Warning Letter for Weight Loss Products
"Metabo FatBlockerTM" and "Extreme Carb Blocker"


Wade Downs
P.O. Box 1751
Corinth, MS 38835

Dear Mr. Downs:

The Food and Drug Administration (FDA) has reviewed your web sites at the Internet addresses http://www.proper-health.com and http://www.power-plus.org and has concluded that claims on these web sites cause your products "Metabo FatBlockerTM" and "Extreme Carb Blocker" to be misbranded under the Federal Food, Drug, and Cosmetic Act (the Act). You can find the Act and FDA's regulations through links on FDA's Internet home page: http://www.fda.gov.

Under section 403(r)(6) of the Act, dietary supplement labeling may include claims about the supplement's effect on the structure or function of the human body (structure/function claims), provided that certain requirements are met. 21 U.S.C. § 343(r)(6)(A). One of these requirements is that the manufacturer of a dietary supplement bearing a "structure/function" claim must have substantiation that the claim is truthful and not misleading. 21 U.S.C. § 343(r)(6)(B).

The labeling of Metabo FatBlockerTM and Extreme Carb Blocker bears structure/function claims that include the following:

  • Metabo Fat Blocker:

    o "[C]an bind to dietary fat and provide a feeling of fullness - thus suppressing the appetite."
    o "Binds with the fat you eat - reducing the amount of fat you absorb from your meal."

  • Extreme Carb Blocker:

    o "Extreme Carb Blocker helps you reduce starch calories by blocking alpha amylase.... the undigested starch and its calories simply pass through the body undigested."
    o "Phaseolus Vulgaris [an ingredient in Extreme Carb Blocker] . . . is a starch blocker that has been clinically shown to neutralize up to 66 percent of the starch consumed in a meal."
    o "Blocks carb absorption . . .
    o "Helps reduce sugar cravings"
    o "Controls carb cravings "

We have reviewed these claims and have concluded that they are not supported by reliable scientific evidence. Because these claims lack substantiation, they are false or misleading, and cause your products to be misbranded within the meaning of sections 403(a)(1) and 403(r)(6)(B) of the Act. 21 U.S.C. § 343(a)(1), (r)(6)(B). It is a violation of section 301(a) of the Act to introduce or deliver for introduction into interstate commerce any food, including a dietary supplement, that is misbranded. 21 U.S.C. § 331(a).

This letter is not an all-inclusive review of your web site and the products that your firm markets. It is your responsibility to ensure that all products marketed by your firm comply with the Act and its implementing regulations.

The Act authorizes injunctions against manufacturers and distributors of illegal products and seizure of such products. 21 U.S.C. §§ 332, 334. You should take prompt action to correct any violations, including the violations identified in this letter. Failure to do so may result in enforcement action without further notice.

If you have scientific evidence which you believe substantiates that your claims for Metabo FatBlockerTM and Extreme Carb Blocker are truthful and not misleading, please provide it to us within fifteen (15) working days of receipt of this letter. Alternatively, please advise this office, in writing and within fifteen working days of receipt of this letter, of the specific steps that you have taken to correct the noted violations and to ensure that similar violations do not occur in the future. If corrective action cannot be completed with fifteen working days, state the reason for the delay and the time within which the corrections will be made.

Your reply should be sent to the attention of Compliance Officer Quyen Tien at the above address.

Sincerely yours,


Joseph R. Baca
