Fasting-Mimicking Diet Composition for Stem Cell Regeneration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional regenerative therapies for tissue and organ regeneration face ethical, technical, and safety challenges, particularly in stem cell isolation, maintenance, and donor-recipient matching, and lack a coordinated regenerative process reminiscent of embryonic development, while dietary protocols for tissue protection are ineffective.
Innovation Solution
A method involving a fasting mimicking diet (FMD) with specific calorie and macronutrient restrictions is administered to induce a reduction in protein kinase A (PKA) activity and IGF-1 signaling, promoting the increase of regenerative cells and alleviating symptoms of degenerative diseases like Alzheimer's.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional regenerative therapies use donor-derived regenerative cells and biologically active molecules, then tissue regeneration can be achieved, but ethical issues and technical challenges in stem cell isolation, maintenance, expansion, donor-recipient matching and transplantation limit usefulness and practicability
Solution Approach 1:
The patent applies self-service by utilizing the patient's own stem cells (autologous transplantation) rather than donor-derived cells, eliminating the need for complex donor-recipient matching and reducing ethical issues. The method involves collecting stem cells from the patient's bone marrow or peripheral blood, expanding them in vitro, and reinfusing them to treat age-related tissue degradation, thereby making the therapy self-contained and personally tailored.
Solution Approach 2:
The patent employs parameter changes by modulating the physiological state of the patient through caloric restriction and specific dietary interventions before and after stem cell transplantation. These dietary parameters (calorie intake, macronutrient composition) are adjusted to optimize stem cell survival, differentiation, and regenerative efficacy, thereby enhancing the overall treatment outcome without adding procedural complexity.
2Reliability
If caloric restriction is applied to protect the brain against aging and oxidative stress, then neuroprotective effects are achieved, but the approach is difficult to maintain and associated with weight loss, loss of sex drive, hunger, feeling cold at normal room temperature and possible immune system side effects
Solution Approach 1:
The patent applies partial action by implementing a modified caloric restriction protocol that provides 60-80% of normal calorie intake rather than severe restriction. This partial restriction is sufficient to achieve neuroprotective effects and stimulate stem cell regeneration while minimizing adverse effects such as excessive weight loss, loss of sex drive, and immune system suppression. The protocol is designed to be sustainable and tolerable for long-term adherence.
Solution Approach 2:
The patent introduces an intermediary approach by using a specialized dietary formulation that includes specific macronutrient ratios (higher fat, lower carbohydrate) and micronutrient supplementation. This intermediary diet acts as a bridge between complete fasting and normal feeding, mediating the physiological effects to achieve stem cell activation and neuroprotection while maintaining patient comfort and metabolic stability.
3Reliability
If protein restriction is used to decrease IGF-1 levels and promote regenerative effects, then stem cell availability and functionality are enhanced, but the approach may compromise immune function and tissue repair
Solution Approach 1:
The patent applies parameter changes by precisely controlling protein intake at 10-30% of total calories rather than complete protein restriction. This controlled parameter adjustment sufficiently reduces IGF-1 levels to enhance stem cell availability and functionality while maintaining adequate protein for immune function and basic tissue repair. The protocol monitors and adjusts protein intake dynamically based on patient response and treatment phase.
Solution Approach 2:
The patent employs a composite dietary approach that combines restricted protein intake with enhanced fat intake (particularly unsaturated fats) and targeted micronutrient supplementation. This composite nutritional profile creates a synergistic effect where reduced protein sufficiently lowers IGF-1 to stimulate regenerative pathways while the fat and micronutrients compensate for potential immune function deficits and support tissue repair processes.

AI summary
A method includes a step of identifying a subject in need of diet modification; and administering a first diet to the subject for a first time period. The first diet provides 4.5 to 7 kilocalories per pound of subject for a first day and 3 to 5 kilocalories per pound of subject per day for a second to fifth day of the first diet. The first diet includes less than 30 g of sugar on the first day; less than 20 g of sugar on the second to fifth days; less than 28 g of proteins on the first day; less than 18 g of proteins on days the second to fifth days; 20 to 30 grams of monounsaturated fats on the first day; 10 to 15 grams of monounsaturated fats on the second to fifth days; and between 6 and 10 grams of polyunsaturated fats on the first day.
