How to Diet While Keeping Kosher/Kashrut

Community Q&A

The kosher dietary laws were designed to preserve health standards. Unfortunately, kosher food can also be fattening, and you need to be careful not only what you eat, but how much.


  1. 1
    Talk to your doctor. Many nutritionists have dealt with people seeking to live by the laws of Kashrut and lose weight in the process. They can help you.
  2. 2
    See an Orthodox rabbi. Seeing that Kashrut is a Jewish concept, it would be a good idea to consult a rabbi before undertaking this mitzvah. The rabbi can figure out with you what "level" of Kashrut you would like to remain at while dieting.
  3. 3
    Join your local Jewish Community Center Fitness Program. Working out while dieting might not seem fun, however it will help you lose weight and gain muscle. Remember that there are also people doing the same thing that you are doing. Being around these people will help you concentrate more on your goal, and help boost your energy and drive.
  4. 4
    Choose your favorite activities and stick with them. Consistency is key. Continuing a single activity for two hours is better than doing four different activities for 30 minutes each. It will also make you feel good about yourself as you watch yourself improve at whatever activity you are doing.
  5. 5
    Are you going kosher or are you simply continuing to keep kosher? If you are starting to have a kosher diet, know the laws of Kashrut before you begin. The main rules are to not eat pork or shellfish, and to not eat milk and meat at the same meal.

  • When you go food shopping, you need to look for BOTH the kosher symbols and read the nutrition information.
  • Try to get friends and family to support you. Keeping kosher is no small feat. Dieting while keeping kosher is even harder. Make sure that you have a support system in place in the event that you falter.
  • Throw away any "nasty" foods. These foods include anything high in oil, fat, cholesterol, salt, sugar, and unnecessary calories. This can be especially hard for Jews around the Holiday Season. However, if you follow these tips, you'll end up feeling and looking better than ever before.


  • Even kosher diets can go wrong, so read the nutrition labels carefully when you go food shopping.
  • Diets can be dangerous. Make sure that you don't starve yourself or deprive your body of necessary nutrients. Knowing your limits is key.
