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).
Because different plant foods contain different types of amino acids, in excluding all animal products, vegans come to rely on a combination of grains, legumes, and seeds to get all of the essential amino acids their bodies need. Many of these foods are too high in carbs to be included on a keto diet, which is usually restricted to 20 grams of net carbs (total carbs minus fiber) per day. However, those who want to avoid all animal products can follow a lower-carb, non-keto vegan diet, such as the “Eco-Atkins” diet.
One of the more popular diets trending nowadays is the ketogenic diet. The diet requires you to reduce your carbohydrate intake and in turn, increase your fat intake. The aim of the diet is to get your body to use fat instead of glucose as energy and fueling your body until the next meal. Apart from weight loss, the ketogenic diet has been found to be helpful in managing blood sugar levels, reduces the risk of obesity, epilepsy, Alzheimer's disease, polycystic ovary syndrome and even some types of cancer. Some healthy foods to consume on a keto diet are starchy vegetables, coconut oil, cheese, sour cream, avocado, meat and poultry and high-fat dairy products. Reduce sugar and salt intake. Replace white sugar with palm sugar, jaggery or honey and salt with pink salt or black salt in cooking.
