Apparently a low-fat diet isn't the healthy regimen we've believed it to be. When compared with low-carbohydrate and low-glycemic index diets, eating low-fat instead results in more insulin resistance, leads to the biggest decrease in the burning of calories, and causes unhealthy lipid patterns.
Even though Americans are eating 10 percent less fat than previously, more people struggle with obesity than ever before.
This was reported in a BMJ.com article written by Aseem Malhotra, interventional cardiology specialist registrar, Croydon University Hospital, London.
Part of the problem has been that when fat has been taken out of food, it is generally replaced with sugar. And sugar is increasingly being understood to be a far-reaching health hazard.
Sugar may be the single most significant factor in the risk for metabolic syndrome. This includes dysglycemia (abnormalities in blood glucose levels), high blood pressure, high triglycerides, low HDL (good) cholesterol, and unhealthy girth around the waist.
Dr. Christiane Northrup said in her blog that sugar causes inflammation and increases cardiovascular disease risk.
She pointed to low-fat foods that contain sugar instead of fat. In fact, sugar is found in many other foods, even some that you consider to be healthy. This includes some types of tomato sauce, fruit juices, salad dressings and yogurt.
So as you dutifully stick to what you have been led to believe is a healthy diet, you may be filling up on sugar.
When you think of a cheeseburger and french fries as an unhealthy meal, Northrup said, you may be thinking that the meat and cheese are the problems. But what if they're not? What if the problems are the buns, fries and the ketchup?
Northrup said that the February, 2014 issue of the Journal of the American Medical Association has reported that sugar is linked to dementia, heart attack and inflammatory disease like cancer, insulin resistance, liver conditions, reduced HDL (good) cholesterol and type 2 diabetes.
It causes cellular inflammation. And excess abdominal fat is the unhappy result of sugar, not fat consumption.
