I switched to veganism (mostly of the McDougall variety) and lost 10lbs quickly. In my case, weight loss wasn’t the goal as much as blood pressure, and a few other health benefits. My dad is also on it, and is down to his post-basic-training weight. Within three weeks, I went from having the highest blood pressure of my adult life to having the lowest. It’s pretty hard to gain weight on his diet. I’ve done it once before (when I was much younger and more active), and I had to eat almost 2x my normal portion sizes to maintain weight.
