The Perfect Storm - Five Low Pressure Systems

The Perfect Storm – Five Low Pressure Systems

A picture is worth a thousand words.  As this diagram astutely shows, decreases in exercise, fiber, polyphenols, O3/O6 intake and tissue ratios, and caloric restriction all lead to the metabolic syndrome (abdominal obesity, dyslipidemia, hypertension, and a chronic inflammatory and prothrombotic state), chronic disease, and early death.

Calorie Restriction, Fasting, and Exercise

Dietary, Behavioral, and Pharmacologic Inputs Converge on cAMP-AMPK-SIRT1 Signaling to Produce Metabolic Benefits


Resveratrol inhibits PDEs, leading to increased cAMP levels, Epac1 activation, elevated intracellular calcium, and AMPK activation. Calorie restriction and other behavioral inputs also activate AMPK. Downstream of AMPK, an increase in NAD+levels leads to SIRT1 activation, which promotes beneficial metabolic changes primarily through deacetylation and activation of PGC-1α. In a parallel pathway, increased cAMP levels activate PKA, which directly phosphorylates and activates SIRT1. SIRT1 activation by either pathway, as well as potential activation of other NAD+-dependent enzymes, can lead to numerous physiologic outputs. Blue box (top) highlights findings reported by Park et al. (2012); orange box (bottom) highlights pathway components previously identified that reside downstream of those identified by Park et al., as well as some of the reported and theoretical outputs of the signaling pathways detailed above. Blue arrows indicate the linear pathway proposed by Park et al.; dashed lines indicate molecular connections previously reported. PDE, phosphodiesterase; cAMP, cyclic AMP; Epac1, cAMP-regulated guanine nucleotide exchange factor 1; CamKKβ, calcium/calmodulin-dependent kinase kinase beta; AMPK, AMP-activated protein kinase; PKA, protein kinase A; NAD+, nicotinamide adenine dinucleotide; PGC-1α, peroxisome proliferator-activated receptor gamma coactivator-1 alpha; ROS, reactive oxygen species.Vitality Strategies

Mechanisms modulating oxidant/antioxidant balance in obesity. On the left-hand side are shown mechanisms underlying oxidative stress in obesity and obesity-associated complications, while on the right-hand side are shown strategies improving body antioxidant machinery (see text for details). Dotted lines: inhibitory effect. Solid lines: stimulatory effect.

The diagrams above outline how all of the concepts we preach cause favorable biochemical and epigenetic changes that reduce disease, increase longevity and vitality, and optimize health.
We all know what to do. All we have to do is get up off the couch and do it!
