I didn't know strawberries were considered to have negative calories. I've heard of celery being like that though. I think they take more calories to consume than are actually in them. I'm trying to eat a lot more raw foods and fruits/vegetables. Also I take fish oil and coconut oil.
Sometimes it's hard to eat healthy so I'll put fruits/vegetables/nuts/protein power in a blender to make sure I'm getting all the nutrients I need.
Great post man, thanks for reminding me about drinking enough water, I need to get a water jug and start drinking water in the mornings.
