getbulky saidI’d worry about definitions of “fit” you might be using (I see this as subjective in the same way as “healthy” is) but generally agree. Think the biggest problem with TBL is the metabolic damage you’ve referred to.

True! I agree that “fit” is really subjective (e.g. some people regard fitness as only cardio fitness, or leanness, or whatever). I think she’s super-strong and I know she Crossfits, so I reckon she’s fitter than your average person (saying that as someone who’s not a fan of Crossfit!)
