I recommend against by completing the track with a food as "MyFitnessPal" => There are only like that you realize that calories "swallows". When you realize what it's like to have another bowl of cereal or take a pack of young schoolchildren to taste the weekend, it educates, even if it is binding.
The good news? The more you move, the more you can eat ;-) careful anyway.
The Fitbit and MyFitnessPal accounts can be linked, so the data is shared between the two applications and efforts translate into calories available for your meals.
In three weeks, I lost 2.5 kg !!!
Conclusion = great for someone just sports. A complete absolutely with food aid monitoring.
