Stress. Lack of sleep. An extra scoop (or carton) of ice cream.
The reasons for weight gain are numerous, compounding and complex. But one thing’s for certain: more of us have succumbed to them and the corresponding pounds. In 2012, 69 percent of American adults, 20 and older, were either overweight or obese, according to data from the Centers for Disease Control and Prevention (CDC).
As people around the globe struggle to control their weight, dietary supplement companies are making big gains. Vitamins and supplements aimed at weight loss recorded nearly US $780 million in sales in 2013a whopping 16-percent increase from the previous year.
From the Dr. Mehmet Oz-endorsed raspberry ketones to the old standby protein, key weight management ingredients are scientifically proven to help stave cravings and shed pounds.
“Weight management via natural ingredients is a broad and promisingalbeit sometimes confusingcategory because of the variety of different mechanisms that are related to the energy management component of weight loss," said Barbara Davis, medical and scientific affairs director, PLT Health Solutions.
The four mechanisms, Davis explained, include:
· Controlling energy intake (i.e., appetite modification)
· Controlling substrate availability (i.e., blocking the absorption of dietary fats)
· Controlling fat reserves (i.e., modulation of lipolysis and lipogensis)
· Controlling energy expenditure (i.e., increasing thermogenesis)
Countless efficacious ingredients fall into oneor moreof the above four categories. Read more about them in the feature “Weighing the Research" in INSIDER’s Weight Management Digital Issue.
