I'd never be able to eat every 3 hours because I'm diabetic & a recovering binge eater. I'm better off eating less often. But that said, mixing it up does seem to spark weight loss. I'll be not losing, decide to eat supper (which I usually skip) & I'm suddenly losing again. But if I keep eating 3 meals my blood sugar goes up. So it's a once in a while thing.

And has been said - we're all different! Funny how we can have the same basic human body, yet our needs are so different.
