I don't agree with this line of thinking. Without available carbs, the body is more vulnerable to catabolism. The body doesn’t burn your reserve (fat) stores first.The first source of fuel is to use up the stored carbohydrates. As long as carbs are present, there is little need to use fat. So you first have to burn the glycogen that is stored in your muscles. Then you get to burn fat. To be honest the best time to do cardio would be right after working out b/c the glycogen is already depleted from the muscles and the heart rate is already elevated and less activity will be required to achieve the desired effect. Now on the other side it doesn’t matter when you do cardio. Morning, noon or night doesn’t matter when. Your body doesn’t care about burning fat the only way to lose weight is to burn more calories then you consume. So that whole thing about “ you only burn the calories you ate that day” Well yeah no **** but as long as you are in a calorie deficit you will lose weight. Ok so when talking about losing weight we don’t wanna lose muscle. How do you avoid that?? Find out what you maintenance level of calories a day is and do a zig zag diet from there. So say your maintenance level is 3500 cal a day. You would do like 3 days at 3000 cal and then 1 day at 3500. That is the best way to trick your body into losing fat with out losing muscle.
