I am sure there is an exclusive deal with MyFitnessPal/UnderArmour to prevent Garmin allowing the direct entry of calories consumed.
Any ideas if/when this ends and Garmin might allow this? They've done it with Hydration, so why not calories.
Why? Because I hate having to find the brand of chicken I happen to be cooking and eating, or which brand of fruit juice I drink. I gave up on MFP years ago when all it seemed was a way of capturing data for advertisers. I know, to a reasonable accuracy, the calories I consume (too many, but that's a different issue) and I don't want to support personal data thieves.
