This study focused on seven studies selected for evidence evaluation (three were conducted in the U.S., two in Denmark one in the U.K. and one study in Australia). The total number of participants was 2,854. The dietary intervention programs offered to the participants were rather diverse. All interventions were long-term programs that reinforced maintaining stable calorie intake and the balanced nutritional intake. These studies showed couple same results:

  • On the weight: Six studies demonstrated a significant weight loss effect. The meta-analysis showed that the weight decreased by −4.37 kg (95% CI: −6.54 to −2.20) , which was statistically significant (Z = 3.95, P < 0.001).
  • On the BMI (Body Mass Index): Six studies demonstrated changes in BMI. The meta-analysis showed that the BMI decreased by −1.26 kg/m2 (95% CI: −1.98 to −0.55), which was also statistically significant (Z = 3.47, P = 0.0005).
