Low-Carb Ketogenic, Atkins, Paleo Diets Aid Weight Loss, Fight Cancer: Eat Fat And Get Thin

Dietary fat has long been blamed for causing obesity and heart disease, but scientists say high-fat, low carb diets such as the ketogenic, Paleo and Atkins plans beat low-fat diets for weight loss and health.

A recent study from the National Institutes of Health suggests low-carb, high-fat diets (LCHF) are significantly more effective for weight loss and preventing heart disease than low-fat diets, Examiner reported.

Researchers at Tulane University tracked 148 obese men and women for one year. The subjects ranged in age from 22 to 75 and did not have heart disease or diabetes.

The participants were divided into two groups: One group followed a low-carb, high-fat diet that limited their daily carbohydrate intake to about 40 grams, or 28% of their daily calories. weight loss low carbThe low-carb dieters consumed about 40% to 43% of their daily calories from fat. Their daily menu was similar to the Paleo, ketogenic and Atkins diets, and included eggs, butter, fish, chicken and some red meat and generous portions of healthy fats such as olive oil.

In contrast, the low-fat group consumed 40% to 55% of their daily calories from carbohydrates, and their fat intake was limited to less than 30%

Low-Carbers Lost 3 Times More Weight Than Low-Fat Group

The results were dramatic: The low carb dieters lost about 12 pounds, while the low-fat dieters lost only 4 pounds even though both groups consumed the same calories.

What’s more, the low carbohydrate dieters lost more body fat and scored better than on a test that measured their chances of suffering a heart attack or stroke within the next 10 years.

Physician Dr. Lydia Bazzano, the lead study author, was stunned that a low-carb, high-fat diet could prevent heart disease better than a low-fat diet, which has long been prescribed for heart patients.

These results weren’t surprising to Jeff Volek, a leading low-carb researcher and professor at Ohio State University.

Volek, the author of The Art and Science of Low Carbohydrate Living, said high-carb diets cause blood sugar spikes, which fuel inflammation.

Inflammation is what causes weight gain, as well as diabetes, heart disease, Alzheimer’s disease and cancer. In contrast, unprocessed dietary fat has a negligible effect on blood sugar and insulin, which is why eating fat aids weight loss.

Jeff Volek of Ohio State University said the ketogenic diet curbs disease by reducing inflammation.

While the idea of consuming more fat may sound shocking given the low-fat diet mantra that has dominated the standard American diet (SAD), Volek said we actually evolved to thrive on a low carb, high-fat diet.

“For about 98% of human history, we’ve been eating low-carb,” Volek told Examiner. “We evolved in a state of nutritional ketosis.”

Low carb diets accelerate weight loss by forcing the body to burn fat for fuel, explained obesity expert Dr. Eric Westman, co-author of Keto Clarity.

LCHF ketogenic-style diets produce rapid weight loss, say experts.

Low-carb, high-fat diets such as the ketogenic, Paleo and Atkins diets promote rapid weight loss and boost health, say experts.

Dr. Westman, who has helped hundreds of morbidly obese people lose thousands of pounds on the high-fat Atkins, Paleo and ketogenic diets, said there’s no evidence saturated fat causes heart disease.

“The evidence for that has really disintegrated,” said Dr. Westman, director of the Duke University Lifestyle Medicine Clinic.

The American Heart Association now concedes that refined carbs such as sugar and flour are what cause weight gain, and it has backed off its longtime stance of recommending low-fat diets to prevent heart attacks. “We no longer think low-fat diets are the answer,” said Dr. Linda Van Horn of the AHA Nutrition Committee.

Many celebrities have also hopped on the low-carb bandwagon. Kim Kardashian lost 56 pounds on a low-carb ketogenic Atkins diet that limited her daily carb intake to less than 60 grams. Similarly, Tim McGraw lost 40 pounds after adopting a low-carb Paleo diet and is fitter than ever at age 48.

In addition to promoting weight loss, experts say the low-carb ketogenic, Atkins and Paleo diets can prevent Alzheimer’s. Groundbreaking research also suggests the high-fat ketogenic diet can treat cancer by starving cancer cells of the sugar they need to thrive.

“The ketogenic diet is a single metabolic approach to a multitude of different diseases,” said cancer scientist Dr. Thomas Seyfried, author of Cancer As a Metabolic Disease.

Thomas Seyfried’s decades of research show the low-carb ketogenic diet can treat cancer because cancer is a metabolic disease.

Seyfried, a pioneer in the nutritional treatment of cancer, said the ketogenic diet is the best treatment for glioblastoma (the most common and malignant form of brain cancer) because his research shows cancer is a metabolic — not a genetic — disease.

“The standard of care has been an abysmal failure for brain cancer,” said Dr. Seyfried. “The ketogenic diet can replace the standard of care for brain cancer, which is absolutely survivable through metabolic therapy.”
