Dieting: How Many People Actually Follow One?

how many people follow a diet

Many people follow a diet for a variety of reasons, including weight loss, health reasons, and religious or cultural beliefs. According to the CDC, approximately 17% of US adults aged 20 and over reported being on a special diet in 2015-2018, with more women adhering to a special diet than men. The most common reasons for following a special diet include weight loss, managing health conditions such as diabetes, celiac disease, or cardiovascular disease, and adhering to religious or cultural beliefs, such as vegetarianism or veganism. The popularity of different diets varies over time, and it is challenging to determine which diets are easier for people to follow or maintain. Factors influencing dietary patterns include income, food prices, individual preferences, cultural traditions, and geographical considerations.

Diet influenced by health, religion, culture, and beliefs

Dieting is a common practice, with approximately 17% of US adults reporting being on a special diet in 2015–2018, with more women (19%) than men (15.1%) adhering to a specific eating pattern. The reasons for following a diet vary, and can be influenced by health, religion, culture, and personal beliefs.

Health is a significant factor in influencing dietary choices. Many people adopt special diets to prevent, treat, or manage various health conditions, such as diabetes, celiac disease, or cardiovascular disease. For example, individuals with diabetes need to monitor their sugar and carbohydrate intake, while those with celiac disease must avoid gluten. Additionally, religious beliefs and practices can also shape dietary habits. Studies have shown that religious attendance and non-Christian affiliations are associated with higher health-conscious dietary patterns, increased micronutrient intake, and adherence to recommended guidelines.

However, the impact of religion on dietary habits is complex and varies across different faiths. For instance, fundamentalist religions often emphasize abstinence from tobacco and alcohol but may place less emphasis on moderation in food consumption, potentially leading to higher BMIs among adherents. Cultural traditions and norms also play a crucial role in shaping diets. Food choices are laden with personal, social, and cultural meanings that define our values, beliefs, and customs. Traditional food practices, methods of preparation, and seasonings vary across cultural groups, contributing to the diverse nature of dietary patterns worldwide.

Furthermore, individual beliefs and values can influence dietary decisions. Some people may choose to follow a vegan or vegetarian diet due to ethical concerns about animal welfare or the perceived unhealthiness of animal products. Others may be drawn to popular culture diets, such as the Paleo or Keto diets, in pursuit of weight loss or improved overall fitness and well-being. In conclusion, while health considerations play a pivotal role in shaping dietary choices, it is evident that religion, culture, and personal beliefs also exert a significant influence on the dietary patterns adopted by individuals.

Weight loss diets

A global study carried out across 30 countries found that 45% of people are trying to lose weight. This figure varies across countries, with 60% of people in Chile, over 50% in Spain, Peru, Saudi Arabia, Singapore, and the USA, and 40% in Japan and Hong Kong. In the US, nearly three-fourths of people are overweight or obese, and more than 160 million Americans are on a diet at any given time.

There are many different diets that people follow to lose weight. Some diets aim to curb your appetite to reduce your food intake, while others suggest restricting your intake of calories, carbs, or fat. Some focus more on certain eating patterns and lifestyle changes, rather than on limiting certain foods. The biggest challenge is finding the one that will work for you. The best diet is one that you will stick to, so it's important to find an approach that works for you specifically and keeps you motivated. It's also important to take your time, as sustainable weight loss happens slowly but steadily.

The Mediterranean diet is one popular option for weight loss. It emphasizes eating plenty of fruits, vegetables, legumes, nuts, whole grains, yogurt, cheese, poultry, and fish. Olive oil is used as the primary cooking fat, while red meat and foods with added sugars are eaten sparingly. Studies have shown that the Mediterranean diet is effective for weight loss and can also lower the risk of heart disease, diabetes, depression, and some forms of cancer.

Another diet that can aid in weight loss is the DASH diet (Dietary Approaches to Stop Hypertension). This diet was originally designed to help lower blood pressure and reduce the risk of heart failure, but it has also been shown to aid in weight loss. The DASH diet emphasizes eating plenty of fruits, vegetables, whole grains, and lean meats while restricting salt, red meat, added sugars, and fat.

In addition to following a specific diet, some people may also choose to simply reduce or eliminate certain components from their diet to help with weight loss. Sugar is the main factor that people look to reduce or eliminate, followed by calories, carbohydrates, processed foods, and saturated fats.

Fad diets

Some of the most famous fad diets include the Atkins diet, the ketogenic (or keto) diet, the Zone diet, the paleo diet, the Mediterranean diet, the vegetarian diet, intermittent fasting, and the detox diet. Atkins is all about low-carb eating, with stricter carb goals producing faster weight loss. The keto diet works by lowering insulin levels and shifting the body's primary fuel source from sugar to ketones, with a very low intake of carbs to ensure followers stay in ketosis. The paleo diet is based on the diets of hunter-gatherers from thousands of years ago and restricts many foods, including dairy, legumes, and grains. The Zone diet is based on the premise that a strict ratio of protein, fat, and carbs is required for optimal weight loss and overall health.

According to data from the National Health and Nutrition Examination Surveys (NHANES) for the years 2015-2018, approximately 17% of US adults aged 20 and over reported being on any type of special diet, with more women (19%) reporting being on a special diet than men (15.1%).

Healthy diet principles

While it is challenging to determine the exact number of people adhering to a specific diet, surveys and studies provide valuable insights into dietary trends. According to data from the National Health and Nutrition Examination Surveys (NHANES) in the United States, approximately 17.1% of adults aged 20 and over reported being on a special diet between 2015 and 2018. This percentage varied across different age groups, with younger adults aged 20-39 reporting lower rates of dieting compared to older adults.

Special diets are often adopted for weight loss or to address specific health concerns. Popular weight-loss diets include well-known programmes like Weight Watchers and cultural trends like the Paleo or Keto diets. Additionally, many individuals follow special diets due to health issues such as diabetes, celiac disease, or cardiovascular disease. Religious, ethical, and cultural beliefs also influence dietary choices, as seen in vegan and vegetarian diets.

Regardless of individual motivations, certain principles underpin a healthy diet. Here are some key principles to consider:

  • Plant-based Focus: A healthy diet should be abundant in plant foods, including vegetables, fruits, legumes, whole grains, nuts, and seeds. These foods offer a wide range of vitamins, minerals, fibre, and beneficial phytochemicals. They tend to be high in nutrients and relatively low in calories, making them ideal for both health and weight management.
  • Minimally Processed Foods: Ultra-processed foods are associated with adverse health outcomes. A healthy diet prioritises whole or minimally processed foods like broccoli, apples, almonds, plain yoghurt, canned tuna, and natural peanut butter. Processing often removes nutrients while adding unhealthy amounts of fats, sugars, and sodium.
  • Balanced Carbohydrates, Fats, and Proteins: While everyone requires carbohydrates, fats, and proteins, there is no magic ratio to strive for. The key is to avoid extremes and focus on quality. For example, some carbohydrates, like vegetables (excluding potatoes), fruits, whole grains, and beans, are healthier choices.
  • Healthy Culinary Practices: The way food is prepared also matters. The Spanish Society for Community Nutrition (SENC) recommends cooking techniques such as steaming, grilling, and oven cooking to reduce AGE/ALE content in food.
  • Hydration: Proper hydration is essential for a healthy diet. Water is the primary recommendation, but coffee and tea without added sugar are also suggested due to their potential health-promoting properties.
  • Avoid Alcohol: Alcohol has no safe level of consumption and, therefore, should not be included in a healthy diet.

Special diets

Many people follow special diets for a variety of reasons, including weight loss, health issues, religious or cultural reasons, or to improve their overall fitness and well-being. According to the CDC, approximately 17% of US adults aged 20 and over reported being on any type of special diet in 2015-2018, with more women (19%) adhering to a special diet than men (15.1%).

One common type of special diet is a weight loss or low-calorie diet. These diets can vary widely and may include popular culture diets such as the Paleo or Keto diets, or clinic- or company-formulated diets like Weight Watchers. Many people also follow diets to manage specific health issues. For example, those with diabetes need to monitor their sugar and carbohydrate intake, while those with heart disease are often advised to follow a low-fat, low-cholesterol, and low-carbohydrate diet. A renal diet is another example of a special diet that is carefully planned to address the specific needs of individuals with kidney disease.

In addition to these specific types of special diets, there are also more general categories of special diets that people may follow for health reasons. These include low-fat or low-cholesterol diets, low-salt or low-sodium diets, sugar-free or low-sugar diets, high-fiber diets, and high-protein diets.
