Weight Loss Q & A

Why should I maintain a healthy body weight?

Did you know that more than 1 in 3 adults in the United States are overweight or obese? Being overweight impacts your health in a variety of negative ways. When you’re overweight, you’re more likely to develop high blood pressure and high cholesterol levels, both of which increase your risk of having a heart attack or stroke.

Being overweight also boosts your chances of developing a variety of serious chronic illnesses, including:

  • Type 2 diabetes
  • Heart disease
  • Obstructive sleep apnea
  • Gallbladder disease
  • Certain types of cancer
  • Osteoarthritis

Luckily, losing just 5%-10% of your body weight and maintaining a healthier number on the scale can substantially reduce these risks and protect your long-term health.

What is a medical weight loss program?

Dr. Comstock takes a comprehensive, customized, whole-person approach to weight loss, providing the specific resources, tools, and support you need to achieve long-term results.

At its core, the nonsurgical medical weight loss program at Lifestyle Spectrum centers around proven strategies that help you identify and break the habits that prevent weight loss, give you proper nutrition and increase your level of activity.

During your initial health assessment, Dr. Comstock's team will perform a comprehensive physical exam, including an EKG, body composition analysis, and full laboratory evaluation. Dr. Comstock will review your medical history with you, considers your lifestyle, and discusses any health concerns you may have.

Your program will include a customized diet plan that takes your baseline nutritional needs into account; a personalized, goal-oriented fitness plan designed to maximize your results with weekly office visits.

Depending on your individual needs, your program may include supplements that enhance your body’s ability to burn fat.

Why are diet and exercise so important?  

The weight loss program at Lifestyle Spectrum is so successful because it combines proper nutrition, physical activity, regular office visits, and support to help you reach your weight loss goals in a safe, sustainable way.


Dr. Comstock begins most patients on a nutrient-dense, low-carbohydrate diet to help initiate the weight loss process. Because Dr. Comstock believes that the simple act of changing your diet can change your life, he strives to improve his weight loss patients understanding of the pivotal role diet plays in health and aging. 

A nutritious diet focuses on whole foods, including healthy proteins, fats, and carbohydrates, while limiting processed foods and added sugars. 

Many of Dr. Comstock’s patients find that they can accelerate the fat-burning process with Lifestyle Spectrum’s ketogenic approach. Nutritional Ketosis is reached by eliminating foods from your diet that load you up with glucose, and increase your body fat, and instead, consuming foods that promote fat-burning metabolism naturally.

Maybe you’ve wondered about the Paleo diet? This grain-free and dairy-free diet excludes anything that your caveman ancestors couldn’t have eaten, so you enjoy the healthy proteins, fats, and carbohydrates found in unprocessed, natural foods for enhanced metabolism and weight-loss results. You eliminate refined carbohydrates on your way to weight loss.
