i actually lived with a fat vegan who never ate junk food/processed sugar. he just overate every healthy thing he made and couldn't understand why he was fat. he was constantly eating. even if you make beans and rice and eat vegetables with it, if you eat enough portions for a whole family, and then eat 15 pieces of fruit a day, and make a 40oz smoothie with coconut milk and berries and bananas twice a day, and make your own peanut butter and eat it by the jar as a 'snack'... i could go on and on. he had rich parents and spent like $600 on groceries for himself every month.
