And if you tell your kids, "No sugar, sugar makes you hyper," they're going to believe it.

Myth #5: Snacking at bedtime causes more weight gain than earlier in the day
Answer: FALSE
When it comes to managing weight, one simple rule trumps all others: If you take in more calories than you burn, you will gain weight. "It doesn't matter when calories are consumed," Vreeman says. One could eat all his or her daily calories before bedtime without putting on pounds?as long as the number of calories consumed does not exceed those burned.
Myth #4: Most of our body heat escapes through the tops of our heads
Answer: FALSE
How many times has your mom told you to wear a hat to keep heat from escaping your body on a cold, wintry day? Well, guess what? Some heat does escape through the head but certainly not the bulk of it, according to the researchers. "Heat loss is proportional to the body's surface area that is exposed. Your head has a decent amount of surface area," she says, but notes that the arms, legs and torso do, too. "By all means wear a hat, but there is nothing special about the head."
*whoooosh* The researchers completely missed the point of the "myth". The fact that the US Army Field manual doesn't recommend wearing a jacket is because, well, they expect some common sense. Does anyone think the US Army Field manual implies that if you run around naked outside, wearing only a hat, that you'll barely lose more body heat than if you wore a down jacket and no hat? Of course not. No one is that stupid (hopefully), but these mythbusters seem to think that it's what the myth implies.We've all been told to put a hat on in winter because most heat is lost through the head.
The researchers even found that the US Army Field manual for survival recommends covering your head in cold weather because around 40-45% of body heat is lost through the head.
A recent study, however, showed there is nothing special about heat loss from the head - any uncovered part of the body would lose heat.

It's pretty simple to show where heat is lost the fastest in a body.
exhibit 1
exhibit 2
Simple IR imaging shows where most of the heat is lost. The whiter the area, the more heat that's lost. (IR cameras "see" IR, which means IR energy is radiated away)
So, tell me, where is most of the heat being lost by those guys just wearing ordinary shirts? Now, how big of a difference do you think it's going to be if they're outdoors in freezing temperatures? These modern mythbusters: idiots.

DHOOO!!!!!
Post IR pictures of naked people and we will see what part loses heat more rapidly.

Yep. Here, let me try for one sentence:
If you don't wear a hat, the majority of the heat that your body loses is going to be from your head.
The researchers trying to "bust this myth" interpreted that as running around outside naked. It's assumed by anyone with common sense that if it's really cold outside, cold enough that you might start thinking about wearing a hat, you're probably going to be wearing other clothes, including a jacket.
