Can cutting carbs curb metabolic syndrome in teens?
NCT ID NCT00940966
First seen Aug 21, 2026 ยท Last updated Aug 21, 2026
Summary
This pilot study tests whether two low-carbohydrate diets can improve metabolic syndrome in adolescents aged 13-18 who are obese. Participants will follow either a very-low-carb diet, a restricted ketogenic diet, or the standard American Diabetes Association diet. The goal is to see which approach better improves weight loss and key diabetes risk factors like blood sugar and triglycerides.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- low-carbohydrate diets (very-low-carb and restricted ketogenic) compared with the standard ADA diet
- What this could lead to
- If effective, these diets could offer a drug-free way to manage metabolic syndrome in teens, potentially reducing future risk of type 2 diabetes and heart disease.
- What could go wrong
- This is a small pilot study, so results may not be conclusive. Low-carb diets can be hard to stick to, and long-term effects in teens are not yet known.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adolescents and young adults ages 13-18 with a BMI\>95% for age or over 30 for young adults, with pre-existing metabolic syndrome Exclusion Criteria: * Subjects on any chronic medication other than antihistamines, asthma medications, oral contraceptives or diabetes medications, smoke more than 5 cigarettes/day, suffer from alcoholism or drug abuse or have any significant abnormality not associated with metabolic syndrome on screening labs will be excluded from randomization. * Subjects currently taking Byetta will be excluded from the study, as a side effect of the drug is weight loss. * Subjects with familial hypercholesteremia may be excluded if the investigator considers the history to be severe. The data collected from subjects with a HBA1C greater than 12.5 will be analyzed in a separate group, although they will still be randomized to one of the three treatment groups. This is due to the fact that past experience has shown that these individuals run a high risk of being non-compliant with medication use, diet, and exercise plans. Results from this group will be reported separately. * Subjects who are pregnant or those desiring pregnancy will be excluded, as the safety of this intervention in pregnancy has not been established.
