Hi -

Hope this isn't a silly question but:

A fresh raw Sainsbury's beef burger comes out of the packaging at 113.5g but after grilling, it's down to 77g. Although I haven't done the measurements, skinless chicken breast baked in foil does the same.

It would seem by the state of my grill pan (and the liquid I pour out of the foil the chicken's been baked in) that fat is being lost. Is it just fat, or are the carb/protein/calorie quantities affected by grilling or baking?

Thanks in advance.
