It gets him to lose weight. But if someone else tried it, any number of things could happen.
People are different, whats healthy for one person could kill someone else. Each person has a health system unique to them. Hell I went a week of eating fast food and lost 2 pounds. I'm sure if anyone else tried that they would gain weight.
Its why I don't do diet plans.
Some things are consistent. Each person has different metabolism, but
everyone's bodies obey the first law of thermodynamics. You can't create mass or energy.
So, if you determine
your baseline for how many calories you burn during the day, and you make sure that your intake is, say, 10% less than that, you'll see weight loss. It doesn't mean the exact same diet works for everyone, but the exact same method
does. Matter and energy are neither created nor destroyed.
