Beginners Guide to Popular Diets 


Dieting strategies are methods that people use to manage their food intake to achieve weight loss, weight maintenance, or improve overall health. There are many different dieting strategies, and some work better than others depending on an individual’s needs, lifestyle, and preferences.

Some popular dieting strategies include calorie restriction, which involves reducing the number of calories consumed to create a calorie deficit and promote weight loss. Another approach is macronutrient manipulation, which involves adjusting the number of carbohydrates, proteins, and fat in the diet to achieve weight loss or gain. Intermittent fasting is another popular dieting strategy involving cycling between eating and fasting periods to reduce calorie intake and promote weight loss.

While these strategies can be effective, it’s essential to approach them with a balanced and sustainable mindset, taking into account factors such as individual nutritional needs, activity levels, and overall health.

In this blog, we will be discussing the following popular diets

  • Intermittent fasting
  • Paleo diet
  • GM diet
  • Keto diet
  • Mediterranean diet

Intermittent Fasting

Intermittent fasting (IF) is a dietary pattern that involves alternating periods of fasting and eating. 

There are several methods of IF, but the most common ones are as given below

  • Time-restricted feeding (TRF)- This method involves fasting for a certain number of hours per day and eating within a specific window of time. For example, one may fast for 16 hours and eat within an 8-hour window.
  • Alternate-day fasting (ADF)- This method involves alternating between a day of normal eating and a day of complete or partial fasting.
  • 5:2 diet- This method involves eating normally for five days a week and restricting calorie intake to 500-600 calories on the remaining two non-consecutive days.

IF has been shown to have several potential health benefits, including weight loss, improved blood sugar control, reduced inflammation, and increased longevity. However, it may not be suitable for everyone, particularly those with certain medical conditions or who are pregnant or breastfeeding.

It’s important to note that while IF may be an effective weight loss tool, it’s not a magic solution and still requires an overall calorie-deficit diet, healthy eating habits, and lifestyle choices.

Paleo Diet

The Paleo diet, also known as the Paleolithic or caveman diet, is based on the idea of eating foods that our ancient ancestors consumed during the Paleolithic era, which ended approximately 10,000 years ago.

The diet consists mainly of foods that could be hunted, fished, or gathered, such as meat, fish, fruits, vegetables, nuts, and seeds.

Paleo diet eliminates grains, legumes, dairy, and processed foods, as these foods were not commonly consumed during the Paleolithic era. The diet also emphasizes high-quality, unprocessed foods and encourages the use of healthy fats, such as those found in avocados, nuts, and olive oil.

This diet has been linked to a few potential health benefits, including weight loss, improved blood sugar control, reduced inflammation, and better digestion. However, some experts have raised concerns about the diet’s potential to be low in certain nutrients, such as calcium and vitamin D, due to the exclusion of dairy.

GM Diet

The GM diet, also known as the General Motors diet, is a seven-day diet plan that involves consuming specific foods each day. The diet plan is said to have been developed by General Motors in collaboration with the Food and Drug Administration (FDA) and the United States Department of Agriculture (USDA) for their employees to help them lose weight.

This diet plan involves consuming different food groups on each day, such as fruits on day one, vegetables on day two, and a mix of fruits, vegetables, and brown rice on day three. On day four, the plan allows for the consumption of bananas, milk, and soup, and on day five, it includes beef, tomatoes, and brown rice. The last two days involve the consumption of brown rice, vegetables, and fruit juice.

While the GM diet may lead to rapid weight loss, it has been criticized for being too restrictive and potentially lacking in important nutrients. The diet also promotes the consumption of certain foods, such as beef, which may not be suitable for vegetarians or vegans.

It’s important to note that the GM diet should not be followed long-term and may not be suitable for everyone, particularly those with certain medical conditions or who are pregnant or breastfeeding.

Keto Diet

The ketogenic diet, or keto diet, is a high-fat, low-carbohydrate diet that involves reducing carbohydrate intake and replacing it with fat. The diet aims to put the body into a metabolic state called ketosis, where it uses ketones from fat as its primary source of fuel instead of glucose from carbohydrates.

This diet typically involves consuming 75% of calories from fat, 20% from protein, and 5% from carbohydrates. This means limiting carbohydrate-rich foods such as grains, fruits, and starchy vegetables and increasing consumption of high-fat foods such as nuts, seeds, avocados, and fatty meats.

The keto diet may help with weight loss, improved blood sugar control, reduced inflammation, and decreased risk of certain chronic diseases. However, it can be challenging to follow and may be difficult to sustain long-term.

There are also potential side effects of the keto diet, such as nutrient deficiencies, constipation, and an increased risk of heart disease due to the high intake of saturated fat. It’s important to consult with a healthcare professional before starting the keto diet, particularly if you have a medical condition or are taking medication.

Mediterranean Diet

The Mediterranean diet is a dietary pattern based on the traditional eating habits of people living in countries bordering the Mediterranean Sea. It emphasizes the consumption of plant-based foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds, as well as seafood, poultry, and dairy in moderation. Red meat is consumed in small amounts, if at all.

The Mediterranean diet also emphasizes the use of healthy fats, such as olive oil, and limits the consumption of saturated and trans fats. The diet is high in antioxidants and fiber and is known for its anti-inflammatory properties.

Research has linked the Mediterranean diet to several potential health benefits, including reduced risk of heart disease, stroke, and certain types of cancer, as well as improved cognitive function and longevity. The diet has also been shown to be effective for weight loss and weight management.

This diet limits the consumption of dairy products which can cause a drop in the levels of certain nutrients, namely calcium and vitamin D.

The regular use of wine while following the Mediterranean diet has given rise to some major difficulties. Alcohol is an addictive substance, therefore even while moderate alcohol use may reduce cardiovascular risk, it might potentially be hazardous. Additionally, a study demonstrates that increased drinking is linked to a higher chance of death.

 Instead of examining the Mediterranean diet as a whole, you might examine each of its constituent parts. Include good fats in your diet, eat a lot of fiber vegetables, eat well-made meals, and stay away from items high in calories. These things individually and collectively improve your health.


There are many different dieting strategies available, and each has its own set of potential benefits and drawbacks. It’s important to find a diet that works for your individual needs and goals, as well as one that is sustainable for long-term health and well-being. Before starting any diet, it’s always a good idea to consult with a healthcare professional to ensure that the diet is safe and appropriate for you. Additionally, it becomes important to keep in mind that a healthy diet should be balanced and provide all the necessary nutrients, and that physical activity and lifestyle factors are also important for overall health and weight management.
