It is very hard if you live on your own, but the only way I can manage it is batch cooking.
I go to a butcher's when I want meat. I buy exactly enough for me. I really love meat but for ethical and environmental issues I just have a tiny bit of exactly what I want. I even bring my own containers - they just weigh out what I want plus the weight of my container.
Likewise, I go to the greengrocers to buy fruit and veg. They are great there. I just buy what I want, put it in my bag.
If I fall for buying an enormous pack of meat or veg in a supermarket there's a high chance I'll end up throwing away most of it, so it actively saves me money.
Easier said than done, but food is important!
