The Obesity Society’s Annual Scientific Meeting has grown to be one of the world’s largest gatherings of obesity professionals at all stages of their careers, including leading obesity scientists presenting cutting-edge research. The meeting brings together the leading players in the field of obesity from world-renowned speakers, researchers and clinicians to educators, advocates, policymakers and practitioners. And, it provides essential educational and networking opportunities and is a forum for increasing knowledge, stimulating research, and promoting better treatment for those affected by this disease.

ObesityWeek 2017

Save the Date! In 2017, TOS and ASMBS are taking our annual conference to the nation's capital!

Gaylord National Resort & Convention Center, 201 Waterfront St, Oxon Hill, MD 20745 (Washington, DC metro area)
Pre-conference events: Monday, Oct. 30 – Tuesday, Oct. 31, 2017
Scientific Sessions: Wednesday, Nov. 1 – Friday, Nov. 3, 2017

TOS call for Symposium Submissions is open from Nov. 18 - Dec. 23, 2016.

The Program Committee hopes to accept many symposia with no or only minor modifications. These TOS member-submitted symposia will be highlighted in the 2016 program. Unlike previous years, the Program Committee hopes to minimize changes to member-suggested symposia, although some changes may be necessary to ensure the best possible overall program. Please submit your ideas now as TOS relies heavily on suggestions from our membership and partners to develop our outstanding sessions.

What you need to know to submit your symposia idea:

  • The deadline for submission is December 23, 2016 at 11:59 pm EST.
  • Please identify a track or tracks that are appropriate for the symposium suggestion. Joint/cross-track symposium are desirable. There will not be a category for Not Applicable or Other.
  • Symposium submissions should NOT duplicate topics covered in the last TOS meeting or suggestions from other conferences you've attended; TOS wants its program to be filled with fresh, new ideas.
  • Suggested speakers (2-4) may include a mix of TOS member and non-member speakers, though TOS members are preferred. Slots for international speakers are limited. Please be prepared to include credentials, place of business and e-mail addresses for all suggested speakers.
  • DO NOT contact suggested speakers in advance, as we cannot guarantee their inclusion in the program. Invitations will ONLY be made by members of the Program Committee and TOS staff.
  • TOS Sections are encouraged to submit symposium suggestions on behalf of their members. Such submissions will be given special consideration by the Program Committee for inclusion in the program, however this does not mean they will be accepted in their entirety. We encourage you to work with your Section members to help us design the best program.

Thank you for being our planning partner for our Annual Meeting at ObesityWeek 2017.
