The word diet comes from Old French diete and Medieval Latin dieta meaning “a daily food allowance”. The Latin word diaeta and Greek word diaita mean “a way of life, a regimen”.

According to Medilexicon`s medical dictionary, a diet means “1. Food and drink in general. 2. A prescribed course of eating and drinking in which the amount and kind of food, as well as the times at which it is to be taken, are regulated for therapeutic purposes. 3. Reduction of caloric intake so as to lose weight. 4. To follow any prescribed or specific diet.”In this article “diet” refers to a food and drink consumption regime with the aim to either lose weight, to prevent weight gain, or a lifestyle and philosophy.

We selected the most popular diets according to three criteria:

1. How many articles there are around about these diets/lifestyles.

 

2. How popular they seem to be generally.

 

3. How often we receive feedback on them.

Below you can see a list of the eight diets, a summary on each one, and links to specific articles about those diets.

Atkins Diet

The Atkins Diet, or Atkins Nutritional Approach, focuses on controlling the levels of insulin in our bodies through diet. If we consume large amounts of refined carbohydrates our insulin levels will rise rapidly, and then fall rapidly. Rising insulin levels will trigger our bodies to store as much of the energy we eat as possible – it will also make it less likely that our bodies use stored fat as a source of energy. Most people on the Atkins Diet will consume a higher proportion of proteins than they normally do.

The Zone Diet

The Zone Diet aims for a nutritional balance of 40% carbohydrates, 30% fats, and 30% protein each time we eat. The focus is also on controlling insulin levels, which result in more successful weight loss and body weight control. The Zone Diet encourages the consumption of good quality carbohydrates – unrefined carbohydrates, and fats, such as olive oil, avocado, and nuts.

Vegetarian Diet

There are various types of vegetarian – Lacto vegetarian, Fruitarian vegetarian, Lacto-ovo-vegetarian, Living food diet vegetarian, Ovo-vegetarian, Pescovegetarian, and Semi-vegetarian. The majority of vegetarians are lacto-ovovegetarians, in other words, they do not eat animal-based foods, except for eggs, dairy, and honey. Several studies over the last few years have shown that vegetarians have a lower body weight, suffer less from diseases, and generally have a longer life expectancy than people who eat meat.

Vegan Diet

Veganism is more of a way of life and a philosophy than a diet. A vegan does not eat anything that is animal based, including eggs, dairy, and honey. Vegans do not generally adopt veganism just for health reasons, but also for environmental and ethical/compassionate reasons. Vegans believe that modern intensive farming methods are bad for our environment and unsustainable in the long term. If all our food were plant based our environment would benefit, animals would suffer less, more food would be produced, and people would generally enjoy better physical and mental health, vegans say.

Weight Watchers Diet

Weight Watchers focuses on losing weight through diet, exercise, and a support network. Weight Watchers Inc. was born in the 1960s when a homemaker (housewife) who had lost some weight and was concerned she might put it back on. So, she created a network of friends. Weight Watchers is a huge company, with branches all over the world. Dieters can join either physically, and attend regular meetings, or online. In both cases there is a great deal of support and education available for the dieter.

South Beach Diet

The South Beach Diet was started by a cardiologist, Dr. Agatston, and a nutritionist, Marie Almon. It also focuses on the control of insulin levels, and the benefits of unrefined slow carbohydrates versus fast carbs. Dr. Agatston devised the South Beach Diet during the 1990s because he was disappointed with the low-fat, high-carb diet backed by the American Heart Association. He believed and found that low-fat regimes were not effective over the long term.

Raw Food Diet

The Raw Food Diet, or Raw Foodism, involves consuming foods and drinks which are not processed, are completely plant-based, and ideally organic. Raw Foodists generally say that at least three-quarters of your food intake should consist of uncooked food. A significant number of raw foodists are also vegans – they do not eat or drink anything which is animal based. There are four main types of raw foodists: 1. Raw vegetarians. 2. Raw vegans. 3. Raw omnivores. 4. Raw carnivores.

Mediterranean Diet

The Mediterranean Diet is Southern European, and more specifically focuses on the nutritional habits of the people of Crete, Greece, and southern Italy. Nowadays, Spain, southern France, and Portugal are also included; even though Portugal does not touch the Mediterranean Sea. The emphasis is on lots of plant foods, fresh fruits as dessert, beans, nuts, cereals, seeds, olive oil as the main source of dietary fats, cheese and yogurts are the main dairy foods, moderate amounts of fish and poultry, up to about four eggs per week, small amounts of red meat, and low/moderate amounts of wine. 25% to 35% of the Mediterranean diet consists of fat, with saturated fats not exceeding 8% of calorie intake.

The Advantages of Plant-Based Diets

The well known journal, Food Technology in October 2012 published a report explaining that plant-based diets either minimize or completely eliminate people’s genetic propensity to developing chronic diseases, such as diabetes type 2, cardiovascular disease, and cancer.
