Why Glycemic Load Matters More Than Glycemic IndexGlycemic index and blood sugar impact -
Lowering the GI of conventional energy-restricted, low-fat diets was proven to be more effective to reduce postpartum body weight and waist and hip circumferences and prevent type 2 diabetes mellitus in women with prior gestational diabetes mellitus Yet, the consumption of a low-GL diet increased HDL - cholesterol and decreased triglyceride concentrations significantly more than the low-fat diet, but LDL -cholesterol concentration was significantly more reduced with the low-fat than low-GI diet Weight loss with each diet was equivalent ~4 kg.
Both interventions similarly reduced triglycerides, C-reactive protein CRP , and fasting insulin , and increased HDL-cholesterol. Yet, the reduction in waist and hip circumferences was greater with the low-fat diet, while blood pressure was significantly more reduced with the low-GL diet Additionally, the low-GI diet improved fasting insulin concentration, β-cell function, and insulin resistance better than the low-fat diet.
None of the diets modulated hunger or satiety or affected biomarkers of endothelial function or inflammation. Finally, no significant differences were observed in low- compared to high-GL diets regarding weight loss and insulin metabolism It has been suggested that the consumption of low-GI foods delayed the return of hunger, decreased subsequent food intake, and increased satiety when compared to high-GI foods The effect of isocaloric low- and high-GI test meals on the activity of brain regions controlling appetite and eating behavior was evaluated in a small randomized , blinded, cross-over study in 12 overweight or obese men During the postprandial period, blood glucose and insulin rose higher after the high-GI meal than after the low-GI meal.
In addition, in response to the excess insulin secretion, blood glucose dropped below fasting concentrations three to five hours after high-GI meal consumption. Cerebral blood flow was significantly higher four hours after ingestion of the high-GI meal compared to a low-GI meal in a specific region of the striatum right nucleus accumbens associated with food intake reward and craving.
If the data suggested that consuming low- rather than high-GI foods may help restrain overeating and protect against weight gain, this has not yet been confirmed in long-term randomized controlled trials. However, the dietary interventions only achieved a modest difference in GI ~5 units between high- and low-GI diets such that the effect of GI in weight maintenance remained unknown.

About the glycaemic index GI Digesting and absorbing carbohydrates The glycaemic index GI Glycaemic load GL GI and exercise Using the GI as a guide to healthy eating Choosing between high and low GI foods Where to get help. About the glycaemic index GI Foods and drinks provide our body with energy in the form of carbohydrates, fat , protein and alcohol.
Digesting and absorbing carbohydrates The digestive system breaks down carbohydrates in foods and drinks into simple sugars, mainly glucose. The glycaemic index GI The glycaemic index GI is a way of ranking carbohydrate-containing foods based on how slowly or quickly they are digested and increase blood glucose levels over a period of time — usually 2 hours.
These ranges, along with some example foods, include: low GI less than 55 — examples include soy products, beans, fruit, milk, pasta, grainy bread, porridge oats and lentils medium GI 55 to 70 — examples include orange juice, honey, basmati rice and wholemeal bread high GI greater than 70 — examples include potatoes, white bread and short-grain rice.
Glycaemic load GL The amount of the carbohydrate-containing food you eat affects your blood glucose levels. Calculating glycaemic load GL The GL calculation is: GI x the amount of carbohydrates in grams in a serving of food ÷ GI and exercise Eating low GI foods 2 hours before endurance events, such as long-distance running, may improve exercise capacity.
Using the GI as a guide to healthy eating The GI can be considered when choosing foods and drinks consistent with the Australian Guide to Healthy Eating External Link , but there are limitations. Choosing between high and low GI foods The best carbohydrate food to eat varies depending on the person and situation.

Several factors affect the glycemic Glycemic index and blood sugar impact of inpact food, anf the ripeness, nutrient composition, and cooking method. Several factors influence the glycemic index of a food, including its nutrient composition, cooking method, ripeness, and the amount of processing it has undergone. This article takes a closer look at the glycemic index, including what it is, how it can affect your health, and how to use it. The glycemic index GI is a value used to measure how much specific foods increase blood sugar levels. As explained Glycemic index and blood sugar impact our previous blog post, sugar is a carbohydrate used by your body for fuel. To impacr, the blood sugar also known Anti-bacterial mouthwash glucose that is Hydration for recreational sports throughout idex bodies impavt in part from the boood that we consume. The Glycemic Index GI measures how quickly carbohydrates in a food cause blood sugar levels to rise after eating and how quickly the carbohydrates convert to glucose in your body. The GI system compares all foods to pure glucose or white breadwhich causes a rapid spike in blood glucose levels and has a Glycemic Index value of High-glycemic foods digest and absorb into the bloodstream quickly, which causes large, rapid changes in blood sugar levels.
