         Westend S.A., a Luxembourg societe anonyme ("Westend"), hereby
amends, as set forth below, its Statement on Schedule 13D filed with the
Securities and Exchange Commission on March 18, 2004 (the "Statement")
relating to the common stock, no par value, of Weight Watchers International,
Inc., a Virginia corporation (the "Company"). Capitalized terms used herein
that are not otherwise defined shall have the meanings given to them in the
Statement.

Item 5.   Interest in Securities of the Issuer.

The response to Item 5 is amended and restated as follows:

         On March 8, 2006, wholly-owned indirect subsidiaries of Westend sold
an aggregate of 10,000,000 shares of Common Stock at a price per share of
$50.50 pursuant to a registration statement on Form S-3 under the Securities
Act of 1933, as amended.

         As of the date hereof, Artal Holdings Sp. z o.o., Succursale de
Luxembourg was the record owner of 54,265,825 shares, or 54.0%, of the Common
Stock outstanding (based on 100,454,369 shares of Common Stock issued and
outstanding on January 31, 2006 as reported in the Company's Annual Report of
Form 10-K for the year ended December 31, 2005). Artal Holdings Sp. z o.o.,
Succursale de Luxembourg is a subsidiary of Artal Luxembourg S.A., which is a
subsidiary of Artal International S.A., which is a subsidiary of the Artal
Group S.A., which is a subsidiary of the Reporting Person. Consequently, the
Reporting Person may be deemed, for purposes of Section 13(d) of the
Securities Exchange Act of 1934, as amended, to be the beneficial owner of the
shares of Common Stock held of record by Artal Holdings Sp. z o.o.,
Succursale de Luxembourg.

         Except as set forth in this Item 5, to the best knowledge of the
Reporting Person as of the date hereof, the Reporting Person and no other
person described in Item 2 hereof has beneficial ownership of, or has engaged
in any transaction during the past 60 days in, any shares of Common Stock.





                                   SIGNATURE

         After reasonable inquiry and to the best of my knowledge and belief,
I certify that the information set forth in this statement is true, complete
and correct.

                                           WESTEND S.A.
