Diet combinator

Collaboration is welcome — feel free to reach me out!

Sport/longevity diet combinator. Takes into account calories, fats, proteins and carbs proportion.

Project vision

Aims

Should automatically form list of groceries.
Shopping should be done weekly.
Maximum easy, no complicated recipes

Roadmap

No go

For developers: no time for front-end/nice UX right now.

In the near future:

✅ Price minimization.
✅ Diversity balance.
Super simple recipes. For instance: kefir + oat flakes. Cause it's almost impossible to eat oat flakes without kefir
min/max daily and weekly values (i.e. avoid much nuts a day, but consume some minimal amount of olive oil)
Weekly plans: some products should be eaten several times a week only.
Improve readability of the output.

Theory

Slang

fpc = Fats, Protein, Carbs
cfpc = calories, fats, protein, carbs
gi = glycemic index

Info

Fats slow down digesting of carbs, so when you are eating them decreases glycemic index. It works also in case of frying with lots of oil. That's why smashed potato has a higher GI than potato chips [1], and fat-free milk has a higher GI than jut a normal milk [2]
