How does green tea work? Should it be necessarily green tea?
The green tea extract may play a role in the control of body composition via activation of thermogenesis, fat oxidation, or both. First of all, green tea works by increasing energy expenditure. Green tea has thermogenic properties and promotes fat burning beyond that explained by its caffeine content per se.
Researchers at the University of Fribourg, Fribourg, Switzerland,reported that green tea extract stimulated brown adipose tissue thermogenesisto an extent which is much greater than can be attributed to its caffeinecontent, and that its thermogenic properties could reside primarily in aninteraction between its high content in catechin-polyphenols and caffeinewith an increase in noradrenaline release.
Green tea also works bynormalising lipid metabolism. Green tea extract has preventive effects onblood cholesterol suggesting that green tea has anti-atherosclerotic activity.
Should it be necessarily green tea?
Perhaps, if we are talking about the fat-burning effects. Maybe not,as it comes to the saliva enzymes inhibition. Tea decoctions prepared froma number of black and green teas inhibited amylase in human saliva. Blackteas gave higher levels of inhibition than green teas, and removal of teatannins with gelatin led to the loss of inhibitory activity from all decoctions.
Salivary amylase starts the digestion of food starches to low molecular weightfermentable carbohydrates. In a clinical experiment conducted by the Centerfor Research on the Biological Effects of Foods, Forsyth, Boston, subjects consumed salted crackers and rinsed subsequently for 30 s with black or green tea decoctions, or water. The carbohydrate Maltose concentration was reduced by up to about 70% after rinsing with the teas. Black tea decoction was significantly more effective than green tea.
Other carbohydrate modifiers
The common bean, Phaseolus vulgaris, contains an alpha-amylase inhibitor, which is one of a plant's insect defense proteins found in a number ofbean species. With a reduced amount of amylase available to break down andassimilate (digest) the carbohydrates, it can have a better chance of travelingthrough the body without being assimilated, or made available as energy,and eventually excreted rather than being used as energy or stored as fat.
If you hate cutting way down on your carbs, try CBlock.
The active ingredient is the trademarked "Trimplex" (Phaseous vulgaris) whichhas been shown to effectively partially prevent the body from absorbing starches.CBlock is safe. There have been no known reported side effects with thisproduct.
Ingredients:
White kidney bean extract 700 mg
Chromium (as chromium dinicotinate glycinate) 200 mcg
Vanadium 100 mcg
Carb Block will help prevent up to 38 grams of sugars and carbs from being absorbed.
Carb Block also provides a second, equally important benefit. Gymnemalin, an extract of the plant Gymnema sylvestre, is a hypoglycemic agent. Whencombined with the patented chromium formula, alpha lipoic acid and vanadium,Gymnemalin will improves insulin function and sensitivity thus preventingyour body from sharp increases in insulin levels following a carbohydrate-richmeal
