Could a fasting byproduct be the key to metabolic gains?
NCT ID NCT07840807
First seen Sep 25, 2026 · Last updated Sep 25, 2026
Summary
Researchers at a Chinese hospital reviewed medical records of 1,149 adults with overweight, obesity, type 2 diabetes, or related metabolic conditions who had undergone a structured Traditional Chinese Medicine fasting therapy. The therapy lasts about nine days and combines severe calorie restriction with herbal formulas. The team checked whether rises in beta-hydroxybutyrate, a ketone the body makes during fasting, matched improvements in weight, waist size, blood pressure, blood sugar, and blood fats. No new tests or treatments were given; the study only analyzed existing data.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Traditional Chinese Medicine fasting therapy, a structured 9-day program combining calorie restriction with herbal formulas
- What this could lead to
- If a link holds between ketone rise and metabolic improvement, beta-hydroxybutyrate could become a marker doctors use to guide fasting-based treatment for obesity and type 2 diabetes.
- What could go wrong
- This study only reviews old records, so it cannot prove that fasting causes the improvements or that ketones drive them. Records may be incomplete, and the results may not apply to other fasting programs or patient groups.

Inclusion Criteria: * Male or female patients aged 18 years or older at the time of receiving TCM fasting therapy. * Diagnosed with overweight/obesity or a metabolism-related condition (e.g., overweight/obesity, metabolic syndrome, type 2 diabetes mellitus, dyslipidemia, or hypertension). * Received a structured Traditional Chinese Medicine (TCM) fasting therapy at The Seventh Affiliated Hospital, Sun Yat-sen University (Shenzhen). * Serum beta-hydroxybutyrate (βHB) levels were measured before and after TCM fasting therapy. * Availability of complete medical records containing baseline and post-therapy data on key metabolic indicators (body weight, BMI, waist circumference, blood pressure, lipid profile, and glycemic indices). Exclusion Criteria: * Patients with incomplete medical records lacking essential baseline or post-therapy metabolic data. * Patients with severe comorbidities that could independently affect metabolic outcomes (e.g., active malignancy, severe hepatic or renal insufficiency, or uncontrolled endocrine disorders other than the conditions being studied). * Patients who received other concurrent interventions that could significantly confound metabolic outcomes during the study period. * Pregnant or lactating women. * Patients whose medical records explicitly indicate refusal of data use for research purposes.
