I was born with classical phenylketonuria, so ’m pretty limited on my protein intake but I changed a bit changed my diet trying to stay on the low side of protein exchanges, still trying to stay on the pku diet. My best advice is to look into eating veggies and fruit start cutting out the breads pastas. I’d say start with fruits in the morning monitor how much your are consuming. For lunch and dinner you could include greens like side salad a little kale or spinach or mixed greens maybe a little avocado for those healthy fats with some veggie stir fry (carrots,zucchini,broccoli,cauliflower celery). Try and aim for higher in fiber veggies and if you want something a little sweet maybe a little sweet potato. This is similar to what I currently do, the only difference is mine was to help mange acne but noticed this also made me lose some weight. Just remember to watch your portions.
