                                 PROXY STATEMENT
                     FOR 2006 ANNUAL MEETING OF STOCKHOLDERS
                        TO BE HELD ON September 8th, 2006

                               GENERAL INFORMATION

      This proxy statement is furnished in connection with the solicitation by
the board of directors of Medifast, Inc. (the "Company") of proxies to be voted
at its annual meeting of stockholders on Friday September 8, 2006, to be held at
10:00 a.m., local time, at The Roland E. Powell Convention Center. The
Convention Center is located at 4001 Coastal Highway, Ocean City, MD 21842 and
at any adjournments or postponements, for the purposes set forth in the
accompanying notice of the meeting. This proxy statement, the foregoing notice
and the enclosed proxy card will first be mailed to stockholders entitled to
vote on or about July 21, 2006.

      Sending a signed proxy will not affect a stockholder's right to attend the
meeting and vote in person because the proxy is revocable. Any stockholder
giving a proxy has the power to revoke it by returning to the Company prior to
the annual meeting a proxy bearing a later date, by attending the meeting and
voting in person or by otherwise giving written notice to the Secretary of the
Company at any time before the proxy is exercised.

      When your proxy card is returned properly signed, those shares will be
voted in accordance with your instructions. The board knows of no matters that
are likely to be brought before the meeting, other than the matters specifically
referred to in the notice of the meeting. If any other matters properly come
before the meeting, the persons named in the enclosed proxy, or their duly
appointed substitutes acting at the meeting, will be authorized to vote or
otherwise act with their judgment in those matters. In the absence of
instructions, the shares represented at the meeting by the enclosed proxy will
be voted "FOR" the nominees for director and "FOR" the ratification of the
selection of Bagell, Josephs, Levine & Company, L.L.C. as the Company's
independent auditors for the year ending December 31, 2006.

                             SOLICITATION OF PROXIES

      The expense of this proxy solicitation will be borne by the Company. In
addition to solicitation by mail, proxies may be solicited in person or by
telephone or telecopy by officers or other regular employees of the Company,
without additional compensation to those officers and other employees. The
Company is required to pay, upon request, the reasonable expenses incurred by
record holders of common stock, who are brokers, dealers, banks, voting trustees
or other nominees for mailing proxy material and annual stockholder reports to
any beneficial owners of common stock they hold of record.

                            QUORUM AND VOTING RIGHTS

      Holders of record of the Company's common stock, as of the close of
business on July 14, 2006, the record date, will be entitled to notice and to
vote at the meeting and at any adjournments. Holders of shares of common stock
are entitled to vote on all matters brought before the meeting.

      As of June 13, 2006, there were 13,371,402 shares of Common Stock, par
value $.001 per share (the "Common Stock") issued less 212,494 shares of
treasury stock leaving a total of 13,158,908 shares of common stock outstanding
shares of common stock issued and outstanding entitled to vote on all matters.
Each issued and outstanding share of common stock entitles the holder to one
vote. The presence in person or by proxy of the holders of a majority of the
outstanding common stock is necessary to constitute a quorum at the meeting.
Abstentions will be counted for the purpose of determining whether a quorum is
present at the meeting.


Directors are elected by a plurality vote of shares present at the meeting,
meaning that the director nominee with the most affirmative votes for a
particular slot is elected for that slot. In an uncontested election of
directors, the plurality requirement is not a factor. The holders of common
stock are not entitled to cumulate their votes in the election of directors.
Abstentions will not count as votes cast and will have no effect on the outcome
of this proposal. We expect that brokers will be entitled to vote on this
proposal, but any broker non-vote will have no effect on the outcome of the
proposal.

      The ratification of the board's selection of the Company's auditors and
any other matters brought before the meeting will require the favorable vote of
a majority of the votes cast at the meeting by the holders of stock entitled to
vote at the meeting. Abstentions will not count as votes cast and will have no
effect on the outcome of this proposal. We expect that brokers will be entitled
to vote on this proposal, but any broker non-vote will have no effect on the
outcome of this proposal.

      The Company is not aware of any matter, other than as referred to in this
proxy statement, to be presented at the meeting.

The Company's executive offices are at 11445 Cronhill Drive, Owings Mills,
Maryland 21117 and its telephone number is (410) 581-8042. This proxy statement
and the accompanying proxy are first being distributed to the shareholders of
the Company on or about July 21, 2006.

                     PROPOSAL NO. 1 - ELECTION OF DIRECTORS

      The number of directors in each class is determined by the Board of
Directors and consists of as nearly equal a number of directors as possible.
These directors are classified as Class I, Class II and Class III based on
tenure with the Board of Director's. The term of Class I Directors will expire
in 2007. The term of Class II Directors will expire in 2008. The term for Class
III is up for re-election for a three-year term ending in 2009.

      The table below sets forth the name of each Class III director nominated
by the board to serve as a director for a term ending in 2009. All of the
nominees are currently directors of the Company for terms expiring at the
meeting. Each nominee has consented to be named as a nominee and, to the present
knowledge of the Company, is willing to serve as a director, if elected. Should
any of the nominees not remain a nominee at the end of the meeting (a situation
which is not anticipated), solicited proxies will be voted in favor of those who
remain as nominees and may be voted for substitute nominees. Unless contrary
instructions are given on the proxy, the shares represented by a properly
executed proxy will be voted "FOR" the election of Michael J. McDevitt and
George Lavin Jr. Esq.

                      MEETINGS AND COMMITTEES OF THE BOARD

      For the fiscal year ended December 31, 2005 ("Fiscal 2005"), the Board of
Directors held four meetings, including those in which matters were adopted by
unanimous written consent. All Board members attended at least 75% of the Board
meetings. The Board has an Audit Committee, an Executive Committee, a Nomination
Committee and a Compensation Committee. The purpose and responsibilities for
each of these committees is outlined in committee charters adopted by the Board.
The Board may, from time to time, form a new committee or disband a current
committee depending on circumstances. In addition, the Board may determine to
form ad hoc committees from time to time, and determine the composition and
areas of competence of such committees.

      The Audit Committee of the Board of Directors consists of Mrs. Mary T.
Travis, Rev. Joseph Calderone, O.S.A. and Mr. George Lavin, Esq. The Audit
Committee is composed entirely of independent directors according to the
definition of "independence" set forth in the rules of the American Stock
Exchange. The Board of Directors has determined that Mrs. Mary Travis is an
Audit Committee financial expert "as defined under the rules of the Securities
and Exchange Commission". The duties and responsibilities of the Audit Committee
are described in the Company's Audit Committee Charter and include, among other
things, review of the Company's financial statements, review and ascertain
Company Compliance with all Sarbanes - Oxley regulations and requirements,
consideration of the nature and scope of the work to be performed by the
Company's independent auditors, discussion of the results of such work, the
receipt from such auditors of their letters to management which evaluate (as
part of their annual audit of the Company's financial statements) the internal
accounting control systems of the Company and meeting with representatives of
management to discuss particular areas of the Company's operations. The Audit
Committee held four meetings during 2005.

      Messrs. Michael C. MacDonald, Michael J. McDevitt, and Bradley T.
MacDonald are members of the Executive Committee. The Executive Committee has
all the authority of the Board of Directors, except with respect to certain
matters that by statute may not be delegated by the Board of Directors. The
Committee meets periodically during the year to develop and review strategic
operational and management policies for the Company. The Committee held three
(3) meetings during fiscal year 2005.


      The Compensation Committee of the Board of Directors held two (2) meetings
during fiscal year 2005. The members were Rev. Donald F. Reilly O.S.A, Mr.
George Lavin, Jr., Esq., and Mrs. Mary T. Travis. The primary purpose of the
Compensation Committee is to assist the Board in discharging its
responsibilities with respect to compensation of the Company's executive
officers and to produce an annual report for inclusion in the Company's proxy
statement on executive compensation. The compensation committee held three
meetings during 2005. The Committee approved a contract base salary for Mr.
MacDonald, the Chief Executive Officer of $225,000, which has remained the same
since 2003. In addition, the board made a $100,000 contribution to his Selective
Retirement Plan for his performance in 2005.

      The Chairman of each committee, in consultation with the committee
members, will determine the frequency and length of the committee meetings
consistent with any requirements set forth in the committee's charter. The
Chairman of each committee, in consultation with the appropriate members of the
committee and management, will develop the committee's agenda. The schedule for
each committee will be furnished to all directors.

                          REPORT OF THE AUDIT COMMITTEE

      The Audit Committee is composed of three directors who are independent, as
defined under the listing standards of The American Stock Exchange, and operates
under a written charter adopted by the Company's Board of Directors.

      The purpose of the Audit Committee is to assist the Board of Directors in
its general oversight of the Company. The primary responsibilities of the Audit
Committee are to review and evaluate the Company's audited financial statements
and to monitor and oversee the Company's internal control system, its accounting
and financial reporting process, its independent audit function and its
compliance with applicable laws and regulations. Management is responsible for
the preparation, presentation and integrity of the Company's financial
statements, accounting and financial reporting principles, internal controls and
procedures designed to assure compliance with accounting standards, applicable
laws and regulations. The Company's independent auditing firm is responsible for
performing an independent audit of the consolidated financial statements in
accordance with generally accepted auditing standards and in compliance with the
provisions of the Sarbanes-Oxley Act.

      The Audit Committee members are not professional accountants or auditors,
and are not responsible for conducting reviews of auditing or accounting
procedures, nor can the Audit Committee certify that the independent auditor is
"independent" under applicable rules. The Audit Committee serves a board-level
oversight role in which it provides advice, counsel and direction to management
and the auditors on the basis of the information it receives, discussions with
the auditors and the experience of the Audit Committee's members in business,
financial and accounting matters.

      Recent years have brought a wave of new legislation and regulations in the
area of corporate governance and financial reporting as the U.S. government took
unprecedented measures to set new standards for corporate behavior and to
restore investor confidence. The Company has a long history of corporate
responsibility and good citizenship, and has taken appropriate measures to
respond to the new standards. The Audit Committee took a lead role in overseeing
the efforts of the Company's Controller's Group, Internal Audit Department,
Legal Department, and independent accountants in ensuring the Company's
compliance with these reforms.

                                       AUDIT COMMITTEE


                                       Mary Travis

Company, L.L.C. has been the Company's independent accountants for the fiscal

Compensation of Directors

      The Company is authorized to pay a fee of $300 for each meeting attended
by its directors who are not executive officers. It reimburses those who are not
employees of the Company for their expenses incurred in attending meetings.
Independent Directors claimed $56,400 in Director's fees and/or expenses in
2005. See "Executive Compensation - Stock Options" for stock options granted
under the 1993 Plan to the Directors

         REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

      The Compensation and Stock Options Committee (the "Committee") is
authorized to review and make recommendations to the board as to the
compensation in cash or other forms for its executive officers, as described
below. The Committee currently has three members,


      COMPENSATION MIX

      The Company's executive compensation packages generally include three
components: base salary, a discretionary annual cash bonus, stock options and
grant of restricted common stock. The committee generally reviews, and makes any
changes to, the base salary and bonus of each executive officer as of the
beginning of each calendar year.

      Base Salary

      The Company's compensation policy is to provide for base salaries, which
are comparable to the compensation paid to executive officers of equivalent
competency and responsibilities by companies of comparable size and
capitalization both in and out of the cellular accessories industry.

      Discretionary Cash Bonus

      The Committee believes that discretionary cash bonuses are useful on a
case-by-case basis to motivate and reward executive officers. Bonuses for
executive officers are not guaranteed, but are awarded from time to time only in
the discretion of the Committee. Criteria for bonuses for executive officers
range from success in increasing revenues to attracting equity capital.

      Stock Options

      Grants of stock options under the 1993 Stock Option Plan are designed to
promote the identity of the long-term interests between the Company's executives
and its stockholders and to assist in the retention of executives. Since stock
options granted by the Company generally become exercisable over a multi-year
period, their ultimate value is dependent upon the long-term appreciation of the
Company's stock price and the executive's continued employment with the Company.
In addition, grants of stock options may result in an increase in executive
officers' equity interests in the Company, thereby providing such persons with
the opportunity to share in the future value they are responsible for creating.

                                       Mary T. Travis
                                       Rev. Donald F. Reilly, OSA
                                       Michael J. McDevitt

      This report of the Committee shall not be deemed incorporated by reference
by any general statement incorporating by reference this proxy statement into
any filing under the Securities Act or under the Exchange Act, except to the
extent that the Company specifically incorporates this information by reference,
and shall not otherwise be deemed filed under the Securities Act and the
Exchange Act and shall not be deemed soliciting material.

                       SELECTIVE EXECUTIVE RETIREMENT PLAN

      On May 23, 2003 the Board of Directors approved a Selective Executive
Retirement Compensation Plan funded by the form of deferred compensation. The
Deferred Compensation Plan was funded up to $350,000 by a dollar for dollar
match program, having Mr. MacDonald defer $175,000, followed by a Company match
of $175,000. In June 2004, the Board of Directors authorized an additional
$50,000 to be deferred by Mr. MacDonald followed by a Company match of $50,000.
In 2005, the Board of Directors approved the funding of $100,000 into Mr.
MacDonald's Selective Executive Retirement Compensation Plan. This brought the
Selective Executive Retirement Compensation Plan total funded value to $550,000.
Beginning January 1, 2006 the agreement was modified whereby the deferred
compensation will be earned over a 5-year vesting period due January 1, 2011.


                         LONG-TERM EMPLOYMENT CONTRACTS

      The Board of Directors of Medifast, Inc. is in the process of implementing
a management succession plan which will take place over the next 24 months. In
doing so, they have had 3 key executive officers sign 6-year employment
contracts to ensure that there will be minimal turnover in selected key
management positions. The Executives associated with this succession plan
include Michael S. McDevitt, President and Chief Financial Officer, Margaret
MacDonald, VP of Operations and Brendan Connors, CPA, VP of Finance. Bradley T.
MacDonald, the Executive Chairman of the Board of Directors and CEO has signed
and executed a new 5 year employment agreement as the Executive Chairman of the
Board of Directors and will provide on-going executive mentoring, financial and
M&A advice, and new business development for the Company.

      On February 8, 2006, the three executive officers of the company signed
6-year employment contracts. The officers received shares of common stock in
varying amounts totaling 380,000 shares at $6.25 per share that will be vested
over 6 years. In addition, Bradley T. MacDonald, Chairman and CEO signed a new
5-year employment agreement and was granted 100,000 stock options at $6.25 that
will vest over 5 years beginning on February 8, 2007.

Compensation Committee Interlocks and Insider Participation

      The Compensation Committee of the board is currently composed of Rev.
Donald F. Reilly, OSA, Mr. George Lavin, Jr., Esq. and Mrs. Mary Travis. None of
the members of the Compensation and Stock Option Committee were employees of the
Company during the year ended December 31, 2005.
