What Is A Vegan Diet?

A vegan diet means avoiding all animal products. That includes meat, poultry, fish, dairy, eggs, and even honey. From our experience, most people are surprised to learn that veganism goes beyond food. Many also avoid products like leather, wool, and certain cosmetics that involve animal exploitation.

At its core, a vegan diet focuses on plants: fruits, vegetables, legumes, whole grains, nuts, seeds, and plant-based fats.

What Is A Vegan Diet Plan?

A vegan diet plan is a structured approach to eating that ensures you're meeting your nutritional needs without animal products.

A well-designed vegan plan prioritizes variety. It leans on whole foods like beans, lentils, tofu, whole grains, nuts, seeds, and plenty of colorful fruits and vegetables.

It’s not just a matter of swapping chicken for tofu. A solid vegan meal plan balances protein, healthy fats, fiber-rich carbohydrates, and essential micronutrients like vitamin B12, iron, calcium, and omega-3s, which are nutrients that need a little extra attention when animal foods are off the table.

Why Do People Follow A Vegan Diet?

Some are motivated by ethics, choosing to avoid contributing to animal suffering. Others are drawn by environmental concerns, knowing that plant-based diets typically use fewer resources and generate less greenhouse gas emissions.

Then there are those seeking health benefits. Research shows that well-planned vegan diets are associated with lower risks of heart disease, type 2 diabetes, and certain cancers. Some clients come to us after hearing about the potential for better blood sugar control, weight management, or simply feeling more energized.

Types Of Vegan Diets

Whole-Food Vegan

This is the type we most often recommend at Berry Street. It emphasizes minimally processed foods like fruits, vegetables, legumes, whole grains, nuts, and seeds. It’s rich in fiber, antioxidants, and nutrients.

Junk-Food Vegan

Yes, you can technically eat fries, vegan ice cream, and plant-based burgers all day and still be vegan. But from our experience, this version lacks the nutrient density needed for long-term health.

Raw Vegan

This diet consists of raw fruits, vegetables, nuts, and seeds—foods not heated above 118°F. It can work, but it's more restrictive and takes careful planning to avoid nutrient gaps.

Low-Fat Raw Vegan (Fruitarian)

This version focuses primarily on fruit, sometimes with small amounts of greens and vegetables. In our experience, this is one of the most restrictive forms and often requires supplements to avoid deficiencies.

Plant-Based But Not Fully Vegan

Some folks follow a plant-forward diet, meaning most, but not all, of their foods come from plants. They may occasionally eat animal products but prioritize plants.

Benefits Of A Vegan Diet

Improved Heart Health

Heart health improvements are often one of the first noticeable changes on a vegan diet. Research shows that plant-based diets help reduce LDL (bad) cholesterol, lower blood pressure, and decrease the overall risk of heart disease.

This is largely thanks to the absence of saturated fats found in animal products and the increase in fiber-rich foods like legumes, whole grains, fruits, and vegetables.

Fiber helps clear cholesterol from the bloodstream, while antioxidants from plant foods reduce inflammation. And yes, we've seen clients drop their cholesterol numbers in as little as a few months.

Weight Management

Weight loss isn't magic. But when it happens sustainably, it’s life-changing. A well-planned vegan diet tends to be naturally lower in calories because plant-based foods are high in fiber and water content but low in calorie density.

Simply put, you can eat larger portions while consuming fewer calories, which is perfect for beginner weight loss meal prep. Clients report feeling satisfied, not deprived, while steadily losing weight. The bonus? Less processed food, more nutrients, and better digestion.

Better Blood Sugar Control

One of the most encouraging things we’ve witnessed in our practice is how a vegan diet can support blood sugar stability. Research indicates that vegetarians and vegans are significantly less likely to develop type 2 diabetes compared to meat-eaters.

High-fiber foods, like beans, lentils, oats, and veggies, slow down how quickly sugars enter the bloodstream. This means fewer spikes and crashes.

Clients living with prediabetes or type 2 diabetes often report improved blood glucose control, sometimes requiring fewer medications over time.

Lower Cancer Risk

A growing body of research links plant-based diets with a lower risk of certain types of cancer, including breast, prostate, and colorectal cancers. A big reason for this is the elimination of processed meats, which are carcinogenic.

Combine that with the abundance of antioxidants, phytochemicals, and fiber found in plants, and you get a diet that actively supports cellular repair and reduces inflammation. We've seen clients feel empowered knowing their food choices can play a role in long-term disease prevention.

Reduced Environmental Impact

A shift towards a vegan diet can have positive impacts on planetary health as well as personal health.

Animal agriculture uses vast amounts of water, land, and energy and contributes significantly to greenhouse gas emissions. Plant-based diets typically require fewer resources and result in a smaller carbon footprint.

That being said, if you are considering switching to a vegan diet, it’s crucial to ensure that you do so correctly. If you simply remove animal products from your diet without replacing them with healthy alternatives, you risk nutrient deficiencies.
