CuriousJockAZ saidKey is to do cardio on an empty stomach, and no carbs at all after 6pm. Also, tell Ben & Jerry they need to find a new friend :-)
both myths and not backed up by any study whatsover
the only fact about the 6pm is those that tend to follow this philosophy just generaly eat less.
The reason our morning meal is called breakfast is because it literaly breaks the fast and fuels the furnace. As bodily functions continue to operate 24 hours your body needs fuel. By omitting additional fuel after 6 pm it means in effect the body will conseve what you have put in to last the night ahead. When the body is preserving like that less body fat is metabolised.
Studies actually show that to eat a wholegrain cereal based meal before bed can actually increase your fat loss potential as well as aiding restful sleep.
Fasted cardio on the other hand was a fad a while back and again its actually shown to help you lose weight not fat. Your body will primarily fuel this effort from glycogen stores not body fat.
