"I'll pass on this intermittent fasting "fad" for now!" Presumably you've tried it ? That is to say, starting from a very high baseline of both cardio-vascular fitness and output as well as a high level of muscle training[1] you then tried IF and didn't notice a positive effect in your training or output ?
