MISTAKES
Yes, that is a common mistake.
"Knowing portion control but not following it is a bigger mistake than not knowing it."
You know what is healthy, but knowledge only helps when it becomes action. For people with diabetes, eating a large portion of healthy food can still raise blood sugar.
A simple life lesson:
> Knowledge without action gives no results.
Portion control + consistency = better health.
You could use this as a short quote:
"The biggest mistake is not lack of knowledge. The biggest mistake is knowing portion control and still ignoring it."
Or as a title:
"Portion Control: Knowing Is Not Enough, Following Is Everything."
