So, we all know that dietary fats have had a long and infamous reporting of health claims made against them. Since the 1950s researchers and food scientists have been concerned with fats in your diet and how they may contribute to health problems, most notably heart disease. One such researcher – Ancel Keys – was very prominent in the 1950s and '60s in his belief that saturated fat can damage the arteries and along with cholesterol, cause heart disease.
Exercise has one purpose in mind; it is a stress to the body, which the body has to overcome. By adapting to this stress it pushes the metabolism through the roof, which will help with toning and fat loss along with increased cardiovascular and muscular fitness. There are numerous studies that indicate that high intensity training is more effective than traditional lower intensity training for increasing metabolic rate.
