What do you mean it doesn't work? How do you know?
And no -- your weight on the scale varies drastically with water levels and food in the gut. By up to five pounds. It is useless for figuring out if you can eat another bite of rice.
While glucose levels are literally minute-by-minute. They're fine-grained enough to actually tell you when to eat more and when to not.
I think the point was that it is easier said than done.
Losing weight is simple in theory, you can just eat less. In practice, eating less is very hard for some people. Having real time glucose information isn't going to help those people.
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.
Just as one data point, I have a diabetic friend on insulin and under a doctor's care who was put on a CGM and told by the doctor "if the meter reads 150 or higher, don't eat". Sometimes this meant not eating for a day. He lost 70 lbs in about a year and hugely reduce his insulin use.
