For many vegetarians, beans and grains constitute a large portion of their daily protein consumption, so limiting them means you'll need to supplement your diet with something else. Smith suggests looking to "organic dairy or a low-carb protein powder that's plant-based" for meeting healthy protein consumption standards. Perhaps you could try incorporating low-carb Greek yogurt, nut butter, or whole eggs into your daily diet.
“The original keto diet is extremely high in fatty meats, which is not good for our cardiovascular system,” says Melissa Bailey, RD, creator of the Nourished Fork. “The vegetarian version eliminates these meats and allows for more plant-based options, such as avocado and nuts and seeds. In general, the population is going towards a more plant-based, whole-foods diet, which is why the ketotarian diet is emerging.” Luckily, you'll find that many of the best foods for weight loss are inexpensive, convenient, and easy to find in your local grocery store. When you learn how to plan and prepare meals in advance and fill your refrigerator with diet-friendly foods, you can even save time and money while you slim down.
