Your Health Today | We Are Shaped By Our Evolutionary History: For nearly a century, Americans have obsess with their weight. The proliferation of unconventional diets and intense exercise programs has made it impossible.

In addition, to separate the functions of nutrition, activity, calories, and metabolism in influencing weight gain. It ultimately boils down to “energy intake” against “energy expulsion,” according to most specialists.

The Duke University evolutionary anthropologist Herman Pontzer. The writer of the 2021 book Burn: New Research Blows the Lid Off How We Really Burn Calories, Lose Weight, & Stay Healthy. Also, gave a virtual lecture at Sigma Xi on January 25, 2022.

Our Species’ Fundamental Unseen Adaptation | Your Health Today

He was one of these experts. According to Pontzer’s presentation, studies of hunter gatherer tribes like the Hadza. That a Tanzanian community who receives its food by hunter gatherers.

Also, have given insight on how our genetic background effects the health we have now. He also debunks some of the most frequent misconceptions about weight reduction and metabolism.

Our species’ fundamental “unseen adaptation,” in his words, is our metabolism. Other primates of comparable stature do not expend as many calories as humans do.

Pontzer believes that this capacity evolved to enable not only hunting and gathering. Also qualities such as larger brains and longer lives, which he considers as “the center of what makes us human.”

The chance of developing metabolic syndrome (which can cause heart disease, stroke, and type 2 diabetes). Also, have increased as processed diets and increasingly sedentary lifestyles became the norm in many industrialized cultures. The first step to a healthier lifestyle is to learn how to discern fact from fiction when it comes to your metabolic state.

Myth 1: Workouts Enhance Metabolism

The Hadza walk 13,000-19,000 steps each day, significantly more than just the average American. The Hadza and other traditional communities burn approximately the same amount of calories per day as industrialized ones.

He argues this shows everyday energy use is limited. “Exercise limits your body’s energy expenditure.” Exercise promotes metabolism. The Hadza walk 13,000-19,000 steps each day, significantly more than just the average American.

The Hadza and other traditional communities burn nearly the same number of calories per day as industrialized ones. He argues this shows everyday energy use is limited. “Exercise limits your body’s energy expenditure.”

Myth 2: The Exercise Is Ineffective

Unless you lose weight, exercise is ineffective. Exercise may not accelerate your metabolism or help you lose weight, but it’s still healthy. We’re just beginning to comprehend how it affects every physiological system.

Pontzer thinks that limiting energy expenditure helps explain exercise’s anti-inflammatory, stress-response, and reproductive hormone effects. In his Q&A, he says lowering hormone levels lessens the risk of ovarian, breast, and prostate cancer.

Myth 3: Exercise Helps Shed Weight

Exercising is an excellent strategy to lose weight. Because our metabolisms don’t have much flexibility when it comes to energy expenditure. Also, it increasing your physical activity without changing your food will not result in considerable weight loss. “If you expend more calories, you have to consume more to restore them,” Pontzer explains.

Myth 4: Calories Are The Currency Of Life

Calories are irrelevant. “Life is a game of turning energy into babies. As well as, calories are the currency of life,” Pontzer says in reaction to this notion. He believes that the only thing which matters when it comes to reducing weight is calories.

Although we commonly associate weight loss with the optimal combination of exercise and food. The Pontzer claims that it is actually a result of burning more calories than you ingest, regardless of source of those calories.

Myth 5: Metabolism Doesn’t Decide Your Weight

Obesity is doomed by a slow metabolism. Although some people have a “rapid” or “slow” metabolism in relation to its size. Also, a slow metabolism doesn’t really result in weight gain: “Metabolism doesn’t decide your weight; it responds to it,” Pontzer explains.

Your genes have such a lot greater say in how much weight you battle with.” Almost all of the hundreds of gene variations linked to obesity are predominantly active in the brain, which is where feelings of fullness emerge.

Myth 6: Traditional Foraging Varies Widely

Humans evolved to consume a Paleo diet high in meat. Traditional foraging adaptations differ greatly. Although some traditional civilizations (such as Arctic groups) rely on meat, plenty of others (including tropical communities) do not.

According to Pontzer’s studies on Hadza nutrition and foraging tactics, meat provides a relatively modest fraction of their energy. They take a lot of carbohydrates, berries, fiber, and honey, just like people in many other traditional communities.

Myth 7:  Obesity Indicates Failure

Pontzer emphasizes that obesity isn’t anyone’s fault but rather a result of the meals we eat. Cheap, energy dense foods became more common in recent decades.

These foods lack fiber and protein, which tell the body it’s full. This leads to overeating. “It’s not personal failing, it’s how we’ve structured our eating settings,” he argues. If we wish to avoid metabolic disorders and obesity, we must address this.

In order to take back control of our own and society’s health, we must first understand the interplay and functions between food intake and activity, caloric expenditure and metabolism.

Spending more time outdoors with loved ones may also be beneficial, according to Pontzer’s observations regarding living in the Hadza community.
