Low-glycemic diet best for weight management

Low-glycemic diet best for weight management

In response to the recent JAMA study, Canadian company offers an ingredient aimed at converting high-GI meals into low-GI meals.

A new study published in the Journal of the American Medical Association (JAMA) found that low-glycemic index (GI) diets are superior to low-fat and low-carb diets when it comes to weight maintenance. Science-driven Canadian company innoVactiv offers a revolutionary ingredient that takes the new findings a big step further, essentially converting high-GI meals into low-GI meals.

As dieticians and nutritionists will attest, the biggest challenge in the fight against obesity is not losing weight; it’s keeping it off. After losing 10 percent of their body weight, five out of six people will regain that lost weight in less than a year. The statistics are daunting, but challenging odds are exactly what spur on a company like innoVactiv. Their proprietary ingredient InSea2® is the only ingredient on the market today capable of slowing down both starch and table sugar digestion and assimilation. In essence, using InSea2® will reduce the glycemic response elicited by a starch meal by 48 percent and a table sugar meal by 39 percent, making them function as having a lower GI.

In the JAMA research study, Dr. Ebbeling and her group recruited overweight adults and submitted them to a run-in period comprised of a weight-loss phase (to induce 10 to 15 percent weight loss) and a weight-stabilization phase. Then, subjects were submitted to a weight-maintenance phase with low-fat, low-carb and low-GI diets according to a random sequence.

The results found the low-GI diet to be most beneficial. The low-GI diet induced a comparatively small drop in resting metabolic rate and had favorable impacts on the overall metabolism when looking at inflammation and stress markers, as well as hormonal homeostasis. As a comparison, the low-fat diet induced the greater decline in resting metabolic rate and total energy expenditure (meaning people on such diet may regain their weight more quickly), in addition to an increase in insulin resistance and an unhealthy blood lipid pattern. The low-carb diet (Atkins diet) was the best at preserving resting metabolic rate, but it also increased C-Reactive Protein (a marker of inflammation) and cortisol levels (a stress hormone) at the highest level. Researchers thus concluded that low-GI diets were preferable choices for weight maintenance, and may also be easier to comply with on the long term than low-carb or low-fat diets.

“Far too many people succumb to cycles of yo-yo dieting,” said Jocelyn Bérubé, Scientific Director at innoVactiv. “They spend half of their life dieting, and the other half regaining that lost weight. With InSea2®, we offer formulators a new tool to develop products like healthy treats, functional drinks or dietary supplements that will cater to this population and help them maintain their blood glucose and insulin levels in an optimal state for prolonged weight control.”

One formulation strategy would be to combine InSea2® with other ingredients having weight loss or weight-management effects, such as a satiety inducer. Such combination has already proven effective in clinical trial, where the formula was able to prevent the rebound effect on appetite and ingested calories after the end of the diet period, and induce significant weight loss. InSea2® can be easily delivered in capsules, tablets, drinks and as part of functional foods.
