Disclaimer: I've just briefly scanned over this diet.
So pick any of these 'fad diets' going around and if you stick to them they'll work. For the mass majority of people, they work for one reason. That reason is calories. Whether it's keto, paleo, whole 30, atkins, shakeology, smoothies, blah blah blah they're all the same real concept when it comes down to weight loss. The most important thing about any of them is that you stick to it. Don't get caught up in the fancy nutrition terminology with their superfoods and organic grass-fed potatoes. You don't need to worry about reprogramming your body to burn animal fats. The latest trendy diet doesn't have a sudden discovery of a nutritional secret. It's simple....if you eat less calories then you expend, you will lose weight. The challenging part is finding which diet is realistic and sustainable permanently for you. Obviously no matter which one you choose you will have to make changes from what's normal for you, but some are just a matter of eating less of what you normally eat.
While I'm ranting, please don't mistake weight loss for nutrition. They are not at all the same thing. Just because you're losing weight does not mean you're eating healthy and nutritious. If your main goal is weight loss, you can eat only twinkies and as long as you're consuming less calories than you're burning you will lose weight.
If I had to make a recommendation for the average person to pursue their weight loss venture it would be this:
1. Try Whole 30. Don't buy any books...google it a little bit and get the gist of it. The basic concept is it locks you in to making better food choices. This is a great first step and if you can make yourself eat healthy foods for a month, you will feel better, look better, and have a good foundation for making good food choices. Stay off the scale. You will be losing weight, but if you weigh yourself more than once a week you're just asking for a big punch in your motivational balls. Also, don't try to emulate the crap you're not allowed to eat. There's no reason to spend $20 on a package of almond flour so you can make fake pizza crust and be disappointed that you're not eating pizza. Save that for your cheat meal. EVENTUALLY once you have this diet thing down...sure give it a shot. There are actually some decent alternative to bread, cake, and dough out there. You're not ready for that yet. Just eat real food.
2. Download MyFitnessPal. It's a free app that has preprogrammed calorie info for everything you can buy at a grocery store or order from a chain restauraunt. If you're feeling courageous, start tracking some during your whole 30 month. Even if you don't stick to the calorie goals it recommends yet, it will give you a baseline idea of how many calories the things you normally eat actually are.
3. After whole30, keep the same routine (if you like it), but now start adding in one cheat meal (NOT A CHEAT DAY FATTY) once a week. I prefer a dinner cheat meal, because if I do it at breakfast I have a really really hard time eating good the rest of the day. At this point you're basically doing a Paleo or Keto style diet. The hardcore bros might disagree on some technicalities (sweet potatoes), but they're more or less the same concept.
4. Get a food scale (they can be had for $10 on amazon) and start weighing out your meat portions. You can weight veggies too if you want, but they're so low calorie generally that 30 calories here and there isn't going to make a big difference once you get a good guestimate down.
5. You no longer need to follow anyone else's diet plan. Count your calories, drink a beer or two (those are in the app too) and enjoy your life.
