$1.30 per day food budget? Not accurate in the affluent world. 1400-1800 calories for an average height adult male is a reasonable floor (and that's a non-obesity scale). The $1.30 per day budget might get you around 1/3 of that calorie requirement, without solely existing on something like rice. You can get by on closer to ~$90-$120 per month, per adult, and actually bring in enough calories to not starve over time. That's a surviving floor. You can temporarily go a bit lower to scrape by ($50-$90), however that's not livable longer term, you'll suffer increasingly. If you modestly augment with various free food assistance options (not talking about SNAP), you could stretch the lower ~$50-$90 category up to something more like the $120 category consistently.
