This is your issue. You’re an omnivore, and it sounds like you’re overemphasizing meat. Buying primarily plant-based items will greatly cut down your grocery bill, and hopefully introduce you to some delicious new recipes on the process.
I’d recommend checking out Greek, Italian, Indian, Japanese, and Ethiopian recipes for some extraordinarily flavorful and filling vegetable-heavy meals that are relatively cheap. With Japanese, focus on buying tofu rather than meat since its cost should be generally cheaper.
I was omnivore for fifty years plus, vegetarian for several years, and even raw vegan for a while. But gastro issues made me go low residue and diabetes made me go low carb. Carnivore is what's left. Though I've been coerced into it, it has increased my healthspan a good bit.
Tofu is on the low side of carbs and fiber for plant food, but I believe that the fat and protein profiles and nutrient availability are better from meat.
The point is cost of his diet has gone up, which happens with meats - immigration has permenantly driven up up cost of many offcuts because now they're used in more recipes now. But still pretty telling when "medium" cuts prices are going through the roof. There's still "economical" carnivore diets considering how much industry is subsidized, not as economical as just hammering beans, but if one eats a lot of meat, one notices.
