Please Explain: Calories

Friday, September 20, 2013

Food is measured in calories. People sometimes count calories and cut calories, and this week’s Please Explain is all about what calories are, how they’re measured, how we burn them, and if they differ from food to food. Joining us are: Dr. Kelly D. Brownell, Dean of the Sanford School of Public Policy and Professor of Public Policy at Duke University. And Russell Rising, Research Associate in the Metabolic Laboratory at the Obesity Research Center at St. Luke's-Roosevelt Hospital.

I note for the commentboard that I will feel warm and require less food and heating for up to 2 hours after a brisk 30 minute walk. The beneficial effect lasts past the end of the exercise.

Could the guests comment on the difference btwn. simple & complex carbs?

And for the caller trying to gain weight, what about dried foods? Aren't they more calorie-dense?

I really wish the guests would talk about the difference in SATIETY between fat calories and carbohydrate calories. If someone eats a small amount of fat vs. a large amount of carbs, the calories may be the same but the person is less likely to overeat after the fat intake.

Also, I'd like them to talk about impaired metabolic process that has nothing to do with calories. It's not always a matter of calories in-calories out.

If calorie count is off, then it's probably true that quantities of sodium, cholesterol, saturated fats, etc. is also inaccurate?

I tend to eat and cook "whole foods" e.g., just chicken breast, olive oil, lettuce, potatoes, apples, etc., and measure my calories that way (I often weigh it too). I assume, perhaps incorrectly?, that when I measure calories via USDA Food database are close to correct, at least more so than processed food. Is that a sound assumption?

interesting topic but Russell's enunciation makes him difficult to understand

Now that NY restaurants list calories on menus (which I think is helpful), how do they figure all of those calorie counts for those dishes? Is it reasonable to believe they are accurate?
