Protein is the one macronutrient you cannot afford to under-eat on a GLP-1. Everything else can be forgiving. Protein is not.
The number the research supports
For adults in a calorie deficit who want to preserve lean mass, the research consistently lands in the range of 1.4 to 1.6 g of protein per kilogram of body weight per day. If you are training with weights, the upper end of that range is the safer target.
In pounds, at a body weight of 180 lb, that works out to roughly 115 to 130 g of protein per day. That is a lot when your appetite is down 40 percent.
Why protein is built into Daily Foundation
Protein only matters at a real dose. The research points to needing at least 20 to 30 g per serving to move the needle, so a token sprinkle does nothing. That's exactly why Daily Foundation includes a full 25 g of whey protein isolate in every scoop, not a marketing dusting. It's cold-processed with no creamer fillers, and we include a lactase enzyme so it digests easy on a sensitive stomach.
One scoop covers a genuine 25 g toward your daily target. The rest is easy to reach from food across the day, which is what the next section is about.
How to actually hit your target
Daily Foundation gives you 25 g of high-quality whey isolate to start. The practical goal is to cover the remainder from food across the day, which is where most people still fall short.
- Front-load breakfast. Eggs, Greek yogurt, cottage cheese, or a shake. Aim for 30 to 40 g in the first meal, before appetite drops off.
- Anchor lunch and dinner around a palm-sized portion of a lean protein: chicken, fish, tofu, lean beef, or a legume.
- Keep an easy shake or ready-to-drink protein in the fridge for the days you cannot stomach a meal.
- Track for one week only, to calibrate what your usual meals actually add up to. Most people are 40 to 60 g under target on their normal rotation.
The takeaway
Daily Foundation starts your day with 25 g of whey protein isolate plus the muscle-supportive nutrients (creatine, HMB, D3, K2, minerals) that help protect lean mass while the scale drops. Your job at mealtime is to cover the rest of your protein target from food, which is still the hardest part on a suppressed appetite.
