Color me surprised to find out that eating a daily amount of yogurt helps reduce belly fat... The article I read states:
Yogurt, Specifically, Significantly Increases Fat Loss
In just 3 months, 16 obese men and women on a reduced calorie diet that included three daily portions of yogurt lost 61% more fat and 81% more abdominal fat than 18 obese subjects assigned to a diet with the same number of calories but little or no dairy products and low amounts of calcium.
Not only did those in the yogurt group lose more fat, especially around their waistlines, but they also retained more lean, muscle tissue than subjects on the yoghurt-free diet.
How yogurt promotes fat loss while preserving muscle is still a matter of debate. It may be due to the fact that calcium reduces fat cells' ability to store fat, so cells burn more, and less is produced in the liver. Or, it may be due to the branched chain amino acids present in dairy products. Regardless, this study, published in the International Journal of Obesity, indicates that adding one or two servings of yogurt to your daily diet can help you maximize loss of fat and minimize loss of muscle-the optimal outcome for any diet.
Calcium-rich Dairy Foods Boost the Body's Fat Burning After a Meal
Yet another study suggests those ads linking a daily cup of yogurt to a slimmer silhouette have a real basis in scientific fact. Research published in the American Journal of Clinical Nutrition not only confirms earlier studies showing a calcium-rich diet is associated with fat loss, but may help explain why.
Normal-weight women ranging in age from 18-30 years were randomly assigned to a low (less than 800 mg per day) or high (1000-1400 mg per day) calcium diet for 1 year, and the rate at which their bodies burned fat after a meal was assessed at the beginning and end of the study.
After 1 year, fat oxidation (burning) was 20 times higher in women eating the high calcium diet compared to those in the low-calcium control group (0.10 vs. 0.06 gram per minute).
The women's blood levels of parathyroid hormone were also checked and were found to correlate with their rate of fat oxidation. (The primary function of parathyroid hormone is to maintain normal levels of calcium in the body. When calcium levels drop too low, parathyroid hormone is secreted to instruct bone cells to release calcium into the bloodstream.)
Higher blood levels of parathyroid hormone were associated with a lower rate of fat oxidation and lower dietary calcium intake, while lower blood levels of parathyroid hormone levels were seen in the women consuming a diet high in calcium, who were burning fat more rapidly after a meal. So, it appears that a high-calcium diet increases fat oxidation, at least in part, by lessening the need for parathyroid hormone secretion, thus keeping blood levels of the hormone low.
Interesting. Gonna make sure I have at least 6-12 ounces of fat-free yogurt daily! Let's see if it'll help me shed the gut!
