Given that all participants in the study were overweight and “healthy”, what was not studied, and could have been very useful, was what was the impact of the two diets on participants’ blood sugars (HbA1c), insulin levels, and on some measure of inflammation. It is possible that there could have been little difference in weight loss between the two diets but big differences in the impact on risk factors related to diabetes.
"Only doing abdominal-focused workouts, like crunches, won’t help you banish the bulge. Belly fat is simply where your body stores energy, so you need to take a whole-body approach to tackle it. HIIT training (high intensity interval training) is a great way to burn fat and get your heart rate up. Squats, burpees and treadmill sprints are all examples to try."
