Scientist say a low-carb, high-fat ketogenic-style diet is better for weight loss, diabetes, and metabolic syndrome than diets focused obsessively on calorie restriction.
Obesity experts say the longstanding emphasis on calorie counting has failed, and we need to move beyond the "calories in, calories out" dogma if we're serious about defeating the global tsunami of obesity and diabetes. According to Ludwig, the true cause of weight gain isn't eating too many calories, but eating a high-carb diet that's rich in refined carbs. Ludwig join a growing list of medical experts who are dispelling the myth that eating fat makes you fat, and that calorie restriction is best for weight loss. Eating refined carbs like a 100-calorie pack of jelly beans (which are fat-free) produces a huge insulin spike that signals your fat cells to store calories.
You'll also feel fuller, longer, after eating the nuts, while the jelly beans will make your blood sugar surge and promptly crash, causing you to quickly feel hungry again.
Surges in blood sugar and insulin also leads to diabetes, inflammation and metabolic syndrome, so by curbing these with a low-carb, high-fat diet such as the Atkins and ketogenic diets, we simultaneously stem several diseases in one fell swoop.
Ludwig's JAMA commentary comes on the heels of new scientific research suggesting that unprocessed saturated fat is not the cause of weight gain, diabetes or heart disease. What fuels weight gain and disease is inflammation — which is caused by a high-carb diet — especially one high in sugar, said Dr.
The irony is that the foods we were taught are good for us — breads, cereals, pasta, rice, potatoes — are the very ones that are killing us, said Westman. Westman has been aware of the health benefits of dietary fat for years and is glad there's a growing vindication of this important macronutrient. Studies show the ketogenic diet is better than drugs for managing epilepsy-induced seizures, can reverse type 2 diabetes, and manage cancer.
Volek, author of The Art and Science of Low Carbohydrate Living, is encouraged by the increasing popularity of high-fat diets like the ketogenic diet, as more people are beginning to accept that eating fat does not make you fat. Saturated fat is not the cause of weight gain, diabetes or heart disease, according to scientific research touting the benefits of high-fat, low-carb diets such as the ketogenic, Atkins and Paleo diets.
The true cause of obesity, cardiovascular disease, high cholesterol and diabetes is a high-carb diet, especially one high in sugar.
In 1958, Keys proclaimed that a high-fat diet caused cardiovascular disease after concluding that the nations with the highest rates of heart disease consumed the most fat.
Later analysis revealed that Keys had cherry-picked his data, leaving out countries where people ate a high-fat diet but did not have heart disease, as well as countries where heart disease was high despite a low-fat diet.


But a sea-change is afoot, as more medical experts reject the low-fat diet dogma promoted by Conventional Wisdom and underscore the health benefits of low-carb, high-fat diets such the ketogenic and Atkins diets. By drastically reducing carbs in our diet and replacing them with healthy, unprocessed fats, Dr. Low carb diets such as the Atkins, Paleo and ketogenic diets fuel rapid weight loss by forcing the body to burn fat fuel in a metabolic state called ketosis, said Dr.
Because dietary fat has a negligible impact on insulin, it doesn't produce surges in our blood glucose and insulin the way carbs do.
While the idea of consuming more dietary fat may sound shocking given the low-fat diet mantra that has dominated SAD (the Standard American Diet), Dr.
Eating more healthy fats and fewer carbs also has neuroprotective benefits, said neurologist Dr. Teicholz, a former vegetarian, has seen the positive impact a low-carb, high fat diet has had on her own health. Teicholz echoed the sentiments of science journalist Gary Taubes, who argued that fat has been wrongly blamed for obesity and other diseases for the past 40 years.
Low carb diets have become increasingly popular as evidence mounts that they are more beneficial than low-fat diets.
Multiple studies have shown that high fat low carb ketogenic diets can boost weight loss, and the most well-known plan is the Atkins diet. David Ludwig, director of the Obesity Prevention Center at Boston Children’s Hospital, wrote in JAMA. This is because our body stores fat when we experience insulin spikes, which are caused by eating too much sugar and processed grains like white bread.
The way to lose weight is to prevent insulin spikes, which the LCHF Atkins and ketogenic diets do.
Eric Westman champions a low-carb, high-fat ketogenic-style diet for weight loss and reversing type 2 diabetes. Westman said eating a diet high in healthy fats such as olive oil, whole eggs, grass-fed beef, and pastured butter not only accelerates weight loss, but reduces inflammation. For people who want to lose weight without deprivation and enjoy optimal health, Westman wholeheartedly champions a low carb, high-fat (LCHF) diet.
Volek has followed a ketogenic diet for the past 20 years, and credits it for his excellent health.


Volek explained that by drastically reducing carbs in our diet and replacing them with healthy, unprocessed fats, we boost fat-burning, eliminate nagging carb cravings, experience more stable blood sugar levels, and enjoy better mood. A graduate of the University of Pennsylvania, Samantha enjoys running, cycling and photography.
She said the longstanding belief that saturated fat is unhealthy stemmed from flawed scientific research, namely from the Seven Countries Study conducted by vegetarian scientist Ancel Keys. Jeff Volek, a professor at Ohio State University, is a pioneer in the low-carb, high-fat diet movement who said a LCHF diet promotes optimal health, for both elite athletes and the average sedentary individual. Volek said we accelerate weight loss, boost fat-burning, experience more stable blood sugar levels, and ward off degenerative conditions such as heart disease, obesity, dementia, and diabetes.
More importantly, unprocessed fat does not fuel inflammation, which causes aging and leads to obesity, heart disease, diabetes, Alzheimer's and even cancer. Dominic D'Agostino recently told me the LCHF ketogenic diet has proven more effective than drugs at managing epilepsy-induced seizures. She said she struggled to lose weight on low-fat diets, but was able to shed 10 pounds without exercise simply by increasing her consumption of healthy fats and reducing her carb intake.
Volek is confident more people will embrace the low-carb, high-fat eating plan and seize control of their health through diet. Sugar raises insulin, which causes inflammation, which is the fundamental cause of heart disease.
Restricting carbs allows the body to use stored fat for fuel rather than the limited fuel obtained from carb intake, he told me. Volek doesn't have a weight problem, but follows the ketogenic diet for its many health benefits, which include reduced inflammation, improved mood, and protection from diabetes and heart disease. Dominic D'Agostino told me the ketogenic diet can prevent and treat metastatic cancer because cancer is a metabolic disease, and cancer cells thrive on sugar.
What's more, the ketogenic diet can prevent and manage cancer because cancer is a metabolic disease, and cancer cells thrive on sugar. According to Perlmutter, we can prevent — and even reverse — dementia, ADHD and Alzheimer's disease by following a low-carb, gluten-free Paleo diet.
