Vegan Diet Benefits: How Soon Can You Expect Results?

A vegan diet can bring about a range of health benefits, but how long does it take to feel them? The answer depends on the benefit in question. Some changes will be immediate, such as the effect of fibre on digestive health. You may also notice increased energy levels within the first few weeks. Other benefits, like weight loss, can take a few weeks or even months. Lower blood pressure and cholesterol can take up to 10 days, while a reduced risk of type 2 diabetes may take several months. A lower risk of heart disease can take years.

Increased energy

A plant-based diet is a great way to enhance your energy levels. This is because plant-based foods are easier to digest, and certain plant-based foods contain energizing properties.

Animal foods are extremely hard to digest, and when the digestive system is overwhelmed, it can leave you feeling tired and sluggish. However, when you switch to a plant-based diet, your body will have the nutrients it needs to fuel you properly, giving you lasting energy.

You may notice an increase in your energy levels within a few weeks of adopting a plant-based diet. Some people report feeling more energized and less reliant on caffeine after just three to four weeks of eating plant-based foods.

It's important to note that a plant-based diet should be comprised of whole foods such as fruits, vegetables, whole grains, legumes, nuts, seeds, and leafy greens. A diet of processed vegan food, such as vegan cheesecake, veggie burgers, and french fries, is unlikely to provide the same energy-boosting benefits.

In addition to increased energy, a plant-based diet has been shown to improve digestion, mood, sleep, and heart health. It can also help with weight loss and reduce inflammation in the body.

Improved skin health

A vegan diet can bring about a noticeable improvement in skin health. The benefits of a vegan diet for the skin include a clearer complexion, a reduction in acne, and a more youthful appearance.

Clearer Skin

A vegan diet can lead to clearer skin due to the elimination of pro-inflammatory foods, particularly dairy, which is often a contributing factor to acne. By cutting out dairy, you can reduce skin irritation and promote a clearer, healthier complexion.

Reduction in Acne

The zinc found in beans, a common vegan protein source, has been found to combat acne and decrease skin inflammation. Additionally, healthy unsaturated fats found in avocados and olive oil provide fatty acids that keep the skin hydrated and supple.

More Youthful Appearance

Vitamins C and E, commonly found in vegan meals, are powerful antioxidants that neutralize skin-damaging free radicals. These vitamins help to fight wrinkles and brown spots, promoting a youthful appearance. The fiber from produce and whole grains also contributes to healthy, glowing skin by flushing out toxins.

While there is no definitive timeline, some people have reported seeing improvements in their skin within a few weeks to a month of adopting a vegan diet. However, it is important to note that results may vary, and individual factors such as skin type, overall health, and other lifestyle choices can influence the timeline for seeing improvements.

Improved gut health

Adopting a vegan diet can have a positive impact on gut health. Research has shown that a vegan diet can improve gut health in as little as a few days, with the benefits increasing over time. Here are some ways in which a vegan diet can improve gut health:

Increased Gut Microbiome Diversity

A vegan diet can increase the diversity of the gut microbiome, which is associated with improved gut health. A diverse gut microbiome is a healthy microbiome. A study by Zimmer et al. found that vegans had a significantly greater diversity of gut microbes compared to omnivores, specifically for certain Bacteroidetes-related operational taxonomic units (OTUs). These OTUs are considered protective against chronic inflammation and degenerative diseases.

Improved Bacteroidetes to Firmicutes Ratio

The ratio of Bacteroidetes to Firmicutes in the gut is an indicator of gut health. Bacteroidetes are beneficial bacteria that provide nutrients to the host and other intestinal microbes, while Firmicutes have a negative impact on glucose and fat metabolism. A vegan diet has been shown to increase the abundance of Bacteroidetes and decrease the abundance of Firmicutes, leading to a healthier ratio.

Reduced Pathobionts

Pathobionts are bacteria that can be harmful to the host under certain conditions. A study by Kim et al. found that a vegan diet reduced the abundance of pathobionts such as Enterobacteriaceae, which are associated with low-grade inflammation. This reduction in pathobionts may contribute to the anti-inflammatory effects of a vegan diet.

Increased Prebiotic and Probiotic Intake

A vegan diet is typically high in prebiotics, which are types of fiber that nourish beneficial gut microbes. Plant-based foods such as oats, barley, and some fruits are rich in prebiotics and can increase the abundance of beneficial bacteria while reducing the abundance of harmful bacteria. Additionally, a vegan diet can also be a good source of probiotics, which are live microorganisms that provide health benefits. Fermented vegan foods such as sauerkraut, miso, kimchi, and tempeh are excellent sources of probiotics.

Improved Blood Sugar Control

A vegan diet can help improve blood sugar control, which is beneficial for gut health. High blood sugar can lead to gut dysbiosis and an imbalance in the gut microbiome. A vegan diet is typically high in fiber, which helps regulate blood sugar and supports the growth of beneficial gut bacteria.

Reduced Risk of Gut-Related Diseases

A vegan diet has been linked to a reduced risk of gut-related diseases such as inflammatory bowel disease, irritable bowel syndrome, and colorectal cancer. The anti-inflammatory effects of a vegan diet may contribute to a lower risk of these diseases.

Lower blood pressure

High blood pressure, or hypertension, is a dangerous condition that affects one in four men and one in five women globally. It puts people at a greater risk of developing and dying from diseases of the heart, kidney, and brain. A plant-based diet can help lower blood pressure and reduce the risk of these diseases.

The Benefits of a Plant-Based Diet

According to research, a plant-based diet can help lower blood pressure and reduce the risk of hypertension. This is because plant-based diets are typically rich in vegetables, fruits, whole grains, nuts, and seeds, which contain various micronutrients that are beneficial for heart health.

Types of Plant-Based Diets

There are several types of plant-based diets that have been studied for their effects on blood pressure:

• The DASH (Dietary Approaches to Stop Hypertension) diet: This diet is specifically designed to lower blood pressure and includes plenty of fruits, vegetables, whole grains, nuts, and low-fat dairy products.
• Lacto-ovo vegetarian diet: This diet includes fruits, vegetables, legumes, nuts, seeds, whole grains, dairy, and eggs, while cutting out meat, fish, and poultry.
• Vegan diet: A strict form of plant-based diet that eliminates all animal products, including meat, dairy, poultry, eggs, and fish.
• Healthy Nordic diet: This diet is rich in whole grains, fruits, vegetables, legumes, fatty fish, and rapeseed oil, while limiting salt and sugar-sweetened products.
• High-fruit and vegetable diet: This diet focuses on increasing the consumption of fruits and vegetables.

The Impact on Blood Pressure

Research suggests that plant-based diets can significantly lower blood pressure compared to typical Western diets. In particular, the DASH diet and the lacto-ovo vegetarian diet have been found to be the most effective in reducing both systolic and diastolic blood pressure. The vegan diet may also help lower blood pressure, but the evidence is less conclusive.

Adopting a plant-based diet can lead to a rapid drop in blood pressure. Some studies have shown that just ten days of following a plant-based diet can reduce blood pressure by 10 mmHg or more. Additionally, adding regular exercise to your routine can further accelerate these results.

Other Health Benefits

In addition to lowering blood pressure, a plant-based diet has been linked to various other health benefits, including:

• Lower risk of heart disease, stroke, obesity, type 2 diabetes, and certain types of cancer
• Improved cholesterol and digestive health
• Weight loss
• Clearer skin
• Improved energy levels and reduced reliance on caffeine

Lower blood sugar

Lowering blood sugar is a key benefit of a vegan diet, especially for those with type 2 diabetes. A vegan diet can help improve blood sugar levels and insulin sensitivity, as well as aid weight loss. A 12-week study in 93 Korean people with diabetes found that a low-glycemic vegan diet resulted in slightly improved blood sugar management compared to a conventional diabetes diet. Another review of various plant-based diets, including vegan, found that they tended to reduce hemoglobin A1C by 0.8%. Hemoglobin A1C is a measure of blood sugar management over the previous 3 months and is a good indicator of long-term blood sugar management.

The benefits of a vegan diet for blood sugar management are due to the high fiber content of plant-based foods, which helps to slow the digestion of glucose and prevents spikes in blood sugar. Additionally, plant-based diets are typically lower in fat and calories, making it easier to lose weight, which in turn can help improve insulin sensitivity.

It is important to note that a vegan diet requires careful planning to ensure adequate nutrient intake and avoid deficiencies. For people with diabetes, it is crucial to work with a healthcare team, including a registered dietitian nutritionist, to determine the optimal amount of carbs and balance of nutrients in each meal.
