Meal Replacement Bars for Weight Loss

Meal Replacement Protein Bars

Our meal replacement protein bars contain enough protein to keep you full for hours, provide enough calories for a healthy diet, and supply the vitamins and minerals you'd otherwise get from a plate of food. 

Our Wonderslim bars contain 15g of protein, 4–5g of fiber, 160 calories, and 20 added vitamins and minerals per bar. The protein and fiber slow digestion, so one bar holds you between meals rather than causing hunger pangs an hour later.

Proteins Blend That Digest at Different Speeds

Each bar features a protein blend which may include calcium caseinate, soy protein, whey, and milk protein isolate. They all digest at different speeds, releasing the essential amino acids over a period of several hours,  instead of all at once. Together they cover all nine essential amino acids, which protects lean muscle and regulate energy, even while you're in a calorie deficit. 

FAQ

Is a meal replacement bar the same as a protein fiber bar?

No. A meal replacement bar is built to stand in for a meal with more calories and a fuller set of vitamins and minerals while a protein fiber bar is a lighter snack that pairs protein with added fiber to hold off hunger between meals. 

How many meal replacement bars can I eat in a day?

One or two works for most plans with each one replacing a meal like breakfast or lunch. Build the rest of the day around whole-food meals and count the bars toward your daily calories rather than adding them on top.

Will one bar keep me full until my next meal?

Yes. The slow-digesting casein in the protein blend and up to 5g of fiber release over a few hours, so one bar holds off hunger the way a light meal would. 

Can I use meal replacement bars on a GLP-1 medication?

Yes. The high protein suits the smaller appetite that comes with GLP-1 medications and helps protect lean muscle while you lose weight. Check with your prescriber about how bars fit your overall nutrition plan.
