In order to get into ketosis and remain there, limit your net carb intake to 20 grams per day. This means you’ll need to avoid many popular vegetarian protein sources, such as quinoa, buckwheat, legumes, and pulses. These foods are simply too high in carbs to be included on a ketogenic lifestyle. Also be sure to steer clear of milk and low fat dairy products, starchy vegetables, and fruits, other than perhaps a few berries.
Tossing everything in your pantry out all at once is a good way to waste money and cause a Ben & Jerry’s meltdown, but gradually replacing processed foods with fresh alternatives helps curb cravings and hunger, says Begun. “Highly processed foods are low in nutrients, causing the body to seek more food to find the nutrients it needs, which leads to a vicious cycle of overeating.” You don’t have to empty the pantry all at once, but slowly start making swaps like fresh fruit and yogurt for protein bars (which can contain as much sugar as a candy bar) or hummus and fresh veggies instead of nutritionally devoid pretzels.
A lot of this initial weight loss is water. Your fluid levels fluctuate often and can change dramatically when you alter your diet. For example, when you start a low-carbohydrate diet, you deplete the stored glycogen in your muscles. When you lose this glycogen, you also lose the water it retains. As a result of this loss of water weight, you may experience a flatter-feeling tummy and the first pounds lost on your scale. Lose just 2 cups of water, and it results in a pound lost on the scale, but it's not actual fat loss.
“I was 18 years old and 230 pounds. I was unhappy and realized after my freshman year of college that I needed to change my lifestyle. I come from a family of marathoners, but in 2012 when I told everyone I wanted to run my first marathon, I was told I couldn’t and wouldn’t do it—by family, friends, and even professors in front of my whole class. I took that adversity and have run the Marine Corps Marathon five years in a row, competed in six half marathons, and lost 83 pounds along the way.”
Vegetarians following the keto diet could also run the risk of becoming deficient in certain nutrients, vitamins, and minerals. Three big ones: B12, iron, and omega-3 fatty acids. "B12 is largely found in animal products; heme-iron, which is most readily absorbed, is only obtained in animal products; and fish is a great source of omega-3s," explains Sharp. Unfortunately, those aren't the only elements at risk of being deficient. Zinc, an important antioxidant, most often comes from meat and poultry; calcium and vitamin D—two nutrients that are crucial for bone health—are mostly found in dairy products; and magnesium, another important nutrient for bone health (and energy) is typically ingested via grains, which are on the no-no list for vegetarian keto followers.
You’ve heard that eating from smaller plates can help you eat less, but did you know that using a larger fork can do the same? A recent study by researchers at the University of Utah found that participants eating with a larger fork - one that held 20 percent more food—at an Italian restaurant ate about 10 percent less than those who used a regular fork. Researchers believe a smaller fork makes us feel we aren’t making as much of a dent on our plate so we’ll take more forkfuls to satisfy our hunger. (Note: This only worked with large portions. When diners were served smaller meals, fork size didn’t affect their consumption). So next time you’re order a super-sized entree, ask for a bigger fork to help you eat less. And while you’re at it, stop when you’re satisfied—not stuffed.
You may already be exercising, but adding Tabata training to your routine may help speed up your weight loss. ‘Tabata’ intervals are quick, 20-second bouts of heavy exertion (to the point where your breathing is very labored), followed by 10 seconds of rest—repeating the cycle a total of 8 times. Whether you jump rope, ride your bike or do other cardio, studies have shown this magic formula seems to help your body continue to burn calories long after you finish your workout, says Gretchen Zelek, co-creator of Do or Die Fitness.
The vegetarian diet is one of the best out there for weight loss; research has even found that it's twice as effective at reducing body weight than traditional low-carb diets. But as trendy diets pop up, vegetarians may want to expand their horizons. That's how the vegetarian keto diet, a variation of the super-popular ketogenic diet, started drawing attention.
If you’re longing for carbs so badly that you feel your resolve to stay on the diet is breaking, it’s possible to trick your brain that you’re eating them by making approved foods look more like your starchy favorites. Cauliflower can be grated into “rice,” or boiled and mashed like potatoes. You can slice zucchini into noodles to (sort of) replicate pasta. See “Vegan Substitutions for the Keto Diet” below.
You're more likely to see big changes in the number if you weigh yourself less often. Why? Because if you weigh yourself once a week, the result will be the total number of pounds lost over seven days. If you weigh yourself every day, you're likely to see small changes and you may even see weight gain. There are many different reasons that your weight changes every day and it is not always the result of how well you followed your diet.
