This reminds me slightly of Tim Ferris' "The 4 Hour Body". Has anyone had any real experience with his suggested diets? I find eating consistent and similar meals is cheaper and healthier.
There are many ways to eat slow carb without strictly following the 4HB diet. For example, Tim Ferris says to stay away from anything that is "white, or can be made to be white." He's talking mostly about wheat, flour, and pasta, but also includes brown rice. Brown rice is an excellent slow carb so it shouldn't be excluded. There are a lot of great grains that are slow carbs like buckwheat, quinoa, wild rice, steel cut oats, etc, that won't make you gain weight and are good balanced carbs.
My experience is that you can do the 4HB diet for a month or two and lose some weight, but think about it - do you want to eat beans every meal for the rest of your life? It's not a sustainable diet that you can stick with for a long time, and that's what matters. In the end, you need a healthy diet that you can stick with for an extended period of time, or you're just going to gain the weight back.
Stick with slow carbs (all the ones I mentioned above), nuts, fruits, vegetables, eggs, and lean meats, and you'll be fine. Stay away from fast carbs, sugars, and foods with a high glycemic index and get some variety in your diet. Eat breakfast every day with protein in it.
Another thing that doesn't work with Tim Ferris' diet is the "no fruit" rule. Fruit is not that bad. Most fruit has a low glycemic index, although some like watermelon is not that good for you (high GI). Completely excluding any fruit from your diet is probably not healthy long term.
