Final answer:
Being below a healthy BMI range is not better and there are health risks for being underweight. Physical activity and a healthy diet can improve your BMI, but professional consultation is necessary if it's outside the healthy range.
Step-by-step explanation:
The statement 'There are no health risks for being underweight' is false. Being underweight can actually have numerous health risks. It can weaken the immune system, increase the risk of infections, lead to nutrient deficiencies, and negatively impact bone density. It is important to maintain a healthy BMI range for overall well-being.
Physical activity and a healthy diet can indeed help improve your BMI, but it is not the only factor. Factors such as genetics, metabolism, and underlying health conditions can also influence BMI. It is advisable to consult a health professional if your BMI is outside of the healthy range to understand the underlying causes and receive appropriate guidance.
