It's vague, unmeasurable, and means something different to every person who says it.
"Eating healthy" can mean salad every day. It can also mean cutting out every food you enjoy while still being 400 calories under on protein.
The goals that actually work:
→ Hit 140g of protein today
→ Eat vegetables at 2 of 3 meals
→ Don't drink calories Monday–Friday
Specific. Countable. Done.
