DIET BETTER FOR FAT LOSS
The most impressive low-carb study published to date in reference to health and body composition appeared in the journal Circulation in 2017. This diet study used magnetic resonance imaging (MRI) technology for the first time, measuring changes in body and organ fat during 18 months on a Mediterranean, low-carb diet. The Mediterranean, low-carb diet was significantly superior to a low-fat diet in decreasing fat storage, including visceral (deep abdominal) liver and heart fat. High visceral fat has been shown to increase metabolic syndrome, inflammation, cardiovascular disease and diabetes. A meta-analysis of 13 randomized controlled trials suggests that people on ketogenic diets tend to lose more weight than people on low-fat diets. In another 12-month weight-loss diet study, there was no significant difference found in weight change between a low-fat diet versus a low-carbohydrate diet (JAMA, February 20, 2018).
KETO DIETS HINDER EXERCISE PERFORMANCE
Unfortunately, ketogenic diets hinder exercise performance. New research from St. Louis University (Journal of Sports Medicine & Physical Fitness, April 2018) found that following low-carbohydrate, ketogenic diets impairs anaerobic exercise performance in exercise-trained men and women. Participants did not perform as well during anaerobic exercise in high-intensity, short-duration sports such as spr
