In Western countries age-related diets such as obesity and diabetes have become important risk factors for Alzheimer’s disease (AD). Anti-obesity drug discovery programmes have been ineffective with drug withdrawals due to adverse effects that were never predicted from clinical trials and drug development. These drugs have not reduced neurodegneration associated with obesity. Removal of drugs such as fenfluramine, phentermine, sibutamtramine and orlistat were not related to improvements in medical complications related to obesity. Cholesterol lowering drugs such as statins have not delayed the programmed cell death pathways in the brain with cholesterol and amyloid beta dyshomeostasis linked to neurodegeneration. Nutritional therapy instead of drug therapy has appeared as a novel approach by activation of nutrient sensing genes associated with appetite regulation with the delay in the diseases of the liver and brain that are connected to AD. High fibre diets that contain phytosterols and short chain fatty acids regulate hepatic membrane cholesterol and amyloid beta homeostasis with beneficial effects on glucose homeostasis and on cholesterol homeostasis. High fibre diets and their contents of bacterial lipopolysaccharides, mycotoxin and xenobiotics have become important with improvement in drug effectiveness related to the amount of fibre diet consumed associated with the intact peripheral amyloid beta clearance pathway and reversal of NAFLD. High fibre diets may improve anti-obese drug therapy in insulin resistance and AD and their reduced contents of LPS, mycotoxin and xenobiotics may improve interactions between drug molecules and membrane and nuclear receptors that elicit therapeutic effects in NAFLD and Alzheimer’s disease.
