“#New book ‘Burn’ claims exercise won’t help you lose weight<\/strong>”<\/p>\n

You might feel the burn, but you won\u2019t see it.\u00a0<\/p>\n

\u201cWe\u2019ve all been told that the more active you are, the more calories you burn,\u201d said Herman Pontzer, an evolutionary anthropologist and Duke professor whose new book, \u201cBurn<\/a>,\u201d(Penguin) is out now. \u201cBut bodies aren\u2019t simple engines. We\u2019re evolved, complex beings,\u201d he told The Post.<\/p>\n

Pontzer, a Ph.D. who has spent his career studying energy expenditure among the Hadza tribe, a group of hunter-gatherers in northern Tanzania, claims that diet, and not exercise is the key to losing weight. <\/p>\n

By taking urine samples to determine their rate of carbon dioxide production, Pontzer found that although the Hadzas have a much more active lifestyle than their urbanite counterparts \u2014 members of the tribe hunt for food, while office workers eat Seamless at their desks \u2014 both expend roughly the same amount of energy.\u00a0\u00a0<\/p>\n

\u201cWe\u2019re on fixed incomes,\u201d Pontzer said of human physiology. \u201cWhen you spend more energy on physical activity, the body spends less energy in other places.\u201d<\/p>\n

In other words: While working out can have plenty of positive effects \u2014 reducing joint inflammation and building strength, endurance and mental sharpness \u2014 it won\u2019t do much to lower the number on the scale.\u00a0<\/p>\n

But not everyone agrees. \u201cI wouldn\u2019t go as far as to say exercise isn\u2019t important in weight loss,\u201d said Sean Heffron, a cardiologist who treats obesity at NYU Langone. \u201cExercise increases overall metabolism, which leads to further burning of calories, increases muscle mass and maintains lean tissue better, burning more energy in the long run.\u201d\u00a0<\/p>\n

\u201cIt\u2019s not quite as simple as calories in, calories out,\u201d said Cordelia Carter, a sports medicine specialist at NYU. \u201cBetter cardiovascular fitness and strength training prevents being \u2018skinny-fat\u2019 or \u2018fat but fit\u2019 \u2014 both of which aren\u2019t great.\u201d Heffron suggests high-intensity interval training to get \u201cthe most bang for your buck\u201d but agreed \u201cwithout a change in diet, weight loss is not going to happ<\/a>en.\u201d\u00a0<\/p>\n

\"Duke's
Duke\u2019s Herman Pontzer, PhD., says we can\u2019t lose weight from exercise alone in his new book, \u201cBurn.\u201d<\/figcaption><\/figure>\n

Pontzer argues that even our understanding of ideal caloric intake is wrong-headed. \u201cNine-year-olds burn 2,000 calories per day; for adults, it\u2019s closer to 3,000,\u201d he writes. In Pontzer\u2019s model of \u201cconstrained daily energy expenditure,\u201d our bodies adjust how we spend our capped number of calories based on lifestyle. <\/p>\n

A sedentary person\u2019s body will use energy for \u201cnonessential\u201d bodily functions, like amping up stress responses. For a star athlete, massive physical energy expenditure will draw away calories from other systems, such as reproduction and immunity. This can lead to excessive fatigue and burnout known as \u201covertraining syndrome.\u201d <\/p>\n

Pontzer has a surprising takeaway: \u201cYou\u2019re not in control of your metabolism,\u201d he said. <\/p>\n

That\u2019s why he believes the only way to slim down is through diet. The Hadza tribe\u2019s balanced, seasonal omnivore menu \u2014 with carb from grains, starch from tubers and sugar from honey \u2014 makes for a good example. He suggests eating protein- and fiber-rich meals that are satisfying and keep you full longer. <\/p>\n

As Westerners, he said, we get overly caught up in excluding entire categories of food. \u201cIf you villainize certain foods, you get to these weird conclusions like, \u2018An apple is bad for you because of the sugar content in fruit,\u2019 \u201d he said.\u00a0(One exception: processed foods, which Pontzer said, \u201cblows our brains up \u2026 by overwhelm[ing] our brain\u2019s reward systems.\u201d)<\/p>\n

He\u2019s also suspicious of trendy low-carb, low-sugar \u201cpaleo\u201d or \u201ccarnivore\u201d diets, which claim to mimic the diets of hunter-gatherer tribes. In reality, Pontzer said that the Hadzas are not nearly so strict about what they ingest. <\/p>\n

If your goal is to lose weight, Pontzer suggests reducing caloric intake by 3,500 calories per week, or 500 per day. He said this will result in weight loss at a rate of about a pound per week.<\/p>\n

\u201cUse diet to watch your weight,\u201d he said unequivocally, \u201cand exercise for everything else.\u201d\u00a0\n <\/p><\/div>\n
