Obesity is rising among college students, with three out of ten found to be overweight or obese. Obesity is defined as a BMI over 30% and can cause health issues like high blood pressure and diabetes. College students may be gaining weight due to unhealthier lifestyles than in the past and developing unhealthy relationships with food. Their eating habits include consuming more carbonated drinks and high-sugar foods instead of the recommended fruits and vegetables. Psychological influences can also contribute to obesity by impacting self-esteem and distorting perceptions of food.
