Fat [burning] and fasted cardio myths

Real physiology of training in a fasted state.

The popular strategy of performing morning jogs with a completely empty digestive tract relies on the illusion of exponentially blasting adiposity.

Actual biology indicates that, in the absence of fresh nutrients, the system does turn more aggressively to the triglycerides deposited internally between the filaments of muscle tissue, preparing them for the fray.

However, this slight increase in the rate of local lipid mobilization does not alter or increase the overall caloric expenditure of training.

Subjecting the body to this severe carbohydrate deprivation can unleash fearsome cortisol spikes and glucose crashes, forcing less experienced athletes to abandon the routine prematurely with no real advantage over those who ate breakfast.

Physiological fallacies about perspiration and urine

There is a proliferation of extremely dangerous anti-scientific beliefs about the material excretion of fat in sporting venues.

Physiologically, adipocytes never liquefy to be expelled through the sweat glands; attempting to wrap up in non-breathable synthetic clothing will only induce lethal dehydration without affecting a single gram of fat tissue.

Similarly, human kidneys do not filter or expel lipids through the urinary tract during healthy biological conditions.

When fat is successfully oxidized as a direct result of a strict caloric deficit, its matter disintegrates into respiratory gases and cellular metabolic moisture, categorically disproving any promise of miraculous expulsion.

The ineffectiveness of exogenous L-carnitine for weight loss

The amino acid known as L-carnitine operates naturally in the body as the exclusive vehicle that pulls fatty acid tails into the mitochondrial cauldrons for energetic cremation.

Driven by commercial logic, industries promise that gorging on this exogenous supplement will multiply lipid destruction.

However, sports science is lapidary in this respect: saturating the L-carnitine stream does not force the mitochondria to work faster, just as cramming hundreds of workers into a small factory does not increase manufacturing if there are no orders involved. Intense exercise is the only real stimulus that commands lipid mobilization.

Summary

Practicing aerobic routines under strict morning fasting does not increase the individual's desired final caloric deficit. It only alters the immediate origin of the muscle fuel , demanding a greater temporary mobilization of intramuscular stored fats.

There are profoundly absurd beliefs regarding the excretion of heavy body adipose tissue. Fat is never expelled through profuse thermal sweating or through dense renal urination under absolutely normal physiological contexts.

Various commercial supplements mass-marketed as miracle incinerators lack any validated and solid scientific backing. The endogenous cellular transporter will operate efficiently only if accompanied by an undoubtedly severe and purely energetic nutritional restriction.
