Humans aren’tmeant to graze

Your AnyBODY column “Skip a meal to lose weight? Not so fast, some experts say” [Aug. 27] cites research suggesting that nibbling throughout the day is beneficial because it raises the metabolic heart rate. The downfall of this eating pattern, the research suggests, is that “eating more frequently leads people to consume more calories.”

That is not the only downfall. Although your metabolic rate does indeed rise, which increases the calories burned while at rest, you are paradoxically consuming calories in order to burn calories. Thus, the idea that a person should eat a 100-calorie “snack” in order to raise their metabolic rate is folly, as the increased metabolic rate will only burn a portion of those calories.

We should forever dispose of the misguided notion that humans were meant to graze. I am committed to intermittent fasting — drastically restricting calories on one or two days per week and then eating normally on others. I have found it to be the most effective way to lose weight and keep it off.

More prenatal tests

New prenatal tests reveal far more about fetuses” [Aug. 27] accurately captures the surge of interest in prenatal tests and the development of new, less invasive procedures. But the story did not mention that among these new tests is Panorama, which looks for certain chromosome conditions in the baby, including additional sex chromosome abnormalities and triploidy, a disorder carrying health implications for the mother that cannot be detected by other technologies.
