The first few days of switching to a ketogenic diet sucks. You'll feel hunger pangs, cravings, grumpy and probably suffer flu-like symptoms. You may even feel light-headed, sometimes. There are a number of reasons for this, including changes in gut biota, as various colonies are "screaming at you" for food, but mainly as your body initially will be looking for a quick glucose energy source, before switching metabolic states and preferring ketones, instead. This takes some patience and discipline.
“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.
