Before going Vegan I used to be heavily overweight - when I was 19 I weighed over 250 pounds, I stopped weighing myself at that time because it was just too depressing. I found the Body for life program, followed it and lost around 90 pounds in a year a half. When I went vegan four years ago I dropped about another 8 - 12 pounds.
I've been vegan for four years now and I've hovered around 150-154 pounds for the last three years or so and recently wanted to start gaining mass and strength. I've gained 20-25 pounds in the past four months - I last weighed in at 174 pounds. I ate a ton of food, 3,000-4,000 calories plus a day and worked out 3-4 days a week doing heavy compound exercises and going straight to failure. I didn't do any conditioning or cardio and averaged about one yoga class a week. A lot of what I ate was purely whole foods like copious amounts of steamed and raw kale and other veggies, lots of beans, tempeh, sweet potatoes, brown rice, quinoa, sprouted bread, steel cut oats, fruit, tons of water - 5+ litres a day - and more recently tofu.
I have noticed significant strength gains and my weight has gone up but I definitely have developed a bit of a spare tire. I think that I genetically store any excess calories as fat. I'm now going to eat about 2,400-2,600 calories a day, still do the heavy compound lifts but will start to include 5 conditioning days a week - hopefully in the AM on an empty stomach. I'll be hitting the weights in the PM and if I can't complete an AM conditioning session then i'll just tag it onto my PM workout - unless i'm completely gassed from a leg workout. My goal is to continue to increase strength gains, lose the spare tire and find my perfect ratio of daily caloric needs.
I'll post workout log and food log later on tonight when I get back from the gym. Shoulders and legs today!
