GLP‑1, Hunger and Metabolism: A Guide to Satiety and Weight Management
Understanding Hunger, Satiety and Metabolism
Why do some meals keep us feeling full for longer? What is GLP-1, and how does it relate to diet, the gut microbiome and weight regulation?
This guide takes you through twelve articles: from hunger hormones, protein and fibre to exercise, weight loss after forty and maintaining results. For the substances under investigation, we distinguish biological mechanisms, findings in humans and the limits of the available evidence.
Where should you start?
If you are new to the topic, start with article 01 on hunger and satiety hormones. If you are interested in a specific area, select it directly from the menu. Each article includes explanations, sources and answers to frequently asked questions.
What should you take away from this guide?
Weight regulation cannot be explained by a single hormone or plant-derived substance. As you read the series, distinguish three things: what happens in a biological experiment, what was measured in humans and whether the finding actually translated into long-term weight change.
An interesting mechanism does not promise an effect. Findings for a particular extract or medicine cannot automatically be applied to another preparation. This guide helps you navigate and understand research; it is not intended for choosing treatment or self-diagnosis.
Frequently Asked Questions About the Guide
Where can I find an explanation of GLP-1 and other hormones?
Start with article 01. It compares GLP-1, GIP, ghrelin, leptin and insulin and explains their different roles.
Which articles cover diet and the gut?
Article 02 examines studies on protein and fibre. Article 03 follows with the gut microbiome and short-chain fatty acids, known as SCFAs.
Does the guide also cover berberine, chromium and L-carnitine?
Yes. Article 04 covers berberine, while article 05 discusses chromium and L-carnitine. Article 10 examines gymnema, green tea and garcinia, including research limitations and safety questions.
Are natural GLP-1 and medicines the same?
Natural hormonal responses, the effects of foods and medical treatment should not automatically be treated as interchangeable. Article 06 explains the differences between these areas.
What should I read about weight loss after forty or weight regain?
Article 11 covers muscle, hormonal changes and energy needs in middle age. Article 12 explains adaptation after weight loss and maintaining results over time. Articles 07 and 08 provide further context on sleep, stress and exercise.
Does this series recommend taking supplements or changing treatment?
No. These are educational articles without recommendations for specific products. Discuss diagnosis, whether weight loss is appropriate and any treatment changes individually with a healthcare professional.
Simply put
Hunger and fullness are influenced by hormones, food, sleep, stress and exercise. GLP-1 is one of these signals. This series explains how they relate to each other and why research findings for an ingredient cannot automatically be applied to a particular supplement.
