Low Calorie Diets or LCDs

Restricted calorie intake and strict dietary regimes, low calorie diets are used to lose weight and are used by many weight loss groups. What constitutes as 'low calorie' is relative to the individuals previous calorie limit without falling in to malnutrition. The body is supplied with nutrients however it is not enough to cover what is lost during the day.

The can be dangerous in some respects as a person may end up lacking necessary vitamins for good health and as such it always prudent to monitor food intake. Though there is risk, if good nutrition is kept (Calorie restriction with adequate nutrition or CRAN) then this particular style of dieting will quicken the process of losing weight.

Pregnant women and young adults are advised against using these kinds of diets, during pregnancy the extra calories that the body craves are imperative to a growing foetus and low calorie diets taken on by younger adults have the potential to develop into eating disorders, later in life.

  • Weight Watchers Diet
  • Body for Life
