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 Directions

The negative effects seem to lie in the capacity of some foods / nutrients to stimulate proliferative pathways that in turn stimulate development of acne — suspect foods include those with a high glycaemic load and milk.11, 43, 44 Other evidence comes from several studies reporting that the prevalence of acne varies significantly between different populations and is substantially lower in non-Westernized populations that follow traditional diets, 45 a common factor among these traditional diets being a low glycaemic load.46 Various studies have provided evidence that high - glycaemic - load diets are implicated in the aetiology of acne through their capacity to stimulate insulin, androgen bioavailability and insulin - like growth factor - 1 (IGF - 1) activity, whereas the beneficial effects of low - glycaemic - load diets, apart from weight and blood glucose levels, also include improved skin quality.44 The clinical and experimental evidence does in fact suggest ways in which insulin can increase androgen production and affect via induction of steroidogenic enzymes, 47 the secretion by the pituitary gland of gonadotropin - releasing hormone and the production of sex hormone - binding globulin.48 Insulin is also able to reduce serum levels of IGF - binding protein - 1 increasing the effect of IGF - 1.49 These insulin - mediated actions can therefore influence diverse factors that underlie the development of acne such as:
