"Obesity continues to increase rapidly in the United States. To alter this trend, strategies and programs for weight maintenance as well as weight reduction must become a higher public health priority:-The prevalence of obesity (defined as a body mass index >30 kg/m2) increased from 12.0% in 1991 to 17.9% in 1998. A steady increase was observed in all states; in both sexes; across age groups, races, educational levels; and occurred regardless of smoking status. The greatest magnitude of increase was found in the following groups: 18- to 29-year-olds (7.1% to 12.1%), those with some college education (10.6% to 17.8%), and those of Hispanic ethnicity (11.6% to 20.8%). The magnitude of the increased prevalence varied by region (ranging from 31.9% for mid Atlantic to 67.2% for South Atlantic, the area with the greatest increases) and by state (ranging from 11.3% for Delaware to 101.8% for Georgia, the state with the greatest increases).....";

Mitochondrial Membranes , Mg++, Malate/Oxaloacetate Translocators, Gluconeogenesis, and, Ketoacidosis....

  Hypothesis #NDC2.00 - Gluconeogenic Hormones affect Malate/Oxaloacetate Translocators or Shuttles in the mitochondrial membranes to result in (1) Increased cytoplasmic levels of OAA and
(2) Decreased
mitochondrial levels of malic acid.

  • Hypothesis #NDC2.01 - Gluconeogenic hormones - particularly AVP - directly inhibit Malic Enzyme (malate dehydrogenase) in both mitochondrial matices and cytosol.
  • Hypothesis #NDC2.02 - Insulin enhances lipogenesis by increasing mitochondrial membrane permeability to citrate and over-riding inhibition of Malic Enzyme
  • Hypothesis #NDC2.03 - Lipolysis (FFA-CoA -oxidation) results in increased mitochondrial NADH(H+) to NAD+ ratios thus further inhibiting the already endergonic conversion of malate => oxaloacetate
  • Hypothesis #NDC2.04 - Malate/Oxaloacetate Translocators (MOT) are dependent on [Mg++]'s with lower levels resulting in (1) Increased cytoplasmic levels of OAA and (2) Decreased mitochondrial levels of malic acid

"Type 2 Diabetes in whites, but not blacks, is inversely associated with serum magnesium levels................";
"Mg2+ control of respiration in isolated rat liver mitochondria.....";

 
  • Hypothesis #NDC2.05 - Increased cytoplasmic levels of OAA are gluconeogenic and insulin-antagonistic

"Transport of malate and citrate into rat brain mitochondria under hypoxia and anesthesia.....";

 
  • Hypothesis #NDC2.07 - Vasopressin is the most potent gluconeogenic hormone in this context and can -
    in the absence of sufficient insulin-induced compensation - virtually abolish mitochondrial levels of OAA.
    This results in inability to metabolize Acetyl-CoA-SH and severe ketosis with acidosis
  • Hypothesis #NDC2.08 - Dehydration (through vomiting and/or diarrhea and/or sweating and/or hypodipsia)
    is the major pathophysiologic cause of DKA
    (acting through significantly increased ADH-Vasopressin release)
  • Hypothesis #NDC2.09
    On one level, adaptation to ongoing maximal leptin-enhanced lipolysis may confer some degree of resistance to ketosis
    Hypothesis #NDC2.10
    On another level, leptin may compete with vasopressin to maintain mitochondrial levels of OAA
