Official title
Comparison of Weight Loss Induced by Intermittent Fasting Versus Daily Caloric Restriction in Individuals With Obesity: A 1-Year Randomized Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary aim of this study is to is to determine if intermittent fasting (IMF) is an effective dietary strategy for treatment of obesity. A 1 year randomized trial will be used to compare weight loss generated by IMF versus Daily Caloric Restriction (DCR). The targeted weekly energy deficit is designed to be similar (\~30%) and a comprehensive behavioral support program will be provided to both groups. The primary outcome is weight change at the end of the 1 year intervention; follow up measures will also be obtained 6 months after completing the intervention. This study will provide robust data regarding weight loss effectiveness of IMF and will further our understanding of the impact of IMF on energy balance.
