I've just completed Day 7 of the Engine 2 diet, which isn't a diet per se but rather a means of changing one's eating habits.
Engine 2 diet is basically a Vegan diet (consuming anything with a face or mother is forbidden) that was started by the head fireman from a Houston's Fire Engine 2. He persuaded a company of Texan red meat eaters to go Vegan. However, his father (who really devised it while doing heart research) is/was head of the Cleveland Clinic--a top heart hospital in the US, which was founded by his great grandfather. If you're interested to try it out, the book is called The Engine 2 Diet by Rip Esselstyn and there's a website.
Basically, the diet states we've been brainwashed by the meat and dairy industries and the USDA to believe we can only get good protein from animals and their by-products. This is not true as animals get their protein from plants--and meat and dairy are basically not good for us and that living a plant based diet can eliminate and in some cases reverse the damage caused by the western diet. The only vitamin not found in plants--largely as a result of modern day large scale food production--is B12 and that you can get from Nutritional Yeast, which looks like grated Parmesan and can be used in dishes as such.
I'm a meat and chicken eater, love cheese and yogurt and haven't missed any of it so far. The recipes suggested as part of the diet we have so far enjoyed, and the one we found a little bland was easily fixed with additional spices, etc. So far the one I enjoyed best was the Portabello Mushroom burger with sweet potato fries. Major yum-yum. That surprised me.
Real Men can also be Vegans. Who knew.
Report on Week 2 next Sunday.
