Most of myfitness pal is accurate but what you should do is notice there's a lot of duplicate entries for stuff and double check them at first, eventually you know which ones to use and just keep reusing the same ones that you know are good. The other thing is if you're going to do the pro thing and weigh your meat, do it raw. It's a lot easier because the various cooking methods are all over the place for meats. Just weigh it raw, put in the raw weight, and add whatever sauces / toppings + the raw weight. The other thing is try to avoid boxed / processed foods because weighing whole foods is a lot more accurate than a microwave dinner. Do the best you can though, if you're dedicated even small inaccuracies won't set you back too much.

Wait for less than $2 a lb chicken breast sales and stock up. Buy dried beans if you have the time/ patience to cook them (they are the cheapest source of healthy carbs+protein). Actually lentils are great for dried beans, because they don't take that long to cook and if you want them to be easier on the stomach you can sprout them in water pretty quickly for a nutritional boost. Sometimes I cook sprouted lentils with some collard greens and whatever spices. Really healthy and good tasting. Really cheap and easier to make than other dried beans. Go good with a small thin (less calories) tortilla and some cheapo salsa (I usually wait for the giant jug of pace to go on sale for like $3 and get a few). Canned beans are okay if you're too lazy to make dried and can afford them. Eggs yogurt tuna is all healthy and cheap. Get fat from a small portion of nuts (doesn't take much) and fish oil supplements, avocado sometimes if you have an extra buck or two (but don't overdo it on the fat calories). I buy a lot of broccoli and asparagus for my veggies, and steam them in the micro. Cheaper than salads and I don't need dressing to enjoy them. Sometimes I make a salad mix with all the bitter leaves, small broccoli bits, kale, and shredded raw brussel sprouts which i just eat with a little balsamic vinegar and pepper. I don't know why but sometimes I want a really bitter earthy hard to eat salad haha. If I'm not having beans/tortilla with dinner I have half of a sweet potato or a very small one. If I can catch plain chobani greek yorgurt and frozen blueberries on sale that's pretty much dessert for a while, but both those things are a little pricey. If you have some extra cash one month, buying a big bag of fozen pre-cooked shrimp is a good snack for those emergency snack attacks. Just thaw maybe 4 under cold water and a tiny bit of cocktail sauce and you can kind of kill a food craving. That's like 90% of my diet, I've lost about 10 pounds a month for 6 months with that diet, and I've gotten pretty used to it all. Saved a lot of money on food. If I have no food prepared and need quick food I get the new del mexican chicken salad which is cheap and has good stuff in it and salsa for dressing, or I bite the bullet and get el polo loco or chipotle. Costco's pre cooked whole chickens are better /bigger / cheaper than the market ones. Costco also has good talapia and lamb chops (well that's extravagant though haha). I treat myself to a steak every 10 days or so, a food Walmart often has great deals on steaks and they are intermittently phenomenal and at worst decent steaks (better than I can say for my local markets). No money spent on drinks (luckily I have a reverse osmosis for good water). I rarely use oil or butter. I cook most of my eggs in a coffee cup in the microwave, sometimes I'll also put them on a tortilla with salsa. I do occasionally buy the frozen bags of asian stir fry mix and stir fry veggies, but I'm lazy so I've really gotten into the habit of a big head of microwave steamed broccoli and half a microwaved sweet potato.
