WHEN MEALS GET SMALLER

The plate changes. The protein question stays.

Some days, a few bites feel like enough. The meal ends, but you still want to know what you got from it. For adults 45+ eating smaller meals, including people using GLP-1 medication, protein can take more planning.

Rebuild gives you one serving you can count: 22 g whey isolate protein. Build the rest of your day with protein-rich food, a personal target, and suitable strength activity.

A nutrition step alongside food and care—not a treatment for medication effects or a complete meal.

  2. Fewer protein opportunitiesThere may be less room for protein-rich food.
  3. One measured stepTwo scoops of Rebuild add 22 g protein.

A CLOSER LOOK AT THE LABEL

Two cocoas. One protein routine.

Whey isolate is Rebuild’s sole listed protein source. Cocoa and MCT oil powder are also in the scoop—here is what the Chocolate label actually says.

CHOCOLATE · TWO COCOA POWDERS

Chocolate made for a repeatable routine.

Nidau and Nightfall cocoa powders are listed on the Chocolate label. They put actual cocoa behind the chocolate flavor—a familiar reason to reach for your protein shake.

BOTH FLAVORS · MCT OIL POWDER

Already blended. Nothing else to pour.

MCT means medium-chain triglycerides. MCT oil powder is listed in both flavors, so there is no separate oil to measure. One full two-scoop serving gives you 22 g protein and 120 calories mixed with water.

The ingredient images are illustrative. The label does not state separate amounts for cocoa or MCT oil powder. Read the complete Chocolate ingredients and nutrition facts

WHY THE PROTEIN STEP MATTERS

Less appetite can mean fewer chances for protein.

A smaller plate can be part of a changing routine. This visual guide shows where dietary protein fits—and what one full serving of Rebuild actually adds.

The changing meal

Full sooner can mean less room on the plate.

GLP-1 medicines can reduce appetite. If a meal ends early, there may be fewer chances to include protein-rich food. The illustration shows one injectable route; oral forms also exist.

The body’s use

Protein supplies amino acids.

Your body uses amino acids from dietary protein throughout its tissues, including muscle. Adequate food and suitable strength activity matter too; a powder alone cannot promise to preserve muscle.

Why this tub

A serving you can actually count.

Rebuild lists whey isolate as its sole protein source. One full serving adds 22 g protein, with 120 calories when mixed with water. The actual label is available below.

One step, not the whole plan: Use Rebuild alongside protein-rich food, a personal target, and strength activity that fits your ability.

Choose your supply

What the research supports. In a four-week randomized trial, 40 young men ate lower or higher daily protein while doing intensive resistance and interval training six days a week during a calorie deficit. The higher-protein group gained an average 1.2 kg (about 2.6 lb) of lean body mass, versus 0.1 kg in the lower-protein group. Read Longland et al. This trial did not study Rebuild, GLP-1 users, or adults 45+; it cannot predict an individual result.

ADA guidance recommends attention to adequate protein and muscle-strengthening activity during weight reduction. It does not establish a Rebuild-specific outcome. Read the guidance.

View whey studies and sources

Two small trials in older men studied 20 g of whey isolate and measured short-term muscle protein synthesis. They did not test Rebuild or long-term outcomes in adults taking GLP-1 medicines. A trial in women during weight loss found no meaningful muscle or strength protection at 10% weight loss.

BEFORE THE FIRST SCOOP

Good questions deserve clear answers.

How much is one serving?

Two scoops (35 g) provide 22 g protein and 120 calories for the powder. Mix with 6–8 oz water or another beverage; other mixers add their own nutrition.

Why is Chocolate 35 g and Vanilla 34 g per serving?

The flavor blends have different labeled scoop weights. A full two-scoop serving is 35 g for Chocolate and 34 g for Vanilla. Both flavor labels state 22 g protein and 120 calories per serving of powder.

Does one shake meet my daily protein goal?

No. Rebuild contributes 22 g per serving. Your total goal is personal. Keep protein-rich food in your meals and ask your healthcare professional or dietitian for a target that suits you.

Will this prevent muscle loss on my GLP-1?

No product can guarantee that. Adequate daily protein and suitable resistance activity belong in a plan to support lean mass during weight reduction. Rebuild adds 22 g protein per full serving and can help you work toward a personal protein target, but it has not been studied to prevent muscle loss in people taking GLP-1 medication. Discuss your target and activity plan with your clinician.

What about changes in the mirror after weight loss?

Some people notice a less full face or looser-looking skin after substantial weight loss, with or without medication. Rebuild adds protein to a nutrition plan; it does not restore facial fat or tighten skin. Read the American Academy of Dermatology’s explanation.

Can I use it while taking a GLP-1 medication?

Rebuild is a whey protein supplement, not a medication. If you have a medical condition, dietary restriction, or questions about your care plan, check with your healthcare professional before use. It has not been studied as a treatment for GLP-1 side effects or medication interactions.

Does it contain dairy or lactose?

Yes. Whey isolate comes from milk, and the label lists milk as an allergen. Rebuild is not labeled lactose-free, and we do not have a verified lactose amount. If you are lactose intolerant, review the ingredient label and decide with your clinician whether it fits your needs. It is not suitable for someone with a milk allergy.

How long does one tub last?

There are 24 two-scoop servings per tub. At one serving a day, one tub lasts 24 days.

Can I buy it once?

Yes. Choose “Buy once” above. If you select subscription, check the charge and renewal schedule before adding to cart and again at checkout.

What if Rebuild is not for me?

Try it for 60 days from delivery. Opened tubs qualify. Email hello@keptstrong.com with your order number within 60 days; no return is required. We refund the product price and sales tax, excluding original shipping. Read the full Rebuild terms.

Let the weight change. Keep strength in the plan.

The next step is small: two scoops, one glass, 22 g of protein added to your day. Build the rest with food, strength activity, and care that fits your life.
