I'm vegan, so I stick to a dairy- and meat-free diet. I've finally discovered as an adult, though, that while I love carbs, my body hates them. I retain weight and get very bloaty with starchy carbs (bread, pasta, grains), so I've recently been eating a small serving protein (tempeh, tofu, or beans), with a half-plate full of veggies and some type of fruit for dessert.
Pastries (cookies, cakes, anything sugar-laden) is definitely another downfall, so I've had to jump off that bandwagon as well and try to stick to a piece of chocolate as my after dinner "treat".
