What is a healthy weight?
You can find out whether your weight is within the healthy range by calculating your body mass index or BMI. Check your BMI using our BMI chart.
For many people, it’s just not realistic to aim for a so-called “ideal weight” for your height. Instead of focusing on a target weight, it may be more helpful to work on changing your lifestyle, which can help you reach a healthier weight.
Small changes can have big effects
Most people gain weight throughout their lives, often without realizing it. Very small changes can result in large weight gains over time, For example by simply eating an excess of 50 calories per day – just half a biscuit – you could gain 5 pounds or 2kg over a year. So in 5 years’ time you could be over 25 pounds or 10 kg heavier.
But good news is that small changes of your lifestyle can lead reduction in body weight. This may sound simple, but in reality it takes commitment and effort to change the habits of a lifetime. The day-to-day choices we make about our lifestyle have the greatest effect on our weight.
