My own personal experience has been that managing nothing but calories is the most successful approach by a mile, but that sticking to decent macros is the best way to manage my satiation and stick to my calorie budget. If you're managing satiety and glycemic index and ignoring calorie intake, you're not going to manage weight well. These are all tools in managing calorie inputs, not replacements for it.
