I went full Vegan last year and with a little research and experimentation I found several protein and carb sources that are easy to balance throughout the day to create any diet plan you want: 20%fat-55%carb-35% protein, 30%fat-40%carb-30%protein, etc. I am currently on 20%fat, 54% carb, 26%protein. I would suggest considering going organic as well to eliminate as much processed food as possible.
The following foods make up my weekly diet:
Grains (oatmeal, quinoa, buckwheat, wild rice, long grain brown rice, )
Veggies (spinach, asparagus, yellow squash, broccoli, cauliflower, corn, cucumber, onion, peas, bell peppers, )
Beans/Legumes: (black beans, kidney beans, chick peas, peanuts, lentils, )
Seeds (chia, hemp, sunflower, pumpkin, flax, )
Fruits (orange juice, mandarin oranges, grapes, blueberries, cranberries, bananas, avocado, tomato)
Nuts (almonds, pistachios, almond butter, cashew butter, )
Meal bars (odwalla banana nut, odwalla orange cranberry, zing orange cranberry, zing coconut crunch, )
Protein powder (Garden of Life-RAW)
I avoid soy but will eat these if I don't have any other protein source: (edamame, soy nuts, tofu, )
All of these are low glycemic index foods meaning that you can keep glucose steady throughout the day.
Spend a little time googling different food sources for calorie, macronutrient, micronutrient, and glycemic load/index. I believe you will feel better and are likely to eat an even more balanced meal plan due to the attention required to your food and meal choices.
I'll be glad to share a full meal plan with macronutrient info if that would be helpful to you.
Best of luck and success to you!
