First introduced in the 1980s, Calorad gained popularity as a dietary supplement advertised to cause weight loss while sleeping. That particular claim is no longer used in the marketing materials for this collagen-based supplement, although among Calorad's claims are that it can simultaneously promote muscle growth while causing weight loss.
Calorad
According to Asantae, the company that “exclusively offers” Calorad Advanced, the supplement is an “amazingly powerful” weight-loss aid. The product will purportedly restore your body to its "natural collagen base," which will then cause both your appetite and food cravings to lessen. Other Calorad claims include its ability to "knock off" belly fat and slow down your body’s loss of lean muscle tissue, which naturally diminishes as you get older.
Collagen
The primary ingredients in Calorad, as listed by clinical exercise physiologist William Sukala on The Original Diet Review Site, are hydrolyzed collagen and aloe vera. This hydrolyzed collagen, says Sukala, is essentially a form of protein to the protein your body would take in if you ate an egg or a can of tuna. When taken orally, aloe vera is a natural laxative that will cause an increase in the frequency of bowel movements.
Before Bed
Dieters are instructed to take Calorad on an empty stomach, three hours before going to sleep. According to product information, the collagen in Calorad is formatted with a “cold enzymatic” process that makes the protein more “bioavailable” and thus more easily absorbed into the body. According to information on the website of J&B's Health Center for Wellness, Calorad begins working during your first hour and a half of sleep, known as the Delta mode. During this time, not only does the collagen cause your body to build lean muscle, it uses your stored fat as energy to fuel this process. Essentially, by simply drinking Calorad and going to sleep, you'll wake up with more lean muscle and less fat.
Veracity of Claims
As Sukala points out on The Original Diet Review Site, there has been no formal research published in any peer-reviewed scientific journals to support any of Calorad’s claims -- nothing beyond unproven anecdotes and product testimonials. In addition, Sukala explains that it's highly unlikely that collagen would actually cause an increase in lean muscle mass, unless you also placed additional physical demands on your muscles, such as weight-lifting or resistance training, that would result in muscle growth.
