How do you separate compound effects from diet changes?

I've been wondering how anyone can tell what is truly responsible for a result when multiple variables influence the same endpoint. Weekly calories could stay roughly constant, yet appetite, the timing of meals, water retention and training can each move the scale.

When someone is looking into a stack of compounds, it becomes even trickier, because a shift in weight or hunger doesn't reveal which of the factors is behind it.

To those who keep up with research on GLP-1s and other peptides, what would your method be for comparing outcomes across a few weeks? Which would you put first — bodyweight averages, waist measurements, appetite changes or training performance — and how long would you let each trend run before you conclude anything?

This is giving research study. How dare you. Lol jk

Personally, I step on the scale every day, which makes it simpler to follow trends rather than fixate on the actual number. I’m not big on logging anything, but I can gauge things from how I feel, how my clothes fit, and how much weight I can move on different machines.

My stack is very complex, though almost everything in it serves a specific use case.

Telling these apart might not be something that can be done in any rigorous way. That's the reason someone using GH peptides alongside GLPs has no way of telling whether the GH is contributing to fat loss. There are times when doing less works better — for example, staying away from steroids and growth hormones while using GLPs for weight loss.

The simplest approach: alter a single variable while keeping all the rest constant for a few weeks. If you don't, you're only guessing which lever made the difference. Tracking a weekly average of daily weigh-ins alongside a weekly waist measurement covers most of what matters, because water, salt and carbs can make the scale jump a kilo or two from one day to the next. Appetite and gym numbers are worth recording, but since they're noisy, I'd wait 3-4 weeks before treating any trend as real.
