A preacher the other day said something similar to this that made me think -

People are constantly complaining about the churches they go to because they do not feel like they are being fed. According to said preacher, it's one of the main reasons why people change churches - they feel like they're not growing at all and are stagnant. While it may be so that these people aren't getting what they need, it also may be that these people aren't using the food they're being given. Most people who are fed will not be healthy if they lie around and are stagnant lazy bums who don't exercise. The same goes for spiritual food - in order to truly grow and become healthy you need to exercise what is being given to you, apply it so you can grow and become stronger in your faith. It's no good letting the food sit in you, eventually turning into fat and adding weight to your body. We'd all be obese people if we let that happen.
