Recent months have shown an uptick in notable articles that discuss the timing of meals, rather than the macronutrient or calorie content. This review published today in The Journal of Physiology focuses on time-restricted feeding (TRF), an approach that limits food intake to a period of less than 12 hours. Our circadian clock is controlled partly by exposure to light, but the timing of our exposure to food is another important factor. For example, people with diabetes who awake later in the day and who eat more in the evening are more likely to be obese and have higher A1Cs. Misalignment of sleep patterns for just three days in a lab increases glucose through effects on both beta cell function and insulin sensitivity. The clinical suggestions from this review would be to decrease late evening eating and to shift food intake to earlier in the day. This fits in very well with the recent Scientific Statement by the American Heart Association.
