In the quest for a trimmer waistline, your choice of milk can play a pivotal role. Enter coconut milk and oat milk, two popular contenders of plant-based milks or dairy alternatives. But which one should you pour into your weight loss journey?

In this article we’ll navigate the nutritional waters of coconut milk vs oat milk for weight loss to help you make an informed decision. Get ready to discover which creamy companion can best support your path to a healthier you.

Coconut Milk For Weight Loss

Coconut milk contains medium-chain triglycerides (MCTs), fats the body can absorb quickly and use for quick energy. Some research suggests that MCTs can help in excess calorie burning, thus aiding in weight loss. However, it’s important to note that coconut milk is also high in calories and saturated fats, so it should be consumed in moderation, especially when the goal is weight loss1.

To utilize coconut milk for weight loss, people often substitute it for other high-calorie ingredients in recipes, add it to smoothies, or consume it in small amounts to promote feelings of fullness. It’s typically part of a broader weight-loss plan that includes regular exercise and a balanced diet rich in fruits, vegetables, lean proteins, and whole grains.

Potential Benefits Of Coconut Milk

Coconut milk is a rich liquid made by blending coconut flesh with water. While it’s often used in cooking and baking, some people believe it can aid in weight loss2. However, it’s essential to note that scientific evidence on this subject is limited.

That said, here are some of the potential benefits of unsweetened coconut milk:

Effects on Weight and Metabolism

There are small amounts of MCTs in coconut milk. MCTs may speed up your metabolism and help you lose belly fat. However, because the MCTs present are relatively modest quantities, the impact of these on your weight loss journey is likely to be marginal3,4,5,6.

Effects on Cholesterol and Heart Health

Many individuals may have concerns regarding the heart-healthy attributes of coconut milk, primarily because it contains a significant amount of saturated fat. It is worth noting that the research on the impact of coconut milk on heart health is somewhat limited. However, there is one study that hints at potential benefits, indicating that coconut milk may be beneficial for individuals with either normal or high cholesterol levels7,8,9.

Helps Control Diabetes

The virgin coconut oil that is prepared from coconut milk has been shown to affect blood glucose levels positively. It contains antioxidant properties that improve insulin secretion in the body10.

Antioxidant Protection from Disease

The antioxidants in coconut milk, specifically phenolic antioxidants, are known to protect the body from this oxidative damage. They do this by interacting with and neutralizing reactive oxygen species (ROS) and by inhibiting enzymes that create inflammation, which can lead to health problems like cancer11.

Potential Side Effects Of Coconut Milk

While coconut milk has some potential benefits, there are also potential side effects and drawbacks to consider, especially in the context of weight loss:

Coconut Allergy

Though rare, some people are allergic to coconut and should avoid coconut milk. Symptoms can range from skin rashes to more severe reactions like anaphylaxis12.

May Lead to High Cholesterol

Due to its high saturated fat content, those at risk of elevated cholesterol and cardiovascular disease should limit their consumption of coconut milk13.

High In Calories

The caloric content of one cup of coconut milk, totaling 552 calories, remains constant. This significant caloric load constitutes nearly one-third of the recommended daily caloric intake. Nevertheless, it is essential to exercise caution when considering daily consumption of coconut milk, as it may have potential adverse effects on one’s health.

Oat Milk For Weight Loss

Oat milk is a plant-based option for cow’s milk. It is made from crushed oats blended with water and filtered to remove the oat bran. Additionally, enzymes can be incorporated to further break down the starch content if desired.

When using oat milk for weight loss, individuals typically choose unsweetened varieties to minimize calorie intake and often use it as a substitute for higher-calorie dairy milk or other beverages in their meals and recipes

Potential Benefits Of Oat Milk

While oat milk is not as protein-rich as cow’s milk or as fat-rich as coconut milk, it offers various nutritional and health benefits, making it a popular choice for many people.

Here are some potential benefits of oat milk:

Low in Fat

Oat milk generally contains less fat than cow’s milk, making it a lighter option14.


As a plant-based beverage, oat milk is devoid of cholesterol, rendering it a heart-healthy alternative15.

High in Fiber

Oats are naturally high in soluble fiber, and while oat milk is not as fiber-rich as whole oats, it still contains a modest amount of fiber that can aid digestion and provide a feeling of fullness.

Rich in Vitamins

Commercial oat milk is fortified with vitamins like A, D, and B12. Incorporating these vitamins into your diet can potentially assist in managing stress, combating oxidative damage, and promoting the health of your hair, nails, and skin16,17,18.

Bone Health

Fortified oat milk contains calcium and vitamin D, crucial for maintaining healthy bones.

Blood Sugar Control

The fiber present in oat milk can play a role in stabilizing blood sugar levels, but it’s essential to choose options that do not contain added sugars.

Regulate Blood Pressure 

Oat milk’s potential to regulate blood pressure may contribute to overall heart health. Rat studies suggest that the globulin peptide found in oat milk may have a role in modulating blood pressure19.

Enhancing the Immune System

Oats contain bioactive peptides that may boost immunity. It may boost innate immunity (the immune system’s first response to foreign chemicals) and adaptive immunity.

Potential Side Effects Of Oat Milk

While oat milk is generally considered safe for most people and has various benefits, there can be some potential side effects or drawbacks to consider:

Calories and Sugar

Some commercial oat milk contains added sugars and is higher in calories. Always check the nutritional label if you’re watching your sugar intake or are on a calorie-restricted diet.

Digestive Issues

Oats contain fermentable carbohydrates that could be problematic for people with irritable bowel syndrome (IBS).

Gluten Contamination

While oats are naturally gluten-free, they are often processed in facilities that handle gluten, posing a risk for those with celiac disease or severe gluten sensitivity. Some brands offer gluten-free oat milk, but reading labels carefully is essential.

Oat Allergy

Although uncommon, there are individuals who have oat allergies and should steer clear of oat milk.


Those with allergies to other grains like wheat or corn may also experience cross-reactivity with oat products.

Added Ingredients

Commercial oat milk often contains added vitamins, minerals, and sometimes stabilizers, gums, or oils. If you’re sensitive to these additives, look for brands with minimal ingredients or make yourself some homemade oat milk.

Fortification Variability

Not all oat milk is fortified with vitamins and minerals. If you rely on it as a calcium or vitamin D source, choose a fortified version or get these nutrients from other sources.

Coconut Milk vs Oat Milk For Weight Loss: Main Comparison

Choosing coconut and oat milk can depend on several factors, such as caloric content, fat content, fiber, protein, and how to use them. Here is a detailed comparison:

Nutritional Content

Coconut Milk:

  • Calories: Coconut milk is quite calorie-dense, especially if you’re using the canned variety often used in cooking. However, the carton varieties meant for drinking generally have fewer calories.
  • Fats: It is high in saturated fats, which are not ideal for weight loss or heart health if consumed in large amounts.
  • Carbs & Protein: It is relatively low in carbohydrates and protein.

Oat Milk:

  • Calories: Oat milk typically has fewer calories than canned coconut milk but more than carton coconut milk meant for drinking.
  • Fats: They are lower in fat than coconut milk, and the fats are generally healthier.
  • Carbs & Protein: Higher in carbohydrates but also contains some fiber, which can help you feel full. It has a modest amount of protein.


  • Coconut Milk: The higher fat content may provide a feeling of fullness but lacks fiber.
  • Oat Milk: The fiber and protein content can contribute to satiety, which may help control appetite and thus aid in weight loss.

Dietary Restrictions

  • Coconut Milk: Suitable for those who are nut-allergic or grain-sensitive.
  • Oat Milk: This is a good option for those who are lactose intolerant, nut-allergic, or soy-sensitive, but it is not ideal for those who are sensitive to grains.

Versatility in Recipes
