Sensible, of course. I once dropped basically all body fat (for an acting role) in about 5 months. I kept most of my muscle mass for the shoot, but I don't know how much longer I could have gone without losing that as well. I probably needed to consume more fat even than I did.
I was just told I am prediabetic (6.0 fasting). My BG has hovered between 5.5 and 5.8 for over a decade, but it just tipped the scale and my doctors are drawing attention to it. I have a relatively healthy diet, but I have never consciously cut carbs before. I work out nearly every day...
