                      NUTRITION MANAGEMENT SERVICES COMPANY
                           A PENNSYLVANIA CORPORATION
                  CERTIFICATION OF PRINCIPAL EXECUTIVE OFFICER
                            Section 302 Certification

I, Joseph Roberts, certify that:

      1.    I have  reviewed  this  quarterly  report on Form 10-Q of  Nutrition
            Management Services Company;

      2.    Based on my knowledge,  this  quarterly  report does not contain any
            untrue statement of a material fact or omit to state a material fact
            necessary to make the statements made, in light of the circumstances
            under which such  statements  were made, not misleading with respect
            to the period covered by this quarterly report;

      3.    Based on my knowledge, the financial statements, and other financial
            information included in this quarterly report, fairly present in all
            material respects the financial condition, results of operations and
            cash flows of the  registrant as of, and for, the periods  presented
            in this quarterly report;

      4.    The registrant's other certifying officers and I are responsible for
            establishing and maintaining  disclosure controls and procedures (as
            defined  in  Exchange  Act  Rules  13a-15e  and  15d-15(e))  for the
            registrant and have:

            a)    designed such disclosure  controls and  procedures,  or caused
                  such  disclosure  controls and procedures to be designed under
                  our supervision,  to ensure that material information relating
                  to the registrant, including its consolidated subsidiaries, is
                  made known to us by others within those entities, particularly
                  during  the  period in which  this  quarterly  report is being
                  prepared;

            b)    evaluated the  effectiveness  of the  registrant's  disclosure
                  controls  and  procedures  and  presented  in this  report our
                  conclusions about the effectiveness of the disclosure controls
                  and  procedures,  as of the end of the period  covered by this
                  report based on such evaluation; and

            c)    disclosed  in  this  report  any  change  in the  registrant's
                  internal control over financial reporting that occurred during
                  the   registrant's   most  recent  fiscal   quarter  that  has
                  materially  affected,  or is  reasonably  likely to materially
                  affect,  the  registrant's  internal  control  over  financial
                  reporting; and

      5.    The  registrant's  other  certifying  officers and I have disclosed,
            based  on our  most  recent  evaluation  of  internal  control  over
            financial  reporting,  to the  registrant's  auditors  and the audit
            committee of registrant's  board of directors (or persons performing
            the equivalent functions):

            a)    all significant  deficiencies  and material  weaknesses in the
                  design  or  operation  of  internal   control  over  financial
                  reporting which are reasonably  likely to adversely affect the
                  registrant's ability to record, process,  summarize and report
                  financial information; and

            b)    any fraud,  whether or not material,  that involves management
                  or  other  employees  who  have  a  significant  role  in  the
                  registrant's internal control over financial reporting.
