3.2 Anthropometric indices and nutrients intake
Between group analysis were non-significant for the body weight, BMI
(Table 2), energy, macro-and micronutrients intake at baseline (Table
3). Weight and BMI showed a statistically significant reduction in
intervention group at the end of the trial, compared to placebo group
(Table 2, P< 0·05) after adjusting for confounding factors
(sex, PAL, energy intake and baseline). Within group analysis showed
that there was a non-significant reduction of body weight and BMI in the
placebo group, whereas it was significant in the intervention group
(paired T-test, P< 0·05). The mean of antioxidant
micronutrients intake was not different between placebo and intervention
groups. The dietary intake of macronutrients and energy were
significantly changed at the end of the intervention (except for protein
and fiber intake) in the intervention group compared to placebo group
(ANCOVA, P<0·05). Also, the intake of energy and
macronutrients (carbohydrate, protein, total fat and fiber) was
significantly different in the intervention and placebo groups after 12
weeks intervention compared with baseline (paired Student t-test, P
< 0.05).
