Outcome Measures

Primary Outcomes (2)

  • Change in BMI

    Unit of measure: BMI in kg/m\^2 (weight in kilograms, height in meters)

    Change in BMI between baseline and the end of the treatment (day 15) and follow-up (a month after day 15)

  • Change in BMI

    Unit of measure: BMI in kg/m\^2 (weight in kilograms, height in meters)

    Change in BMI between baseline and follow-up (a month after day 15)

Secondary Outcomes (16)

  • Change in food addiction symptoms on the Yale Food Addiction Scale (YFAS)

    The change in the number of symptoms on day 15 compared to baseline will be assessed.

  • Change in food addiction symptoms on the Yale Food Addiction Scale (YFAS)

    The change in the number of symptoms on day 16 (a month after day 15) compared to baseline will be assessed.

  • Cognitive regulation of eating

    The change in reaction time on the Food Stroop task between day 15 and baseline.

  • Cognitive regulation of eating

    The change in reaction time on the Food Stroop task between day 16 (a month after day 15) and baseline.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Having satisfied a safety screening questionnaire for TMS (Keel, 2001)
  • Omnivorous
  • Have not had experience with TMS of any kind

You may not qualify if:

  • They experience tremor in any limb.
  • They experience seizures.
  • They have a history of epilepsy or seizure (EXCEPT those therapeutically induced by ECT, or febrile childhood seizures).
  • They are at increased risk for seizures for any reason, including prior diagnosis of increased intracranial pressure (such as after large infarctions or trauma), or a history of significant head trauma with loss of consciousness for \> 5 minutes.
  • A history of clinically significant neurological disorders, including organic brain disease, epilepsy, stroke, brain lesions, multiple sclerosis, previous neurosurgery or personal history of head trauma that resulted in loss of consciousness for \> 5 minutes and retrograde amnesia for \> 30 minutes (self-reported history).
  • They have a clinically significant hearing impairment, unless a medical letter is provided permitting the participant to receive a dTMS treatment.
  • The participant has an unstable physical disease, such as acute unstable cardiac disease, or high blood pressure (\>150 mmHg, systolic/\> 110 mmHg diastolic, unless a medical letter is provided permitting the participant to receive a dTMS treatment.
  • They experience tremor in any limb.
  • They experience seizures.
  • They have a history of epilepsy or seizure (EXCEPT those therapeutically induced by ECT, or febrile childhood seizures).
  • They are at increased risk for seizures for any reason, including prior diagnosis of increased intracranial pressure (such as after large infarctions or trauma), or a history of significant head trauma with loss of consciousness for \> 5 minutes.

  • They have a clinically significant hearing impairment, unless a medical letter is provided permitting the participant to receive a dTMS treatment.
  • The participant has an unstable physical disease, such as acute unstable cardiac disease, or high blood pressure (\>150 mmHg, systolic/\> 110 mmHg diastolic, unless a medical letter is provided permitting the participant to receive a dTMS treatment.
  • The participant is at a high risk for severe violence or suicidal tendencies, has current DSM5 diagnosis of schizophrenia, bipolar disorder, or other psychotic disorder, as reported during the screening interview (see appendix 3).
