OP, I recently completed a 50 lb cut under similar circumstances as yourself. You can check my log if you like... I think it starts somewhere about halfway in.
The posts above are correct, but I think they're perhaps arguing about some things that don't necessarily matter yet.
Here's MY general advice in order of importance, it may be wrong, so feel free to ignore it:
1) Cut out the junk... duh. This alone will probably drop 20 lbs over the next couple months.
2) Eat pretty much the same protein on workout and non-workout days... sorry, there's no way around this, really. You may be able to get by w/ .8g/lb if you can handle being a little hungrier, but most suggestions are to go higher for cutting.
3) Measure your food. This is the most tedious part of everything, with the first month being the worse.... but you're making a big difference in your life. Do you really not want to accomplish it because you were so lazy you couldn't spend 2 min. to look up how many carbs are in that cup of milk?
4) If you eat clean, just worry about macros.... calories will be fine.
5) Limit dairy, bread, and nuts to 1/x day each. But don't feel you have to eat any of these.
6) Limit shakes to 2x/day
I'd say that's enough for now.. as you go along, you can implement carb/calorie cycling, periworkout nutrition, and carb ups, but 1 thing at a time. The advantage of carb cycling and periworkout stuff, is it's a good time to squeeze in some junk food like cereal after a workout.... but it's less important than reducing overall cals. Yes, our bodies don't handle all food sources the same, but you aren't at a point where that matters yet.
Re: the saving money
- Buy meat a meat market. Supermarkets cost too much, except for something on special. If you have a hispanic neighborhood around you, they often have meat markets where you can buy in bulk. Asian markets also often offer this. I get 10 lbs of chicken quarters for 7 bucks.
-I don't think low carb is any more expensive than low fat. You like veggies.... stir frying veggies or just throwing some olive oil on top is probably the best way to get your fats in.
-Walmart can also be cheap. Chicken breasts here are $2/lb and I can get tilapia for like $3/lb. Granted, you have to buy at least 5 lbs, but it doesn't last as long as you think.
