What is the cheapest way to get lots of healthy groceries for fitness?

Okay so I am on a tight budget, and I found myself low on energy, hungry, and losing weight. This is tough since I need energy to train in Jiu-Jitsu. Do you have a good grocery strategy for saving money but getting lots of protein and fruits and veggies? Meat kinda can be expensive. Thanks!What is the cheapest way to get lots of healthy groceries for fitness?Participate in a CSA (community supported agriculture) program, if they exist in your area. You get a LOT of fruits and veggies from local farmers for not very much. You could also split your share with a friend or another family. Also, check out places like Costco- they have great produce for cheap (though you may need to share with someone, as it's a lot to eat before it spoils). Frozen veggies can be high in nutritional content and are great when you can't get fresh ones for cheaper. Try adding more eggs, tuna, and beans for cheaper sources of protein.What is the cheapest way to get lots of healthy groceries for fitness?Meat is bad for you anyways. They proved that this year. The type of protein in beans and nuts is the best you can get. You can save money by buying gift cards from people. People who get gift cards from their companies as benefits or for their birthdays sell them. Many of them are gift cards for grocery stores. Look up "gift card" on ebay, craigslist, ioffer, ecrater, places like that. Theres even websites that specialize in gift card markets. For example, last month I bought a target gift card for $350 that had $400 on it. So I saved $50 by going to target and paying with the card instead of cash.
