Disturbance in Chrononutrition and Its Influence on Body Weight and Academic Performance: A Review

This study is a review of articles from 1999 to 2023 that present how circadian rhythm and factors have created an impact on individuals. Chrononutrition is the latest concept of sleeping patterns and eating behaviors along with it. It includes meal frequency, regularity, and timing. Alteration in these can be a reason for healthy eating or risk of diseases. The pros and cons of chronotypes (morning and evening) and their relation with modernization are being studied. Meal skipping and its influence on body weight are deleterious for health and breakfast skipping and late dinners have a higher association with weight gain. Disruption in sleep and high-calorie consumption before bedtime causes disturbed and insufficient sleep. Nutrient intake is low in individuals who have poor sleep-wake cycles. Also, irregularity in the sleep-wake cycles and meal timings have an association with poor academic performance of students of school, college, and university levels. In conclusion, eating with a biological clock can help individuals reverse or recover from a disease and create a positive impact on academic performance.
