A Government of Canada survey in 2018 revealed that 63% of Canadians are at risk of health problems due to obesity. One way to determine your healthy weight is by calculating your Body Mass Index (BMI). Divide your weight (in kilograms) by your height (in metres squared). A BMI between 18.5 kg/m. sq. and 24.9 kg/m. sq. is considered healthy. Above or below this range is overweight or underweight. Consult a dietitian about healthy eating habits and get enough physical activity to maintain a healthy weight.
