Carbs can be your worst enemy if you’re trying to lose weight.

The Today show recently shed light on a perspective that suggests the key to weight loss is more about cutting carbs than worrying so much about balance. calories we eat and burnaccording to an article published last December in the American Journal of Clinical Nutrition.

“The body fights against calorie restriction,” lead author Dr. David Ludwig said, “Today.”

Limit calories makes people hungrier, but also slows metabolism, according to the show.

“So there aren’t too many calories in the blood. There are too few.”

The popular keto diet is a low-carb, high-fat diet that puts your body into ketosis, the process in which your body burns fat for fuel, rather than carbs.

When our bodies produce too much insulin, fat cells are programmed to store calories, he explained.

Ludwig, endocrinologist and professor of pediatrics and nutrition at Harvard Medical School, advocates for the “carb-insulin model” of obesity.

The pancreas produces a hormone called insulin to control the amount of sugar, or glucose, in our bloodstream where it functions as a “key” to help glucose enter our body’s cells, according to Healthline.

Ludwig suggests that our way of thinking about weight loss is backwards.

“Given the choice between bread and butter, for years we focused on eliminating butter,” Ludwig said.

“But maybe between the two, the bread is the bigger problem.”


He says it’s not so much that eating too many calories leads to weight gain, but the high sugar content of some carbohydrates causes our bodies to store too much energy, causing us to eat even more.

We begin to build fat stores when the calories we ingest exceed the calories we can burn over time, said Dr. Karl Nadolsky, an endocrinologist who specializes in diabetes, metabolism and obesity.

“The whole world thinks obesity is a matter of energy balance,” said Dr. Robert Lustig, a professor of pediatrics in the division of endocrinology at the University of California, San Francisco, who described a similar pattern. excess insulin leading to weight gain in 2006.

“Therefore, it’s about calories in, calories out. Therefore, it’s about two behaviors, greediness and laziness. Therefore, if you’re fat, it’s your fault. Therefore , diet and exercise.

Ludwig and his co-authors note that the energy balance theory that people consume more than they burn explains why people gain weight, but it’s the “why” that isn’t addressed. .

“The common recommendation, ‘eat less, be more physically active,’ that we tell people isn’t working very well. The results aren’t so successful,” said Dr. Samuel Klein, director of the Center for Human Nutrition at the University of Washington. St. Louis School of Medicine.

But Ludwig’s article has sparked controversy in the medical community, with researchers “defending and ridiculing” the article, according to MedPage Today.

“If weight loss were as simple as eating fewer carbs, you’d think two-thirds of Americans who diet each year would have been successful by now,” said Dr. Yoni Freedhoff, associate professor of family medicine at the University. University of Ottawa. and medical director of the Bariatric Medical Institute, a non-surgical weight management center.


Nevertheless, significant research on weak carbohydrate diets is currently underway and is providing tangible results for some patients.

Dr. Jeff Volek, a registered dietitian and professor in the Department of Human Sciences at Ohio State University, who has studied low-carb diets for more than 25 years, told “Today” that research shows people on a low carbohydrate diet can lose 10% of their body weight.

And people remember it.

The show highlighted one of its patients, a 42-year-old woman, who enrolled in a study on a low-carb diet in 2019, containing 37 grams of carbs a day, which was also high in protein and healthy fats, such as avocados and nuts. .

In six weeks, she lost 20 pounds, but now, three years later, she’s lost a total of 88 pounds.

She told ‘Today’ that it “wasn’t easy” to give up her favorite foods at first, like pasta and potatoes, but the results are worth it.

“When you restrict carbs, the body becomes really good at burning its own body fat because it doesn’t have a lot of sugar to burn for fuel,” Volek said on ‘Today’.

Volek told Fox News why low-carb diets often fail.


“The vast majority of adults in the United States (well over 100 million people) eat too many carbohydrates than their tolerance, which is why low-fat diets don’t work for most people. A strong body of research demonstrates that reducing carbs is a safe, effective and sustainable approach to improving weight and metabolic health,” he said.
