Quarantine weight gain FAQ and statistics

What is the '"Quarantine 15"?

The "quarantine 15" is the new "freshman 15"; It is referring to the excess weight gain that people experience during long bouts of isolation, stress, and reduced physical activity.  


Why are people gaining weight during the pandemic?

When the lockdowns started due to the COVID 19 pandemic, each person felt the effects of having their daily routine and healthy habits disrupted. Many people's exercise routine was upended, especially those who play sports or relied on the gym. With activity levels low and living a more sedentary lifestyle, it makes sense that people are struggling with weight.

Also, stress levels are at an all-time high due to the pandemic itself, as well as having fewer outlets to reduce our stress. On top of being a general mental health concern, these stress levels can spark emotional eating. This can push us towards eating less healthy foods, whether it's comfort food, ultra-processed foods, or junk food.
