Reverse Age Lab vs MyFitnessPal
One logs what you ate. The other works out what you should take.
A friend of ours said MyFitnessPal is "sort of close on the diet and exercise side". Fair. Here is where the two overlap, where they do not, and why plenty of people use both.
What MyFitnessPal does best
- The largest food database of any diary, with photo and voice logging and a barcode scanner on the paid plans.
- Calorie and macro goals, a weight trend and an exercise log, refined over almost twenty years.
- A free plan that covers basic logging, and Premium at $19.99 a month or $79.99 a year for scanning, custom macros and no ads. Premium+ adds meal plans at $24.99 a month or $99.99 a year.
- It sells no supplements either.
What MyFitnessPal does not do
- Grade a supplement. A capsule is logged the same way as a banana: for its calories and nutrients.
- Check what you take against your medications, or tell you what to stop.
- Build a schedule of what to take and when.
- Read your blood work, or compare it to what you eat.
- Read your stack from a photograph.
- Tell you whether the evidence for a product is human trials or marketing.
What Reverse Age Lab does
Rala grades every supplement on six evidence tiers from human studies, real reviews and what the top 10 biohackers say, then builds one daily protocol from your total health profile. It is not a food diary, and it does not try to be one.
- Upload your blood work, store it and track it over time.
- Compare your blood work to the nutrition facts panel built from your own diet and supplements, which is the part a diary cannot do on its own.
- Take pictures of your stack and upload it.
- Conflicts, interactions and redundancies across supplements and medications.
- Suggestions based on your goals.
- Goals, diet, exercise, supplements, medications and test results as one input, with a Diet, Exercise and Nutrition module for people who want that side built out.
