Maybe this should be in the cardio section but i figured it had to do with food too. Anyway. I know they say cardio in the morning is the best in terms of raising the metobalism and for fat loss. Would a glass of Orange juice 4oz and a cup of coffee with 1 teaspoon of sugar lessen the effectiveness of morning cardio due to the carbs they have. Wouldnt the caffiene have a positive effect.
