Ability and willingness to complete all study visits and procedures; in particular an agreement to engage with: trying to use the device on a daily basis; the hypocaloric diet weight loss program; and this provided weight loss support and mentoring.
- 5\. Agreement not to use of prescription, or over-the-counter, weight loss preparations for the duration of the trial.
- 6\. Agreement not to start smoking tobacco or marijuana for the duration of the study.

Hypothyroidism requiring current treatment with levothyroxine (e.g. Levo-T, Synthroid, Thyroxine) (Other thyroid disorder patients on stable treatment for at least 3 months are acceptable).
- 7\. Other endocrinological causes of weight gain (e.g. Cushing's disease, Cushing's syndrome or acromegaly) 8. Previous diagnosis of HIV infection or AIDS (HIV is known to cause a vestibular neuropathy which would prevent VeNS from working).
