Diet Types Review

There is no doubt that there are many diet types out there specifically designed for weight loss and maintaining fitness. Here we review some of the best varieties that have numerous health benefits. Let’s dive into it.



Flexitarian is the newest diet type of vegetarianism. It is a plant-based diet but flexitarians occasionally eat meat based products based on their personal choice. They are also known as flexible vegetarians, vegivores or casual vegetarians.

A flexitarian eats more plant-based foods. They try to incorporate fruits and vegetable juices into their meals such as homemade smoothies. Some flexitarians will have a meat-free meal once in a while but others will eat meat on rare occasions. Flexitarians should eat less meat. Those who eat meat occasionally should go for the best quality such as grass-fed beef, free-range chicken, wild-caught fish, etc. However, make sure to stick to small servings of animal products instead of large amounts of inferior meats and dairy.

Avoid eating processed meats like sausage, salami, and bacon. Too much-processed meat can be risky to your health.

Being a flexitarian has great health and nutritional benefits. By taking a small amount of nutritious and quality animal products in your diet, you get enough protein to provide the body with energy. You will also reap great benefits from plant-based diets that are cost-effective and low-risk interventions that help to reduce blood pressure and cholesterol levels. It is also a great diet for the family as it reduces spending on the overall grocery budgets.



The word “pollo” in pollotarian refers to chicken. A pollotarian or pollo-vegetarian don’t eat the flesh of red meat mammals but their diet plan includes white meat like chicken, fish, dairy, turkey and other poultry. They may or may not exclude fish, seafood, and dairy products from their diet, but the exclusion choice depends on tastes preference and ethical issues.

Some people will first try the pollotarian diet before becoming vegetarians. But there are those that just want to exclude red meat (lamb, beef, pork, venison) for health reasons such as to reduce heart disease and lower cholesterol levels.

Eliminating red meat from the diet have great health benefits. Poultry is considered heart healthy, so pollotarian will have less risk of heart disease compared to a person who consumes red meat. The diet is considered healthy with enough protein levels and low fat to keep your energy levels high and lower your blood sugar.



When people think of vegetarians, what comes to mind is lacto-ovo-vegetarians. It is the most popular type of vegetarianism. “Lacto” means milk and “ovo” refers to the egg.  Lacto-vegetarian refers to those who don’t eat eggs but eat dairy products, while Ovo-vegetarian describes the people who don’t eat both meat or dairy products but eat eggs. Lacto-ovo-vegetarian combines the two to form those who eat both eggs and dairy products.

A Lacto-ovo vegetarian does not eat beef, fish, pork, shellfish, poultry, or any flesh animal, but they eat foods that contain dairy products or eggs. Many lacto-ovo-vegetarians record an improvement in their health once they shift from meat-based diet to vegetarianism. They experience reduced cholesterol levels and reduced risk of heart disease since they consume eggs and dairy products. Similarly, since it excludes eating meat, this diet helps to improve the environment for animals.



A pescatarian diet is similar to the Pollotarian, only that they consume cooked fish and seafood instead of poultry. Also, pescatarian chooses to eat a vegetarian diet but also eats fish and seafood.

Pescatarians eat whole grains, legumes such as beans, tofu, lentils, and hummus; seeds such as chia, hemp, and flaxseeds; nuts and nut butter, fish and shellfish, eggs, fruits, dairy products (milk, yogurt, cheese), and vegetables.

On the other hand, Pescatarians don’t eat beef, turkey, chicken, wild game, lamb, and pork.

There are several reasons why people choose to omit meat and poultry but consume fish. Some prefer to include fish in their vegetarian diet to get more benefits of heart-healthy fish and plant-based diet. Other may be an effort to control the environment effect while for others, it’s just a matter of taste.

A pescetarian diet reduces the risk of heart diseases and other diseases such as obesity, high blood pressure, arthritis, osteoporosis, diabetes, including other types of cancer. It also helps in environmental conservation. Raising livestock is associated with high environmental cost but producing fish and seafood comes with low environmental effects with lower carbon emissions which reduces the risk for cardiovascular diseases.



The fruitarian diet is among the most restrictive plan. Being a fruitarian doesn’t mean you eat fruits only. Some fruitarians’eat only what falls from a plant. That is food harvested naturally without harming or killing the plant.  But the diet indicates that raw fruit should make up more than 75 percent of foods consumed.

A fruitarian diet includes fruits, nuts, and seeds. There are about five groups of fruits to choose from if you’re a fruitarian: acid fruits for example strawberries, citrus, pomegranates, and cranberries; sub-acid fruits for instance mangoes, apples, peaches, raspberries, blueberries, sweet cherries, and pears; dried fruits for example apricots and figs; sweet fruits like bananas and grapes; and oily fruits such as avocados, olives, and coconuts.  If you love nuts and seeds, you can choose from any variety.

Eating a fruitarian diet can result in weight loss depending on the type and quantity of fruits you consume. However, it can lead to nutrition deficiencies unless you ensure you get enough protein and fat levels in your diet. Fruits contain vitamins and anti-oxidants such as vitamin C and beta-carotene that helps reduce the risk of chronic disease and other types of cancer. If you choose to go on a fruitarian diet, proceed slowly and be sure to include vegetables, nuts, and seed in every meal.


More people have decided to go the vegan way for health, environmental and ethical reasons. Unlike vegetarians that eliminate meat, poultry, and fish, vegans go further to exclude all animal products including eggs and dairy.

Vegans substitute animal product with plant-based alternatives such as grains, legumes, seeds, nuts and nut butter, fruits, and vegetables. In addition, there are many types of food associated with veganism such as non-dairy milk substitutes, soy milk, tofu, seitan, and tempeh. There are also different vegan versions of foods available, so you can have vegan ice cream, hot dog, non-dairy yogurt along with vegan mayonnaise and veggie burgers.

Avoid eating any animal foods such as meat, fish, poultry, seafood, eggs, dairy products, and bee products.

If done right, a vegan diet may result in health benefits including weight loss and blood sugar control. Vegans may also experience fewer incidents of cancer or cardiac failure. Adopting a healthy vegan lifestyle can make a positive impact on the environment by reducing pollution, saving water and reducing land degradation.


Mediterranean Diet

The Mediterranean diet, also known as the Med Diet, reflects a traditional way of eating practiced by some counties around the Mediterranean. However, you don’t have to go all the way to the place. Just go to your local store and see the delicious flavors and fresh foodstuffs that make up the Mediterranean diet.

The Zone

The Zone Diet requires its user to stick to a specific ratio of protein (30%), carbs (40%), and fat (30%). It claims to reduce diet-induced inflammation in your body.

As part of the diet, proteins should be fat and lean which should be monounsaturated. Carbs should be mostly fruits and vegetables with low glycemic index. The right balance of protein, fats, and carbohydrates helps to control three main hormones –insulin, eicosanoids, and glucagon.

The Zone diet is similar to a Mediterranean diet with guidelines for taking three meals and two snacks per day. Each one contains a mix of low-fat protein such as turkey, fish or chicken; carbs such as veggies and fruits; and small portions of good fat like avocado, olive oil, and almonds.

No food is forbidden in this diet, but avoid eating fruits and vegetables high in sugar such as bananas, carrots, raisins, and corn; bad fats such as egg yolks and red meat; soft drinks; and other processed foods such as muffins and cereals.

The Zone diet helps to control insulin levels in the body which reduces dietary inflammation. As a result, it reduces the risk of severe gastrointestinal and digestive issues. It also prevents the onset of cancer as well as other serious illnesses.


Alkaline Diet

The Alkaline diet, also known as the acid-alkaline diet, promises to balance the acidity or alkalinity (pH levels) of the fluids in the body including blood and urine. The pH level in the body is identified by the density of minerals present in the foodstuffs you consume.

So when you eat food with acidic ash, your body becomes acidic. If you consume food with alkaline ash, your body becomes alkaline. Neutral ash has no serious effect. Acidic ash is considered harmful and may cause diseases, while alkaline ash is described as protective.

Most of the food we eat break down into either acidic or alkaline form. Foods that are considered acidic include protein, sulfur, and phosphate. Alkalines include calcium, potassium, and magnesium.

Meat, fish, grains, poultry, dairy products, and alcohol are more acidic. Vegetables, fresh fruits, nuts, and legumes are considered alkaline. Neutral foods include natural fats, sugars, and starches. It is important to maintain an alkaline based-diet and cut down on acidic foods.

There are claims that taking an alkaline diet can help reduce the risk of diabetes, arthritis, and certain types of cancer. The diet can also improve energy levels and memory loss as well as prevent you from heart disease, insomnia, headaches, muscle pain and bloating.
