Have you tried roasted a chicken? A whole chicken costs $6. Feeds 2 with leftovers, the bones can be used for broth, which can make lots of things, especially soup. The leftover meat is great for many things, like fried with potatoes. Sometimes I find that the chicken was used for 10 meals. Of course other things are added along the way, but veggies are dirt cheap.
That means you blew your 3-day food budget on half a chicken. That's just not nearly enough calories for 3 days. I'm not doubting you're able to afford chicken on that tight budget, it just seems that you're using it more like a condiment, rather than food.
You don't get all your calories from the chicken. And yes, it's more like flavoring. You round out the meal on veggies and maybe some simple carbs. The US fascination with a protein-heavy diet is, uh, fascinating.
I'm not from US, I didn't imply that he must get all his calories from chicken and I'm not the one who brought up the chicken in the first place. He seemed to imply that chicken is a significant part of this diet and it simply isn't possible on such a budget. That was my point.
Even in the middle of Mississippi, I don't see how one person can get a desirable amount of quality calories and vitamins on $1 per day. There would have to be some kind of triage such as never exercising or farming one's own vegetables going on, or skipping meals.
