It's the latest fad diet. It's probably fine for people who gained a small amount of weight recently from a very specific event and just need to take off those few pounds and go back to their normal routine. If you've been overweight for more than a few months, though, it's probably not effective or healthy. The diet is based on the idea that you eat "normally" on the other 5 days, but that's not the way most people will actually do it. Those of us who have long-term weight issues have them largely because we balance low-calorie and high-calorie days naturally. If we eat very little one day, we instinctively make up for it the next, but if we eat high calories one day, we don't instinctively eat less the next. In earlier times of human history, that would have made us the healthy, strong ones, but now it makes us fat.
One of the problems in weight loss medicine is that a lot of the "experts" are people who either never had a weight issue themselves or only had one briefly-- they had to lose baby weight or they gained 30 pounds in medical school or something. Then they assume that everyone else's weight problems are the same as theirs and that their approach will work for people whose problem is actually quite different. They don't separate overweight into acute vs chronic the way they do with other health issues.
So if you're acutely (suddenly) overweight, this might work. If you're chronically overweight (it's been going on for years,) an approach that has you counting calories or otherwise keeping track of what you eat at all times is probably going to work MUCH better.
