Will Eating Oatmeal Help You Lose Weight?

The phrase “breakfast is the most important meal of the day” has been drilled into our heads by magazines, nutrition articles, and health bloggers. But, very few of them discuss exactly what you should be eating for breakfast.

If you’re looking to lose weight, then the popular options including French toast, waffles, pancakes, and muffins might need to take a backseat. But, that still leaves you with eggs, smoothies, and a host of other options. If you’re looking for something that’s going to optimize your diet, oatmeal might be the way to go.


Why Choose Oatmeal?

Oats promote satiety and regulate hunger.

A recent study places oatmeal above a few conventional breakfast options. In it, three different breakfast options were tested on 36 participants, 18 lean and 18 overweight, in a randomized sequence. The three options were oatmeal, cornflakes, and water. All participants had the same lunch across all the three options.


Hunger and satiety were measured at the end of each sequence with the help of a blood test that looked at levels of glucose, insulin, glucagon, and leptin (the hunger hormone). Satiety was the highest with the consumption of oatmeal, especially in the overweight participants. This also leads to them losing weight more efficiently.1 Oatmeal owes this to a set of specific benefits that contribute to satiety and hunger-regulation.

Benefits Of Oatmeal

Oats are rich in fiber, protein, and nutrients.


1. High Fiber Content

A bowl of oats provides 16.5 grams of fiber.2 Fiber plays an important role in maintaining weight. It does this by promoting satiation, maintaining glucose levels, and preventing overeating.3 Besides this, fiber content in oatmeal aids in healthy bowel movements. So, if you’re looking for a breakfast option that doesn’t leave your stomach growling until you get to lunch, go for a bowl of oatmeal.4

2. High Protein Content

Most fitness articles and videos use the word “protein” at least once. When it comes to weight loss, high protein diets are linked to improvements in appetite and body weight management. It also has a positive impact on metabolism. One bowl of oats gives you 26.35 grams of protein!5 To add to this, protein is an important macro nutrient if you’re working out. So, skip the eggs and pick up a bowl of oatmeal instead.6


3. Nutrient Content

Just because you’re aiming to lose weight doesn’t mean you miss out on adequate nutrition. In fact, healthy weight loss comes with a reduced calorie, nutritionally-balanced eating plan.7 And, oats make for a great addition to this plan since they are rich in manganese, selenium, phosphorus, magnesium, and zinc. They are also rich in vitamin E.8

In addition to this, oats are rich in phytochemicals which might aid weight loss and control obesity.9


Note: It’s important to opt for instant oatmeal over ready to eat oat breakfast cereal. The latter, including granola and energy bars, might have added sugar that will cause insulin spikes and make you crave more sugary foods. This will eventually disrupt your diet and lead to weight gain.10
