Eating More Carbohydrates at Night May Leave You Feeling Fuller
According to a recent study, eating carbohydrates at dinner time may change the way your body secretes the hormones that let you know if you're hungry or full.
The study included 78 participants with a BMI of 30 or greater. They ate either a low-calorie carbohydrate-rich dinner or a control weight loss diet that provided carbohydrates throughout the day for six months.
The researchers looked at the levels of three different hormones that play a role in hunger.
1. Leptin, the hormone responsible for feelings of satiety. Levels usually peak at night.
2. Ghrelin, the hormone that makes you feel hungry. Levels are usually high all day and low at night.
3. Adiponectin, the hormone that modulates glucose regulation. Levels are usually low in overweight people.
At the conclusion of the half year trial period, the researchers found that the daylight hormonal profiles of the participants that ate the low-calorie carbohydrate-rich diet had changed. Leptin levels were high during the day and lowest during the evening. Ghrelin levels were low during the day and highest in the evening. Apdiponectin levels were higher at the end of the study.
The researchers concluded that a diet with high carbohydrate consumption in the evening may help obese people avoid mid-day hunger, lose more weight and improve metabolic parameters.
The study was conducted at the Institute of Biochemistry, Food Science and Nutrition at Hebrew University's Robert H. Smith Faculty of Agriculture, Food and Environment. The results were published in two studies: one in the October 2011 issue of Obesity and one in the journal Nutrition, Metabolism & Cardiovascular Disease online ahead of print on August 14, 2012.
