All calories are equal as a unit of measurement, but their sources are not equal in their effects on energy expenditure and metabolizable energy.

“we must push back against the notion that all calories are created equal we know from studies of seed oils that seed oils linoleic acid containing oils are going to affect human physiology much differently than oils like tallow which contains stearic acid and other blood chain fatty acids so all calories are not created equally in the fats all calories are not created equally in the realm of carbohydrates”

“so all calories are not created equally and they're on the fat all calories are not created equally in the realm of carbohydrates”

“is a calorie a calorie thing yes all calories are equal because again calories are just a unit of measurement all sources of calories are not equal in terms of their effects on energy expenditure and metabolizable energy”
