Look up college bodybuilding diet plans.
Eggs (with yolk)
Beans
Maize
These 3 make up a large part of a diet in many parts of the world (e.g. Rift Valley, Kenya).
Personally, I would rather take out loans than not eat healthily.** Even just an extra $1000 or 2000 dollars can provide you with ample salmon (frozen), tilapia, cod–eve**n scallops or crab occasionally (frozen) for the year, along with a ton left over for high quality meats and produce.
Spend couple grand here, save it on future medical bills and feel amazing.
Ground beef, turkey.
Chicken breasts.
Many cuts of pork.
Sweet potatoes
Regular whole potatoes (Russet, Idaho, Red, Yukon, etc.)
Frozen vegetables
Cabbage (lasts forever)
Brown rice (cheap as)
Brown pasta
Quinoa
Butter (full fat)
Olive oil
Omega 3 Fish Oil supp.
Cut the carbohydrates from the diet that aren’t “natural” (yes, a loaded word, still using it here)–e.g. coke, bread, pie
Summary/tl;dr:
Focus on high satiety index foods/whole foods/foods that were probably around 100 years ago as a general rule
My roommates and I got absolutely stacked on these types of foods (sort of paleo/natural).
Also consider intermittent fasting 3:4 or 4:3 (Google it).
