Why this matters
Weight-loss drugs like Ozempic, Wegovy, and Zepbound (called GLP-1 drugs) have gone mainstream, fast.
- 11% of US adults are currently taking one for weight loss, up from just 3% two years ago (Gallup, July 2026).
- Some estimates say over 30 million Americans could be on one by 2030 (JP Morgan, Feb 2026)
- US obesity rates have already started dropping because of it — from 39.9% in 2022 down to 36.4% in 2026.
That’s tens of millions of people eating very differently than they used to. Food companies that don’t adjust are going to miss a huge and fast-growing group of shoppers.
What’s actually happening in these people’s bodies
These drugs work by making people feel full faster and stay full longer. That’s the whole point — and it works. But eating a lot less food comes with some side effects that matter for what people should be eating:
1. They lose muscle, not just fat. When you lose weight quickly, some of that weight is muscle, not fat. Studies show this can be a real problem — losing too much muscle can leave people weaker and more tired, and may make it easier to regain weight later if they stop the medication. (And many people do stop — some research found 85% of non-diabetic users quit within two years, usually because of side effects or cost.)
Doctors now recommend people on these drugs eat quite a bit more protein than the average person — around 1.5 grams per kilogram of body weight per day. For a 160-lb person, that’s roughly 110 grams a day, spread across meals.
2. They can end up short on vitamins and minerals. Eating less food overall means eating less of everything — including nutrients people need. A 2026 review of studies covering nearly half a million patients found:
- Vitamin D deficiency in 7.5% of users at 6 months, rising to 13.6% by 12 months
- Iron levels 26–30% lower than similar patients not on the drug
- More than 60% of users not getting enough calcium and iron
- Rising shortfalls in B12 and thiamine over time
Another large study found that 1 in 5 patients developed a diagnosed nutrient deficiency within a year of starting the medication.
This isn’t because the drugs block absorption — it’s simply because people are eating smaller amounts of food overall. Which is exactly the kind of problem food (not medicine) can help fix.
Why protein and fiber are the two nutrients everyone’s talking about
Protein helps protect muscle while people lose weight. This is the single biggest nutrition story in food product launches aimed at this group.
Fiber helps in three ways:
- It keeps people feeling full, which works well alongside the drug
- It helps smooth out blood sugar swings
- It helps with digestion — GI issues (nausea, constipation) are actually one of the top reasons people quit these drugs, so fiber and hydration can help people stick with treatment
At the big 2026 food industry trade show (IFT FIRST), the most common new-product idea wasn’t protein alone or fiber alone — it was the two together. One example: a protein soda combining pea protein with a soluble tapioca fiber, aimed at hitting satiety, muscle support, and gut health all in one drink.
What this means for building products
Give people real protein and fiber in each serving, not a token amount. A good rule of thumb: aim for 15–25 grams of protein and 5–8 grams of fiber per serving in something meant to be a meal or real snack for this group. That’s meaningfully more than a “high protein” snack of a few years ago.
Don’t sacrifice taste to hit the numbers. This is where a lot of products fail. Cramming in protein and fiber often makes food taste chalky, bitter, or leave a weird aftertaste. Since these consumers already deal with digestive sensitivity, a bad-tasting product gets abandoned fast — not just disliked. Worth extra time and testing here, especially at the higher end of your protein/fiber dosing, not just the minimum needed for a label claim.
Go smaller, not bigger. People on these drugs eat smaller amounts, more often (if at all). Smaller, denser, nutrient-packed formats — bars, shots, small ready meals, fortified soups — fit their new eating pattern better than big portions.
Think about vitamins too, not just protein and fiber. Given the documented gaps in vitamin D, iron, calcium, and B12, there’s a real, evidence-backed case for fortifying products for this audience with these specific nutrients — not just generic “vitamin added” claims.
Don’t forget hydration. Reduced eating often comes with reduced drinking too. Beverages and electrolyte-forward products are a natural fit here.
This market is bigger than just people on the drugs. A lot of people who aren’t on medication are also chasing high-fiber, high-protein eating right now (fiber has become its own social media trend). So these products have a bigger audience than just medication users — just be careful not to imply a food product works like the drug itself. That’s both untrue and a legal risk.
Quick-reference table
| What to think about | Rough target | Why it matters |
|---|---|---|
| Protein per serving | 15–25 g | Helps protect muscle during weight loss |
| Fiber per serving | 5–8 g | Supports fullness, blood sugar, and gut comfort |
| Key vitamins to consider | Vitamin D, iron, calcium, B12 | These are the nutrients most commonly running low |
| Portion size | Smaller, more nutrient-dense | Matches how much less people are eating overall |
| Taste testing | Extra rounds, especially at high protein/fiber levels | Off-tastes cause fast abandonment in this group |
| Claims | Keep specific and honest | Avoid implying a food “works like” the medication |
