“an erlicher yid eats for one reason only, he eats so that he/she can have strength to serve Hashem.
There are many ways one can eat Lshem Shamayim that don’t involve fooling yourself.
1) Eat food that is healthy and avoid impulsively eating foods in quantities that compromise your health and be mikayem the Mitza of guarding your health.
2) Eat mindfully, actually appreciating the pleasure and nutrition that the food is bringing you. Express that appreciation to the One who provided the food by making the brachos with kavanah. You can also be mkayem the Mitzva of Ahavta L’Raecha Kmocha by intending that your bracha should increase the sheffa of bracha to all of Klal Yisroel (see Nefish HaChaim regarding meaning of the word baruch).
3) Take your wife out to lunch or dinner. Take your kids (one at a time) out for ice cream. Making time for those close to us and shared PLEASURABLE experiences should be common and are an important ingredient in Shalom Bayis and effective Chinuch.
4) Appriciating that for every food that Hashem assured there is a comparable food which is permissible. This is a Chazal.
5) Put aside the best foods lkavod Shabbos, Vkarata Lshabbos Oneg.
