Cardio vs. strength help
Your diet may be clean and healthy, but also make sure you're counting the calories. Burn more than you consume. Meal timing also plays an important role. Eat your complex carbs earlier in the day when you need the energy, and stick to fibrous in the evening. You may also want to work on your protein/carb/fat ratios, as some are more sensitive to carbs based on body type. Also, you should do your lifting pre-cardio.
