RP Diet Coach (by RP Strength, co-founded by Dr. Mike Israetel) and AskBeforeYouEat both put coaching at the center of the eating experience — but they serve very different people. RP is built for serious lifters who want periodized macro prescriptions tied to training phases. ABYE is built for anyone who wants a calmer, more conversational way to eat well. Here's an honest look at both.

RP Diet Coach is one of the most respected science-based nutrition apps in the fitness community. Founded by Dr. Mike Israetel and the RP Strength team, it brings academic-level nutrition science into a consumer app. The coaching isn't conversational — it's algorithmic. You set a goal (cut, bulk, or maintain), log your weight regularly, and the app adjusts your daily macros automatically based on your progress.
For serious lifters and bodybuilders, this is incredibly powerful. The app understands training periodization: it knows that your nutrition needs on a heavy squat day are different from a rest day, and it adjusts accordingly. Users report losing 16+ pounds in a month while keeping the process structured and predictable.
AskBeforeYouEat takes a fundamentally different approach. Instead of prescribing strict macro targets tied to training phases, ABYE gives you a conversational AI coach that helps you think through your meals. Ask "was that a good lunch?" or "what should I eat for dinner?" and you'll get a thoughtful, personalized answer — not a macro prescription.
The philosophy is awareness over restriction. ABYE doesn't assume you're training for a bodybuilding show or trying to hit a specific weight class. It assumes you're a person who wants to eat better, and it meets you where you are.
The choice between RP Diet Coach and AskBeforeYouEat really comes down to where you are in your fitness journey and what kind of coaching you respond to.
If you're a serious lifter who wants periodized nutrition that adapts to your training — and you're comfortable with strict macro targets and regular weigh-ins — RP Diet Coach is one of the best tools available. The science behind it is real, and the results speak for themselves.
If you want nutrition guidance that feels like talking to a knowledgeable friend rather than following a spreadsheet — or if strict macro tracking triggers stress rather than motivation — AskBeforeYouEat offers a gentler path to the same destination: eating well, consistently, without the pressure.
Both approaches work. The question is which one you'll actually stick with. For many people, the app that feels approachable and judgment-free is the one that lasts beyond the first month. That's the bet ABYE makes — and it's worth testing for yourself, especially since it's free.
