Evidence check: WeightLoss Slim DNA in the context of fertility

The MyBody-X WeightLoss SLIM DNA test analyzes SNPs like FTO and MC4R that have small effects on metabolism. Evidence for weight loss is human-moderate (observational/GWAS), not strong RCTs. In the context of fertility, the evidence is even weaker: while obesity impairs fertility, the test only predicts a genetic tendency, not a specific fertility disorder. Other factors like hormonal status, diet, and lifestyle are far more important. This test should not be used as a sole basis for fertility decisions. Safety note: always seek medical evaluation for unresolved infertility.
