Why exercise does not cause weight loss. I.E. CICO is for dumb people - The Scribble Pad

The Scribble Pad: Why exercise does not cause weight loss. I.E. CICO is for dumb people.

Increasing "energy out", otherwise known as boosting your metabolic rate, or exercising more, does NOT result in body fat loss. This is because body fat is regulated by a myriad of hormone / endocrine signals, most specifically leptin.

Expecting to raise energy needs and lose body fat from creating a "calorie deficit" is like trying to hold your breath to reduce your respiratory rate. Guess what happens? You breathe frantically when you let your guard down. Even assuming you temporarily maintain the lower respiratory rate, while actively in the slow breathing condition, a myriad of physiological changes occur to maintain equilibrium and adapt to the reduced oxygenation / increased carbon dioxide in the blood.  Our respiratory rate is matched to our need for oxygen and to blow off carbon dioxide. The body is capable of adapting to a lower availability of oxygen (e.g. disassociating more oxygen from hemoglobin, otherwise known as a declining o2 saturation... in normal people it's usually about 98%, in hypoxic people it can go below 93% which is considered insufficient.... or, if carbon dioxide is increasing, to prevent impending respiratory acidosis the body can adapt by utilizing metabolic mechanisms to alkalize the blood such as blood cells swapping hydrogen for potassium, which helps buffer the acidic effect of retaining carbon dioxide. Hyperkalemia is an effect of anything that promotes acidosis for this reason (e.g. uncontrolled diabetes being notable / hall mark example, as not only are ketones acidic actively promoting metabolic acidosis but insulin is required very intimately to help regulate electrolytes and prevent shift of potassium out of cells).


Well kiddies, general medical info, I digress big time... but the point I am making is that eating behavior is not one iota different from breathing behavior over a long term continuum of time. This is what dumb bells like carbsane don't get. You can't exert "willpower" to eat less because you will induce an imbalanced state that promotes very strong hunger (just like under-breathing promotes very strong drive to breath) and if you resist the eating (temporarily, always) your physiology adapts to a starvation condtiion by slowing energy use and all metabolic process, as well as shunting more energy to storage (fat) relative to heat, energy production, or synthesis of non-fat tissue.


What is so complicated to understand about this? Eating is not random. People eat 100% and always and never for any reason other than the endocrinological prompts of their body. The nervous system at best modulates endocrine state of body, but ultimately how much you eat and how much fat you store is not any less than 100% an endocrine proposition over a long term trend of time.

People are very dim. They are also very very arrogant. "You mean my physiology absolutely controls me like a slave? You mean I'm not choosing to eat too much and be fat? BUT NOOOO! I am such a smart special human being totally in control / able to be in control of myself at all times" <~~ um actually you are an animal, and a DUMB animal at that.


Progesterone - noted to increase metabolic rate, sure. Hypothetically people should lose weight with supraphysiological progesterone. Good thing we aren't stupid and we understand body fat anabolism is always a metabolic/endocrine proposition, therefore the "rate" of metabolism means jack and shit for determining whether or not something is obesigenic! Yes, progesterone increases metabolism, increases body temperature, but it is well known and notoriously obesigenic. It ruins glucose tolerance, it literally tells your fat cells to store more energy by not only promoting hypertrophy/bias of insulin sensitivity, but also directly promoting adipogenesis of white fat around the mid section (which, BTW, is why women loose their figures with increasing age and especially after child birth - progesterone is very specific for pregnancy, raises total body fat permanently especially around the mid section. Women with smaller waists are basically advertising nulligravida status. Either that or great hollywood surgeons.)

Exercise increases metabolic rate, reduces insulin, promotes body fat oxidation/increases ketogenesis.  Exercise actually can promote long term weight loss *if* it helps normalize glucose tolerance / hyperinsulinemia when it is pathological, just like lowering carbohydrate can do this as well. However, if one is already at a "leptin stable, weight stable" type condition, meaning to say your leptin levels are LOW and ADEQUATE for maintaining minimum body fat, all exercise will accomplish is one monster appetite (and, if you try not to eat enough, then you induce upon yourself a complex metabolic/endocrine/nervous system imbalance known as semi-starvation. See athletes triad and eating disorders for more info as to what happens, don't have time to go into all of this here, but basically if your leptin is too low for too long because you're exercising and not eating (or simply just not eating, without exercise) then your body says F.U. and refuses to work.)

Here, with exericse, we see yet another example of increasing "metabolic rate" but not reducing body fat. The body merely adapts to conserve energy, and increase appetite (with the only noted exception being when exericise is used as an insulin sensitizing agent in people who have pathological insulinemia; then exercise may promote healthy/sustainable body fat reduction by correcting hyperinsulinemia and metabolic disorder).


Just felt like writing this after observing myself working like a crackhead, with high progesterone... so much "energy out" but guess what? My appetite is non-stop and I just eat way more calories than usual.
I don't simply lose weight from all the activity.... my hunger increases accordingly and I eat 25% more calories than usual.

CICO amounts to religion as far as I am concerned. It is irrational, illogical, more than sufficient evidence exists to conclude it is false, etc. People continue to believe in it because of their moral and emotional feelings about body fat and obesity and human control/willpower. All successful CICO is basically a variant of mental illness, for it requires continuously denying your drive to eat, which is not mentally healthy.

Quick 15 minute post before bedtime! Yes, work the next 2 days, sorry no responses to comments yet again :( :( :(
