With the abundance of diet plan options, it can be overwhelming to know where to start. But, it’s important to remember that diets aren’t just for weight loss. In fact, a well-planned diet can be a key component in improving your habits, focusing on your health, and leading an active lifestyle.
When considering a diet, it’s crucial to find one that is sustainable and appropriate for your individual needs. Some diets emphasize limiting your food intake, while others focus on reducing your intake of specific macronutrients.
Additionally, some diets place a greater emphasis on changes in eating patterns and lifestyle, rather than restricting specific foods.
It’s also worth noting that many diets offer benefits beyond just weight loss. Here are nine of the best diet plans to consider for improving your overall health.
1. The Mediterranean diet plan
The Mediterranean diet is a dietary pattern inspired by the traditional foods and lifestyle practices of the countries surrounding the Mediterranean Sea.
How it works
The Mediterranean diet emphasises the consumption of whole, minimally processed foods, such as:
- Fruits and vegetables: such as tomatoes, olives, grapes, and oranges
- Nuts and seeds: such as almonds and pumpkin seeds
- Whole grains: such as whole wheat bread and brown rice
- Legumes: such as lentils and chickpeas
- Olive oil: as the primary source of added fat
- Fish and seafood: such as salmon and sardines
- Poultry and eggs: consumed in moderation
In the Mediterranean diet, it is recommended to limit or consume in moderation certain animal-based foods, including poultry, eggs, and dairy products. Red meats should also be limited in this diet.
Additionally, the Mediterranean diet restricts or limits the consumption of the following:
- Processed and high-fat meats such as bacon, sausages, and ham.
- Refined grains and sugars such as white bread and sugar-sweetened beverages.
- Trans fats and added sugars found in processed and packaged foods.
- Saturated fats found in butter, lard, and high-fat dairy products.
Health benefits
The Mediterranean diet has been linked to a number of health benefits, including:
Reduced risk of heart disease: This diet has been shown to lower the risk of heart disease and stroke by reducing inflammation, improving cholesterol levels, and lowering blood pressure.
Improved weight management: The Mediterranean diet, with its emphasis on whole, minimally processed foods, can lead to a reduction in calorie intake and improved weight management (Study).
A study of over 500 adults found that those who followed the Mediterranean diet more closely were twice as likely to successfully maintain weight loss over a period of 12 months (Study).
Lower risk of type 2 diabetes: This diet has been shown to improve insulin sensitivity and glycemic control, reducing the risk of developing type 2 diabetes.
Reduced risk of certain types of cancer: The consumption of fruits, vegetables, and whole grains in the Mediterranean diet has been linked to a lower risk of certain types of cancer (Study).
Better brain health: The Mediterranean diet has been associated with a reduced risk of age-related cognitive decline and a reduced risk of Alzheimer’s disease (Study).
Improved gut health: This diet is high in fiber, which can support the growth of healthy gut bacteria and improve gut health.
These health benefits have been attributed to the nutrient-rich and balanced nature of the Mediterranean diet, as well as the focus on lifestyle practices, such as physical activity and stress management, that are an integral part of this way of life.
Additionally, the Mediterranean diet promotes the consumption of foods high in antioxidants, which can fight inflammation and oxidative stress by neutralizing harmful free radicals (Study).
Downside
Because the Mediterranean diet doesn’t place a strong emphasis on dairy products, it’s crucial to ensure adequate intake of calcium and vitamin D through alternative sources.
Summary
The Mediterranean diet emphasizes a diet rich in fruits, vegetables, fish, and healthy oils and limits the consumption of refined and processed foods.
Although it is not a diet solely for weight loss, research indicates it can still lead to weight loss and improved overall health.
2. The DASH diet plan
The DASH (Dietary Approaches to Stop Hypertension) diet is a healthy eating plan designed to lower blood pressure and improve heart health.
It emphasizes a diet rich in fruits, vegetables, whole grains, low-fat dairy, lean protein, and healthy oils, while limiting salt, red meat, sugary drinks, and processed foods.
The DASH diet has been shown to be effective in reducing high blood pressure, reducing the risk of heart disease, and promoting weight loss.
Although the primary focus of the DASH diet is not weight loss, many people who follow the diet have reported losing weight.
How it works
The DASH diet provides specific serving recommendations for different food groups. The recommended daily servings include (Study) :
- Fruits: 4-5 servings
- Vegetables: 4-5 servings
- Whole grains: 6-8 servings
- Low-fat dairy: 2-3 servings
- Lean protein: 6 or fewer servings
- Nuts, seeds, and legumes: 2-3 servings per week
- Fats and oils: 2-3 servings
- Lean meat products: 1-2 servings
These serving recommendations are based on a 2,000 calorie diet, and can be adjusted based on individual calorie needs.
The DASH diet encourages eating a variety of nutrient-dense foods from each food group and limiting high-sodium foods and added sugars.
Health benefits
The DASH diet has numerous health benefits, including:
Study supporting DASH > (Study 1) (Study 2) (Study 3) (Study 4) (Study 5)
Lowering Blood Pressure: The DASH diet is designed to lower blood pressure by reducing salt intake and increasing potassium, magnesium, and calcium intake.
Reducing the Risk of Heart Disease: By following the DASH diet, you may reduce your risk of heart disease and stroke. The diet’s emphasis on fruits, vegetables, whole grains, and low-fat dairy, as well as its limits on salt, red meat, and added sugars, are all beneficial to heart health.
Supporting Weight Loss: While the DASH diet is not a weight loss diet, many people find they lose weight while following it, due to its focus on nutrient-dense, low-calorie foods and its limits on high-calorie, highly processed foods. 13 Studies have shown that people following the DASH diet tend to lose more weight compared to those on a control diet over a period of 8-24 weeks (Study).
Improved Digestive Health: The DASH diet’s focus on fiber-rich fruits, vegetables, and whole grains can help improve digestive health by promoting regularity and reducing the risk of digestive disorders.
Better Blood Sugar Control: By emphasizing whole grains, fruits, and vegetables and limiting added sugars, the DASH diet can help regulate blood sugar levels and reduce the risk of type 2 diabetes.
Improved Bone Health: The DASH diet is high in calcium, magnesium, and potassium, all of which are important for maintaining strong bones.
Overall, the DASH diet is a healthy, balanced eating plan that can improve heart health, support weight loss, and promote overall wellness (Study).
Downsides
It is not yet fully clear if a low sodium diet like the DASH diet is suitable for everyone, as it has been mainly studied for its effects in individuals with hypertension.
The DASH diet, which is low in sodium, is better suited for those who have hypertension or medical conditions that benefit from reducing their sodium intake (Study).
More research is needed to determine the impact of low sodium diets on insulin resistance in those without hypertension.
Summary
The DASH diet is a dietary pattern that emphasizes whole foods such as fruits, vegetables, whole grains, lean proteins, and low-fat dairy while limiting processed foods, added sugars, and saturated fats.
The purpose of the diet is to help improve heart health and lower the risk of chronic diseases. The DASH diet also limits salt intake, making it a low sodium diet, which is particularly beneficial for people with hypertension.
Some research has also shown that following the DASH diet may lead to weight loss, improved insulin resistance, and reduced risk of certain cancers.
3. Plant-based and flexitarian diet plans
Plant-based diets are popular for various reasons, including health, ethics, and environmental concerns, and they involve limiting or eliminating animal products. The two most well-known versions of plant-based diets are vegetarianism and veganism.
The plant-based diet is completely free of animal products, including meat, dairy, and eggs, while the flexitarian diet allows for the occasional inclusion of animal products.
The plant-based and flexitarian diets are both focused on reducing or eliminating animal products from the diet and emphasizing plant-based foods. This can include fruits, vegetables, whole grains, legumes, nuts, and seeds.
How it works
A vegetarian diet avoids meat but includes dairy, while a vegan diet abstains from all animal-derived products, including dairy and sometimes other byproducts like honey.
The flexitarian diet focuses on eating primarily plant-based foods such as fruits, vegetables, legumes, and whole grains while limiting processed foods and sugar.
However, it also permits the consumption of meat and animal products in moderation, making it a more flexible and adaptable approach to eating.
Health benefits
Eating a diet that primarily consists of fruits, vegetables, legumes, and whole grains has been linked to improved metabolic health, lower blood pressure, and a reduced risk of chronic diseases such as type 2 diabetes. Research has also shown that a plant-based diet can help with weight loss (study).
The flexitarian diet can also help reduce the risk of type 2 diabetes, improve your metabolic health, lower your blood pressure, and potentially promote weight loss (study).
Downsides
Adopting a plant-based eating style such as vegetarianism or veganism may present challenges, especially if it’s a major shift from your previous eating habits.
On the other hand, the flexible nature of a flexitarian diet may make it easier to follow, but if you’re too flexible with it, you may not receive its full benefits.
Summary
In another way, following a plant-based diet such as veganism or vegetarianism can lead to improved health outcomes such as decreased risk of chronic diseases, but it may also pose a challenge for those who are accustomed to a meat-based diet.
On the other hand, the flexibility of a flexitarian diet makes it a more manageable option for some, allowing for occasional meat and animal product consumption, but being too flexible with it may negatively impact its potential health benefits.
4. The MIND diet plan
The MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet is a hybrid of the Mediterranean diet and the DASH diet. It was developed specifically to boost brain health and slow down the progression of neurodegenerative diseases such as Alzheimer’s.
The MIND diet focuses on the consumption of foods that have been shown to improve cognitive function and reduce the risk of cognitive decline and dementia, such as leafy greens, berries, nuts, and legumes. It also restricts the intake of foods that have been linked to cognitive decline, such as fried and processed foods.
Research has shown that following the MIND diet can improve memory and cognitive function, reduce inflammation, and lower oxidative stress, which are all risk factors for cognitive decline and dementia.
The MIND diet emphasizes eating whole, nutrient-rich foods and limiting the intake of unhealthy, processed foods.
How it works
The MIND diet focuses on incorporating specific foods known to have brain health benefits. It is not a strict meal plan, but instead provides guidelines for eating certain foods regularly.
To follow the MIND diet, it is recommended weekly to eat:
- Six or more servings of green, leafy vegetables per week for their brain-protective benefits.
- At least one serving of non-starchy vegetables each week.
- Five or more servings of nuts per week, which are a rich source of healthy fats and antioxidants.
In addition to these staple foods, the MIND diet also suggests incorporating the following into your diet multiple times a week:
- Berries, which are high in antioxidants and have been linked to improved brain function.
- Beans, which are a good source of protein, fiber, and other nutrients important for brain health.
- Olive oil, which is high in healthy monounsaturated fats and has been shown to benefit brain function.
- Whole grains, which are a good source of fiber and essential nutrients.
- Fish, which is high in omega-3 fatty acids and has been linked to improved brain function.
- Poultry, which is a good source of lean protein and important nutrients for brain health.
By incorporating these foods into your diet, the MIND diet aims to support brain health and potentially reduce the risk of cognitive decline.
Health benefits
The MIND diet is designed to improve brain health and reduce the risk of developing Alzheimer’s disease. It is considered to be a more effective plant-based diet for improving cognition compared to others (Study).
Studies have shown that following the MIND diet can slow cognitive decline, increase resilience in older adults (study), and potentially delay the onset of Parkinson’s disease (study).
While there is limited research on the relationship between the MIND diet and weight loss, the diet may still contribute to weight management as it encourages limiting unhealthy foods, such as butter, cheese, red meat, fried foods, and sweets. Further research is needed to fully understand the impact of the MIND diet on weight loss.
Summary
The MIND diet is a combination of the Mediterranean and DASH diets and is believed to potentially lower the risk of Alzheimer’s disease and dementia. However, the extent of its ability to aid in weight loss has not been fully researched and requires further study.
5. WW (formerly Weight Watchers) diet plan
WW, previously known as Weight Watchers, is a well-known weight management program globally. It offers a flexible approach to dieting and doesn’t ban any specific food groups.
However, those on the program are encouraged to stay within their allotted daily points to achieve their target weight (Study).
How it works
WW is a weight loss program that operates on a point system. Participants are given a daily points allowance, based on their personal weight loss goals and individual factors such as height, age, and activity level. They can eat any food they choose, as long as they stay within their daily points limit.
The program also provides support through in-person meetings, an online community, and tracking tools to help people make healthy choices and develop sustainable habits for long-term weight loss success.
Additionally, WW offers a range of resources, including recipes, articles, and tools to help participants stay on track with their weight loss journey.
Health benefits
Some potential health benefits of following the WW program include:
Weight loss: By setting a daily point goal and tracking food intake, WW helps individuals monitor their food intake and make healthier choices, leading to weight loss (Study).
Improved nutrition: WW encourages members to eat a balanced diet that includes fruits, vegetables, whole grains, and lean protein, which can improve overall nutrition and reduce the risk of chronic diseases.
Increased physical activity: The WW program encourages physical activity, which can improve overall health and well-being, boost energy levels, and strengthen the immune system.
Better stress management: By helping individuals develop healthier habits and behaviors, WW can reduce stress and anxiety, leading to improved mental health.
Increased self-esteem: Achieving weight loss goals and improving overall health can lead to increased confidence and self-esteem.
Downsides
The cost of following WW, formerly Weight Watchers, can vary and be substantial, depending on the subscription plan and duration of participation.
While its flexible approach allows for a variety of food choices, it also puts responsibility on the dieter to make healthy choices.
Research has shown that significant weight loss and health benefits may not be realized until after a year of following the program (Study).
Summary
Weight Watchers, now known as WW, is a popular weight loss program that focuses on flexibility and moderation.
Participants must eat within a set number of daily points, but are not restricted from eating any specific food groups.
While the program may be costly, studies show that it can produce significant weight loss over a period of up to 52 weeks.
However, its flexibility can be a drawback if dieters make unhealthy food choices.
6. Intermittent fasting
Intermittent fasting is a type of diet that involves alternating periods of eating and fasting.
The most common forms of intermittent fasting include the 16/8 method, where you fast for 16 hours and eat within an 8-hour window, and the 5:2 diet, where you eat normally for five days and restrict calories to 500-600 for the remaining two.
Proponents of intermittent fasting claim it can lead to weight loss, improve insulin sensitivity, reduce oxidative stress and inflammation, and increase longevity.
However, more research is needed to establish its long-term effects and whether it’s appropriate for everyone. It’s important to speak with a healthcare provider before starting any new diet, especially if you have a medical condition.
How it works
Intermittent fasting is a weight loss technique that involves limiting the hours in which one is permitted to eat. By reducing the window of time for food consumption, one’s overall calorie intake is reduced, which can result in weight loss.
However, the effectiveness of this method depends on the individual’s ability to resist overeating during the designated meal periods.
Health benefits
The practice of intermittent fasting has been linked to a variety of positive outcomes, including anti-aging effects, enhanced insulin sensitivity, improved brain function, decreased inflammation, and other health advantages.
Studies, both in animals and humans, indicate that intermittent fasting could enhance heart health and prolong lifespan.
It has the potential to aid in weight loss.
Intermittent fasting has been found to stimulate the process of fat burning while preserving muscle mass, which can enhance metabolism.
Downsides
It’s important to note that certain individuals such as those with diabetes, low weight, an eating disorder, pregnant women, and breastfeeding mothers should consult with a healthcare professional before starting an intermittent fasting regimen due to its potential effects on blood sugar levels.
Summary
Intermittent fasting is a weight loss method that restricts the time frame for eating, leading to a reduction in calorie intake.
It has been linked to numerous health benefits including anti-aging effects, improved insulin sensitivity, and better heart health.
Studies also show that it can increase fat burning while preserving muscle mass, leading to an improved metabolism.
Although it is generally safe for most healthy adults, those with diabetes, low weight, eating disorders, pregnancy, or breastfeeding should consult with a health professional before starting.
7. Low carb diets
Low-carb diets restrict the consumption of carbohydrates, typically with the goal of promoting weight loss. By limiting carbohydrates, the body is forced to burn stored fat for energy instead of relying on glucose from carbohydrates.
The most popular low-carb diets include the Atkins diet, the ketogenic diet, and the South Beach diet.
How it works
Low-carb diets restrict the intake of carbohydrates, typically limiting them to around 20-150 grams per day, and increase the intake of protein and healthy fats.
This shift in macronutrient intake results in the body using stored fat for energy instead of relying on carbohydrates, which can lead to weight loss.
Additionally, low-carb diets can help regulate blood sugar levels, reduce inflammation, and improve heart health.
Health benefits
Low-carb diets have been linked to numerous health benefits, including:
Weight loss: Low-carb diets can be effective for weight loss, as they often lead to reduced calorie intake.
Improved insulin sensitivity: Low-carb diets have been shown to improve insulin sensitivity, which can help lower the risk of type 2 diabetes and other chronic diseases.
Better heart health: Low-carb diets have been linked to improved heart health, including lower blood pressure and cholesterol levels.
Better blood sugar control: By limiting carbohydrate intake, low-carb diets can help regulate blood sugar levels, which can be especially beneficial for people with type 2 diabetes.
Reduced inflammation: Low-carb diets have been shown to reduce inflammation in the body, which is linked to a number of chronic diseases.
It is important to note that the health benefits of low-carb diets may vary depending on the specific approach and individual factors such as age, gender, and health status.
Downsides
Low-carb diets have several potential downsides to consider. Some of these include:
Limited food choices: By restricting carbohydrates, many healthy foods like fruits, grains, and starchy vegetables are eliminated from your diet, which can lead to nutritional deficiencies.
Increased cholesterol levels: For some people, low-carb diets can cause an increase in cholesterol levels, particularly if they consume a lot of animal products.
Risk of nutrient deficiencies: Without carbohydrates, it can be difficult to consume adequate fiber, vitamins, and minerals, which can lead to nutrient deficiencies.
Changes in bowel movements: Reducing carbohydrates can lead to changes in bowel movements and digestive symptoms, including constipation.
High fat intake: Low-carb diets often require high fat intake to provide energy, which can lead to weight gain if not properly managed.
It is important to speak with a healthcare provider before starting any low-carb diet, especially for people with a history of heart disease, kidney problems, or liver disease.
Summary
Low carbohydrate diets limit carbohydrate consumption, promoting the use of fat as a source of energy.
These diets have been shown to promote weight loss and offer various health benefits.
The Bottom Line
There are many diets that can assist in weight loss and provide specific health benefits. Some popular examples include the Mediterranean diet, the MIND diet, WW (formerly Weight Watchers), the DASH diet, intermittent fasting, low carb diets, and plant-based diets.
The most appropriate diet for you should be based on your personal preferences and lifestyle, making it easier to maintain in the long run.
Before beginning a new diet, it is always recommended to consult with a doctor and consider the assistance of a registered dietitian to make meal planning more enjoyable.
