A healthy diet is important at any age, but the type of diet you follow may vary depending on your age. The earlier you start eating healthily, the better, as it can lead to a greater increase in life expectancy. However, making small changes to your diet at any age can still lead to major benefits and reduced mortality. In the US, the percentage of adults on any type of special diet increased from 14.3% in 2007-2008 to 17.4% in 2017-2018. The most common type of special diet among all adults was a weight-loss or low-calorie diet, with more women on a special diet than men, and more adults aged 40 and above on a special diet than younger adults.

What You'll Learn
Women diet more than men
Dieting is a common practice among people of all ages, but there are some notable differences between men and women when it comes to their dietary habits and preferences. According to various studies, women tend to diet more than men, and this tendency can be influenced by a variety of factors, including biological, cultural, and societal norms.
One of the key factors contributing to the higher prevalence of dieting among women is their body image and weight concerns. Women often experience greater dissatisfaction with their body weight and shape compared to men, which can lead them to engage in dieting behaviours to try and achieve a certain body ideal. This is supported by a twin study, which found that an earlier self-reported age at dieting onset is associated with a greater BMI, with girls who were already considered overweight at age five exhibiting higher levels of body dissatisfaction by age nine. Furthermore, women are more likely to have lower body satisfaction, regardless of their weight status, which can also motivate them to diet.
The social and cultural pressures to be thin, particularly in early adolescence, also play a significant role in influencing women's dieting behaviours. Women often experience more food-related conflict, as they like fattening foods but feel they shouldn't eat them due to societal expectations and pressures to maintain a thin figure. This conflict is less prevalent in men, who tend to prioritize taste and enjoyment when it comes to food choices. Men are also more likely to skip meals, especially breakfast, indicating a more relaxed and uncomplicated attitude towards food.
In addition to these factors, biological differences also contribute to the disparity in dieting behaviours between men and women. Women generally exhibit healthier eating habits, preferring plant-based foods, vegetables, whole grains, and tofu. They also tend to eat more regularly and report higher levels of hunger in the morning. On the other hand, men consume more calories and are more likely to prefer red and processed meat. These biological differences, influenced by genetics and hormonal responses, contribute to the gender discrepancy in dieting practices.
While dieting is more prevalent among women, it is important to note that it is not always effective for long-term weight loss maintenance. In fact, many dieters tend to regain the weight they lost or even gain more over time. This highlights the complex nature of dieting and the interplay of various factors that influence dietary choices and outcomes.

Older adults have the highest diet quality
Dieting is a common practice among people of all ages, with various motivations such as weight loss or health improvement. While dieting can be a way to promote weight loss, it has been found that dieting is not always successful for long-term weight loss maintenance, and some dieters even regain more weight over time.
When it comes to age, studies have shown that the prevalence of dieting increases with age, with more adults aged 40 and above following special diets compared to younger adults. This could be attributed to a variety of factors, including health concerns, weight-related issues, or even medical advice.
Among older adults, diet quality is of utmost importance. Adequate nutrition is crucial for healthy ageing, and a healthy diet can significantly reduce the risk of developing limitations in activities of daily living and depression. Older adults with healthier diets have a lower risk of chronic health conditions, which is especially important considering that 80% of older adults have at least one chronic health issue.
Several studies have examined the dietary patterns and their impact on healthy ageing. It has been found that higher intakes of fruits, vegetables, whole grains, unsaturated fats, nuts, legumes, and low-fat dairy products are linked to enhanced healthy ageing. On the other hand, higher consumption of trans fats, sodium, sugary beverages, and red or processed meats is negatively associated with healthy ageing. These dietary patterns, rich in plant-based foods and moderate amounts of healthy animal-based foods, can guide future dietary guidelines for older adults.
Additionally, social factors play a role in diet quality among older adults. Social isolation and loneliness can create challenges in accessing and preparing nutritious food, leading to unhealthy eating habits. Income and education levels also influence diet quality, with lower-income and less-educated individuals facing barriers in accessing good nutrition. Government policies and food assistance programs can help address these disparities and promote better nutrition among older adults, especially those with depression, disabilities, or those living alone.

Early dieting is linked to higher BMI
While there are no specific statistics on the age groups that diet the most, the percentage of U.S. adults on any type of special diet increased from 14.3% in 2007–2008 to 17.4% in 2017–2018. The most common type of special diet reported among all adults was a weight-loss or low-calorie diet.
Several studies have found a link between early dieting and a higher BMI in adulthood. A twin study of female twins aged 18–60 years found that an earlier age of dieting onset was associated with a greater adult BMI, higher Restraint Scale scores, greater use of risky dieting behaviours, and more weight cycling episodes. Another study found that girls who were considered overweight at age five had higher levels of disinhibited eating, dietary restraint, overweight concern, and body dissatisfaction by age nine.
The impact of early dieting on weight gain is not yet fully understood, and it may be influenced by genetic and familial factors. Some studies suggest that those who start dieting at an early age may be genetically predisposed to a higher BMI. Additionally, underlying genetic and familial factors may influence the association between early dieting and higher adult BMIs, particularly in women.
The relationship between early dieting and higher BMI has important implications for weight management and health. A higher BMI is associated with an increased risk of developing diabetes, heart disease, and cancer, as well as early death. Therefore, understanding the factors that contribute to weight gain and the development of unhealthy eating habits is crucial for promoting long-term health.

Weight loss diets are the most common
The percentage of U.S. adults on any type of special diet increased from 14.3% in 2007-2008 to 17.4% in 2017-2018. During this period, the percentage of adults on a weight loss or low-calorie diet increased from 7.5% to 10.0%. This indicates that more people are turning to dieting as a way to promote weight loss.
There are several popular weight loss diets, each with its own unique approach. Some common examples include intermittent fasting, the Atkins diet, the Mediterranean diet, and low-carb diets. Intermittent fasting involves restricting your daily eating period to a certain number of hours, typically 8 hours, and fasting for the remaining hours of the day. The Atkins diet is a well-known low-carb weight loss diet that allows for unlimited protein and fat intake while severely limiting carb consumption. The Mediterranean diet emphasizes the consumption of healthy fats, such as olive oil, along with fruits, vegetables, legumes, whole grains, and limited meat and dairy. Low-carb diets, as the name suggests, involve limiting carb intake to a minimum and using fats as the primary source of energy.
While weight loss diets are prevalent, it is important to note that dieting has not been proven to be successful for long-term weight loss maintenance. In fact, some studies suggest that most dieters tend to regain the weight they lost, or even gain more weight over time. Additionally, certain extreme diets that promote rapid weight loss can be dangerous and should only be done under medical supervision.

Healthier diets lead to longer lives
While there is no specific information on the age group that uses diets the most, it is evident that dieting is more prevalent among women and adults aged 40 and above. Additionally, obesity rates have increased globally, leading to a rise in dieting as a means of weight loss. However, it is worth noting that dieting has not proven effective for long-term weight loss maintenance, and some dieting methods can be risky.
Adopting healthier dietary habits can significantly impact an individual's longevity and overall health. Research suggests that a sustained shift towards healthier diets can increase life expectancy by up to 10 years. This is supported by studies indicating that a switch from a typical Western diet to an optimal diet from as early as age 20 can result in a notable increase in life expectancy, with greater gains for men.
The type of diet also matters. Vegetarian and vegan diets, which are rich in plant foods, are associated with a 12-15% lower risk of premature death. These diets have also been linked to a 29-52% reduced risk of dying from cancer, heart, kidney, or hormone-related diseases. Additionally, a diet high in fiber and fermented foods can help prevent inflammatory diseases.
The UK's Eatwell Guide dietary recommendations provide a framework for healthier eating. This includes increasing the consumption of whole grains, legumes, nuts, and fruits, while reducing sugar-sweetened beverages and processed meats. The Mediterranean diet, which emphasizes unprocessed foods, plant-based proteins, and unsaturated oils like extra-virgin olive oil, is another example of a longevity-associated diet.
It is important to note that dietary changes are most effective when combined with a physically active lifestyle. Additionally, other healthy habits such as adequate sleep, stress reduction, and limiting alcohol intake can further contribute to a longer and healthier life.
