Subgroup analyses showed that using whole flaxseed in doses ≥30 g d-1 , longer-term interventions ( ≥12 weeks ) and studies including participants with higher BMI ( ≥ 27 kg m-2 ) had positive effects on body composition  .
Whole flaxseed is a good choice for weight management particularly for weight reduction in overweight and obese participants
Flaxseed consumption may be inversely associated with obesity ; however , findings of available r and omized controlled trials ( RCTs ) are conflicting .
The present study aim ed to systematic ally review and analyse RCTs assessing the effects of flaxseed consumption on body weight and body composition .
Effect of high-oleic canola and flaxseed oils on energy expenditure and body composition in hypercholesterolemic subjects.
OBJECTIVE The fatty acid profile of dietary fats may contribute to its channelling toward oxidation versus storage , influencing energy and weight balance . Our objective was to compare the effects of diets enriched with high-oleic canola oil ( HOCO ) , alone or blended with flaxseed oil ( FXCO ) , on energy expenditure , substrate utilization , and body composition versus a typical Western diet ( WD ) . MATERIAL S/ METHODS Using a r and omized crossover design , 34 hypercholesterolemic subjects ( n=22 females ) consumed 3 controlled diets for 28 days containing ~49 % energy from carbohydrate , 14 % energy from protein , and 37 % energy from fat , of which 70 % of fat was provided by HOCO rich in oleic acid , FXCO rich in alpha-linolenic acid , or WD rich in saturated fat . Indirect calorimetry measured energy expenditure and substrate oxidation . Body composition was analyzed by dual-energy x-ray absorptiometry . RESULT After 28 days , resting and postpr and ial energy expenditure and substrate oxidation were not different after consumption of the HOCO or FXCO diets compared with a typical Western diet . No significant changes in body composition measures were observed between diets . However , the and roid-to-gynoid ratio tended to increase ( P=.055 ) after the FXCO diet compared with the HOCO diet . CONCLUSIONS The data suggest that substituting a typical Western dietary fatty acid profile with HOCO or FXCO does not significantly modulate energy expenditure , substrate oxidation or body composition in hypercholesterolemic males and females
