What about diet soda or sugar free energy drinks? Well, considering these drinks use non-sugar sweeteners, they shouldn’t, in theory, knock you out of ketosis. Always check the nutrition label to make sure you’re not accidentally taking in some sugar. In addition to this, some experts predict that these sweeteners may increase your cravings for other sweets. Technically, though, these drinks should be fine for keto consumption. Let the buyer beware.
Protein - It is well documented that vegetarians supposedly lack protein sources. It is also well documented that vegetarians and vegans usually aren't deficient in protein at all. It is true, however, that vegetarian keto restricts some of the usual sources of protein for vegetarians, like beans, for example (except for these 1g net carb black soybeans).
Not only that, but increasing your intake of healthy fats and protein while reducing your intake of empty carbs can help ensure that you’re getting all of the essential nutrients that you need with none of the added ingredients and chemicals that you don’t. Studies have also shown that a higher intake of fat and protein can suppress your appetite and lower levels of ghrelin, the hunger hormone, more effectively than carbohydrates. (3, 4)
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.
Coconut butter comes in a jar as a solid substance, but when melted slightly in the microwave and mixed together, it has a taste and texture reminiscent of a frosting. In a room temperature environment, it becomes solid once again. Whether you simply enjoy it off the spoon, or as the icing on a keto cookie, this is one food that is not to be missed out on.
In this study, each experiment that tested a sugar alcohol against glucose was collected and grouped in order to find an average consensus. Notice that glucose's glycemic index is 100, which makes for easy comparison (table sugar is about 63, for example). As an example of the comparison, look at the first line of the table. You can see that 4 studies compared erythritol with glucose, and the studies found that erythritol had a glycemic index response of zero, on average. This means that of all known studies up to 2003, erythritol did not cause any increase in blood sugar. Xylitol, however, did increase blood sugar, but only has a glycemic index of 13. It is clear that sugar alcohols have some effect on blood sugar, the extent to which is unclear.
The middle section of the venn diagram shows foods that are suitable for a vegetarian keto diet. The first 3, however, are dairy and eggs, which are not allowed on a vegan diet. This is what makes vegan keto so difficult -- you are severely limited in the types of food you can consume, especially when considering that not all soy protein or "fake meat" is made vegan. It’s possible, it’s just really hard to do. If you’re feeling ambitious, here’s a short vegan keto guide that overviews some of the challenges and benchmarks for successfully doing vegan keto.
“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.
