Overview
- The RTL presenter posted an Instagram photo on January 2 showing a defined midsection and said he is about ten kilograms lighter, calling himself proud of the progress.
- He traced the change to healthier eating, regular cycling since spring 2025, and a gradual return to running, starting with 15-minute treadmill sessions due to a previously operated knee.
- Köppen emphasized feeling good over chasing numbers and advised avoiding strict food bans, setting modest goals, and removing pressure for sustainable progress.
- He noted a difficult December that included three days in the hospital over Christmas for a persistent cough and a planned spleen surgery for his dog during which the animal suffered cardiac arrest.
- Köppen is slated to reunite with Sonja Zietlow to host Ich bin ein Star – Holt mich hier raus! on RTL starting January 23, with daily broadcasts also available on RTL+.
