protein?

How much protein do you need on a GLP-1?

It depends on your body, activity level, and health history, so there’s no single number that fits everyone. A practical starting point for many adults is 20 to 30 grams of protein at each meal, with protein-rich snacks filling in when meals are small.

When appetite is low, it helps to eat your protein first at each meal, before the rest of your plate fills you up. If you’re not sure you’re getting enough, a dietitian who offers a GLP-1 nutrition support program with a dietitian who can set a target that fits you and help you reach it without overthinking every bite.

Can you just drink protein shakes on a GLP-1?

This is one of the most common questions, and the answer is: shakes are a great tool, not a full plan.

Protein shakes shine on days when appetite is low, when nausea makes solid food hard, or when you need something fast. They’re easy to sip slowly and often go down easier cold.

But food brings things shakes can’t fully replace: fiber, a wider range of vitamins and minerals, and the satisfaction of an actual meal. Most people do best using shakes to fill gaps, not replace every meal.

Our dietitians’ favorite protein shakes

These are the ready-to-drink shakes we recommend most. We’re not paid by any of these brands; these are simply the ones our clients tend to like and tolerate well. All hit around 25-30 grams of protein per serving.

Fairlife Core Power and Fairlife Nutrition Plan. Our top pick for taste. Both are made with ultra-filtered milk and are lactose-free, which helps if dairy usually bothers your stomach.

Nurri. Another tasty lactose-free option, lower price point compared to the Farilife shakes.

Premier Protein and Pure Protein. More budget-friendly and and available in more flavors than most brands, so it’s easy to find one you actually love.

Protein powder: the most flexible option

Optimum Nutrition Gold Standard Whey is our go-to powder because it mixes well and doesn’t get clumpy. It’s also more versatile than a shake. A few ways to use it:

• Stir it into overnight oats
• Blend it into a smoothie
• Add a scoop to protein pancake mix
• Mix it into Greek yogurt for extra flavor and protein without adding more volume, which matters when you fill up fast

That last one is a favorite. On a GLP-1, the goal is often more protein in less space, and powder mixed into foods you already eat does exactly that.

Protein bars and snacks

When you only have room for a few bites, snacks do a lot of heavy lifting.

Barebells and FitCrunch protein bars. Tastes more like a candy bar than a protein bar.

Chomps meat sticks and Epic turkey or chicken jerky. Savory, portable, and easy to keep in a bag or desk drawer. These can be higher in sodium, so keep that in mind when planning your day.

Fiber bars for the constipation side of things

Constipation is one of the most common GI side effects on GLP-1 medications, partly because you’re eating less overall. Fiber can help, and these are two easy options:

NeuoFiber bars and Fiber One granola bars.

One caution: add fiber gradually and drink plenty of fluids with it. Adding a lot of fiber at once can cause gas and bloating, which is the last thing you need if your stomach is already sensitive.

High-protein foods for GLP-1

Shakes and bars are convenient, but real food is still the foundation. Here are easy high-protein foods that tend to work well when appetite is small:

• Greek yogurt or skyr
• Cottage cheese
• Eggs or egg bites
• String cheese
• Chicken, turkey, or tuna salad
• Salmon or other fish
• Tofu or tempeh
• Beans, lentils, and edamame
• Deli turkey roll-ups
• Milk or ultra-filtered milk

Softer, moist foods often go down easier than dry, heavy ones on days when your stomach is unsettled. Smaller portions more often can help too.

And you can still build a balanced plate. A plate in thirds (protein, carbohydrates, and fruits and vegetables) works well. On a GLP-1, the thirds just get smaller, and protein goes first.

How to read the label on a protein shake or bar

You don’t need to memorize every number on the Nutrition Facts panel. When you’re comparing products, these are the things worth a quick look.

Protein per serving. For a shake meant to fill in for a small meal, look for at least 20 to 30 grams. For a snack bar, 10 to 15 grams or more is a good target.

Sugar. Some bars are closer to dessert than a meal replacement. Aim for less than 10 grams of total sugar per serving, especially if you’re also managing blood sugar.

Sugar alcohols. Ingredients ending in “-itol” (like maltitol or sorbitol) keep sugar low but can cause gas, bloating, or diarrhea, which can stack on top of GI side effects you may already have. If a bar bothers your stomach, check for these first.

Fiber. Helpful for constipation, but increase it slowly. 2 to 5 grams per serving is a great place to start. Most people need around 28-35 grams of fiber a day.

Serving size. Make sure the numbers you’re reading match the amount you’ll actually eat or drink. Some containers hold two servings.

Words like “GLP-1 friendly.” This isn’t a regulated term. Plenty of products marketed for GLP-1 users are regular protein shakes with a new label and a higher price. The Nutrition Facts panel tells you more than the front of the package.

Quick label checklist

• The Nutrition Facts panel, not the front-of-package claims
• 20 to 30 grams of protein per shake, or 10 to 15 grams per bar
• 10 grams or less for total sugar
• Few or no sugar alcohols if your stomach is sensitive
• 2 to 5 grams of fiber to start
• A serving size that matches what you’ll actually eat or drink

Tips for getting protein in when you’re not hungry

• Eat protein first at every meal
• Keep ready-to-eat options stocked so you don’t have to think about it
• Sip shakes slowly over 20 to 30 minutes if drinking one all at once feels like too much
• Try cold or frozen options, which are often easier on nausea
• Don’t skip meals entirely, even if the meal is just a few bites

GLP-1 protein FAQs

What is the best protein shake for GLP-1 users? The best shake is one with enough protein (at least 15 to 20 grams), low added sugar, and a taste you’ll actually drink. Our dietitians’ favorite is Fairlife Core Power, with Premier Protein and Pure Protein as budget-friendly options.

Can you drink protein shakes with Ozempic? Yes. Protein shakes are a common and helpful way to meet protein needs on Ozempic and other GLP-1 medications, especially on low-appetite days.

Are shakes marketed for GLP-1 users better? Not necessarily. “GLP-1 friendly” isn’t a regulated term, so compare the Nutrition Facts panel instead of the front label.

What are good high-protein foods on a GLP-1? Greek yogurt, cottage cheese, eggs, fish, chicken, tofu, beans, and string cheese are all easy options that pack protein into small portions.
