I'm vegan but I have no problem eating 2000+ calories if I don't watch it.
Typical day for me:
Breakfast:Smoothie with protein powder, frozen berries, unsweetened almond milk and flax seed meal.
Snack: Chia pudding with unsweetened almond milk, pumpkin puree and chia seeds.
Lunch: Large salad with lots of veggies, some beans, some quinoa and some olive oil/balsamic vinegar. Maybe a piece of fruit as well.
Dinner: Quinoa (or other grain) with a tempeh/tofu or bean dish. Steamed greens on the side
I usually eat around 1500-1600 calories.
You can't out-exercise poor eating habits.
