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 .
Impact of weight loss diet associated with flaxseed on inflammatory markers in men with cardiovascular risk factors: a clinical study
Background Flaxseed has received attention for its anti-inflammatory and antioxidant role . The present study hypothesizes if flaxseed added to a weight loss diet could improve the lipid and metabolic profiles and decrease risk factors related to cardiovascular disease . Methods In a prospect i ve , single blinded 42 days protocol , subjects were allocated into two groups with low carbohydrates intake : GriceLC ( 35 % of carbohydrate and 60 g of raw rice powder per day ) and GflaxLC ( 32 % of carbohydrate and 60 g of flaxseed powder per day ) . Blood pressure , anthropometric measures and serum levels of isoprostane , C-reactive protein , Tumor Necrosis Factor-alpha , glucose , lipidic profile , uric acid , adiponectin , leptin and insulin were measured at baseline and at the end of interventions . Serum and urinary enterodiol and enterolactione were also measured . Results A total of 27 men with cardiovascular risk factors were evaluated , with mean age of 33 ± 10 years to GriceLC and 40 ± 9 years to GflaxLC . Both groups experienced weight loss and systolic blood pressure reduction . A decrease in inflammatory markers ( CRP and TNF-α ) was observed after flaxseed intake ( mean decrease of 25 % and 46 % for GflaxLC respectively ) . All groups also showed improvement in levels of total cholesterol , LDL-c , uric acid and adiponectin . Only GflaxLC group showed a decrease in triglyceride levels . Conclusion This study suggests that flaxseed added to a weight loss diet could be an important nutritional strategy to reduce inflammation markers such as CRP and TNF-α .
