Why do diets work differently for each of us? Let’s explore the impact of diets on our health by weighing the pros and cons of five popular approaches.
Many of us have found ourselves scrolling through the internet, searching for information on various types of diets. Perhaps a friend or acquaintance has raved about the effectiveness of a particular diet for them.
Have you ever wondered why certain diets work for some people but not for others? Our health is paramount, and what we eat plays a significant role in determining our well-being.
Before embarking on a one-month diet challenge or any new eating regimen, let’s examine the advantages and disadvantages of five different diets.

Ketogenic diet
The ketogenic diet, often referred to as the keto diet, has gained immense popularity through social media, gym culture, and health magazines.
Mayo Clinic defines “keto” as short for “ketogenic,” a process in which the body uses fat as its primary fuel source instead of carbohydrates.
This diet primarily derives calories from dietary fats like butter, oil, nuts, and moderate amounts of protein-rich foods such as meat, full-fat cheese, fish, and eggs.
Initially used to reduce seizures in pediatric epilepsy patients, the keto diet is now promoted as a weight loss tool, as per Northwestern Medicine.
Advocates suggest that the diet leads to weight loss due to reduced hunger, as fatty foods take longer to digest.
Additionally, the diet allows people to enjoy high-fat foods like red meats, fatty fish, nuts, cheese, and butter while still losing weight.
However, sustaining the keto diet can be challenging due to its strict food restrictions. Many find it hard to adhere to, leading to a cycle of weight loss and regain, known as yo-yo dieting.
Achieving and maintaining ketosis, the metabolic state where the body burns fat for fuel, requires consistent food tracking and is verified through blood tests.
Furthermore, the diet’s limitations can result in nutrient deficiencies and feelings of fatigue and fogginess, commonly referred to as the “keto flu.”
Dehydration is also a common side effect due to the removal of glycogen, which retains water in the bloodstream.
This cycle of restriction and bingeing can perpetuate unhealthy eating habits and disrupt the body’s natural hunger cues.
While the ketogenic diet may offer short-term weight loss benefits, its long-term sustainability and potential health risks should be carefully considered before starting.
Vegan diet
Every January, many people participate in Veganuary, a month dedicated to embracing a vegan lifestyle.
Veganism involves avoiding all animal products, including meat, milk, eggs, and honey.
One benefit of a vegan diet is a reduced risk of certain illnesses, such as diabetes, hypertension, and heart disease, according to Healthy Living Direct.
Another advantage of veganism is its potential for weight loss. The diet’s focus on plant-based foods, which are lower in saturated fats and calories compared to animal products, can lead to weight loss for many new vegans.
Moreover, veganism promotes animal welfare by eliminating the need for animals to be harmed or killed for food.
This aspect often resonates with animal lovers, leading them to adopt a plant-based diet or reduce their meat consumption.
However, vegan diets can also have drawbacks. They may lack essential nutrients such as calcium, vitamin B12, and omega-3 fatty acids, which are primarily found in animal products.
Supplementation of these nutrients may be necessary, which can be costly.
Additionally, vegan diets may not be suitable for individuals with certain health conditions.
Conditions like osteoporosis, which require adequate calcium intake for bone strength, may necessitate the consumption of dairy products, a key source of calcium.
Another challenge of veganism is the limited options when eating out at restaurants or attending events.
While vegan options have become more prevalent, many establishments still offer a limited selection, and some may not offer any vegan-friendly meals at all.
While a vegan diet offers several health and ethical benefits, it’s important to consider the potential challenges and ensure that your diet is well-balanced and meets your nutritional needs.
Pescatarian diet
The pescatarian diet, or pescatarianism, combines a vegetarian diet with the inclusion of fish and other seafood. As per Medical News Today, this dietary choice can offer several health benefits.
One significant advantage is heart health. Fish, especially fatty varieties like salmon, herring, and trout, are rich in omega-3 fatty acids, which play a crucial role in regulating inflammation in the body.
Regular consumption of fish has been linked to a reduced risk of heart attacks, high blood pressure, atherosclerosis, and stroke.
Additionally, a diet high in vegetables and other plant foods, typical of the pescatarian diet, has been associated with a lower risk of coronary heart disease.
Another benefit is protection against colorectal cancer. Studies have shown that the pescatarian diet has a strong protective effect against colorectal cancers, which are a significant cause of cancer deaths.
However, there are some disadvantages to consider. Marine fish can contain heavy metals and pollutants, such as mercury, which is present in nearly all fish to some extent.
While most fish contain very low levels of mercury and are safe for consumption, certain fish, especially large predatory fish, can accumulate higher levels of mercury.
Pregnant women, nursing mothers, young children, and those considering pregnancy are advised to avoid these high-mercury fish.
The pescatarian diet offers numerous health benefits, but it’s important to be aware of potential risks associated with consuming certain types of fish.
Mediterranean diet
If you’re in search of a scientifically supported diet, the Mediterranean diet is a standout choice. Not only is it nutritious, but it also emphasizes flavorful meals over strict limitations.
This dietary pattern is prevalent in countries around the Mediterranean Sea. As reported by Very Well Fit, it has been associated with a reduced risk of various chronic diseases. This includes heart disease, cancer, and diabetes.
The Mediterranean diet is known for its delicious and varied flavors, making it a balanced and enjoyable way to eat. It has been linked to a lower risk of heart disease and can help prevent and manage diabetes.
Additionally, this diet may benefit mental health, aid in weight management, and reduce inflammation in the body.
Some studies even suggest that it may help prevent cancer. Moreover, the Mediterranean diet is sustainable and environmentally friendly.
However, there are some drawbacks to consider. Certain foods in the Mediterranean diet can be expensive, and individuals with specific health conditions may require additional guidance.
Some people may find certain dietary restrictions challenging to follow. Additionally, the diet may lack certain nutrients, and its lack of strict guidelines may be challenging for some. Preparation of Mediterranean meals may also require more time.
The Mediterranean diet offers numerous health benefits and is a flavorful and balanced approach to eating. However, it’s important to be aware of its potential challenges and limitations.
Intermittent fasting
Intermittent fasting is an eating pattern where you alternate between eating and fasting for a set period.
According to Mass General Brigham, one of the big advantages of intermittent fasting is its simplicity. You don’t need to track meals or count calories; it can easily fit into your daily routine.
Research suggests that intermittent fasting can offer several health benefits. This includes weight loss, lower cholesterol, and reduced blood pressure. As well as improved blood sugar levels, less inflammation, and better brain health. It also includes fewer age-related diseases, and possibly even a longer life.
However, most of the research has been conducted on animals. It’s not certain if humans would experience the same benefits.
Additionally, fasting may not be suitable for everyone. Especially those over 65 and individuals who are still growing. As well as people with diabetes, heart, kidney, or liver disease, or those who are pregnant or breastfeeding.
As reported by Health, new research has suggested a potential link between intermittent fasting and risk of cardiovascular disease-related death.
However, these findings are not yet published in a peer-reviewed journal and have been met with skepticism from medical professionals.
It’s crucial to interpret these findings cautiously. More research is needed to understand the long-term effects of intermittent fasting on health.
Finding Balance
Before you begin a new diet, it’s wise to consult with a doctor to determine the best approach for your health.
Remember, you can enjoy a variety of foods in moderation. The important thing is to find a balance that allows you to enjoy in your favorite foods without going overboard.
By finding this balance, you can maintain a healthy diet that works for you.
