Many people assume that anyone who relies on medication for weight loss may be lazy or unwilling to put in effort. While lifestyle is a big factor in how much someone weighs, genetics and physiology also play a role. Due to different body chemistry, some are more likely to be overweight than others. Medications, such as Phentermine and Saxenda, can help fix chemical imbalances in the body that cause excessive weight gain. Their effects are modest, usually resulting in a loss of no more than 10% of a person's body weight. With the right combination of diet, exercise, and proper medication, one can have a successful weight loss journey.
