How to earn healthy badges like breakfast log ?

For Breakfast Club - Log at least one food item for breakfast daily for 7 consecutive days.

To get access to the nutrition functions you must have Connect+.

Go to your badges list and if they are in the 'available' section, then you could earn them. I have Connect+ so I don.t know if they are only for + but I doubt that. To earn them, you need to go daily and log your food and create meals in the Nutrition section and Hidration section in the More section in app or watch (I suggest the app as is faster and easier). One badge thow needs a food to be added from device (watch).

In Health stats section you log your weight and goal weight for some of these badges.
