Brief Summary:
The present study will assess the effects on glucose, ketones and other blood biomarkers fuels, cognition, quality of life, physical activity and well-being of a reduced carbohydrate menu (R-CHO) for 2 months in a population living in a residence for the elderly. This intervention study, identified as the SAGE project (phase 2), follows on from the Ketohome project (phase 1) assessing the feasibility of such a project.
Detailed Description:
Finding an effective therapeutic strategy for Alzheimer's disease (AD) is a societal priority, but it also remains a major challenge. With one exception in 2021, no new pharmaceutical treatment for AD has been approved for over 20 years. However, several clinical trials demonstrate the potential of ketogenic interventions to restore brain energy and improve cognition in people with mild cognitive impairment and AD. Recently, the largest and longest clinical trial of its kind shows that compensating for energy deficit in the brain during aging improves brain metabolic and cognitive functioning in people with early AD and could potentially delay AD.
One of the main types of ketogenic intervention is the highly reduced carbohydrate (5-10% of daily energy value compared to a normal value of 50-65%) and very high fat ketogenic diet. Despite the now well-established safety of the ketogenic diet and its therapeutic value in the treatment of epilepsy and type 2 diabetes, the latter remains difficult to implement in because of the compliance challenge. A reduced glycemic load diet where intake of refined carbohydrates and added sugar is restricted is found to be much less restrictive than a ketogenic diet. Phase 1 of this project showed that decreased carbohydrate (sugar) intake may improve long-term glycemic control and compliance compared to more severe carbohydrate restriction. Having better blood glucose control may also be important in decreasing the risk of AD possibly by improving the metabolic profile and/or by promoting the production and use of ketones. However, its effectiveness in helping cognition in the elderly is still unknown and any changes in dietary habits can be addressed with some resistance.
The objective of this project is therefore to answer the following question: does a reduction in carbohydrates of 30 to 50% for 2 months reduce the risk of AD by improving the metabolic profile in people living in a senior residence?
