Kelly Clarkson lost about 40 pounds by following a diet based on the best-selling book The Plant Paradox by Dr. Steven Gundry. The Plant Paradox diet is based on restricting gluten along with other types of “lectins” from your routine. Lectins are a type of protein that are present in foods such as nuts, vegetables, and fruits. The diet emphasizes wholesome sources of fats and proteins rather than a limited variety of plant food. Kelly Clarkson avoided lectins from her diet completely and further avoided foods that were high in sodium, such as processed and saturated foods along with reducing the consumption of cream and butter. The diet is expensive to follow because it avoids conventionally farmed poultry, dairy, as well as grain-fed meats. However, the diet is controversial, and some nutritionists are concerned about it. The foods you’re required to give up for the Plant Paradox diet are considered some of the healthiest, and avoiding lectins alone wont make you drop pounds. Therefore, it is important to consult a doctor or a registered dietitian before starting any new diet plan.
