Chronic stress may be the hidden reason why weight refuses to drop even when a person eats well and exercises regularly, according to the German physician Daniela Kielkowski. She has developed a 30-day plan aimed at breaking what she describes as a vicious cycle in which sustained psychological pressure undermines the body's ability to shed pounds.
Kielkowski's argument places stress at the centre of unexplained weight stagnation. In her view, the problem is not always a lack of discipline or a failure to follow dietary rules. Persistent stress can act as a silent obstacle, keeping the body from responding to healthy habits in the way patients expect. Her proposed 30-day programme is designed to interrupt that pattern rather than simply intensify dieting.
The Belgian endocrinologist and obesity expert Bart Van der Schueren, of UZ Leuven, has examined Kielkowski's theory and offers a more measured assessment. While he does not dismiss stress as a relevant factor, he points to other influences that can explain why weight loss stalls. His response suggests that stress is part of a broader picture rather than the single cause.
Van der Schueren also warns that dieting can be taken too far. In his view, an overly strict approach may itself become counterproductive, adding another layer of pressure rather than solving the underlying problem. The observation echoes Kielkowski's concern that rigid regimens can backfire, though the two specialists frame the issue differently.
The debate touches on a question familiar to many people who monitor their food intake and physical activity without seeing the results they expect. Kielkowski's contribution is to name chronic stress as a distinct and often overlooked driver. Van der Schueren's contribution is to keep the focus on the complexity of obesity and metabolism, where no single explanation fits every case.
For patients, the practical implication is that unexplained weight stagnation may deserve a broader conversation with a doctor. Stress, the strictness of a diet, and other medical factors can all play a role. Neither specialist offers a universal solution, but both suggest that simply trying harder at the same approach is not always the answer.
The discussion reflects a wider shift in how clinicians think about weight. Rather than treating it as a matter of willpower alone, the focus increasingly falls on the interaction between behaviour, biology and the pressures of daily life. Kielkowski's 30-day plan and Van der Schueren's caution both belong to that evolving conversation.
