Intermittent fasting with calorie restriction and exercise for adults with metabolic syndrome
Official title: The Effectiveness of Intermittent Fasting, Caloric Restriction and Physical Activity Intervention On Metabolic Syndrome Biomarkers Among Adults With Metabolic Syndrome at Hospitals in Riyadh, Saudi Arabia
Run by Universiti Putra Malaysia · NCT07181655 · Data updated 2026-11-12
This program will test whether combining intermittent fasting, reduced calories, and increased physical activity helps adults with metabolic syndrome improve blood sugar, blood pressure, cholesterol, and weight.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older who meet criteria for metabolic syndrome (three or more of abdominal obesity, high triglycerides, low HDL, elevated blood pressure, or elevated fasting glucose) and who can attend clinic visits are ideal candidates.
✕Probably not a fit
People who are pregnant or lactating, have severe heart, kidney, or liver disease, recent bariatric surgery, major cognitive or physical disabilities, or who use insulin or certain oral antidiabetic drugs are excluded and unlikely to benefit from this protocol.

What this trial studies
This randomized controlled trial will assign 140 adults with metabolic syndrome to either a modified intermittent fasting program combining caloric restriction and promoted physical activity or to standard hospital care. Participants will be followed before and after the intervention to measure changes in glycemic control (fasting glucose, HbA1c), blood pressure, lipid profile, weight, BMI, and waist circumference, as well as physical activity, sleep quality, and dietary intake. The intervention arm uses a combined behavioral approach (timed eating with calorie targets plus increased physical activity) while the control arm receives usual care. Outcomes will be compared between groups to determine whether the combined lifestyle approach produces greater improvements in metabolic syndrome biomarkers and body composition.
Why it matters
Potential benefit: If successful, the program could help people with metabolic syndrome lower blood sugar and cardiovascular risk factors and lose weight through achievable lifestyle changes.
How similar studies have gone: Prior research has shown that intermittent fasting, caloric restriction, and increased physical activity can improve metabolic markers individually and in combination, though results vary by population and intervention design.
