<The biggest problem is that most people grossly underestimate how much they are eating and overestimate how many calories they are burning through physical activity.
There is a British show on YouTube called ‘Secret Eaters.’ It places cameras in the homes of people who swear they don’t eat ‘that much’ and don’t understand why they can’t lose weight.
What they don’t tell the families is that they send private detectives after them and film and buy all the same stuff the family members buy or have at work (like left over donuts in the office kitchen).
People forget that they stopped for food on the way home, that they ate after going to the gym, or that they nibbled the whole time they were making dinner. It was fascinating.
One thing about the Brits, they sure like to drink. Many of the people would lose weight instantly if they cut out the constant drinking - and because they drink with their meals, lunch and dinner, it is easy to lose track of how much one is drinking. It’s worth a watch.
