Purpose: The purpose of this article is to review the effectiveness of Intermittent Fasting, specifically, daily, time-restricted eating for the treatment of weight loss and improved health outcomes.

Method: Databases searched included PubMed and Google Scholar. Interlibrary loan requests were utilized to access full-text articles. Search filters used included: time-restricted feeding, time-restricted eating, intermittent fasting, obesity, caloric restriction.

Results: Time-restricted eating showed weight loss, a decrease in body fat, and an increase in lean body mass along with other non-weight related health outcomes.

Conclusion: Time-restricted eating patterns have shown positive results in weight loss, body fat, and appetite. Most studies indicate similar weight loss results compared to caloric-restricted diets concluding that time-restricted diets are a good alternative to caloric-restrictive diets. Future research focusing on the combination of both caloric-restrictive eating with a time-restricted eating pattern is needed to determine if the combination of modalities may be superior to caloric-restrictive diets alone. Further research should also focus on the longevity of time-restricted eating patterns and sustainability.
