Actually, it may very well help those people.

Losing weight is hard because it can be incredibly difficult to "just eat less" by the right amount.

If you "eat less" too little, you won't lose weight. While if you "eat less" too much, your health suffers and willpower becomes too difficult.

And counting calories doesn't work well if your calorie needs vary per-day, which nearly everyone's does -- how much did you walk, what temperature were the rooms you were in, etc.

The idea is that real time glucose information will allow you to "eat just right" -- never eating so little that willpower becomes an issue, but never so much that you gain weight (or fail to lose weight).

You shouldn't be so dismissive of the idea.
