One way I make it through my work out when I’mhuffing and puffing on the treadmill is to tell myself that after it’s all over, I can reward myself with a little extra food. That’s because exercise revs up metabolism, right? Wrong. For years the common refrain from fitness gurus and diet books has been that if you exercise regularly you’ll keep torching those Big Macs all day long–and even at night (“It’s a miracle! Lose weight while you sleep!”).
The “boost your metabolism” chorus makes many people scratch their heads when they start an exercise program and step on the scale a few weeks later to discover their weight hasn’t budged, or maybe they have even gained a pound or two. To help understand the relationship between activity and weight loss, a team of researchers studied the Hazda, a hunter-gatherer tribe in Tanzania, and published the results in an article in the most recent volume of the journal PLoS One.
Walking miles a day to find food, the Hazda’s lifestyle is far more active than the average American couch potato’s. The researchers outfitted the tribespeople with GPS devices and meticulously measured their energy output and metabolic rate. Surprisingly, what they found was that the Hazda burned only about as many calories a day as a typical Westerner. The team concluded that the primary cause of the obesity epidemic that is plaguing countries like the United States is not our sedentary lifestyles. They also point out that more exercise without a major diet overhaul will not solve the problem.
A second study, also recently published, goes further in detailing the relationship between exercise, diet, and metabolism. “There’s this expectation that if you exercise, your metabolism won’t drop as you lose weight or will even speed up,” Diana Thomas, a professor of mathematics at Montclair State University in New Jersey, tells the New York Times. Instead, she and her team measured that, if you are on a diet, your metabolism drops even if you are exercising every day.
The human body is incredibly efficient at conserving energy. Essentially, the Hazda don’t eat much so their metabolism is slow to counterbalance their higher energy expenditure.
Thomas says that current weight loss calculators don’t accurately factor in metabolic slow down and some even over predict based on exercise. Dr. Timothy Church of the Pennington Biomedical Research Center in Louisiana who oversaw the research adds, “It’s been known for some time that, calorie for calorie, it’s easier to lose weight by dieting than by exercise.”
The bottom line: while exercise has many important health benefits, it won’t significantly help you lose weight unless you cut calories.
Nothing like finding a few articles to light a bit of a fire under your bum.
Found this little gem surfing online yesterday and it definitely made me angry, angry enough to tell you about it..
This ‘blog’ the article above talks about is called Skinny Gossip and it’s the biggest piece of shit I’ve ever read. It gives girls advice or ‘thinspiration’ on anorexia, depression, eating disorders, self harm, etc. You name it, and this a-hole thinks they’ve got the answers.
I personally do not judge those around me, I was raised and taught better than that. Everyone you meet is dealing with their own personal battle. And I find this to be true. I know I’ve had many of my own personal battles, maybe just little issues comparatively speaking to those around me, but to each their own.
I understand she is in the spotlight and that’s what comes with her fame. I understand that everyone is entitled to their own opinions etc. That being said, I do not believe that justifies any of what this person says.
That’s why this little ditty blows my mind. This person needs to re-evaluate their life and should be stripped of their ‘freedom of speech’ because it more or less is garbage. I don’t think any human being should or has the right to talk about another person the way they do. Kate Upton is a beautiful woman, I do not think she is a cow or a pig, a squishy brick, etc. or whatever this creep described her as.
All I have to say is that Karma is a b*tch and these people should watch their P’s and Q’s.
