Macro partitioning
Spirulina supplementation does NOT significantly preserve skeletal muscle mass (SMM) during gradual weight loss compared to placebo; both groups lost similar amounts of muscle mass.
Do not rely on spirulina to preserve your muscle mass during a weight cut. This study showed that wrestlers taking spirulina lost the same amount of muscle as those taking a placebo. To preserve muscle, you must ensure your overall protein intake is high (1.6-3.1 g/kg/day) in addition to following your gradual weight loss diet.
GoodRefutesHIGH confidence
no significant between-group differences were noted (P = 0·673) when we compared changes from pre-test to post-test [SMM]... Interestingly, it was observed that the reduction in BFP and FM was greater after SP.
Why this rating
RCT design, clear statistical result showing no difference in SMM between groups.
