I have never fasted well. I’m also on my feet 10 hrs a day for work so maybe that’s part of it, but it was always a struggle for me. PSMF let me eat some pretty satiating food and definitely burn some fat. Meats I stick to on this are chicken breasts, turkey breasts, tuna fish, pork tenderloin, even ham but I trim off the fat. Lots of leafy greens. I make sure to take a multi vitamin and fish oil every day on this diet. Some recipes I make are some egg white bakes in the oven mixing in spinach and meat, I have an egg drop soup made with chicken breasts, broth, egg whites, and some chives, salads with just a touch of balsamic vinegar. I think the hardest part of this is that it can be bland so use your spices liberally. This is definitely not a long term WOE, but used in short bursts (2-3 weeks) it can be a really good tool.
