A challenge that you may face is keeping your carbohydrates below 30 grams per day because by nature, these plant-based protein products contain 2-10 grams of carb per serving. But these products are also higher in dietary fiber (aka low-digestible carbs) which has a reduced effect on blood glucose levels (Grabitske, 2008). This may give you a little more flexibility with the number of carbs you can eat while still maintaining ketosis (e.g. up to 50 grams per day), but this will require tracking to be sure.
Walking is great exercise for weight loss, but it seems to be even more effective when done just after eating. A 2011 Japanese study found that walking immediately after a meal was more effective for weight loss than waiting up to an hour afterwards. Subjects who went for a brisk, 30-minute walk just after lunch and dinner lost more weight than those who waited to walk. And because walking is a low impact form of exercise, it shouldn’t cause any digestive distress.
Okay, I kid, but seriously. I have been skipping breakfast for as long as I can remember. I really only eat it on special occasions, if ever. It makes my calorie goals much easier to attain, and my body is totally cool with it. I don’t often wake up hungry. If you think you could handle waiting until noon to eat for the first time, give intermittent fasting a try. Even harder is to only do one meal a day, OMAD. This isn’t for everyone, especially if you get really hangry really quickly, but it is a great way to cut costs.
“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.
