If they can it'll be huge. Maybe even Ozempic-huge. There's a theory of weight loss that you can objectively manage your weight by never allowing your blood sugar to go over a certain level.
That doesn't work, even if it were true. You can also manage your weight by never allowing the weight on the scale to go over a certain level.
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.
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.
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.
We're not talking about people with underlying health conditions. Exceptions don't invalidate a general principle.
> You’re suggesting 20 calories can make you obese because it raises blood glucose lol!
Nothing "lol" about it. An extra 20 calories, 20 times a day, every day for months and years, above your caloric needs, is yes quite likely to make you obese. How else do you think most people get obese?
> fat... will not spike your blood glucose until 5-12 hours later
And you can become aware of those patterns. You will know, for example, not to eat anything else during that window. Or learn to eat fat in gradual amounts, rather than large amounts in a single sitting.
> Blood glucose is VERY important but not predictive of weight.
You seem quite confident about that. You're also quite possibly wrong. The underlying logic is pretty sound: we gain weight when our blood sugar goes up and therefore our insulin goes up to remove the sugar from the bloodstream and, eventually, store it as fat.
I like this post because it assumes that humans don’t use sugar for energy. It is all stored as fat because the human body is a closed system that does not burn calories.
Also I like “I see you said 20, obviously you mean 20 times that”
