You can eat healthy and still be unhealthy.

Assuming you truly are eating healthy (vague concept, but I think we all have a decent grasp - donuts vs sweet potato - which is "better"?), it is still possible to be unhealthy due to, largely, over consumption. If you consistently over consume food, even if it is 100% "healthy" or "organic", you could still find yourself unhealthy. wedding bridal garments with v neck

I wouldn't say its common, as most "healthy" foods are not calorie dense, so over consumption in the face of tremendous satiety isn't something most people worry over.
