"Carbohydrate oxidation" refers to the process in which carbohydrates, such as sugars and starches found in food, are broken down and converted into energy by our bodies.
Full definition
Furthermore, eating big meals late in the day has been linked to a sluggish metabolic rate,
less carbohydrate oxidation and a decreased glucose tolerance.
The study found that those who consumed a beverage containing 330 mg of caffeine 60 minutes prior to exercise experienced a higher rate of fat oxidation during that workout session, accompanied by a lower rate
of carbohydrate oxidation!
A low ratio of fat to
carbohydrate oxidation is a solid predictor of future weight gain.
And at 120 minutes,
carbohydrate oxidation was higher.
To summarize the findings from this study, they found that decreasing carb intake did lead to increased fatty acid oxidation and decreased
carbohydrate oxidation; however, reducing fat intake led to a slightly bigger loss in body fat than the group that restricted carbohydrates.
As insulin increases, fat break.down and oxidation (burning) significantly decreases and eventually «turns off» while this same insulin increase turns up
carbohydrate oxidation.
The limited number of studies available suggest that whilst the infused tea might help to improve relative fat to
carbohydrate oxidation, it has no effect on metabolic rate or energy expenditure.
The diet high in unavailable carbohydrates also resulted in a significantly lower rapid rise in postprandial
carbohydrate oxidation, and the difference in carbohydrate oxidation between diets was inversely correlated with hunger ratings.
While plasma glucose, insulin, and
carbohydrate oxidation did not change significantly, plasma free fatty acid levels rose from 432 ± 31 to 848 ± 135 µEq / liter and were accompanied by significant increases in fat oxidation during the last hour of the test.
