A Review on Comparative Analysis of Weight Loss Diet: Efficacy, Safety and Clinical Outcomes

Abstract

Effective weight reduction and maintenance strategies are needed to enable people to make changes, as the prevalence of overweight and obesity is on the rise across the country and around the world. Studying the current data on effective diet plans for adult weight loss and maintenance was the aim of this review. Overall, an energy imbalance was necessary for significant safe weight loss, and this was usually achieved by consuming less fat. In this review, comparative analysis of various weight loss diet depending on their efficacy, safety and clinical outcomes are defined. For obese people, dietary restriction is a successful weight loss method. Daily calorie restriction (CR), which entails cutting calories by 15–60% of regular caloric intake each day, is the most often used type of dietary restriction. Compared to omnivores, vegetarians typically weigh less in surveys. Weight changes brought on by vegetarian diets, however, have not been accurately measured. We analyzed the impact of vegetarian diet suggestions on body weight. ketogenic diets, or VLCKDs, are a popular and successful weight-loss strategy. Because of the possible risks to renal function, physicians frequently view ketogenic diets, which are traditionally thought to be rich in protein, with concern. There is data that a Ketogenic diet can aid in regulating appetite, abdominal obesity, and weight loss. A combination of foods high primarily in antioxidants and anti-inflammatory elements makes up the Mediterranean diet, which is regarded as one of the best dietary patterns in the world. Multiple studies have shown a strong negative correlation between certain chronic diseases and a high level of adherence to the Mediterranean diet. The Mediterranean diet, or MedDiet, has been related to better cognitive health and a lower risk of cancer and cardiovascular disease, based on many studies conducted over many years.
