For years we have been taught the calorie myth - a calorie is a calorie no matter where it comes from. While in terms of energy a calorie is a calorie, the type of food the calories come from can make a huge difference on physiological impact.  Thus the concept of the calorie myth: a calorie may not be a calorie nutritionally. In a recent JAMA commentary, Dr. David Ludwig, head of the Obesity Prevention Center at Boston Children’s Hospital, compares the impact of two very different foods: 

The longstanding low-fat diet dogma and the concomitant calorie myth has caused many frustrated people to blame overeating and sloth for their inability to lose weight, and this is wrong, said Ludwig.

Eating refined carbs, such as a 100-calorie pack of Oreos, produces a huge surge of insulin that signals your fat cells to store calories. In contrast, eating 100 calories of avocado won’t produce the same insulin charge. You’ll also feel fuller, longer, after eating the avocado, while the Oreos will make your blood sugar spike and rapidly crash, causing you to feel ravenous in short order.

According to Dr. Bill Lagakos, author of The poor, misunderstood calorie:

The calories in food are not the same as those expended by the body. Carb-rich foods are easily over-eaten, producing a positive energy balance. The accompanying elevations in insulin cause net fat storage. Maybe all calories are calories, but not all calories are equally obesogenic.

Seahawks vs. Broncos: Paleo vs. Standard Diet?

After watching the Seattle Seahawks painfully dominate the Denver Broncos in Super Bowl XLVIII, I was struck by the explosive nature of the Seahawks. They applied constant pressure on Manning and seemed to burst out of nowhere to quickly surround nearly every Bronco that ran or caught the ball. Puzzled, I wondered about each team’s diet. A quick, non-scientific search led to the following (emphasis added):

Seattle Seahawks

In an article published in the Seattle Times on January 8, Tan Vinh discusses the Seattle Seahawks’ diet with team chef Mac McNabb. The diet appears to be mostly Paleo:

eggs, … 60 dozen a week … whipped eggs for omelets

burrito …” “Gourmet, luxurious stuff”

tortilla stuffed with organic veggies, organic sausage and free-range eggs

egg-white omelet, this time with chicken sausage, mushroom, onion and cheddar, topped with a dollop of salsa

“smoked a 24-pound turkey, made gallons of smoothies, baked organic blueberry scones and endless trays of bacon and organic chorizo

“team goes through 50 pounds of fish and 60 pounds of beef every week”

fresh-fruit buffet

salmon entrée

“all organic and premium meat — grass-fed beef, free-range chicken — and few if any genetically modified foods”

salmon teriyaki, smoked briskets and what may be the most decadent gumbo in the city, brimming with medallion-size scallops, cod, salmon, mussels, clams all fresh or wild caught — along with andouille sausage

turkey burgers

pistachio-crusted Ono fish

Hawaiian BBQ

“chicken from Popeyes, which the team gets on Friday when lunch is catered”

“beverage aisle of a convenience store with rows of water, V-8 juices and yogurts

“Snacks are jerkys and granola bars stacked in plastic bins labeled “buffalo,” “turkey” and “honey sunflower seeds.”

“No sodas or junk food, but there are fresh-baked cookies on Thursdays.”

“No deep-fried food made in the kitchen. Even French fries are baked.”

“For post-practice, when McNabb puts out a pasta station, many players will shun a carb-loaded meal for something lighter.”

Vinh concludes:

“The days of seeing players like former defensive tackle Chad Eaton eat three, 22-ounce porterhouse steaks in one sitting are few and far between.”

“Take safety Kam Chancellor. At a recent breakfast, sporting a red Air Jordan hoodie and headphones, the 6-foot-3, 230-pound defender strolled in at 7:30, skipping the eggs and bacon for a bowl of oatmeal with brown sugar.”

“And quarterback Wilson had the most sensible (though maybe not the most appetizing) breakfast of the bunch. He grabbed a modest bowl of steel-cut oats, the portion size more fitting for a runway model. He then took a bowl of grapes and headed to the film room instead of mingling with teammates. He circled back later to request one fried duck egg.”

Denver Broncos

On the DenverBroncos.com site Stuart Zaas talks with linebacker Von Miller “about the importance of nutrition.” In the article team Nutritionist Brian Snyder provides an overview of the Broncos diet. With its carbohydrate focus, it is more representative of the standard modern diet:

“Typically, at the hotel I usually don’t vary the menu up too much because guys like consistency. We usually have a pretty good variety of pastas, proteins, cornbread, starches – it’s very carbohydrate focused with lean sources of protein and then at the stadium I have my normal snack table full of Gatorade bars. Guys like their routine. During the week I’ll change up the menu quite a bit but pregame I try to keep it consistent.”
