Weight Loss And Cardiovascular Health: Low Glycemic Index Diet is the best option

We can find many option and opinions about the most effective diet for weight loss and cardiovascular health. Now studies have shown tha a high carbohydrate diet plan based on low glycemic index (GI) foods, according to a study by University of Sydney researchers is probably the best option to consider.

We can find the result of a trial, published in the most recent issue of Archives of Internal Medicine, the world’s randomised, controlled trial compared the relative effects on weight loss and cardiovascular risk of low GI and high-protein diets.

Undertaken by Professor Jennie Brand-Miller and Joanna McMillan-Price from the University of Sydney Human Nutrition Unit, the findings show that there is no ‘one diet fits all’ solution, and although both high protein and low GI diets will help you to shed fat. However, it did show that a diet containing low GI carbohydrate significantly reduces your risk of heart disease.

The trial led by Professor Joanna McMillan-Price witch has enrolled 129 overweight or obese young adults  randomly assigned them to one of four reduced calorie (aged 18-40 years), with a reduced fat diets over a 12 week period. Two of the diets were high-carbohydrate diets and the other two high in protein. One of each diet had a high GI and the other diet had a low GI.

Between the two high-carbohydrate diets, it was incredible to find a so big difference between those diets : lowering the glycemic index doubled fat loss – and moreover this effect was strongest in women.
Participants on the high-protein diet program as shown that a high GI diet was equally effective for fat loss as the high carbohydrate, low GI diet, the two diet had diverse effects on LDL (bad) cholesterol.

It is important to notice that the high protein diet, high-GI group showed increased levels of LDL or ‘bad’ cholesterol, while there were significant reductions in those on the high carbohydrate, low-GI diet. However those on the high-protein, low GI diet did not experience the same rise in total LDL cholesterol suggesting the importance of low GI foods alongside a high meat intake.

Joanna McMillan-Price explain that the findings suggest that dietary glycemic load, and not just overall energy intake influences weight loss and postprandial glycaemia (blood sugar levels after eating).

“We found that moderate reductions in glycemic load appear to increase the rate of body fat loss, particularly in women. Diets based on low-glycemic index, whole grain products, tend to be better for the heart, maximising cardiovascular risk reduction – particularly if protein intake is high,” said Joanna McMillan-Price.

The conclusion is that the most effective diet for weight loss and cardiovascular health is a high carbohydrate plan based on low glycemic index (GI) foods, according to a study by University of Sydney researchers.
