Healthy Weight: Guides & Advice

Healthy Weight

What you'll learn

Understanding a healthy weight

Measures such as BMI and waist circumference are useful screening tools, but they don't tell the whole story. We explain what they measure and their limitations.

Energy balance, explained

Weight change is influenced by the balance between the energy you eat and the energy you use — but also by sleep, stress, hormones, medications and genetics.

The role of physical activity

Regular activity supports weight management and brings benefits for the heart, mood and sleep that matter whatever the number on the scale.

Sleep, stress and appetite

Short sleep and chronic stress can affect hormones that regulate hunger, making it harder to manage weight. Looking after both is part of the picture.

Spotting fad diets

Plans that promise rapid results, ban entire food groups or rely on expensive products are rarely sustainable. We help you separate evidence from hype.

When to seek medical support

If you have health conditions, take regular medication or have struggled with weight for a long time, a doctor can discuss options and help you plan safely.
