This is a multicenter, randomized, evaluator and subject blinded, parallel-group, controlled study intended to evaluate the safety and efficacy of treating obese patients with the placement of g-Cath EZ suture anchors followed by a structured diet and exercise plan as compared to a sham procedure followed by the same diet and exercise plan. Subjects will be randomly assigned in a 2:1 ratio to the treatment procedure followed by diet and exercise or the sham procedure followed by diet and exercise. After un-blinding at 12 months post-treatment, sham patients can choose to have the treatment procedure as well.

Primary Outcome Measures:
  • Total Body Weight Loss [ Time Frame: Enrollment to 12 months ]
    Evaluate the effectiveness of the g-Cath EZ™ Suture Anchor Delivery Catheter (USGI Medical, San Clemente, CA, USA) with diet and exercise as an early weight loss intervention for Class I obesity subjects with at least one non-severe obesity related co-morbid condition or Class II obesity subjects with or without a non-severe obesity related co-morbid condition compared to a sham procedure, diet and exercise group.

Secondary Outcome Measures:
  • Quality of Life scores (IWQOL) [ Time Frame: enrollment to 12 months ]
    Assessment of changes

  • Comorbid status [ Time Frame: Enrollment to 12 months ]
    Assessment of changes from baseline at 12 months in hypertension, diabetes, and hyperlipidemia

  • Eating Behavior changes [ Time Frame: Enrollment to 12 months ]
    assessment of changes from baseline at 12 months in eating behavior scores (TFEQ) and subjective changes in food capacity, hunger, and satiety in both study groups
