Can Oatmeal Help in Weight Gain?

Can Oatmeal Help in Weight Gain

Oatmeal alone is not typically considered a food that promotes weight gain. In fact, oatmeal is often recommended as a food that can aid in weight loss due to its high fiber content and ability to promote feelings of fullness.

However, if you are looking to gain weight, you need to remember to create a calorie surplus in your diet. Ideally, this should be done by consuming nutrient and calorie-dense foods that are not ultra-processed and give you a ton of micro and macronutrients.

It is also crucial to make sure you need your protein goals daily as it will help you gain muscle and not just fat


Oatmeal can be a healthy addition to your diet when paired with other nutrient and calorie-dense foods. One way to increase the calorie content of oatmeal is to add healthy fats, such as nuts, seeds, or nut butter, which can help increase the overall calorie and nutrient content of the meal.

Role of Fiber in Weight Management

Role of Fiber in Weight Management

Oats have a high amount of beta-glucan – a natural fiber that promotes fullness while being light in calories. Beta-glucan fiber triggers the release of peptide YY in the small intestine, which reduces overeating. 

While fiber doesn’t directly contribute to weight gain, consuming high-fiber foods can help you manage your weight gain effectively.

Fibre adds bulk to your diet without extra calories, making you feel fuller. Additionally, fiber-rich foods like oatmeal have a low glycemic index, which helps regulate spikes in blood sugar levels, significantly reducing cravings. 

All this helps you gain a ‘healthy weight’ from nutritious foods, rather than the unwanted extra fat.

You should avoid packaged oatmeal products because they often contain added sugars and preservatives, which are detrimental to your health.

These ingredients increase the calorie content of the oatmeal and contribute to weight gain. However, this weight gain isn’t ideal as it will lead to you putting on fat and not muscle.

What Are the Benefits of Consuming Oatmeal?

As discussed, oats is a super healthy ingredient to include in your diet. Here are some common benefits: 

1. Improves Heart Health by Managing Cholesterol Levels

Improves Heart Health by Managing Cholesterol Levels

Oatmeal contains a soluble fiber called beta-glucan, which helps control cholesterol levels. 

When consumed, beta-glucan forms a gel-like substance in the small intestine, which binds with the bile acids.

The viscous gel structure (along with the bile) is eliminated from the body as it can’t be reabsorbed in the bloodstream. Since a major component of bile is cholesterol, eating high-fiber food like oats can lower blood cholesterol levels. 

Multiple studies have shown that oatmeal can help reduce your LDL cholesterol without affecting HDL cholesterol.

2. Controls Blood Sugar

Controls Blood Sugar

Adding oatmeal to your diet can regulate blood sugar levels and helps improve insulin sensitivity. This is thanks to the moderate to high amount of fiber and the low glycemic index of oats. 

3. Relieves Constipation 

Relieves Constipation

Being rich in fiber (both soluble and insoluble), oatmeal is often considered to be effective against constipation and promotes bowel regularity. 

The beta-glucan present in oats dissolves in water to form a gel-like substance in the gut, thereby softening the stool and making it easy for it to pass. Moreover, it also helps avoid constipation. 

4. Reduces Risk of Childhood Asthma

Reduces Risk of Childhood Asthma

Oatmeal consumption has been linked to a reduced risk of childhood asthma, likely due to its high content of beta-glucan fiber. 

Beta-glucan has been shown to have anti-inflammatory effects, which can reduce airway inflammation associated with asthma. According to a study published by Cambridge University, early introduction of oats in your diet is often associated with a decreased risk of asthma. 

5 May Reduce the Risk of Certain Diseases

In general, weight gain occurs when you consume more calories than your body burns. Adding oatmeal to your diet can provide a healthy source of complex carbohydrates, fiber, and nutrients that can help support overall health while contributing to weight gain when paired with other calorie-dense foods. 

However, it is essential to consult with a healthcare provider or registered dietitian to ensure that you meet your nutritional needs and gain weight healthily.
