A fuzzy approach for multi criteria decision making in diet plan ranking system using cuckoo optimization.

In recent days, people have easily adapted to unhealthy diets due to their busy lifestyles. Inappropriate and unhealthy food intake leads to various health problems. As a result of poor health and lack of information about a healthy diet, people depend on medicines rather than concentrating on improving their food intake. Due to the wide range of dietary advice, it is difficult to choose the appropriate diet plan that satisfies their personalized nutritional needs. The proposed system ranks the diet plan by considering personal information like age, gender, height, weight, pressure and heart rate. Various diet plans like intermittent fasting, plant-based diets, low-carb diets, paleo diet, low-fat diets, Mediterranean diet, DASH diet, vegan diet, gluten-free diet, GM diet and egg diet are considered. Multi-criteria decision-making methods such as fuzzy AHP and fuzzy TOPSIS are also applied for the decision-making process to rank the best diet plan. Fuzzy AHP is used for weight generation, which is given to the cuckoo algorithm for optimization, and then, the fuzzy TOPSIS method helps in ranking the diet plan. Personal information is considered as criteria, and the diet plans are considered as alternatives for the decision-making process. [ABSTRACT FROM AUTHOR]
