Summary

This study evaluated the SWW Method®, a 12-week dietary and lifestyle intervention based on the carbohydrate-insulin model, in a healthy cohort of women aged 35-75. The study assessed whether the intervention resulted in significant improvements in blood glucose markers (HbA1c, fasting blood glucose), weight, BMI, and other metabolic markers compared to a no-intervention control group. The SWW Method® protocol includes intermittent fasting, a protein-forward diet, meal sequencing, hydration, magnesium supplementation, and sleep support. This was a non-randomized case-control trial with 45 intervention participants and 40 controls, conducted over 12 weeks.

Detailed description

The SWW Method® study is a non-randomized case-control trial in which participants self-selected into either the SWW Method® intervention group (cases) or a no-intervention control group through separate recruitment channels. Primary, secondary, and exploratory outcome measures were compared between the two groups. This 12-week trial was designed to evaluate the SWW Method®'s effect on blood sugar balance and weight loss in a moderately healthy population of women aged 35-75. Cases completed the six-week SWW Method® program, followed by six weeks of coach-supported accountability via the ATE™ app. Questionnaires and lab work were collected one week before and six weeks after the intervention to assess changes over the 12-week period. The SWW Method® is an isocaloric carbohydrate-insulin model (CIM)-based protocol designed to support blood sugar balance and weight loss through: adequate hydration, alkalizing with a daily greens powder, intermittent fasting, conscious meal timing, a protein-forward diet, non-starchy vegetables with every meal, limiting starchy carbohydrate intake to once per day, magnesium supplementation, and optimizing circadian rhythm. The protocol is delivered through nutrition education, group coaching, and one-on-one nutrition support. Participants completed a Comprehensive Health Profile through Quest Diagnostics at baseline and 12 weeks, including a complete blood count (CBC), comprehensive metabolic panel (CMP), lipid/cholesterol panel, urinalysis, hemoglobin A1c (HbA1c), vitamin D, and high-sensitivity C-reactive protein (hsCRP), as well as biometrics including height, weight, waist circumference, and blood pressure. The primary outcome was change in HbA1c / fasting blood glucose and weight / BMI between baseline and 12 weeks. Secondary outcomes included changes in lipid markers, blood pressure, C-reactive protein, and other lab and biometric measures. Statistical analysis was performed using the Wilcoxon signed-rank test for within-group comparisons and difference-in-differences regression for between-group comparisons.
