Actually if people would *read the books* and follow the plans as written the high protein diet is healthy. It's all the tweaking people do to speed up the weight loss that screws things up. People aren't supposed to gorge on fatty meats just eat enough to satisfy hunger. As time goes on they are supposed to add in the healthy whole carbs like veggies, fruit, nuts, beans, whole grains until they stop losing weight and then adjust down to where to where they start losing again. It's really a whole foods diet.
You can't expect the drive-by media to actually read a book and understand the diet they are criticizing! And then for scientists to actually read the book rather than the drive-by media's summary of it!
