Calories

Losing weight is easy, absent some real medical problem. Ready? Here we go:

If you eat more calories than you burn, you will gain weight.

If you burn more calories than you eat, you will lose weight.

The more of a difference between burning and eating, the faster you will gain or lose weight.

Now, burning calories doesn’t just mean exercise, although that’s an important part of it. It’s also what you burn just walking around during the day. Or sitting in front of the computer. Or sleeping. What this means is if you take in 2000 calories in a day, you don’t have to burn 2000 calories doing exercise….

“Knowing your Daily Calorie Needs is more than knowing how many calories your body needs for its basic physiologic functions (known as your Resting Metabolic Rate or BMR). It’s also important to know how many calories your body needs to maintain certain daily activities. By combining your resting metabolic rate and your daily activity level, you will get the total number of calories your body needs during the day.”

A tip: if you’re not sure what activity level you should use, calculate each in turn and make a separate note of them, so you can get a sense of both the range you should be in on a given day, but also giving you some flexibility — if I want to eat that stuff I should incorporate some exercise.

Beyond Tang: Food in Space

Earlier this year, NPR’s Morning Edition had a story with a behind-the-scenes look at NASA’s space food lab, where scientists fashion non-goo meals for astronauts:

“Beyond Tang: Food in Space” — NASA’s Johnson Space Center invited The Kitchen Sisters to visit its “hidden kitchen.” On the eve of NASA’s scheduled launch of space shuttle Atlantis, The Kitchen Sisters present a brief history of space food.

I came across this story thanks to checking out the NPR Hidden Kitchens podcast, unfortunately not updated since June. Hopefully they’ll have more installments to come in the near future, since I love the idea:

An ongoing series exploring the world of hidden kitchens: street-corner cooking, legendary meals and eating traditions…how communities come together through food.

Compare with the verboten foods of the Paleolithic Diet — no grains, no beans, no dairy, etc. — as well as the items all three of these have in common. Somewhere in the middle, the truth lies.

Guinness good for you. And the Pope is Catholic.

Guinness is good for you

Drink a Guinness for your health! The BBC is reporting on a study that shows a Guinness a day keeps the heart doctor away.

A pint of the black stuff a day may work as well as an aspirin to prevent heart clots that raise the risk of heart attacks.

Since I always feel better after having a pint of Guinness, this seems to confirm my findings. ;)

Tea healthier than water?

So asking the replicator for “Tea, Earl Grey, Hot” does a body better than “Water, Bottled, Cold”? This according to a story on the BBC News website: “Tea ‘healthier’ drink than water”:

Drinking three or more cups of tea a day is as good for you as drinking plenty of water and may even have extra health benefits, say researchers.

The work in the European Journal of Clinical Nutrition dispels the common belief that tea dehydrates.

Tea not only rehydrates as well as water does, but it can also protect against heart disease and some cancers, UK nutritionists found.

Experts believe flavonoids are the key ingredient in tea that promote health.

Some very interesting tidbits in there, though the fact that the research was funded by the Tea Council casts a bit of doubt on the whole thing. Still, better than a six pack of soda every day.
