People who eat too much may be using food to pour love into themselves.They are love starved. Eating food may be the only way they can accept Love. This is all very subtle and they may not even understand that this is what they are doing.
When someone tells someone else who is using food to love themselves, that they shouldn’t eat so much, they hear that they are not worthy to be loved. That is why it is such a charged issue. The more you try to help them stop eating, the more they are hearing that they are not worth being loved. It happens at a very subtle level.
