Is Fasting Superior to Continuous Caloric Restriction for Weight Loss and Metabolic Outcomes in Obese Adults? A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

ABSTRACT:

Background

fasting-based strategies (FBS) and continuous caloric restriction (CCR) are popular methods for weight loss and improving metabolic health. FBS alternates between eating and fasting periods, while CCR reduces daily calorie intake consistently. Both aim to create a calorie deficit, but it is still uncertain as to which is more effective for short- and long-term weight and metabolic outcomes.

Objectives

this systematic review and meta-analysis aimed to compare the effectiveness of FBS and CCR on these parameters in obese adults.

Methods

after screening 342 articles, 10 randomized controlled trials (RCTs) with 623 participants were included.

Results

both interventions led to weight loss, with a reduction of 5.5 to 6.5 kg observed at the six-month mark.
