There is no Clear Requirement for Dietary Carbohydrates for Human Adults
The recent landmark study showed that a very-low-carbohydrate diet resulted in a significant reduction in fat mass and a concomitant increase in lean body mass in normal-weight men. Contrary to popular belief, insulin is not needed for glucose uptake and utilization in man. Finally, both muscle fat and carbohydrate burn in an amino acid flame.
Training in the fasted state improves glucose tolerance during fat-rich diet.
High-fat diet increased intramyocellular lipid but not diacylglycerol and ceramide contents, either in the absence or presence of training. This study for the first time shows that fasted training is more potent than fed training to facilitate adaptations in muscle and to improve whole-body glucose tolerance and insulin sensitivity during hyper-caloric fat-rich diet.
Fasted Cardio v Fed Cardio for Fat Loss
The researchers found that those who had exercised in a fasted state burned almost 20% more fat compared to those who had consumed breakfast before their workout. Furthermore researchers discovered that those who had exercised in the morning did not consume additional calories or experience increased appetite during the day to compensate for their earlier activity.
