However, you should take several factors into account to ensure your diet is healthy and balanced.

Following a nutritious, well-rounded lacto-vegetarian diet can offer impressive health benefits.
Below are a few of the potential health benefits associated with this eating pattern.
Improves heart health
Multiple studies have found that lacto-vegetarian diets may improve heart health and decrease several common risk factors for heart disease.
Several other studies have found that vegetarian diets may be linked to reduced blood pressure. This is beneficial, as high blood pressure is a key risk factor for heart disease and stroke (4).
Promotes blood sugar control
Some research suggests that adopting a lacto-vegetarian diet could help enhance blood sugar control.
A review of 6 studies including 255 people linked vegetarian diets to significant reductions in hemoglobin A1c (HbA1c), a marker of long-term blood sugar control in people with type 2 diabetes (5).
Another review reported that following a vegetarian diet was associated with a lower risk of developing type 2 diabetes (6).
In addition, a study including more than 156,000 adults found that those who followed a lacto-vegetarian diet were 33% less likely to develop type 2 diabetes, compared with those who followed non-vegetarian diets (7).
Supports weight loss
Adopting a lacto-vegetarian diet may not only be good for your health but also your waistline.
A large review of 12 studies showed that people who followed a vegetarian diet for 18 weeks lost an average of 4.5 pounds (2 kg) more than non-vegetarians (12).
May reduce the risk of certain cancers
Numerous observational studies have found that following a lacto-vegetarian diet may be associated with a reduced risk of several types of cancer.
Notably, vegetarian diets have been linked to a 10–12% lower risk of developing cancer overall. They’ve likewise been linked to a reduced risk of specific types, including colorectal and breast cancer (13, 14, 15).
Keep in mind that these studies show an association, not a cause-effect relationship.
Further research is needed to evaluate whether following a lacto-vegetarian diet may help reduce your risk of cancer.
Summary Studies show that following a balanced lacto-vegetarian diet may help improve heart health, promote blood sugar control, aid weight loss, and reduce your risk of certain types of cancer.
A balanced lacto-vegetarian diet can supply all the nutrients your body needs.
However, without proper planning, it may increase your risk of nutritional deficiencies.

Filling your diet with whole foods like fruits, vegetables, whole grains, healthy fats, milk products, and plant-based, protein-rich foods will help ensure you’re getting the nutrients you need.
In some cases, a multivitamin or omega-3 supplement may also be necessary to help fill any gaps in your diet.
