Review on negative calorie foods & bread and oil appetite suppresser

My post earlier this month on negative calorie foods created a mini buzz about the truth in negative calorie fruits, which are known to be higher in sugar.

Claudia Meydrech, a certified nutritionist and blogger kindly answered this one for me and I wanted to pass it along with my readers:

“It's not so much the amount of sugar that is in the fruit, it is what it does once it is in the body. Though I have not seen any studies cited, and am not certain many have been done, I know that those who encourage negative calorie dieting state that these fruits and vegetables stimulate the body to produce certain digestive enzymes. This increases metabolism, and increased metabolism burns calories. In the case of negative calorie fruits and vegetables, more calories than the fruit/vegetable itself contains, even those that contain sugars.

Another thing to know about fruit-based sugars that is not related to the topic, they are not used in the body as quickly as refined sugars, causing the sugar highs and lows that are so hard on the pancreas.”

Another post from early April looked at the possible appetite suppression from a tablespoon of oil and a slice of whole wheat, whole grained bread.

Gay Riley, a certified clinical nutritionist and writer gave me some feedback on this one as well:

“Fat satiates and stays in the stomach longer, and the bread fills you up. I believe the protocol was 2 tsp olive oil (90 calories) plus a piece of wheat bread 110-180 calories. A good snack but high calorie for most. I will go for the theory that you will eat less dinner 20 minutes later if it is controlled portions. Basically it takes 20 minutes to get the CCK signal to the brain from the stomach via the vagus nerve that it is full or satisfied. Put simply. So if the theory is fullness and fat, then a salad with olive oil might do it as well. Just wait 20 minutes before you eat your meal. Olive oil is definitely a good thing all around but calorically it needs to be controlled for the benefits rather than the repercussions.”
