In metabolic syndrome, resistance training was the exercise linked to lower fasting glucose
In short
In a network meta-analysis of 78 randomized trials covering 8,452 adults with metabolic syndrome and overweight or obesity, all four structured exercise-only interventions were associated with lower systolic and diastolic blood pressure than control, and resistance training was associated with lower fasting blood glucose. A simple model adding the effects of exercise and diet fit only waist circumference and triglycerides, not the other four outcomes. Certainty was low to very low for most comparisons.
Walking and cardio are the usual first advice for metabolic syndrome. Yet in a network meta-analysis of 78 randomized trials with 8,452 participants published through December 2025, the exercise-only intervention associated with lower fasting glucose was resistance training. Blood pressure, meanwhile, came out lower with all four exercise types.
What was compared?
Participants were adults with metabolic syndrome plus overweight or obesity. The authors compared exercise only, diet only and combined exercise and diet against inactive or minimal-intervention controls and against each other. Outcomes were the six components that define metabolic syndrome: waist circumference, systolic and diastolic blood pressure, fasting glucose, triglycerides and HDL cholesterol.
What differed by exercise type and diet combination?
- All four exercise-only approaches — associated with lower systolic and diastolic blood pressure than control.
- Resistance training — associated with lower fasting glucose.
- Exercise plus a Mediterranean diet — associated with smaller waist circumference.
- Moderate continuous cardio plus calorie restriction — associated with lower triglycerides.
- Moderate continuous cardio plus a low-carb diet — associated with lower fasting glucose.
The authors also tested whether the combined results equal the exercise effect plus the diet effect. That simple addition fit only waist circumference and triglycerides. For blood pressure, fasting glucose and HDL, doing both did not stack up so neatly.
What does this mean if you lift?
If blood sugar is a concern, resistance training is not just a stand-in for cardio — it has its own reason to be in your week. Training the big three already puts you in the exercise type linked to the glucose benefit, while waist size and triglycerides moved more when diet changed too. How weekly exercise volume relates to insulin resistance markers is covered in this article. Logging waist measurements or checkup numbers alongside your training makes it easier to see what is changing for you.
Certainty was low to very low for most comparisons, and the authors did not name a best approach. If you take blood pressure or diabetes medication, talk to your doctor before making big changes to training or diet.
Frequently asked questions
Does resistance training help metabolic syndrome?
In a network meta-analysis of 78 randomized trials and 8,452 people, resistance training was associated with lower fasting glucose than control, and like other exercise types with lower systolic and diastolic blood pressure. Certainty was mostly low to very low.
Which exercise lowers blood pressure in metabolic syndrome?
In this analysis, all four structured exercise-only approaches were associated with lower systolic and diastolic blood pressure than control. The benefit was not limited to one exercise type.
Does combining diet and exercise double the benefit?
It depends on the measure. A model simply adding exercise and diet effects fit only waist circumference and triglycerides, not blood pressure, fasting glucose or HDL cholesterol.
What is the best exercise and diet combination for metabolic syndrome?
The analysis did not name one. Exercise plus a Mediterranean diet was linked to smaller waists, moderate cardio plus calorie restriction to lower triglycerides, and moderate cardio plus a low-carb diet to lower fasting glucose, but the authors framed these as candidates for direct head-to-head trials.
