Let's define "lustful eating": lustful eating means that we eat when we don't need to, either out of boredom, compulsion, as a means of trying to console ourselves or as source of recreation, when we strive to satiate our bodily appetites with no regard to our spiritual and physical health. Lustful eating is the opposite of healthy eating. The three main types of lustful eating are eating unhealthy foods, overeating and binge eating. Lustful eating is not only detrimental to the body, but to the soul as well, as we'll soon see.
According to the Rambam, lustful eating the #1 cause of all disease, even the nasty big C, the disease that won’t don’t even like to mention by name. Lustful eating also creates an iron curtain between a person and Hashem. So, a person can’t possibly get close to Hashem until he or she overcomes their lust for eating. These are not my words, but the words of Rebbe Nachman of Breslev.
Western society’s preoccupation with pleasure seeking and appetite fulfillment is fertile ground for lustful eating, but it's not the root of it. The root, as many psychotherapists will tell you, is a low self-image. A person who can't see his or her own self worth will suffer from being overweight and out of shape, but they won't go past a mere one-time paltry effort because they don't believe that they are capable of succeeding in getting into shape. I see this time and again in my clients; just as important as teaching them healthy eating habits and exercise, I work with them on their self image. Nine out of ten people with weight and fitness problems, in my experience, had or have an abusive parent who robbed them of their feeling of self worth from a tender age. Let's go deeper.
In Likutei Moharan, Part 1,Torah 47, Rebbe Nachman says: “One who is entrenched in the lust for eating is far from the truth, and severe judgments hover over him."
The lustful eater encounters Rebbe Nachman's above teaching and protests vehemently: "What, is Rebbe Nachman calling me a liar, just because I'm into the cookie jar more than I should be or just because I down a pizza with a couple cans of cola?" Cherished friend, if you eat like that, you can't possibly care too much about yourself. What's even worse is that you're unaware how much Hashem cares about you, loves you and wants to be healthy. What's worse yet is that you don't believe how much Hashem cares about you, loves you and wants to be healthy. Sorry, but in that respect, the lustful eater is far from the truth.
Hashem loves you - guaranteed - and He wants you to love yourself. All the negative comments that the abusive person in your life made when you were little were the biggest lies in the world. Tell yourself over and over how much Hashem loves you; say it to yourself a thousand times a day. Once you internalize it, the distance between you and looking and feeling your best is much much shorter. Hashem loves you - I promise. G-d bless for your good health!
