I live in a van now so I can travel the United States for cheap, I literally own nothing besides my van and what is in it, I sold everything save for a small tucker tote of photos I store at my sisters house in San Diego. I am still Vegan to the core, but I have no gym, so I use 20lbs worth of chains and locks, and my suspension straps to workout, as well as any structure I can work out off of. What working out with my body weight plus a little extra has taught me is that I can challenge myself without a gym, the simplicity it has brought to my life encourages me to continue with my minimalist mentality.
I don't really count calories, I eat when I am hungry and stop when I am satisfied. Typical fare includes two or three peanut butter and fruit spread (not that sugary jelly crap) sandwiches, 2 or 3 servings of fruit, 2 servings of veggies, a serving of nuts, a few glasses of soymilk, a bowl of sprouted beans or legumes with a bit of olive oil or avocado, or a can of soup or beans of some sort, and a bowl of cereal or a bowl or two of oats. I like dark chocolate or cacoa nibs for snacks. I also drink a cup or two of coffee and half a 64oz jar of tea a day, plus a lot of water.
I think calories are abstract and are a flimsy measurement, but it works out to 2000-2500 a day. I don't have to force all this food down, it seems to be what my body prefers.
My gear, I'll be investing in a 40lb weight vest that accept standard plates and 25lbs of plates to start, plus a dumbbell or kettle bell handle. I am also going to buy a hydration lumbar pack for when I jog or sprint. Maybe next month, because I had to buy new shocks for my van.
Life is simple and awesome.
