It's hard for me to explain why the "calories in, calories out" theory is incorrect in so far as it's not useful to structure your diet around to prevent getting fat.

Gary Taubes was the person who I learned from the most, many years ago about high fat, low carb diet, and I have been following his advice ever since, to great success.

He has MANY videos on the internet, here is a recent one:

His book "Why we get fat" is also a great, clearly written explanation of all this, and I highly advise you to look into the subject, with an open mind. You may be surprised.
