Welcome to the Forum!
Read through the first three threads in the Type 2 Section, when you get a chance, if you have not already done so. These threads will most-likely help you a lot. Self education is one of the keys to successful management of your diabetes, along with a healthy / sensible diet and exercise. Basically, diabetes requires a life-style change for the better. Good luck with your control and management.
Congrats on the weight loss!
Food input is addressed in the
"GB Help" thread.
Adding Foods:
The food entries are a bit different from the blood glucose entries. Under Add Logs; Food; Add Food; Add Log; Create a food called Carbs. (grams), then pick that food each time you input your food. This method is very simple and lets you keep up with your food by logging carbs. However, to effectively use this method, you will need to learn to carb count.
Try something simple first: Under Food; Add Food; Press + in the top right hand corner; Type in a name {I use Carbs. (grams)} and save the food. Then under Pick Food(s) you should be able to pick the food (when done successfully you will see a check mark on the right hand side), then press Add Log at the top left, this takes you back to Add Log menu where you should be able to input the grams.
