> People aren't fat because they eat too much. People (and mammals) eat too much because their fat cells are being metabolically triggered by environmental and/or genetic factors to store fat at a higher than normal rate, diverting calories from operational needs, thus stimulating hunger.

Is hunger really the primary cause of overeating for those who suffer from obesity? This seems unlikely to me.

It's true that calin/calout is a simplification, but there are many who outright deny it. They may not be credible to you, but they are still powerful voices across all media and their gospel is happily accepted by many.

> What the people arguing against CICO are saying is that it's fucking stupid pointless advice to give to a population because while true it's not helpful. We know it's not helpful because we've been saying loud and clear it for many years and obesity rates have risen in almost every country every year.

Posts like yours that deride calin/calout as a useless oversimplification miss the mark; of course it's a very basic fact, not a treatment plan. It's crucial that people understand that this is the mechanism at play if they want to succeed at regulating their weight, and despite your assertion that "nobody credible denies it" there are a lot of big names who will sell you all kinds of solutions that ignore it, and focus on specific distractions rather than looking at obesity as a complex disease with many causes that lead to calorie surplus.
