Features:
5-day diet to mimic fasting without fasting.
FMDs are caloric-restricted plant–based diets containing low proteins, low sugar and high fats which represent a more feasible and safer option to water-only fasting.
Fasting modality                         Approx CRIS
--------------------------------------   ----------
Time-restricted eating (12–16 h)          –3 to –4
Early time-restricted eating (eTRE)        –4
Intermittent fasting (24 h 1–2x/week)     –4
Periodic fasting / FMD                    –4 to –5*
Calorie restriction (chronic)             –3 (risk tradeoffs)

Fasting-Mimicking Diet (FMD; ~5-day low-protein, low-calorie cycle) Cancer vs Normal Cell Effects
Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Insulin / IGF-1 signaling ↓ IGF-1 signaling (chronic stress) ↓ IGF-1 with regenerative priming Driver Sustained growth factor suppression Repeated IGF-1 lowering impairs tumor growth programs
2 AMPK → mTOR nutrient sensing ↓ mTOR; ↑ AMPK (growth inhibition) ↓ mTOR; ↑ AMPK (maintenance mode) Driver Prolonged anabolic suppression More sustained but less acute than STF
3 Autophagy / mitophagy ↑ autophagy → loss of tumor robustness ↑ autophagy → rejuvenation Driver Cellular renewal vs destabilization Repeated cycles promote organelle quality control
4 Mitochondrial metabolism ↓ metabolic resilience ↑ mitochondrial fitness Secondary Energy efficiency divergence Normal cells adapt better across cycles
5 Inflammatory signaling (NF-κB / cytokines) ↓ pro-tumor inflammation ↓ systemic inflammation Secondary Anti-inflammatory milieu Inflammation reduction contributes to chemopreventive effects
6 Reactive oxygen species (ROS) ↑ ROS (secondary, context-dependent) ↓ ROS Secondary Metabolism-linked redox shift ROS effects are indirect and less pronounced than STF
7 NRF2 antioxidant response ↔ modest activation ↑ NRF2 (protective) Adaptive Stress adaptation NRF2 supports normal-cell recovery between cycles
8 Cell cycle / regeneration ↓ proliferation ↑ regeneration post-cycle Phenotypic Degrowth vs regeneration FMD uniquely promotes regeneration upon refeeding

Type:
The selectivity of cancer products (such as chemotherapeutic agents, targeted therapies, immunotherapies, and novel cancer drugs) refers to their ability to affect cancer cells preferentially over normal, healthy cells. High selectivity is important because it can lead to better patient outcomes by reducing side effects and minimizing damage to normal tissues.

Achieving high selectivity in cancer treatment is crucial for improving patient outcomes. It relies on pinpointing molecular differences between cancerous and normal cells, designing drugs or delivery systems that exploit these differences, and overcoming intrinsic challenges like tumor heterogeneity and resistance

Factors that affect selectivity:
1. Ability of Cancer cells to preferentially absorb a product/drug
-EPR-enhanced permeability and retention of cancer cells
-nanoparticle formations/carriers may target cancer cells over normal cells
-Liposomal formations. Also negatively/positively charged affects absorbtion

2. Product/drug effect may be different for normal vs cancer cells
- hypoxia
- transition metal content levels (iron/copper) change probability of fenton reaction.
- pH levels
- antiOxidant levels and defense levels

3. Bio-availability
