A multicenter, prospective, single-arm, open-label, controlled clinical trial aimed to evaluate the safety and effectiveness of the EndoZip system procedure, coupled with lifestyle modifications, for weight reduction in obese patients with BMI of 30-40 kg/m2.

study will include up to 45 (10-20 patients per site), ages of 21 -70 of obese patients who failed to reduce weight with non-surgical weight-loss methods.

The duration for each participant will be 12 months and will include the following follow up visits and procedures:

• Office visits: screening, 1 week, and 1, 2, 4, 6, 8, 10, and 12 month(s)
• Remote follow up (by Phone): 3, 5, 7, 9, and 11 month(s)
• Endoscopy procedure: baseline, 2 and 6 months post EndoZip procedure
• Motility evaluation by Gastric Emptying Breath Test (GEBT): baseline, 6 months
• Physical examination, vital signs, waist circumference and BMI: baseline, 1 week, 1, 2, 4, 6, 8, 10 and 12 months
• Blood tests: baseline,2, 6 and 12 months
• IWQOL-Lite: baseline, 2, 6 and 12 months
• Psychological health questionnaire-9 (PHQ-9) :baseline
• Sleep Apnea (only for the relevant population): baseline 2, 6 and 12 months

The patient will required to follow a specific diet and to have a physical activity during the study period ( 12 month).
