Comparison Between Regular Exercise and Calorie Deficit in Achieving Sustainable Weight Loss: An Article Review

Abstract

This review examines the comparative effectiveness of regular exercise and calorie deficit strategies in achieving sustainable weight loss among overweight/obese individuals. A literature search was conducted using ScienceDirect, PubMed and Google Scholar for relevant studies published between 2014 and 2024. Of the 14 articles initially identified, 11 met the inclusion criteria for this analysis. The reviewed interventions included various forms of regular exercise such as aerobic, resistance and low-intensity activities as well as calorie deficit approaches, including continuous calorie restriction, intermittent calorie restriction, time-restricted eating and very low-calorie diets. Overall, both strategies demonstrated consistent positive effects on weight reduction. While each method showed distinct benefits, modest evidence suggests that combining regular exercise with calorie restriction may yield greater improvements in body weight and waist circumference. These findings highlight the potential of integrated approaches tailored to individual needs in supporting long-term weight management.
