The latest fad diet may sound like the answer to excess weight. Take this pill, drink this shake, or follow this menu, and the pounds will melt away.

You have a better, safer option with sustainable results with our medical weight loss programs. At Tseng Plastic Surgery in Bellevue and Kirkland medical weight loss is physician-supervised and designed to help you shed pounds while enhancing your overall wellness.

Medical Weight Loss Kirkland and Bellevue


Given the rising obesity rates in this country, one would expect weight loss to be an incredibly challenging endeavor. In truth, most people can take off a few pounds without much difficulty, and the more excess body fat you have, the more quickly it comes off. The problem is not losing weight but keeping it off and, even more importantly, staying healthy while doing so.

Many rapid weight loss diets deprive the body of essential nutrients, making them detrimental to health rather than beneficial. Furthermore, dieters tend to resume their old habits when giving up on an intolerable program or after reaching their weight goals.


Medical weight loss is not like a typical “diet.” It does not encourage dangerous food deprivation or imbalanced dietary habits. It is not a temporary deviation from your normal routine that ends when the weight comes off. Instead, it is a customized program that helps you improve health while slimming. Furthermore, it teaches you to adapt healthy long-term habits for nutritious and satisfying eating that does not pack on the pounds.


Dr. Tseng has taken the guesswork out of medical weight loss by implementing the InBody body composition system to evaluate your progress. We can, with the highest level of precision, track fat loss and muscle gain to better manage your weight loss journey.

  • Body composition analysis every month and lab work on a quarterly basis
  • Evaluation and monitoring of metabolic rate hydration, lean muscle mass, thyroid hormone, body fat percentage, coronary health, kidney and liver functionality, and more
  • Medical supervision and guidance, with weekly appointments in the first phase and monthly thereafter
  • A personalized diet plan, including portion control and meal planning assistance
  • Lifestyle coaching to help you adopt healthy habits and meaningful behavioral changes
  • Education about nutrition, exercise, and habitual behavior that empowers you to take control of your health and weight
  • Optional adjunct cosmetic procedures to eliminate stubborn localized fat, remove excess skin, and refine your figure
