Warum dein Stoffwechsel das Abnehmen blockiert | NANO Doku

Counting calories, exercising, eating a balanced diet – and yet millions of people struggle with being overweight. Others seem to be able to eat whatever they want and stay slim. But why? New research shows that our metabolism plays a much larger role than previously thought. Controlled by the brain, influenced by hormones, and surprisingly active fat, it can become unbalanced. Endocrinologist Tim Hollstein from the Helmholtz Institute in Leipzig is researching why metabolism varies so much from person to person. One important finding: Some people burn energy particularly efficiently, thanks to active brown fat, which produces heat instead of fat storage. Stephanie Kullmann from the Helmholtz Institute in Tübingen has discovered that an unhealthy diet disrupts insulin sensitivity in the brain – long before the scales show excess weight. The hormone insulin not only acts in the body but also as a pacemaker for the entire metabolism – directly in our brain. The NANO documentary shows how scientists are investigating different metabolic types and, thanks to state-of-the-art technology, can provide individualized recommendations. #WeightLoss #Brain #Documentary #Metabolism #Nutrition #Overweight NANO – the science magazine on 3sat More NANO at: https://kurz.3sat.de/FLG/ Even more exciting science documentaries: https://kurz.3sat.de/PjM/ 00:02 – Freezing for Science Tim tests how cold affects metabolism. 01:00 – Two Metabolic Types Pia can hardly lose weight, Natalie can hardly gain weight – why? 03:22 – What Determines Our Metabolism Nutrition, stress, genes, hormones – a complex interplay. 04:36 – The Kiel Study Comparison between "efficient" and "wasteful" metabolism. 07:19 – FGF21: The Key Hormone How a liver hormone boosts energy consumption. 10:47 – Test in the Metabolic Chamber Direct comparison of energy consumption and respiratory gases. 14:50 – Energy Consumption & Brown Fat Why just a few grams of brown fat make all the difference. 19:17 – How to Boost Your Metabolism Exercise, fasting, cold exposure, chili – small stimuli with a big impact. 25:50 – Daniel Tests His Insulin Response How nutrition blocks or unlocks fat metabolism. 40:20 – Successes and New Perspectives Measurable progress and insights for the future.
