10 Reasons a Vegetarian Diet Helps with Weight Loss and Health
By Rebecca Walton, Service Director
Vegetarians tend to be healthier, live longer and are less likely to become obese than their meat-eating counterparts, and a vegetarian diet can be just as good as a meat based one. However, it's important to remember that the quality of your diet still counts!
While eating a vegetarian menu can help you lose weight and reduce the liklihood of obesity and other chronic disease risks, going veggie doesn't guarantee weight loss - calories from plant based foods count just as much as those from meat and fish.
A diet full of veggie or vegan junk food won't help your weight or make you healthy. For an idea of how to lose weight on a veggie diet, take a look at our vegetarian weight loss meal plan.
So is Being Vegetarian Healthy?
The evidence shows that eating a balanced vegetarian diet has huge health benefits! However, it's important to take into account the types of food you eat. You'll still need to moderate highly processed foods packed with fat, sugar and calories to maintain a healthy diet.
Top 10 Benefits of a Vegetarian Diet
Our 10 science-backed benefits might be just enough to encourage you to give vegetarianism a try! (With even more resources to get you off to a good start below the list...)
1. Live longer...
Recent studies1 have shown that following a vegetarian diet improves your mortality rate by up to 12%!
Following a vegetarian diet can increase your life span and lower your risk of death. All of the health benefits mentioned below accumulate to improve mortality, decreasing your risks of chronic illnesses. You’ll be surprised by how much a meat free diet can help your body inside and out!
2. Lose more weight...
According to a study published in the Journal of the American College of Nutrition2, you could potentially lose twice as much weight following a vegetarian diet...
Researchers found that a vegetarian diet resulted in an average loss of 6.2kg compared to 3.2 kg for a conventional diet.
3. Lower your blood pressure...
Fruits and vegetables are low in sodium but rich in potassium, characteristics that help to lower blood pressure... 32(!) different studies3 have shown that following a vegetarian diet can lead to lower blood pressure compared to an omnivorous diet.
4. Lower your cholesterol...
Further studies found that4 plant based vegetarian diets are commonly associated with lower cholesterol levels due to reduced intake in saturated fats and an increased intake of plant based foods.
Researchers believe the link between vegetarian diets and lower cholesterol is due to lower saturated fat intake and increased consumption of plant foods that are naturally rich in components such as fibre, soy protein and plant sterols.
Why not try introducing more meat free evening meals like this vegetarian cottage pie?
5. Lower your risk of heart disease and strokes...
A new study5 which analysed almost half a million Europeans found that people who followed the most pro-vegetarian diets had a 20% lower risk of dying from cardiovascular disease.
High cholesterol and blood pressure play an important role in the prevention of heart disease and we already know that following a vegetarian diet lowers your blood pressure and cholesterol (see points 3 and 4 above). Results clearly showed that the risk of heart disease in vegetarians is about a third lower compared to non vegetarians6.
6. Lower your risk of type 2 diabetes...
Specialist diabetes researchers have shown that a healthy vegetarian or vegan diet can help to protect against type 2 diabetes, showing a 50% increase in prevention!
A vegetarian diet rich in plant based foods is low in fat and supplies your body with fuel that helps to contribute to more stable blood sugar7.
7. Lower your risk of bowel and colon cancer...
Many people are already aware that eating less red or processed meat, regardless of if you chose vegetarianism or not, can reduce your risk of colon and bowel cancer.
But did you know, a recent study from the University of California has shown8 those who follow a vegetarian diet can reduce their risk of colon cancer by up to 22%!
8. Lower your risk of becoming obese...
A vegetarian diet could cut your risk of becoming obese by up to 43%9 supporting recommendations to make the shift to diets rich in plant foods, with lower or no intake of animal foods.
9. Protect yourself against common bowel disorders...
Vegetarians are a third less likely to get diverticular disease – a common bowel disorder.
The University of Oxford’s researchers10 believe this could be due to the increased amount of dietary fibre consumed within a vegetarian diet.
10. Helps with chronic kidney disease...
Individuals with kidney disease must limit their amount of phosphorous intake and clinical studies11 have shown that following a vegetarian diet can help this.
Patients following a vegetarian diet had lower blood phosphorus levels compared to those on a meat-based diet according to the Clinical Journal of the American Society Nephrology.
