Calorad

Calorad is a liquid protein weight loss supplement which was first introduced to the US and Canadian marketplace in 1984. It has been advertised on both television and radio. Calorad is manufactured by NutriDiem and is marketed by several companies including Essentially Yours Industries and Nysante, all of which are headquartered in Canada.

Calorad is a liquid dietary supplement composed primarily of 3,000 mg (3 grams) of Type II hydrolyzed collagen (hydrolysate) from either beef (bovine) or tuna (marine) sources and 8 mg of aloe vera, both of which are listed as active ingredients. The supplement label lists that it is fat-free and carbohydrate-free and that 1 serving (1/2 ounce) provides 3 grams of protein and 10 calories. It also comes in a Kosher formulation (marine). The primary claim made for the product is that regular use causes weight loss without loss of lean muscle mass. While weight loss and body fat reduction can be achieved simply by following the labeled instruction to avoid eating within three hours prior to sleep, most individuals following this regimen alone are not successful in accomplishing long-term weight loss.

Although the manufacturer does not make claims for Calorad in the treatment or cure of disease, the manufacturer does cite published clinical trials conducted with Type II hydrolyzed collagen (collagen hydrolysate), the primary ingredient in Calorad.

The manufacturer claims that 40% of subjects will lose weight within 1 month, 75% after 2 months and 87% after 3 months. The distributors of the product offer a 30-day satisfaction guarantee. In support of these claims, the distributing companies cite a clinical study of Calorad (also unpublished and non-peer reviewed) by Joel B. Lao. Lao is a Doctor of Internal Medicine, and medical consultant in the Philippines who studied the effects of Calorad and its effect on overweight and/or obese individuals. The subjects included 50 overweight or obese individuals who were observed over a 90-day period. One bottle of Calorad was provided to each of the subjects every month for a 3-month period. In month 1, the average weight loss was 5.7 pounds. By month 3, subjects had an average reduction of 10 pounds, and an average inch loss at the waist of 3 inches.

The claim that Calorad builds or maintains lean muscle mass without any increasing demand on the user's musculature is based upon an unpublished and non-peer reviewed study by Davis "et al". in which 300 subjects between the ages of 17-77 years, were followed for 1 year and most of whom lost weight (an average of 3.75 pounds per month) but maintained lean muscle mass. [ [http://www.nutritionadvisor.com/Rena_Davis_Calorad_Study.pdf Rena Davis Calorad Study] ] Davis states: "We also found that in the entire group, less than 0.6, or less than 1 per cent, had any loss of lean muscle mass. And 36 per cent of the group actually gained lean muscle mass during that time."

One of the marketing companies, Essentially Yours, states that most subjects on a weight loss regimen lose lean muscle mass along with fat and water weight, so that maintaining lean muscle mass is a benefit seen with Calorad users.

When first introduced, the manufacturer claimed that Calorad could cause the user to "lose weight while you sleep", repair joints, and prevent or reduce the symptoms of arthritis. The manufacturer has since dropped these claims because they are "medical treatment claims" and require a drug treatment classification approved by the FDA, and are usually only granted following submission of large clinical trials similar to those conducted by pharmaceutical companies in substantiation of these claims. Neither the manufacturer (Nutridiem) or the distributing companies (EYI) have conducted this type of rigorous trial on Calorad in support of such claims. The manufacturer and distributing companies have replaced these claims with the current claim that Calorad "promotes sleep and improves the health and appearance of hair, nails and skin" (all of which are not medical treatment claims).

Calorad, like all nutritional supplements, has not been evaluated by the US Food and Drug Administration, and all marketing materials related to the product carry a disclaimer to the effect that it is nothing more than "a food supplement and is not intended to diagnose, treat, cure, or prevent any disease."
