The GLP Diet is a nutrition programme built around GLP-1 – the gut hormone that controls appetite, fullness and blood-sugar response. It has two uses: supporting people who are on prescribed GLP-1 weight-loss medications (such as semaglutide or tirzepatide), and helping others eat in a way that naturally supports their own GLP-1 and satiety response.
For those on the medication, the diet protects against the common pitfalls of rapid weight loss – muscle loss, poor protein and nutrient intake, and side effects like nausea – by prioritising protein, fibre, hydration and nutrient density. These medications are prescribed and monitored by a physician; this programme supports them and does not replace them.
Frequently Asked Questions
How does it support GLP-1 medication?
Appetite drops sharply on these medicines, so the plan makes every meal count – enough protein to preserve muscle, fibre for fullness and gut health, hydration, and practical strategies for nausea and small appetite, plus nutrient checks to prevent deficiencies.
Can it help if I am not on the medication?
Yes – certain eating patterns (adequate protein, fibre, whole foods and meal structure) support your own GLP-1 and satiety response, which can help appetite control and weight management naturally.
Does this replace the weight-loss injection?
No. If you are on a GLP-1 medication, it is prescribed and monitored by your doctor; this diet works alongside it to make the results healthier and more sustainable and to reduce muscle loss.
Who should avoid it?
It is individualised; those on the medication should be under medical supervision, and it is not suitable in pregnancy or for anyone with a history of an eating disorder without specialist input.
Why focus so much on protein?
Rapid appetite suppression can cause significant muscle loss along with fat loss; keeping protein high, with resistance activity, protects muscle and metabolism during weight loss.
