A team of researchers at the University of Nottingham studied the effects of breakfasts containing low-glycemic index or a high-glycemic index foods on fat burning power whilst at rest and walking exercise in non-dieting, healthy, sedentary women.
The breakfasts provided were muesli with milk and canned fruit with a little apple juice (low GI) or cornflakes and milk, with white bread and jam and a carbonated fizzy drink (high GI). The breakfasts provided either 3.5g fiber (low GI) or 1.5g fiber (high GI).
After walking 3 hours later (for 60 minutes) the women were found to burn twice as much fat per hour after the low GI breakfast compared to the high GI breakfast.
In addition, after eating an identical lunch, on the days where the women ate the low-GI breakfast they also reported feeling fuller than on days where they had previously eaten the high GI breakfast.
These are early findings, from a small study, but they highlight the point that the favored breakfast of cereal and fruit reported by successful weight maintainers who are members of the weight registry, reported in my previous post, has scientific merit as well as ‘statistical’ merit from the members of the registry.
Footnote: The Glycemic Index is a measure of how much a food stuff makes the blood sugar levels rise after consumption.
Foods that are broken down rapidly releasing glucose into the bloodstraem have a high GI, those that are digested more slowly and release glucose into the bloodstream gradually, have a low GI.
The higher the rise the in blood sugar the more problematic the food is for diabetics who have difficulty with glucose metabolism.
The concept has been applied to modern diets in general, which tend to be high in refined carbohydrates and create rapid spikes in blood sugar levels compared to unprocessed foods (this is a general brief summary).
The graph below helps to see the picture in a more visual manner.
Hope this helps in your quest for a slimmer you,
Take care,
