Sadly, this doesn’t really address keto/low-carb, nor does it acknowledge the role that hormones play in how we metabolize foods. And given the outsize impact that has on what our bodies do with what we eat, one would hope they’d recognize the hormonal aspect (particularly insulin).
But it’s still an interesting read in the sense that even in the absence of a discussion of hormones, it largely blows up the notion that CICO (calories in, calories out) could ever be a useful tool for weight loss, because of the wide variance in how many calories our bodies are able to obtain from foods, depending on a range of factors from how the food is cooked or prepared, to our gut biomes.
It’s a good reminder that things are far more complex than the simple “eat less, move more” mantra would have us believe.
KCKO!
