You're reccomending a high sugar diet for weight loss.
Yet its nutritional value is nil. How does it benefit? Low starch, high sugar, low fat, decent protein sounds like a diet that would be improved by omitting the sugar.
IIRC, although your body can run on just the glucose it gets by breaking down fat, it is less efficient. In my own experience this shows up as a negative effect on mood -- which makes me more likely to want to eat (and binge).
