What to Clean Out of Your Fridge Before Starting a GLP-1

Starting a GLP-1 medication such as Ozempic, Wegovy, Zepbound or Mounjaro is an excellent excuse to clean out your fridge. This isn’t about chasing the perfect, prettiest curation (though the loose garlic cloves rolling around mine could use some attention). It’s about being a little more intentional with what you keep on hand, so your fridge actually has what your body needs as it adjusts to the medication and its side effects. Ahead, I spoke with two registered dietitian nutritionists (RDNs) about what to clear out, what to bring in and how to make your fridge work for you.

What to Clear Out First—and Why It Matters on a GLP-1

Committing to a fridge edit before starting a GLP-1 isn’t just about maintaining your sanity—it’s about setting yourself up to feel better once the medication kicks in. Being a little more intentional about what you keep (and what you don’t) can go a long way toward comfort and progress.

“The biggest fridge staples to clean out when starting a GLP-1 would be anything greasy, overly rich or heavily processed,” says Hartford, CT dietitian Jessica Crandall Snyder, RDN, medical advisor for FuturHealth. “These foods tend to sit in the stomach longer and can amplify side effects like nausea, reflux, bloating and fatigue. This includes things like creamy sauces, fried leftovers, high-fat deli meats like salami or sausage, heavy takeout and sugary desserts.”

Rochester, MN dietitian Tara Schmidt, RDN, who leads the team at Mayo Clinic Diet, agrees, adding that foods and drinks that provide “empty calories” (high in calories but low in nutrition) are especially unhelpful. Sugary beverages, sweets, alcohol and ultra-processed snack foods can crowd out the protein, hydration and micronutrients your body needs as it adjusts—making them worth clearing out early.

The Foods Most Likely to Worsen Early Side Effects

GLP-1s slow gastric emptying, meaning food stays in the stomach longer than usual. When digestion is delayed, heavier foods can quickly feel uncomfortable, increasing fullness, pressure and nausea. As a result, “high-fat or greasy foods may cause nausea or vomiting,” Schmidt says. Snyder adds that spicy and acidic foods can also intensify symptoms, calling out “pizza leftovers, creamy pastas, sausage, creamy dips and dressings” as common culprits.

When side effects peak, Schmidt adds that texture matters just as much as ingredients, because foods that require less chewing and breakdown are gentler on a slowed digestive system. “Soft, blended or even liquid meals are often tolerated best when symptoms are at their worst,” she says, suggesting options like “overnight oats, eggs, smoothies, Greek yogurt and protein shakes.” She adds that “these types of foods can provide protein, vitamins and minerals, fiber and/or hydration,” without demanding too much from digestion.

The Fridge Swaps Dietitians Recommend Before Your First Dose

Schmidt and Snyder both stress that the goal is replacing—not restricting—so your fridge works with you once you start a GLP-1. If someone wants to prepare their fridge before their first GLP-1 dose, Snyder says three upgrades matter most: a high-quality protein staple, hydration support and easy-to-digest produce:

Protein: Snyder suggests phasing out ultra-processed protein options like bacon, pepperoni and salami, which can be harder to tolerate early on. In their place, she suggests simpler protein sources that digest more easily, such as rotisserie or baked chicken, turkey slices, eggs, shrimp, tofu, tempeh, low-fat Greek yogurt and cottage cheese.

Hydration: Electrolyte drinks, coconut water or infused water ingredients like lemon and cucumber “make a major difference for constipation, fatigue and overall tolerance,” says Snyder. Plus, they’re great for not forcing volume when food doesn’t sound great.

Easy-to-Digest Produce: “Berries, bananas, cooked veggies and simple soups can provide vitamins and fiber in a way that’s gentler early on,” says Snyder. They also help prevent the ‘I can’t eat anything so I’ll skip meals’ pattern.”

For Extra Nutrition Support…

While it’s always important to follow guidance from a qualified health-care provider during your GLP-1 journey, some people appreciate having additional structure and support. Programs like the Mayo Clinic Diet and FuturHealth—both associated with the experts interviewed for this piece—offer resources and provider-guided support to help people navigate nutrition, side effects and consistency while taking GLP-1 medications.
