I dont eat gluten so i cant speak on that but .. since you just started out im sure you feel great but its almost impossible to get fat on a vegan diet if you train. Make sure your eating enough because people feel amazing starting out on the diet but start to feel the effects of lacking nutrition later on. Make sure you eat nuts, grains, quinoa, sweet potatoes, avocados, and overall a good variety of foods. try new fruits and veggies, explore health food stores and look in to some supplements as well. Sunwarrior protein may interest you. hope this helps
