Is it permissible for someone who cannot bear fasting due to extreme thinness, which increases with fasting and causes fatigue and health symptoms, to break their fast?

The fast of Ramadan is obligatory for every resident, healthy Muslim, and intentional breaking of the fast is a major sin. What was mentioned is not a permissible excuse for breaking the fast, and it is not permissible to break the fast except for illness or the fear of certain harm to the body or damage to an organ. One must fear Allah and be diligent in fasting, and weight gain can be achieved outside the days of Ramadan.
