Plant-Based Diets – What You Need to Know


In recent years, plant-based diets have gained tremendous popularity, with more and more people embracing this way of eating for various reasons, including health and environmental considerations. This year, the flexitarian diet (also known as the semi-vegetarian diet) and several other plant-based diets made it to the top of the “Best Diets Overall,” “Best Weight-Loss Diets,” and “Best Diets for Healthy Eating” lists.

In this article, we explore plant-based diets and their health benefits, address misconceptions about these diets, examine the proven effects of plant-based diets in individuals with various lifestyles, and highlight the positive impact this lifestyle can have on overall well-being.

What is a plant-based diet?

A plant-based diet is centered around whole, unprocessed plant foods, such as fruits, vegetables, grains, legumes, nuts, and seeds. While some variations of plant-based diets may still include small amounts of animal products, the primary focus is on maximizing the consumption of nutrient-dense plant foods while minimizing the intake of animal-derived products.

Let’s look at some of the most popular plant-based diets:

Mediterranean Diet

The Mediterranean Diet consists primarily of plant-based foods, but also includes seafood and lean poultry. It originates in countries bordering the Mediterranean Sea, including Greece, Italy, and Turkey. If you would like to learn more about the Mediterranean diet, read our article here.

Flexitarian Diet

The Flexitarian Diet is a flexible and plant-focused eating pattern that allows occasional inclusion of animal-based products. It encourages consuming mostly plant-based foods while allowing for the occasional enjoyment of meat and other animal products in moderation.

The DASH (Dietary Approaches to Stop Hypertension) Diet is designed to prevent and manage high blood pressure. It emphasizes nutrient-rich foods, particularly fruits, vegetables, whole grains, and lean protein sources, while limiting sodium and unhealthy fats.

The MIND (Mediterranean-DASH Diet Intervention for Neurodegenerative Delay) Diet is a hybrid of the Mediterranean and DASH diets, specifically designed to support brain health and reduce the risk of neurodegenerative diseases, such as Alzheimer’s disease.

Vegetarian Diet

The Vegetarian Diet revolves around plant-based foods, omitting meat and seafood. Vegetarians still consume dairy and eggs. This diet emphasizes nutrient-rich plant foods as the foundation of a well-balanced and compassionate eating pattern.

Vegan Diet

The Vegan Diet takes plant-based eating to the next level by abstaining from all animal products, including meat, dairy, eggs, and even honey. This approach to nutrition is centered around whole plant foods, making it rich in vitamins, minerals, and antioxidants while excluding all animal-derived sources.

Health Benefits of Plant-Based Diets

The shift to a plant-based diet can offer numerous health advantages, backed by scientific research.

Reduced Risk of Chronic Diseases

Plant-based diets have been linked to a reduced risk of chronic conditions such as heart disease, Alzheimer’s, and type 2 diabetes. The abundance of antioxidants, fiber, and other beneficial compounds in plant foods contributes to improved health outcomes.

Lower Cholesterol Levels and Improved Heart Health

By avoiding or minimizing high-cholesterol animal products and incorporating heart-healthy plant foods, individuals on plant-based diets often experience lower cholesterol levels and a decreased risk of heart-related issues.

Weight Management and Support for Healthy Weight Loss

Plant-based diets, when balanced and properly planned, can be effective for weight management and support healthy weight loss. The focus on whole, nutrient-dense foods can lead to feeling more satisfied and less likely to overeat.

Enhanced Digestion and Gut Health

Plant-based diets are naturally high in fiber, which promotes healthy digestion and supports a diverse and thriving gut microbiome.

Increased Intake of Vitamins, Minerals, and Antioxidants

A variety of plant-based foods provides a wide range of essential vitamins, minerals, and powerful antioxidants, contributing to overall health and well-being.

Positive Effects on Blood Sugar Levels

Plant-based diets have been shown to improve blood sugar control, making them beneficial for individuals with or at risk of type 2 diabetes.

Busting Myths: Plants Don’t Provide Enough Protein

One common misconception about plant-based diets is that they might not provide sufficient protein. However, a well-balanced plant-based diet can easily meet protein needs through sources such as legumes (beans, lentils, chickpeas), tofu, tempeh, quinoa, nuts, and seeds. Additionally, plant-based diets can offer ample amounts of essential vitamins and minerals when appropriately planned, ensuring all nutritional needs are met. For essential omega-3 fatty acids, alternatives like flaxseeds, chia seeds, and walnuts can be included in the diet.

Plant-Based Diets for Different Lifestyles


Contrary to the belief that athletes require animal protein for optimal performance, studies have shown that plant-based diets can effectively provide all the necessary nutrients and energy for athletes. Many successful athletes have thrived on plant-based diets, debunking the myth that animal products are essential for athletic performance.

Families with Children

Plant-based diets have proven to be beneficial for both kids and adults, offering lower risks of heart disease, diabetes, and high blood pressure. With proper planning and attention to nutrient intake, plant-based diets can support the health and growth of children as they develop.

Busy Individuals

For those with hectic schedules, plant-based diets can be accommodated with convenient and quick meal options. Preparing smoothies, overnight oats, or salads ahead of time allows busy individuals to maintain their nutrient intake without sacrificing time or energy.

Advice for Transitioning to a Plant-Based Diet

Make a gradual transition to a plant-based diet

Instead of diving into a strict plant-based diet all at once, take it step by step. Start by incorporating more plant-based meals into your weekly routine while gradually reducing your consumption of animal-based products. This gradual approach allows your taste buds and body to adjust, making the transition more sustainable and enjoyable.

Experiment with new recipes and flavors

Embrace the diversity of plant-based foods by trying out new recipes and exploring a wide array of flavors and cuisines. There are countless plant-based dishes that are not only delicious but also packed with nutrients. Don’t be afraid to get creative and discover exciting plant-based alternatives to your favorite meals.

Seek support and resources

Joining plant-based communities and finding credible websites can be incredibly motivating and informative. Online platforms and social media groups can provide valuable resources, tips, and recipes to support your plant-based journey. Sharing experiences with others can also create a sense of community and encouragement.

Consult with a healthcare professional or registered dietitian

While plant-based diets can be nutritionally beneficial, it’s essential to ensure you are meeting all your nutrient needs. Consulting with a healthcare professional or registered dietitian can help you develop a well-balanced and individualized approach to your plant-based diet. They can provide personalized guidance, address any nutritional concerns, and tailor dietary recommendations to your specific health goals.

Summing It Up

Embracing a plant-based diet presents a wealth of health benefits, ranging from decreased risks of chronic illnesses to improved heart health, weight management, and better digestion. Mindful and informed dietary choices can significantly impact your overall well-being. Delve into the advantages of plant-based foods and other diet options to cultivate a balanced and nourishing lifestyle that supports your optimal health and vitality.

Lomaira™ (phentermine hydrochloride USP) 8 mg tablets, CIV is a prescription medicine used for a short period of time (a few weeks) for weight reduction and should be used together with regular exercise and a reduced-calorie diet. Lomaira is for adults with an initial BMI* of 30 or more (obese) or 27 or more (overweight) with at least one weight-related medical condition such as controlled high blood pressure, diabetes, or high cholesterol. The limited usefulness of this drug class (anorectics), including Lomaira, should be measured against possible risk factors inherent in their use.

Don’t take Lomaira™ if you have a history of cardiovascular disease (e.g., coronary artery disease, stroke, arrhythmias, congestive heart failure or uncontrolled high blood pressure); are taking or have taken a monoamine oxidase inhibitor drug (MAOI) within the past 14 days; have overactive thyroid, glaucoma (increased pressure in the eyes), agitation or a history of drug abuse; are pregnant, nursing, or allergic to the sympathomimetic amines such as phentermine or any of the ingredients in Lomaira.

Taking phentermine with other drugs for weight loss is not recommended. Primary pulmonary hypertension (PPH), a rare fatal lung disease, has been reported in patients who had taken a combination of phentermine and fenfluramine or dexfenfluramine for weight loss. The possible association between phentermine use alone and PPH cannot be ruled out. Patients should report immediately if they experience any decrease in the amount of exercise that they can normally tolerate, shortness of breath, chest or heart pain, fainting or swelling in the lower legs.

Serious heart valve problems or disease have been reported in patients taking a combination of phentermine and fenfluramine or dexfenfluramine for weight loss. The possible role of phentermine has not been established, therefore the possibility of an association between heart valve disease and the use of phentermine alone cannot be ruled out.

If your body becomes adjusted to the maximum dose of phentermine so that its effects are experienced less strongly, the maximum dose should not be exceeded in an attempt to increase the effect.

Caution is advised when engaging in potentially hazardous activity such as driving or operating machinery while taking phentermine. Phentermine has the potential to be abused. Keep Lomaira in a safe place to prevent theft, accidental overdose, misuse or abuse. Using alcohol with phentermine may result in an adverse drug reaction.

Phentermine can cause an increase in blood pressure. Tell your doctor if you have high blood pressure, even if it’s mild. If you are taking medicines for type 2 diabetes, your doctor may have to adjust these medicines while taking phentermine.

Some side effects of phentermine that have been reported include pulmonary hypertension, valvular heart disease, palpitations, increased heart rate or blood pressure, insomnia, restlessness, dry mouth, diarrhea, constipation and changes in sexual drive. These are not all of the potential side effects of phentermine. For more information, ask your doctor or pharmacist.

To report negative side effects of prescription drugs, contact FDA at 1-800-FDA-1088 or visit
