do you think there will ever be enough? calorie restriction is just one, very vague detail about input for human body; macro distribution, amount of fiber, amount of water and many more are just glossed over. total weight or even breakdown by tissue type on the other hand is a very simplistic measure of the "output". blood glucose, white/brown fat distribution, hormonal balance, basal metabolic rate, blood pressure and many more - all depend from long-term diet choices. it's like trying to train a nn by providing 95% random noise with input and not bothering to understand 95% of output. seems like taking everything into account is just too expensive.
