I can actually get down on the floor now and GET UP BY MYSELF! This is still quite amazing to me. There is a ton of information about WFPB eating online. Go to You Tube and watch "The Game Changers" and "Forks over Knives." That will give you a good idea. Basically it is WHOLE, unprocessed food. That means food as close to its natural state as possible. Whole grains, not refined grains, for example. No processed sugars, no animal products (that includes dairy and eggs), no processed oils (you use avocados, nuts and seeds and nut butters instead.) LOTS and LOTS of veggies and fruit, plenty of starchy veggies, lots of legumes, whole grains, nuts and seeds, no alcohol, no soda or artificial colors/flavors/chemicals, decreased salt. Many WFPB folks also avoid gluten (wheat, rye, barley) and I am highly sensitive to it, so have already avoided that for years.
I get more than enough protein, tons of fibers and phytonutrients, eat all I want, am never hungry, have tons of energy, and am NEVER sore after workouts. Amazingly, my cholesterol always hovered around 225-235, even after losing over 100 pounds. Once I went WFPB, my cholesterol dropped like a rock to 152 (80 points!!!). My triglycerides and LDL also plummeted. Even with the low total cholesterol, my HDL went up to 80. For me, it is a lifestyle that I will maintain for life. It is change, for sure, but not actually hard to do. Most of my family is making the switch as well. You don't have to go 100%, either. When you look at the areas of the world (the blue zones) where people live to be over 100 and have virtually no cardiac disease, osteoporosis, dementia, cancer, or diabetes, these are all plant based societies. Does this mean they won't eat some fish or cassowary eggs if they find them? No. But animal protein is the exception or reserved for celebrations. They don't eat meat 3 times a day like most of the western world does. I will occasionally eat an egg (my own backyard chickens) or a little wild game meat. (The more I learn about commercially raised cattle, hogs, chickens, turkeys and dairy cows, the more I cannot bring myself to eat these products.)
So there you go - probably more info than you wanted. I started this about 6 months after my surgery as I learned about it and once I was able to eat the volume that is required. I had to rely a bit more on the grains and nuts to keep my calories up so I wouldn't keep losing weight. I used pea protein powder as needed to keep my protein up. I don't need that now, with the increased legumes, tofu, tempeh, and soy/oat milk and yogurt. Now I eat a lot more of the veggies and legumes, and control my weight very easily with decreasing/increasing the grains and nuts. I did gain 8 pounds of COVID weight, but have lost all of it and some extra, just by cutting back a bit on the nuts and grains. It really couldn't be easier!
