Vegan Diet: When Will My Body Change?

There are a plethora of benefits to adopting a vegan diet, and you may start to see changes in your body in as little as 24 hours. One of the immediate benefits of a plant-based diet is heightened energy levels. This is due to the high intake of complex carbohydrates and antioxidants found in plant-based foods, which contribute to improved mood and vitality. In addition, the protein in meat is tougher for humans to break down than plant protein, which can cause sluggishness.

Within a few days, you may also notice a vegan glow, as the antioxidants found in fresh fruits and vegetables assist in shielding skin from cellular damage.

In the short term, a vegan diet can lead to weight loss, improved skin, and better digestive health. This is because plant-based foods are less calorie-dense and contain more fibre, which means you're probably eating fewer calories and eliminating more.

Over time, a vegan lifestyle can lead to lower cholesterol, reduced cancer risk, and a significant drop in heart disease risk. However, it is important to note that a vegan diet may also lead to certain nutrient deficiencies, such as vitamin B12 and omega-3 fatty acids, so it is important to consult a healthcare professional before making any significant dietary changes.

Increased energy levels

Switching to a vegan diet can lead to an increase in energy levels, although the exact mechanism behind this is unclear. One theory is that it results from the removal of processed meat, which is common in omnivorous diets, and its replacement with fruit, vegetables, and nuts. These plant-based foods are rich in vitamins, minerals, fibre, and complex carbohydrates, which provide the body with long-lasting fuel.

However, it is important to note that not everyone experiences increased energy levels on a vegan diet. Some people may feel more fatigued than usual, which could be due to a lack of balance in their nutrient intake. Maintaining optimal energy levels requires a proper balance of nutrients, including complex carbohydrates, healthy fats, protein, vitamins, and minerals.

To ensure sustained energy levels on a vegan diet, it is recommended to focus on consuming whole foods with adequate fibre and nutrient-dense vegetables and legumes. Combining macronutrients, such as carbohydrates with either fat or protein, can provide both instant energy and sustained fuel. For example, pairing an apple with peanut butter combines carbs, protein, and fat, resulting in a satisfying and energising snack.

Additionally, staying hydrated and getting adequate sleep are crucial for maintaining energy levels. Water helps keep energy levels up by preventing dehydration, while sufficient sleep ensures you are not burning the candle at both ends.

It is also worth noting that energy levels can be influenced by factors beyond diet, such as stress, lack of sleep, over-exercising, inadequate calorie intake, or nutrient absorption issues. If you are experiencing low energy levels despite a well-balanced vegan diet, it may be beneficial to consult a healthcare professional or a registered dietitian to identify any underlying causes.

Improved blood sugar control

A vegan diet can help improve blood sugar control, especially for those with type 2 diabetes or prediabetes. This is because plant-based diets are rich in fibre, which helps to slow the digestion of glucose and prevents spikes in blood sugar. Fibre also helps to reduce the impact of carbohydrates on blood sugar levels, as it makes meals more filling and satisfying.

Within just an hour of eating a plant-based meal instead of an animal-based one, you will be benefiting your health on a cellular level. The fibre, vitamins, minerals, and polyphenols in plant-based foods protect your body against diabetes and can help control your glucose levels.

Research has shown that a low-glycemic vegan diet can lead to slightly improved blood sugar management compared to a conventional diabetes diet. Another review found that diets that emphasised plant-based food intake, including vegan, vegetarian, and Mediterranean diets, tended to reduce hemoglobin A1C by 0.8%. Hemoglobin A1C is a measure of blood sugar management over the previous three months and is a good indicator of long-term blood sugar control.

Vegan diets can also help improve insulin sensitivity, which is key to maintaining normal glucose levels. Type 2 diabetes is characterised by insulin resistance, so increasing insulin sensitivity can help reduce blood sugar and insulin levels, as well as the need for insulin injections. Studies have shown that a low-fat vegan diet can lead to greater insulin sensitivity than a normal diet.

It is important to note that a vegan diet is not the only diet that can help manage diabetes. Other diets such as the Mediterranean diet and low-carb diet have also been shown to be effective. Additionally, it is crucial to consult a healthcare provider before making any significant changes to your diet, especially if you are taking insulin or other medications to control your blood sugar.

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:

• Clearer skin and a complexion free of acne.
• A reduction in wrinkles and fine lines.
• Increased hydration and brightness, with reduced scaliness.

These benefits are due to the anti-inflammatory nature of a vegan diet, which is typically low in fat and avoids pore-clogging saturated fats found in animal products. The vitamins and antioxidants in fruits and vegetables are the building blocks for radiant skin.

The effects of a vegan diet on skin health can be seen within a month. One person who adopted a vegan diet reported that their skin changed seemingly overnight from acne-prone to clear and healthy.

The link between a vegan diet and improved skin health is supported by scientific research. One study found that eating colourful fruits and vegetables improved skin health. These foods are sources of vitamins and antioxidant compounds such as anthocyanins, carotenoids, and polyphenols, which protect the body against inflammation.

In addition to the skin-clearing benefits of a vegan diet, the healthy unsaturated fats found in avocados and olive oil provide fatty acids that keep the skin hydrated and cell membranes strong and supple.

A vegan diet can also improve skin health by reducing the intake of dairy products, which are often a contributing factor to acne.

Improved gut health

A vegan diet can improve gut health by increasing the diversity of the gut microbiome. The gut microbiome refers to the collection of microorganisms in the digestive tract, which promote a healthy digestive tract, immune system, bowel movements, metabolism, and hormones that help with appetite regulation.

A healthy gut microbiome is a diverse microbiome, and a plant-based diet is the best way to achieve this. Research shows that 16 weeks of a vegan diet can boost the gut microbiome, helping with weight loss and overall health. A vegan diet is high in carbohydrates and fiber, which significantly reduces stool pH. This lower pH is strongly correlated with reduced counts of E. coli and Enterobacteriacea, species which are not tolerant of the more acidic environment.

A vegan diet can also reduce inflammation, which is the key feature linking the gut microbiome with protective health benefits. The vegan gut profile is unique in several characteristics, including a reduced abundance of pathobionts and a greater abundance of protective species. For example, vegans have a higher ratio of Faecalibacterium prausnitzii, an anti-inflammatory bacterium and abundant butyrate producer, which is purported to play a protective role for colonocytes.

The vegan gut profile also appears to be protective against metabolic syndrome. Obesity is associated with an altered gut profile, where resident bacteria may be responsible for an increased capacity for energy harvest and a state of chronic, low-grade inflammation. This inflammation can interfere with insulin signaling and results in the metabolic dysfunction found in obesity and type 2 diabetes. A vegan diet is associated with a higher ratio of the Bacteroides-Prevotella group, which is linked to a diet high in carbohydrates and a vegetarian diet. This group increases in abundance with a vegetarian or vegan diet and has been shown to increase in response to a vegan diet.

In addition, a vegan diet is associated with a decrease in pathobionts such as Enterobacteriaceae, a family of bacteria implicated in triggering low-grade inflammation. The vegan diet directly reduces the population of pathobionts, thereby reducing inflammation and contributing to improved glucose tolerance and lipid metabolism.

A vegan diet can improve gut health by increasing the diversity of the gut microbiome, reducing inflammation, and altering the abundance of certain bacteria. These changes can lead to improved glucose tolerance, lipid metabolism, and overall health.

Lower cholesterol levels

A vegan diet is an effective way to lower your cholesterol levels. Cholesterol is a waxy substance produced by the liver that helps build cell membranes and produce hormones. While cholesterol is essential, our bodies produce enough of it, so we don't need to consume it through our diets.

Cholesterol is transported through the bloodstream by carriers called low-density lipoproteins (LDL) or high-density lipoproteins (HDL). LDL cholesterol, often referred to as "bad cholesterol", can increase your risk of a heart attack if levels are too high. HDL cholesterol, on the other hand, is known as "good cholesterol" as it helps clear LDL cholesterol from the arteries.

A vegan diet can help lower LDL cholesterol levels and increase HDL cholesterol levels. This is because a vegan diet is typically lower in saturated fat, cholesterol, and total fat, and higher in healthy unsaturated fats. Research has shown that plant-based diets lower cholesterol levels more effectively than omnivorous diets.

Within just one week of adopting a vegan diet, you may see a drop in your cholesterol levels. A group of firefighters who participated in the documentary "The Game Changers" celebrated a decrease in their cholesterol after just seven days of eating only plants.

However, it's important to note that not all vegan diets are created equal. A diet high in refined carbohydrates and sugars, as well as one that includes excessive amounts of coconut and palm oils, can lead to elevated cholesterol levels.

To optimize your cholesterol levels on a vegan diet, focus on consuming whole foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds. Reduce your intake of processed foods, especially those high in saturated and trans fats, sugars, and sodium. Prioritize healthy fats like avocados, olive oil, and flaxseeds.

In addition to dietary changes, regular physical activity is crucial. Engage in at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise weekly. Strength training exercises for all major muscle groups are also recommended two or more days a week.

By adopting these lifestyle changes, you can effectively lower your cholesterol levels and reduce your risk of heart disease.
