More Vitamin C notes

It's not that vitamin C is the new weight loss wonder drug, but the discovery that consuming an inadequate amount of the vitamin can hinder weight loss.

Does too little Vit C slow metabolism?

According to researchers from Arizona State University, individuals consuming sufficient amounts of vitamin C oxidize (burn) 30% more fat during moderate exercise than those who consume insufficient amounts. In addition, too little vitamin C in the bloodstream has been shown to correlate with increased body fat and waist measurements.

The US RDA (recommended daily allowance) of vitamin C for adults 19 years and older is 90 mg for males and 75 mg for females. Since our bodies can’t manufacture vitamin C, we must obtain it through our diet.

Roughly 40% of men and 38% of women 19 and older don't get enough.

Vitamin C status is inversely related to body mass. Individuals with adequate vitamin C status oxidize 30% more fat during a moderate exercise bout than individuals with low vitamin C status; thus, vitamin C depleted individuals may be more resistant to fat mass loss.

Vitamin C status is associated with tissue carnitine concentrations and fat oxidation and may represent a modifiable condition that would impact fat oxidation thereby affecting body composition and body mass.

From Wipi -- Carnitine is a quaternary ammonium compound biosynthesized from the amino acids lysine and methionine.[1] In living cells, it is required for the transport of fatty acids from the cytosol into themitochondria during the breakdown of lipids (fats) for the generation of metabolic energy. It is often sold as a nutritional supplement.

Note: Vit C seems to reduce hunger and raise blood sugar or blood sugar measurement. Perhaps it is just sparing glucose, but the effect seems to be real. 

to slow digestion:
The glycemic response to food ingestion has been associated with subsequent hunger; complementary foods, such as vinegar or peanut products, when added to meals, may attenuate meal-time glycemia promoting satiety and reduced energy intake.

Legumes, Lectins. Yum, slow digestion, why not include beans, the undigestible. Let the bacteria digest them, then digest the bacteria.
