The main aim of this clinical trial is to learn about the effect of carbohydrate-rich diet as a treatment for AIP (acute intermittent porphyria). Aim: Investigate the diet's impact on tissue and serum glucose, plasma insulin, cytokine levels, amino acids, and gut microbiota in AIP, and their correlation with PBG (Porphobilinogen). Aim: Assess the diet's effect on AIP symptoms and health status in AIP. Aim: Measure the effect of a high-carbohydrate diet on mitochondrial activity in AIP Aim: Map and detect potential mutations in mitochondrial genomic DNA in AIP Aim: Discover new markers in AIP through RNA sequencing and machine learning. Participants will follow two diet plans, a 4-week intervention with 60-65 E% carbohydrates and a 4 week intervention with 40-45 E% carbohydrates.
