The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
Mild calorie restriction may be beneficial for pregnant women to reduce weight gain (without weight loss) and reduce perinatal risks for both the mother and child. [11] [12] For overweight or obese individuals, calorie restriction may improve health through weight loss, although a gradual weight regain of 1–2 kg (2.2–4.4 lb) per year may occur.
The Estimated Energy Requirement, , is the estimated number of daily kilocalories, or Calories, an individual requires in order to maintain his or her current weight.For a person with a body mass of (kg), height of (m), age of (years) and Physical Activity , this is given by

The basal metabolic rate accounts for about 70% of the daily calorie expenditure by individuals. It is influenced by several factors. In humans, BMR typically declines by 1–2% per decade after age 20, mostly due to loss of fat-free mass, [3] although the variability between individuals is high. [4]
Dieting is the practice of eating food in a regulated way to decrease, maintain, or increase body weight, or to prevent and treat diseases such as diabetes and obesity.As weight loss depends on calorie intake, different kinds of calorie-reduced diets, such as those emphasising particular macronutrients (low-fat, low-carbohydrate, etc.), have been shown to be no more effective than one another.
A permanent severe deficit, on the other hand, which contains too few calories to maintain a healthy weight level, will eventually result in starvation and death. To reduce 1 kg (2.2 lbs) of weight, about 7000 kcal deficit is required.
Weight management generally includes tracking weight over time and identifying an individual's ideal body weight. [4] Weight management strategies most often focus on achieving healthy weights through slow but steady weight loss, followed by maintenance of an ideal body weight. [5]
