PGC-1α coactivates all three known PPAR isoforms (PPARα, PPARδ, and PPARγ) . Although each isoform is expressed in a variety of tissues, PPARα is prominently expressed in the liver, PPARδ in skeletal muscle, the heart, and the pancreas, and PPARγ in adipose [286, 296]. PGC-1α was discovered and named based on its promotion of brown adipose differentiation through coactivation of PPARγ and subsequent induction of mitochondrial biogenesis and UCP1 expression . However, it is the PGC-1α coactivation of PPARα that is responsible for the upregulated transcription of many of the enzymes responsible for increased ketogenesis and fatty acid metabolism in response to a ketogenic diet . Consistent with the role of PGC-1α in inducing mitochondrial biogenesis, it also shifts skeletal muscle fiber composition towards type I [298, 299] and type IIa , which are more oxidative. AMPK also contributes to fiber type changes and is required for the transition of highly glycolytic, type IIb fibers to more oxidative, type IIa fibers . Although PGC-1α is primarily known for inducing transcription of nuclear DNA, it may also, in conjunction with SIRT1, induce expression of mtDNA .
A joint interim statement of the International Diabetes Federation Task Force on Epidemiology and Prevention; National Heart, Lung, and Blood Institute; American Heart Association; World Heart Federation; International Atherosclerosis Society; and International Association for the Study of Obesity published a guideline to harmonize the definition of the metabolic syndrome. This definition recognizes that the risk associated with a particular waist measurement will differ in different populations. Whether it is better at this time to set the level at which risk starts to increase or at which there is already substantially increased risk will be up to local decision-making groups. However, for international comparisons and to facilitate the etiology, it is critical that a commonly agreed-upon set of criteria be used worldwide, with agreed-upon cut points for different ethnic groups and sexes. There are many people in the world of mixed ethnicity, and in those cases, pragmatic decisions will have to be made. Therefore, an international criterion of overweight (BMI≥25) may be more appropriate than ethnic specific criteria of abdominal obesity for an anthropometric component of this syndrome which results from an excess lipid storage in adipose tissue, skeletal muscle and liver.
Ok, My last question before I try it for the 5th time. Thank you for taking the time to answer!! I know you say grind it more, but here is my dilemma. You says yours weighs 90 grams for 10 tablespoons. So, i weighed mine out (I grind in a high power vitamix) my 10 tablespoons weight 115 grams…so mine is more dense than yours. I’m torn, should I actually grind less? Buy another brand? Maybe Frontier? Thanks for any help. I am so frustrated not having a bread sub for my grain free family 🙁 I tried protein bread but I have this awful aversion to cream cheese taste and can’t seem to get over it 🙁 Even if I could just get a baguette or roll to work out I’d be so happy! I get my hubby’s hopes up every time it bakes because it smells so good! Thanks again!
Although resting skeletal muscle is less metabolically active than the heart, kidneys, brain, or liver, it rivals even the brain in being the body's most metabolically demanding tissue when considered relative to total tissue mass . Physical activity can greatly increase this demand, making exercise a practical and powerful way to induce bioenergetic adaptations.
