I did it before for weight loss, it worked amazingly, but the weight came back on just as easily. It would have to be a permanent lifestyle change, and I'm not convinced that's safe.

What makes you think that it isn't safe? I guess the other question is what makes you sure that another diet is safe?

It’s a really extreme diet. I would be concerned with the fat intake, the cholesterol intake, and limits on certain fruits and vegetables.

This is true for every diet. If you get gain weight on your current lifestyle, start dieting and go back after you lost it, you'll gain that weight back.

There's no magic pill, if your current lifestyle makes you fat, you need a lifestyle change.

IMO any extremely restrictive diet is not sustainable and therefor not a real, long-term solution for health
