Congratulations for working towards a plant based diet. I am 5 months post op, and it is absolutely doable! As for protein, there are so many options. Let me count some ways....broccoli, beans, legumes, nuts, peanut butter, chia seeds, hemp hearts(omega 3), nutritional yeast, tofu, tempeh, setian, viral wheat gluten, most plant based pastas, quinoa, sprouted grains, oats, nut butters...ooh boy! That was a lot 🤣😂 There really is a lot of options out there. I have started to make my own unmeat crumbles. I didn’t learn this way overnight, but I didn’t get this fat overnight neither. My thinking on this WLS for me, is I took a drastic change to lose the weight, and I took a drastic change to keep it off. I comend anyone who is changing there lifestyle after this surgery. My surgery date was 12-12-19, and I have lost 68 lbs. I am living my best life, and I feel the best I have ever felt!
