GI becomes irrelevant once you eat more than once every 24 hours, which for most people is the norm. [1]

- dragonwriter 11y agoThat's less true for people with any of many conditions impacting to carbohydrate metabolism, pretty much all of which are overrepresented among the overweight.
- dylanjermiah 11y agoI've added the source, he talks about that.
- rb2k_ 11y agoI have no idea where you got that information from, but from what I know this is simply not true?

- msandford 11y agoI would respectfully disagree. There are a great many foods which can have substantial short-term effects on blood sugar well outside the range that the body has the capability to process effectively. This is a classic example of an underdamped control system leading to oscillations. It happens because the bandwidth of the control system isn't sufficient for the bandwidth of the input. As an engineer if I faced this problem I typically would try and increase the bandwidth of the control system to solve the problem. But that's not really an option in the human body (yet) so the only real solution is to try and control the bandwidth of the input. http://en.wikipedia.org/wiki/Control_system#/media/File:Second_order_transfer_function.svg http://en.wikipedia.org/wiki/Control_system#/media/File:Seco... The more you control the input bandwidth (excess sugars) the less you're going to end up with oscillations and I suspect that those oscillations are what help people really put on weight. Eat too much sugar, it gets stored into fat and a sugar crash. That sugar crash presents as "false" hunger, so you eat again. Probably you eat too much sugar again, and so the cycle repeats. There's probably a lot of variation from human to human on the insulin control system bandwidth, and there's a lot of variation in the diet different people choose to eat. So if one person has high bandwidth and generally good diet, perhaps it only makes a difference like you've suggested. Someone with low bandwidth and a terrible diet might see substantial improvements by doing nothing more than cutting large quantities of high GI food from their diet.
