Study Arms:
- ruminant TFA (Type: ACTIVE_COMPARATOR): In addition to the basic diet, volunteers enrich their diet with an individually calculated amount of butter containing ruminant TFA and with 15-20g rape oil for balancing the essential fatty acids.
- industrial TFA (Type: ACTIVE_COMPARATOR): In addition to the basic diet, volunteers enrich their diet with an individually calculated amount of butter containing TFA from PHVO and with 15-20g rape oil for balancing the essential fatty acids.
- without TFA (Type: PLACEBO_COMPARATOR): In addition to the basic diet, volunteers enrich their diet with an individually calculated amount of butter without TFA and with 15-20g rape oil for balancing the essential fatty acids.

Based on this trial design, predict the completion outcome and termination type (if applicable).
