The Thoman Tube Diet

Dr. David Thoman has helped develop a system for rapid weight loss in Santa Barbara that can help you lose a significant amount of weight in just 10 days. With this system, a very small feeding tube is placed into the stomach and worn 24 hours a day for 10 days. This tube suppresses the appetite while providing the body with all the nutrients it needs through the constant delivery of a special, protein-rich formula. As this treatment stimulates your metabolism and promotes the breakdown of fat, you can watch your body become leaner and healthier.

How it works

The Thoman Tube Diet combines medical ketogenesis and metabolic stimulation to rapidly break down excess fat. Dr. Thoman’s exclusive protein-based formula was developed during his 20 years of medical diet research. The formula contains no carbohydrates or fat, so it will cause the body to begin ketogenesis (using existing stored fat for fuel) within 48 hours. Because the body is still being supplied with essential nutrients, your metabolism keeps working to convert fat into energy even though you are not eating. After a 10 day cycle a 2 week “rest period” of healthy eating can be followed by another cycle. This can be repeated as often as needed until goal weight is achieved. The tube is also helpful for weight maintenance by using once to twice per year to lose any added weight


  • Safety – Less invasive than surgical weight loss treatments
  • Affordability – Costs less than gastric bypass or LAP-BAND® surgery
  • Flexibility – The tube is removed in 10 days, and can be replaced at intervals for maintenance
  • Effectiveness – Loss of up to 10% of your body weight

Risks and complications

We provide close medical supervision to ensure the safety of our patients while they are on the diet. Pre- and post-diet blood work and physical exams help monitor your health before, during and after the weight-loss process. The most common side effect is a sore throat from the tube which is usually easily managed. Ketosis can also result in bad breath. More serious side effects from ketogenesis are avoided by limiting the procedure to 10 days.


Weight loss with The Thoman Tube Diet is immediate and noticeable. Some of our patients have lost up to 10% of their total body weight in 10 days. How much weight you will lose and how quickly you will lose it will be determined by how well you adhere to a calorie-free liquid diet while the feeding tube is in place. (You are allowed to drink water, black coffee and other calorie-free liquids.) Most of our patients have no problem sticking to the diet because the protein formula keeps them from feeling hungry.

After the feeding tube is removed, you can continue your weight loss by maintaining a low-calorie diet and exercising regularly. Our practice also offers educational weight-loss seminars so you can learn about long-term lifestyle changes that will help sustain your new look.
