Yah I'm a whole food vegan. Some of the premade vegan foods may actually be worse than eating meat, at least in some regards. Meat substitutes making the top of that list.
I also love to eat! But you wouldn't know it by looking at me. Given what I eat, mostly whole grains, beans and vegetables dressed up in all kinds of delicious ways. I can eat to my hearts content without over eating. At least with respect to calories.
I had the advantage of having a early wake up call regarding my weight. At my heaviest I was 220 at 5' 11". Which is overweight. But I have a younger sister, and cousin who have put on a lot of pounds. Cousin drinks a lot of beer, both eat a lot of fast food. So those were the first things I cut out. Since then I've progressed from one diet to the next. In many cases because they left me hungry.
I lost 50 lbs across many diets. Along with a lot of cardio exercise. I was happy with my weight but still had high blood pressure. I tried the vegan thing and my blood pressure came down. Along with it I lost the tummy bulge I always struggled with. Now I can eat as much as I like. Yay! So long as I'm eating the right things. And I've lost 15 pounds without any exercise and never feeling hungry. Kinda feels like cheating.
I know vegan isn't everyone's cup of tea. But as I worked my way through many diets I noticed that the better a diet seemed to preform, in regards to both health and weight loss, the less meat and dary people were eating on it. Which has pushed me to the extremes I suppose, but it works for me.
