I think that quote is a clumsy way of stating a valid concept. It's similar to Nick Norwitz's arguments against CICO. The idea is sound, but the phrasing is inflammatory and will upset those who don't properly understand it.
People don't become obese because they accidentally eat too much. They are well aware of how much they are eating as they gain weight. But there's an underlying compulsion that is difficult to resist long-term. It's as if there is a change in their metabolism that throws off their satiety mechanism, pushing them to overeat.
Here's one possible model:
Let's say food (carbs, fats, and protein) is fuel, and ATP is energy. Metabolically healthy people efficiently convert fuel into energy. But in metabolically deranged people, this process dysfunctions, and their cells experience an energy deficit. The brain interprets this as a fuel deficit (even when there is plenty available) and triggers a hunger signal that is stronger than necessary. This imbalance leads to obesity and/or diabetes over time.
The standard CICO explanation, which states that people "forgot" to eat less and are too lazy to exercise, sounds plausible, but does not align with the experiences of many obese individuals.
