•if a human has not eaten in 6 days, o would blood glucose levels be high or low? o would ketones be in the blood? o would glucagon levels in the blood be high or low? o would insulin levels in the blood be high or low? o would the basal metabolic rate be higher or lower than normal? o would protein mass be increasing or decreasing?

If a human has not eaten in 6 days, 

o Would blood glucose levels be high or low? 

The answer is simple, your glucose will be dangerously high. 

o Would ketones be in the blood?

Yes, yes they would. 

o Would glucagon levels in the blood be high or low?

I am not exactly sure about this, but I know that when you haven't eaten your body prevents your blood sugar from getting too low by releasing glucagon levels. So I assume it'd be high?

That's all I can answer, Hope this helped
