A caloric surplus can result in excess visceral fat. Unsurprisingly, visceral fat develops as a result of adopting unhealthy lifestyle habits. Some of these factors include:
Little or no exercise or avoiding functional exercises that build muscle
Poor diet high in carbohydrates, saturated fat, and empty calories
Poor sleep habits
Stress
Excessive alcohol consumption
Smoking
For people living sedentary lifestyles, it is quite easy to pick up several of these unhealthy habits. Over time, these habits will lead to increased amounts of body fat, including visceral fat.
