Weight Loss Alarming Statistics
Achieving and/or maintaining a healthy weight is the new Holy Grail, so the desire for some adjunctive assistance in the usual quest to lower caloric intake (eat less), increase caloric burn (exercise), and improve the overall diet is unlikely to wane. The International Food Information Council (IFIC) stated the majority of Americans report they are concerned about their weight, and are trying to either lose pounds or stay the same weight. However, they also noted taste and convenience still trump healthfulness in food selection, and many Americans are not savvy when it comes to the science of calorie balance and management.
In fact, despite all the attention obesity and related health problems have garnered, and all the diets undertaken, Americans appear to have yet to stem the growth of its weight problem. According to the Centers for Disease Control and Prevention (CDC) Vital Signs report, obesity rates in numerous states rose in the past decade. The feds had set a goal to bring obesity rates down to 15 percent in 2010, but rates in nine states have actually risen to more than 30 percent; only three states had rates above this level in 2007, and not one state had a rate higher than 30 percent in 2000.
The 2010 disappointment was no huge surprise after CDC released its 2009 National Health Interview Survey, which showed U.S. obesity and diabetes rates are at a 10-year all-time high. The annual prevalence of obesity among U.S. adults aged 20 years and over has gradually increased over time from 19.4 percent in 1997 to 28.0 percent in 2009; the 40 to 59 year old age bracket had the highest obesity rate.
Resveratrol & Weight Loss
Resveratrol also has a dual mechanism in weight management, as a 2010 French study showed supplementation in lemurs during the animals’ body-mass gain season not only increased satiety-related peptides, but also increased RMR by 29 percent and reduced caloric intake by 13 percent, leading to less body mass gain.
The specialty compound 3-acetyl-7-oxo-dehydroepiandrosterone, known as 7-oxo-DHEA, also has a brief, but decorated research history on RMR. A natural substance produced by the adrenal glands, 7-oxo DHEA is known to augment the activity of three thermogenic enzymes: glycerol-3-phosphate dehydrogenase, malic enzyme and fatty acyl CoA oxidase, which leads to increased heat production and utilization of fat stores for energy. In various studies, adults taking 7-oxo-DHEA (as 7-Keto®, from Humanetics) experienced as much as three-times more weight and body fat than subjects taking placebo.51,52 Researchers noted 7-Keto supplementation also increased RMR while the subjects followed a calorie-restricted diet, which normally decreases RMR. Subsequent randomized, double blind, placebo-controlled research revealed 7-keto supplementation increased RMR (1.4 percent) in overweight subjects who undertook a calorie-restricted diet and a washout period before the 7-day intervention.
Where 7-Keto can sometimes be falsely accused of being a “bad” steroid, it has neither anabolic nor androgenic properties. A metabolite of DHEA, it does not convert back to DHEA in the body, and it does not have any receptor in the body to enable any regulation of hormones. Likewise, given the scrutiny stimulants have received, especially in the weight-loss segment, another thermogenic ingredient tries hard to distance itself from the stimulant, ephedra, it has replaced in the weight-control market.
Weight Loss Comments
The weight-loss category often gets a bad rep, with numerous fines, lawsuits and recalls over marketing and quality-control issues. However, there is a ton of good news on weight management nutritional ingredients, especially in the area of proven benefits to various factors and parameters of weight loss, as well as related health issues, including blood sugar health. Research results continue to deliver positive news on the value of such ingredients on fat burning, appetite control, carbohydrate management, satiety and other areas of weight and obesity.
Accumulating some additional weight in middle age and beyond is nothing new, but the alarm has been amplified by the now-infamous swelling obesity rates among children. Market research firm Datamonitor has found two of every five children aged 5 to 13 (40.7 percent) are obese or overweight, a number expected to rise significantly, to 43.4 percent, over the next few years. Increased sedentary lifestyles, high consumption of indulgent junk foods and lack of a consistent healthy diet are all contributors, according to the firm.
