This is why she 'weeded out' her friends - Daniela Katzenberger's 22-pound weight loss sparks debate and personal rifts

Daniela Katzenberger has undergone a dramatic transformation, shedding over 22 pounds through rigorous fitness and dieting. The reality TV star has now distanced herself from critics of her new lifestyle and fitness focus in the USA. Her journey has been detailed in her 2026 book, Katze goes Muskelkater.

Katzenberger's weight loss has sparked mixed reactions. While she feels more confident, some fans and friends have openly missed her previous appearance, calling her dedication a 'fitness obsession'. Even her husband, Lucas Cordalis, admitted he wishes she would regain some weight—though he supports her self-assurance.

The intense training for bodybuilding competitions has taken a toll. Katzenberger has described the preparation as gruelling, and the strain has affected her relationship with Cordalis. Despite this, she remains determined, with plans to enter another tournament this autumn.

Her shift in priorities has also led to changes in her personal life. Frustrated by a lack of encouragement, she has cut ties with people in her inner circle who do not back her new direction. The transformation, however, has not visibly altered her TV career or hosting roles so far.

Katzenberger's focus remains on fitness, with another competition on the horizon. Her book documents the highs and challenges of her career advice journey, while her personal relationships adapt to the changes. The long-term impact on her career and public image is still unfolding.
