Reduced Caloric Intake

Despite what marketers have the public believing, weight loss does not require special pills or special foods. To lose weight, people need to reduce their caloric intake to less than their body needs, says the Harvard School of Public Health. A reduced-calorie diet is the key to successful weight loss.

Significance

People who have successfully lost weight and kept it off follow a reduced-calorie diet of about 1,400 calories a day, says the Harvard School of Public Health. A reduced caloric intake will lead to a healthier and longer life, says the Calorie Restriction Society.

Features

People who reduce their caloric intake by 500 calories a day generally will lose one pound a week, according to the American Academy of Family Physicians, although the best way to lose weight and keep it off is to reduce caloric intake by 250 calories and increase daily exercise to burn 250 more calories. Simple tips to reduce caloric intake include switching to skim milk, drinking only calorie-free beverages, snacking only on fruits and vegetables, and leaving a few bites at each meal.

Fad Diets

The different types of reduced-calorie diets include the low-fat diet, high-protein diet and even the high-fat, high-protein diet. As it turns out, each diet will produce weight loss, according to the National Institutes of Health (NIH). The macronutrient make-up of the diet does not matter--it is the overall calorie intake. The Harvard School of Public Health says people need to find the diet that works for them and stick with it.

Benefits

An obvious benefit to following a reduced-calorie diet is weight loss, as well as a decrease in body fat percentage, says the Mayo Clinic. A reduced caloric intake will also lead to a decreased risk of chronic diseases, says the Harvard School of Public Health. People who follow a reduced-calorie diet have lower blood pressure, blood fat levels and blood sugar. They also live longer, says the Calorie Restriction Society.

Warnings

It is recommended that people consult with a physician or registered dietitian before starting a reduced-calorie diet, says the Mayo Clinic. Diets need to be balanced and provide adequate amounts of vitamins and minerals. A severely restricted calorie diet with inadequate nutrient intake can lead to anemia, depression, fatigue and irritability.
