He is a professor at the University of Southern California (USC) and director of the Longevity Institute. [1]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike many alternative practitioners, Longo is an established researcher who has dedicated decades to understanding aging and the cells\u2019 response to starvation. He is the inventor of FMD (Fasting Mimicking Diet) and the author of the book <em>The Longevity Diet<\/em>. He is known for having discovered the specific genes and signaling pathways (such as IGF-1) that control the aging of cells and resistance to stress.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">His work is not based on anecdotes, but on extensive clinical trials and basic research that has paved the way for a new understanding of the role of diet in cancer treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Cancers_Achilles_heel_Metabolic_rigidity\"><\/span>Cancer&#8217;s Achilles heel: Metabolic rigidity<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1280\" height=\"853\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol24.jpg\" alt=\"Valter Longo protokol symboliseret ved nogle r\u00f8d-orange celler og lysindfald p\u00e5 disse.\" class=\"wp-image-25863\" style=\"object-fit:cover;width:150px;height:150px\" srcset=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol24.jpg 1280w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol24-600x400.jpg 600w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol24-300x200.jpg 300w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol24-1024x682.jpg 1024w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol24-768x512.jpg 768w\" sizes=\"auto, (max-width: 1280px) 100vw, 1280px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">To understand why a diet can enhance chemotherapy, you must understand the difference between healthy cells and cancer cells. Longo exploits the phenomenon of \u201cDifferential Stress Resistance.\u201d<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Protection of the healthy<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">When the body lacks nutrients, healthy cells have an evolutionary mechanism: They shut down growth and use all energy for repair and protection. They build a shield around themselves, so to speak. This means that when chemotherapy hits, it bounces off the healthy cells because they are inactive.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Stress of the sick<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Cancer cells have lost this ability. Due to mutations (oncogenes), they are locked in a state of constant growth with &#8220;the accelerator pressed to the floor.&#8221; They cannot go into hibernation, even if there is no food.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When sugar and growth factors are removed (via the diet), a crisis arises in the cancer cell. It desperately tries to grow without fuel. If it is hit with chemotherapy in this state, it collapses much faster than usual. This is called \u201cDifferential Stress Sensitization.\u201d [2, 3]<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Lowering of IGF-1<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Research shows that high levels of the growth factor IGF-1 promote cancer. Longo\u2019s protocol effectively lowers IGF-1 levels dramatically within five days, thereby removing one of the tumor\u2019s most important growth signals.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_protocols_recipe_and_dosage\"><\/span>The protocol\u2019s recipe and dosage<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"806\" height=\"806\" src=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol13.jpg\" alt=\"Valter Longo protokol symboliseret ved en v\u00e6gt med noget pulver og en n\u00f8ddebar.\" class=\"wp-image-25860\" style=\"object-fit:cover;width:150px;height:150px\" srcset=\"https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol13.jpg 806w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol13-300x300.jpg 300w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol13-100x100.jpg 100w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol13-600x600.jpg 600w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol13-150x150.jpg 150w, https:\/\/jegharkraeft.dk\/wp-content\/uploads\/2025\/12\/Valter-Longo-protokol13-768x768.jpg 768w\" sizes=\"auto, (max-width: 806px) 100vw, 806px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The strategy is precise and requires adherence to macronutrients to work.
