                      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,  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  in  the  design  or  operation  of
              internal  controls 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.
