My suggestion is eat more vegetables and drop the packaged, processed snacks and protein shakes altogether. You are no longer healing from surgery or dropping a ton of weight quickly, so you don't need 120g protein, or even 100g anymore. If you can eat 3oz chicken breast twice a day, plus a serving of Greek yogurt and fruit for breakfast, you've hit your protein needs and then some. Get your protein from lean meat, beans, nuts, and seeds (not as much from dairy). Have a leafy or non-starchy vegetable at every meal. Eat fruit for dessert and raw veggies and nuts for snack.
