The timing of food intake plays a crucial role in obesity and weight loss treatment. In humans, breakfast skipping is causally linked to obesity and late lunch hinders weight loss. Late lunch has a deleterious effect on microbiota diversity and composition. Late dinner (within two hours before bedtime) decreases glucose tolerance specially in G carriers of the risk allele at MTNR1B. In addition, we have shown that individual chronotype is important in obesity. In evening chronotypes who eat at night (during the two hours before sleep) the probability of being obese increases five times, while in morning chronotypes with high caloric intake during morning hours (two hours after wake time) the probability of being obese decreases by 50%.
