Avocados

Despite being frequently used and referred to as a vegetable, avocados are actually a fruit according to biology. Avocados are a great addition to a ketogenic diet due to their high heart-healthy fat content. Additionally, a 3.5-ounce (100-gram) serving of them has only 8.5 grams of net carbs and almost 7 grams of fiber. Avocados also include a variety of other crucial elements, such as potassium, folate, vitamin K, and vitamin C.

Its fat content is primarily monounsaturated (about 60%), with small levels of saturated and polyunsaturated fatty acids. Because of their amazing nutrient content, avocados also seem to be good for metabolism and heart health. Following an avocado-rich diet for a week reduced "bad" LDL cholesterol and triglycerides by 22%, while improving "good" HDL by 11%, according to one study in adults with high cholesterol.
