20 Low Calorie Foods to Aide in Weight Loss and Nutrition

According to the Centers for Disease Control and Prevention (CDC), over 73% of adults over the age of 20 are overweight or obese in the United States. Yes we are in a good place to be able to have available medicines like Semaglutide, Wegovy, Ozempic, Mounjaro and Tirzepatide to help combat obesity.

Obesity is correlated with an increase in risk for many serious diseases and health conditions. Some diseases including but not limited to are heart disease, stroke, diabetes, chronic pain, Alzheimer’s disease, cancer, and poor mental health.
