Why We Gain Weight

With the advent of technology, the nature of work and leisure has shifted dramatically. Jobs that once involved manual labor have been replaced by those that require sitting at a desk for long hours. Entertainment, too, often involves passive activities like watching TV or playing video games. This lack of physical activity can result in fewer calories burned throughout the day, leading to weight gain.

The American diet has seen a shift from home-cooked meals to processed and fast food. These types of foods are often high in sugars, unhealthy fats and salt, but low in essential nutrients. Portion sizes have also grown with super-sized options becoming the norm. As a result, many Americans consume more calories than they need.

Unhealthy food options, especially fast food can be cheaper and more accessible than fresh, nutritious foods. For many families, especially those in low-income brackets, it can be more economical to purchase calorie-dense, nutrient-poor foods than to invest in healthier options. 

The way our cities and neighborhoods are designed plays a role in our activity levels. Many places in the U.S. are built for cars rather than pedestrians or cyclists. The lack of sidewalks, parks and recreational areas can discourage physical activity. Furthermore, some areas, often referred to as “food deserts,” lack access to stores that offer fresh, healthy food options.

Stress, depression and other mental health issues can contribute to weight gain. Some people eat as a way to cope with emotions or use food as a source of comfort. Additionally, lack of sleep, which is common among Americans due to high-paced lifestyles and increasing screen time can lead to hormonal imbalances that stimulate hunger and reduce feelings of fullness.

The food industry spends billions of dollars on advertising, much of which is directed towards promoting unhealthy foods and beverages. This constant exposure can shape preferences and influence consumer choices, making it challenging for individuals to make healthy decisions consistently.

The way society views food and eating habits can influence individual choices. Celebrations, holidays and social gatherings often revolve around food with an emphasis on quantity and indulgence. Over time, these norms can normalize overeating and choosing unhealthy foods.

Some medications, including certain antidepressants, antipsychotics and hormonal treatments can lead to weight gain. Additionally, medical conditions like hypothyroidism, polycystic ovary syndrome (PCOS) and Cushing’s syndrome can influence body weight.

While lifestyle choices play a significant role, genetics can also influence how easily someone gains or loses weight. Some people might be genetically predisposed to have a slower metabolism or to store fat more efficiently.

While there’s a wealth of information available about nutrition and health, not everyone has access to or understands this information. Schools, communities and families play a role in educating individuals about making healthier choices.
