With summer fast approaching, it’s tempting to try and cheat our way into rapid weight loss. If you’re curious about meal replacement diets, it helps to understand how they work. Here are the benefits and drawbacks that you should know.

The year is 1977. The first SlimFast meal replacement diet enters the world, becoming the most popular selling weight-loss products. With celebrities such as Kim and Khloe Kardashian declaring similar products have helped towards their flat tummies, it’s unsurprising that meal replacement diets have been bought by millions. But how do they work and what are the advantages and disadvantages to using meal replacements?

What is meal replacement diet?

It’s what it says on the tin: a literal substitution for a meal that helps lessen our calorie intake to lose weight with very little effort required. Most diets of this ilk advise around 1,200 to 1,400 calories per day and have evolved from soups and shakes to various different meal replacement products. Today you can swap a main meal for smoothies, cookies, bars and crisps. 

How does a meal replacement diet work?

With most branded meal replacements, two of your usual meals are substituted with a meal replacement such as shakes, cookies or bars. Your main meal is a sensible choice of your own. In between your three main meals, you can have a few 100-calorie snacks to help ease hunger pains. Meal replacement diets also encourage at least 30 minutes of exercise per day as well as drinking plenty of water. Supposedly packed with your daily vitamin intake, there should be no deficiencies to worry about.

Meal Replacement Diet

Meal replacement diet: The cons

The meal replacement diet: Does it actually work?

With millions of people around the world turning to meal replacement diets for weight loss, it’s impossible to say that the diet doesn’t work. Here’s the science: by reducing your calorie intake, participating in 30 minutes of exercise and gulping ample H2O, you will lose weight more easily.

What we should question is the sustainability of this diet. For a short-term fix, its success is undeniable. But for a long-term weight-loss program, it’s always advisable that you eat a whole and balanced diet, making natural food a way of life rather than a rapid resolution.
