Meal Replacement Diets

By Mizpah Matus B.Hlth.Sc(Hons)

Meal replacement diets come in all shapes and sizes often being marketed with amazing testimonials about how easy they are to carry out and how much weight can be lost.

While weight loss is definitely possible with meal replacement programs it may not be as easy and enjoyable as celebrities or past users make it seem.

Meal Replacement is often more appropriate for those that require extreme weight loss.

Meal Replacement Diet Basics


The basic premise behind the theory of meal replacement:

  • The dieter switches out two meals a day with products that are designed to curb appetite and that reduce their caloric intake.
  • The dieter is then encouraged to eat a portion controlled, healthy dinner.
  • Meal replacement products are usually in the form of shakes, soups, bars, cookies, and drinks.

Basically meal replacement diets are very low calorie diets in that the average calorie intake is only between 800 and 1000 calories a day.

This is why many can achieve such fast results with these programs.

Are Meal Replacement Diets Safe?

As with any new diet, it is important to consult your physician before beginning a meal replacement plan.

Some plans are medically supervised because of the risks involved in a very low Calorie Diet. However, if these programs are done correctly, they are generally safe. It is usually people with underlying health problems or people who do not adhere to the meal replacement program guidelines that have problems.

These products can be expensive and many gain the weight back after they quit using the products because the dieter hasn’t learned to adjust portion size or hasn’t addressed the underlying emotional causes of overeating.

Another negative aspect of these programs is that the meal replacement products are often highly processed.

Do your homework before choosing a meal replacement diet in order to find one that’s healthy and best for you.

      Meal replacements are proven to work, but you have to learn how to eat healthy and readjust your proportions so that when you finish, you don’t regain the weight.

    Dieting is hard so I think that its ok to give yourself a good kickstart, with maybe the 3 day diet and then try and maintain good eating habbits after you have reached your goal weight.

  • Pearl

    One very popular one u missed out is Cambridge Diet. It is exactly the same as Lighter Life but its been around since the 80′s apparently. It works to perfection but it is the hardest diet u will ever come across. it needs discipline and determination. but it works and u lose about a stone a month. Its also very simple and convenient

    I use a meal replacement shake twice a day. I replace breakfast and lunch with the shake, and eat two healthy snacks a day and a healthy dinner. This has really changed my life. I am at my ideal weight and have been able to keep it off.

    • charlotte

      what kind of meal replacement?

  • Courtney

    Meal Replacement Diets, including the ones you quotes, are NOT very low calorie diets at all. Generally, proper use of them involves consuming between 1400 and 1600 calories per day, as it states in the directions for use. Usually, one would have 2 shakes/bars etc, 2 or 3 100 calorie snacks, and a 600 calorie meal, which in no way constitutes a VLCD.
