I like to think of myself as a pretty typical dude. I work a good job. I work from 6:30 am - 3:00 pm (Mon-Fri) at an office as a software developer. I've always been a morning person, and my boss respects that. My hours are the way they are because I don't take lunch breaks or smoke breaks. I eat all four meals at the office while working (or posting on t-nation!). Saturdays and Sundays, I make my meals fresh at home and/or eat smart while I'm out and about. Also, I am at the gym from about 4:00 pm to 5:15 pm but I'm only ingesting the protein and carbs from 4:00 - 4:45 pm. After that, it's just plain water.
As far as what I eat...here's a breakdown of quantity and price:
I get my steak from a local butcher who sources grass-fed, non GMO beef, chicken, and pork...so my steak is usually one big cut (2.5 lbs ish) and that'll last me about 6 meals (ish). I love flank-cuts of steak (flank steak, skirt steak, bavette steak, etc). Better texture, but a bit pricier than other cuts. The steak is the only "pricey" item I buy ($12.99/lb to $15.99/lb). But then I go to Wal-Mart and Kroger.
The chicken is $1.99 lb from a grocery store (Kroger, if you're familiar). I go through, roughly, 10-11 lbs of chicken a week, but that covers 21+ meals.
Sometimes I splurge and buy 30 lbs of chicken when it's on sale and freeze what I don't use right away. That's always been my secret: Find chicken when it's $1.69/lb and spend $75 dollars...take it home, cut off the fat, wrap in plastic wrap, place in bag, put in freezer. Thaw what is needed and cook it. It sucks for cash flow up front, but it saves a lot of money annually.
Sometimes I save money by purchasing chicken thighs (they're cheaper if you haven't looked at them). The skin adds fat into your diet, though. And if you try to use them for meal prep, you have to cut around the thigh bone...and it can be a pain in the ass.
Eggs I can get for sub $3.00 for 5 dozen at Wal-Mart. Not the best quality, but I'm not a pro-bodybuilder. Lately, 5 dozen eggs (60) have been about $2.50. Sometimes that jumps up to $5.00 depending upon market prices. But that is really cheap either way, and will always be cheaper than buying bottled egg whites.
I buy jasmine rice by the 5lb bag at Wal-Mart for not very much money. I think a 5 lb bag of Jasmine Rice at Wal-Mart is $4.50 or so. But rice goes a long way. Wal-Mart has also upped their game on produce...and their prices are cheaper than many other grocery stores.
I go back to Kroger for frozen veggies, though. Just a preference.
I use a hydrolized protein and a whey protein. I use one scoop of the hydrolized on days that I lift (6 scoops a week, half pre, half intra). I use between 1-2 of the whey only on days I lift (let's average 9 scoops, all post gym). That's only 15 scoops-ish of protein powder a week. I'm not sure where you got 40-42 scoops from...
When I average it out, my grocery bill is just about $100 a week...which isn't bad at all, in my opinion. It's a lot more than my tiny lady would spend on herself, but it's pretty cheap for someone that lives a bodybuilding lifestyle. Copuons are essential too...online and in the mail.
