How Does Food Actually Turn Into Fat in the Body?

Hey Angels and Alphas,

While pretty much everyone would prefer to have a strong set of abs and a lean physique, our bodies have taught themselves to naturally store fat around certain areas of the body like the stomach area. While it may be frustrating, the process behind how food turns into belly fat is deeply rooted in our metabolism, hormones, and genes.

Let’s dive into the mechanisms that dictate where our excess calories go… and learn how to use them to our advantage to limit the amount of fat we store.

Metabolism and Weight Gain: A Closer Look

Weight gain essentially occurs when you consume more calories than your body can burn throughout the day. Your calorie burn is mainly influenced by three factors:

Basal Metabolic Rate (BMR): This refers to the energy required for basic bodily functions, such as powering your heart, brain, and cells. It accounts for 60 to 80 percent of your metabolism and remains fairly constant, even during sleep.

Physical Activity: Including exercise, walking, and fidgeting, it contributes to 10 to 30 percent of your calorie burn.

Thermic Effect of Food (TEF): The energy used to digest food comprises about 10 percent of your metabolism.

When caloric intake surpasses the combined energy expenditure from these factors, the body stores the excess calories either as muscle (lean mass) or as fat. While many might prefer the calories to go towards muscle growth, the body requires a stimulus, such as exercise, to direct the calories accordingly.

Why Belly Fat?

The accumulation of fat in specific areas like the belly is influenced by both heredity and hormones. You can’t choose where the fat goes, but you can influence the hormones that guide fat storage, namely insulin and cortisol.

Insulin: It acts as a regulator, directing sugar from the bloodstream into cells. While insulin is essential for storing calories as muscle, consistently elevated insulin levels, often resulting from a diet high in sugar, can lead to fat storage.

Cortisol: Known as the stress hormone, cortisol prepares the body for a fight or flight response. Chronic stress or lack of sleep can lead to elevated cortisol levels, which is linked to belly fat accumulation.

How to Limit Fat Gain

Choose Quality Calories: A diet rich in vegetables, fruits, whole grains, and lean proteins can be more fulfilling and less likely to contribute to belly fat. High-quality calories are less likely to spike blood sugar levels and hence, lead to less insulin release.

Control Your Cortisol: Managing stress through practices like controlled breathing, limiting caffeine and alcohol intake, and practicing relaxation techniques can help keep cortisol levels in check.

Prioritize Sleep: Lack of sleep can disrupt hormonal balance, making fat storage more likely. Ensuring adequate sleep is crucial for maintaining a healthy weight.


In conclusion, understanding the mechanisms of how food transforms into belly fat offers insight into effective strategies for managing weight and maintaining health.

And not only that but understanding the relationship between food, metabolism, hormones, and fat storage can empower us to make informed choices.

While it may seem like a complex battle, making simple changes in lifestyle and diet can significantly impact how and where your body stores fat. By doing this, we as individuals can foster an environment within our bodies that favors health, vitality, and longevity.
