Stress resistance has not been assessed however and so the biological relevance of this finding is currently unknown.32 Several IER trials (75 - 85 % ER
on restricted days) in overweight / obese populations have reported reductions in various markers of oxidative stress 37, 41, which in one study was accompanied by a complementary increase in the anti-oxidant uric acid.37 In a direct comparison of IER (75 % ER for two days / week) and CER, both ER strategies displayed equal efficacy in reducing levels of fast - acting advanced oxidation protein products (AOPP) after six months, which displayed a tendency to occur earlier (i.e. at three months) in the IER group.41 Levels of slow - acting (i.e. long term) AOPP tended to decrease in the IER group and increase in the CER group which the authors proposed may have resulted from IER - induced activation of autophagy, a key homeostatic cellular process in which dysfunctional or unnecessary cellular proteins are degraded and recycled.41 On the other hand, a follow - up study using similar IER / CER protocols demonstrated comparable reductions in AOPP in both groups after three months.48 Summary and Future Research Directio

autophagy related genes (ATG)
in animals is largely incompatible with life.
The point is that reducing insulin
on a regular basis slows some of that, and that IF, to the extent that it encourages or increases

in reducing the issues you describe.
