Belly Fat Basics

belly fat can be the most stubborn to get rid of

What causes that nasty fat around our bellies that seems like it’s impossible to lose? Well, there are a few things that contribute to belly fat.

Some of these things include living a sedentary lifestyle.

Maybe you went through a time in your life where you were eating too much and moving too little.

Maybe you’re still there.

We all have our struggles; we just have to learn to work around them.

Some of the primary causes of belly fat in both men and women have been determined to be lifestyle choices such as a reduction in exercise and poor eating habits.1

Another contributing factor could also be your age. As we age, our bodies tend to lose muscle mass and increase fat.

It’s an unfortunate side effect of aging that many of us fight against.

Why is Belly Fat So Hard to Lose?

There are a lot of contributing factors as to why belly fat is so hard to lose.

We mentioned earlier that the largest factor is often your diet and exercise routines but there could be underlying issues.

What you need to understand is that having excess fat, particularly belly fat is known for leading to things like cancer, heart disease, and diabetes.

There are a multitude of health ailments that are related to obesity and belly fat in particular.

If you’re struggling to lose belly fat, it could be related to some of these things.

  • Age
  • Diet and exercise
  • Hormones
  • Excessive alcohol consumption
  • Stress
  • Lack of sleep
  • Underlying health conditions
  • Lack of motivation
  • Low training intensity2

There are also circumstances in which you might struggle with belly fat because it is part of your genetics.

Losing belly fat is not impossible but it may definitely be challenging.

When you lose fat, you can’t restrict the fat loss to one specific area of your body.

However, you can target your body with exercise and there are things you can do to help with fat in general.3

Belly fat is not totally controllable, as much as we wish it were. 

You just need the resources to help you make some progress.

Nothing beats appropriate diet and exercise but supplements can help to fuel your body to properly knock out belly fat.

Now – let’s take a look at the best supplements for belly fat.
