Balanced Eating for Sustainable Weight Management
Diennet InstituteShare
Sustainable weight management without extreme dieting
Sustainable weight loss rarely comes from a quick fix. The aim is to build an eating pattern that is nutritious enough, suited to your health and daily life, and realistic to maintain over time.
Build satisfying meals
A simple structure can include vegetables or fruit, an appropriate source of protein, wholegrain or starchy foods according to individual needs, and mostly unsaturated fats. Portions and proportions should remain personalised.
Protein and muscle mass
Preserving muscle is particularly important during weight loss and after age 45. Protein needs vary with age, body size, activity, health status and overall energy intake. Resistance training can also help maintain strength and physical function.

Fibre and food quality
Vegetables, fruit, legumes and whole grains can support satiety and digestive health when well tolerated. Entire food groups do not need to be eliminated unless there is a specific reason to do so.
Avoid rapid-weight-loss promises
Body weight can fluctuate from week to week for many reasons, including fluid balance, salt intake, bowel habits and hormonal changes. A fixed rate of weight loss is therefore not a universal target.
After 45 and around menopause
Ageing, sleep, activity, muscle mass and menopause-related changes can interact. A sustainable approach considers the combination rather than attributing everything to a single factor.

When medical support may be appropriate
Clinical support can be useful when weight is associated with health conditions, medicines, symptoms or repeated unsuccessful attempts. Prescription treatments are not suitable for everyone and require individual assessment.
