Participant milestones
| Measure |
Arm 1: LSMT 12
Participants in this arm will start LSMT at baseline and have a weight loss response assessment at 12 weeks: if body mass index (BMI) is down 5% at 12 weeks, the participant will continue with LSMT for the remainder of the study.
|
Arm 1: LSMT 12 + Phentermine
Participants in this arm will start LSMT at baseline and have a weight loss response assessment at 12 weeks: if BMI is not down 5% at 12 weeks, the participant will add phentermine to LSMT (phentermine+LSMT) and undergo a second weight loss response assessment after 12 weeks of phentermine+LSMT; i.e. at 24 weeks.
|
Arm 1: LSMT 12+Phentermine+Topiramate
Participants in this arm will start LSMT at baseline and have a weight loss response assessment at 12 weeks: if body mass index (BMI) is down 5% at 12 weeks, the participant will continue with LSMT for the remainder of the study; if BMI is not down 5% at 12 weeks, the participant will add phentermine to LSMT (phentermine+LSMT) and undergo a second weight loss response assessment after 12 weeks of phentermine+LSMT; i.e. at 24 weeks.

|
Arm 2: LSMT+Topiramate+Placebo
Participants in this arm will start LSMT at baseline and have a weight loss response assessment at 24 weeks: if BMI is not down 5% at 24 weeks, the participant will add phentermine to LSMT (phentermine+LSMT) and undergo a second weight loss response assessment after 12 weeks of phentermine+LSMT.

LSMT 12
n=11 Participants
Participants in this arm will start LSMT at baseline and have a weight loss response assessment at 12 weeks. If body mass index (BMI) is down 5% at 12 weeks, the participant will continue with LSMT for the remainder of the study; if BMI is not down 5% at 12 weeks, the participant will add phentermine to LSMT (phentermine+LSMT) and undergo a second weight loss response assessment at week 24.
|
LSMT 12+Phentermine
n=24 Participants
At 24 weeks, if BMI is down 5% with phentermine+LSMT, the participant will continue with phentermine+LSMT for the the remainder of study; if BMI is not down by 5% at 24 weeks, the participant will be randomized to topiramate+phentermine+LSMT or topiramate+placebo+LSMT for the remainder of the study.
Subjects will take 15 mg of phentermine every morning.
|
LSMT 12+Phentermine+Topiramate
n=19 Participants
At 24 weeks if BMI is not down by 5% the participant will be randomized to topiramate+phentermine+LSMT or topiramate+placebo+LSMT for the remainder of the study.
Phentermine Pill: Subjects will take 15 mg of phentermine every morning.
Topiramate Pill: Topiramate will begin at 50 mg every morning for 7 days, then increase to 100 mg every morning. At the end of week 48 the taper off will be 50 mg every morning for 7 days and then discontinue.

LSMT 12+Topiramate+Placebo
n=20 Participants
At 24 weeks, if BMI is down 5% with phentermine+LSMT, the participant will continue with phentermine+LSMT for the the remainder of study; if BMI is not down by 5% at 24 weeks, the participant will be randomized to topiramate+phentermine+LSMT or topiramate+placebo+LSMT for the remainder of the study.
Topiramate Pill: Topiramate will begin at 50 mg every morning for 7 days, then increase to 100 mg every morning. At the end of week 48 the taper off will be 50 mg every morning for 7 days and then discontinue.
Placebo Pill: Participant will take one placebo pill each morning.
