(n = 403) reported in a cross-sectional study that for carriers of Circadian Locomotor Output Cycles Kaput (CLOCK) gene polymorphisms, delayed eating times for breakfast and lunch increased the odds of obesity by 2.95 (95% CI = 1.77, 4.90) and 1.53 (95% CI = 1.32, 1.89) respectively after adjustment for age, sex and 6 other confounders (36). Here, CLOCK is linked to obesity due to melanocortin 4 receptor deficiency.
