Stage 1 Obesity Diagnosis! Wigobi vs. Maunzaro?

A family member was diagnosed with Stage 1 obesity after a recent health checkup. Previously, they were in the pre-obesity stage, but their weight increased due to a lack of management. The reason they need to lose weight is that their knee joints are in very poor condition, and the doctor told them that weight loss is absolutely necessary. For Stage 1 obesity, which is more suitable: Wigobi or Maunza? Would it be better to get Maunza even if they are not morbidly obese? Or would Wigobi be okay?
