a few friends were asking me about nutrition, saying "eating healthy costs so much money!", which it can, but i always thought people were being unoptimal with their diets, so eventually once i began making more food for myself, i crafted this meal (don't solely eat one thing, variety is important) which is the base of my macros on most days

complete macros shake

Ingredient Amount
fairlife 2% milk 3 (720 ml)
vanilla protein powder ~60 g
chia seeds 30 g
almond butter 32 g
frozen strawberries 300 g
1 banana 120 g
frozen spinach 60 g
creatine 5 g

this should be split up between 2 shakes or so

then eat a peanut butter and banana sandwich on whole wheat bread.

if you buy store brand (except fairlife) and in bulk, you can get this for around ~7.50 a day, and the macros are

Amount
calories ~1,620
protein ~121 g (30%)
carbs ~158 g (39%)
fat ~64 g (35%)
fiber ~34 g

it does not get all micros choline (eat an egg), EPA/DHA (fish), etc. but you have a lot of calories to spare getting all your thiamin, folate, zinc, etc. just do your research before eating only what i tell you to :)

electrolytes

Ingredient Amount
fine iodized table salt 498 g
potassium chloride 75 g
magnesium citrate/malate powder 79 g
citric acid 349 g

i do a fair bit of running, and while the electrolyte hype is supposedly overblown, i have personally always thought that 1. it makes me feel like i recover better (even if there is little evidence that i'm underhydrated otherwise). 2. electrolytes are incredibly expensive for what they are. so here is a very simple and cheap way to make the optimal electrolyte mix, just shake this in a jar and add a teaspoon into 30 oz of water and add water flavorings to taste, unless you like tasting sea water :)
