There are variety of diet plans available such as low-fat, low-calorie, low-carbohydrate diet plans, and one can also opt for high calorie diet plans to gain weight. Nowadays, with this increasing craze for diet plans, the market has came up with branded diet plans such as 'weight-watchers', 'Jenny Craig', and 'Atkins Diet.'
But mostly, these diet plans fail in providing the desired result. Jessica Bartfield, MD, internal medicine, who specializes in nutrition and weight management at the Loyola Center for Metabolic Surgery and Bariatric Care, in the US, has come up with four reasons behind the failure of diet plans.
The first reason is underestimation of the amount of the amount of calories consumed per day. Next reason is that typically a person needs to cut an average of 500 calories per day, and only exercising and having a diet plan is not enough to cut down those extra calories, it needs 60 minutes or more vigorous activity every day.
The third reason is failing to provide a steady stream of glucose throughout the day to the body, as this is required to maintain the optimal energy in the body, and to carry out metabolism. Finally, the people who sleep for less than six hours, produce a hormone 'ghrelin' in extra amount, and this stimulates the appetite, and in turn leads to weight gain, reported Zee News website.
