Brief Answer: Avocado high in calories leading to weight gain... Detailed Answer: Hi, Avocado is really high in fats, but the majority of them are healthy fats (monounsaturated) and little in saturated fats. Avocado is also high in calories, thus, its use is limited to 1/6 of medium avocado (2 tablespoon) per day. If you consume an entire avocado, and if it is of medium size, then, you are adding too much calories to your body. The excess of calories would lead to gaining weight. So, if you intend to gain weight through an avocado diet, then, can be an alternative. However, I always recommend to my patients to eat of all food types in order to take all the nutrients your body needs. Wish you health!
