The Kosher Diet follows the kashrut, dietary laws as explained in the Torah, and is a tenant of the Jewish faith. When following the diet to lose weight or maintain a healthy weight, you can easily do so by counting calories and trying to balance your meals.
However, it’s essential that you avoid certain foods, for adherence to the kashrut and to help keep the diet healthy. Just remember that if you choose this diet for spiritual reasons, your food must be certified by a rabbi during production, so look for the heksher symbol that certifies this.
1. Pork Products
Eating pork products is forbidden according to the Kosher Diet, so eliminate anything made from pig, including bacon, ham, some sausage, and any food that may include pork grease or fat, such as gelatin that hasn’t been certified as kosher. As foods like bacon and sausage are among the most unhealthy meat products, this is helpful for your goal to achieve or maintain a healthy weight as well.
2. Some Poultry
Most kinds of fowl are not acceptable according to the kashrut, so it’s easier to list the poultry that is acceptable: chicken, duck, goose and turkey, which are at least among the leanest and most readily available kinds of poultry.
It may seem appealing to turn to alternative sources of meat, but rabbit is also forbidden according to the kashrut. Instead, choose lamb, goat, bison or beef. These foods must be slaughtered by a shochet, a kosher butcher, and salted with kosher salt, which is actually slightly lower in sodium than traditional salt, so this is a plus for your heart health.
4. Some Seafood
Most fish is okay with the Kosher Diet, but seafood without scales and fins, such as shrimp, lobster and other crustaceans and shellfish, are forbidden. Other fish you must avoid include catfish, eel, sturgeon, monkfish and dogfish.
Cheeseburgers are perhaps the most obvious example of mixing dairy with meat in one meal, which is forbidden according to the kashrut. (This also includes having a glass of milk or any dairy product in the same sitting you eat meat.) Cheeseburgers are high in calories and saturated fat, anyway, so you should avoid them in a healthy diet.
6. Most Ice Cream
While there are some low-calories ice creams that can help satisfy your sweet tooth, you must also be careful to buy only kosher ice creams. Most ice creams involve the mixing of dairy and animal products (like gelatin).
7. Some Yogurt
Yogurt can be a healthy snack to curb hunger without adding a lot of calories, carbs or fat to your diet, especially if you choose the plain varieties without added sugar. But many types of yogurt are non-kosher because animal and dairy products are mixed during their production. You can, however, seek kosher yogurt.
8. Some Fruit and Nuts
While fruits, nuts and other foods from trees are usually allowed in the Kosher Diet, you can’t choose just anything you find. Look for the heksher, as any food from a tree can only be harvested when the tree is at least 3 years old.
