Why People on GLP-1s Are Using Bariatric Protein Shakes

AmBari Nutrition made its 15g protein shakes originally for people after weight-loss surgery. The idea was simple. After surgery, your stomach is smaller, hunger is unreliable, and regular meals often do not get you enough protein.

A lot of people on GLP-1 medications now run into that same problem.

That is not a marketing hunch. It comes from a post-purchase survey of 1,000 AmBari customers. In that group, 37% had bariatric surgery. Another 22% were using the bariatric shakes with a GLP-1 medication such as Ozempic, Wegovy, or Zepbound.

Different plans, but a similar daily issue: you still need protein, but regular food can make it difficult.

What the survey actually tells us

This was a customer survey, not a clinical trial. It describes how AmBari customers say they use the product. It does not prove that shakes work the same for everyone, or that they replace the plan your doctor or dietitian already gave you.

Here is what stood out.

1. Protein still matters, but hard to get enough

GLP-1 medications can slow digestion and lower hunger. That helps with weight loss. It also makes full meals harder to finish.

In the survey:

• 36% said they use AmBari shakes mainly because it is hard to get enough protein from regular food
• 23% said their stomach can only handle a small serving
• 9% said appetite is too low for a full meal

Weight loss is not only fat loss. If protein stays too low, muscle can come off with it. A small, concentrated shake can be easier to finish than a large plate of food.

Your protein target should still come from your own care team. Needs vary.

2. A shake only helps if you can tolerate it and finish it

These shakes were built for sensitive stomachs. That same design can help people on GLP-1s who deal with nausea or a finicky gut.

• 75% drink an AmBari shake every day or several times a week
• 78% said they almost always finish the full serving

Finishing the serving is the part that counts. An unfinished shake does not add much.

Taste and convenience still matter. About 29% named those as their top reason for using the product.

3. People do not all drink it the same way

• 66% mix it as a drink
• 19% make it thicker, more like a pudding
• 15% switch depending on the day

That flexibility helps when one texture sits better than another.

What this means for you

Bariatric surgery and GLP-1 medications are not the same. But the everyday protein need often is. You need more nutrition than your appetite wants, in a portion your stomach can handle.

A 15g AmBari shake is one practical way some people close that gap. Use it as a tool inside the plan your surgeon, obesity-medicine clinician, or dietitian already set. If nausea, vomiting, or very low intake keeps going, that is a medical issue. Bring it back to your care team.
