Serious Zero carb/Low carb diets suck (1 Viewer)

If I see one more mother fucker talking about how eating raw meat and zero carbs is some insane ascension method I am going to explode.

First off If you have any understanding of how the body works insanely low carb/no carb diets are first off horrible for the gym as to have a sufficient amount of motor unit recruitment the gym you need glucose.(More recruitment = more force output = more muscle stimulus)

The Effect of Carbohydrate Intake on Strength and Resistance Training Performance: Systemic Review​

What the highlighted text is showing is that being glycogen depleted causes premature fatigue leading to less muscle growth. It also shows that training in a glycogen depleted state lowers ATP synthesis so your muscles can't regenerate energy fast enough to sustain contractions.

Slower Metabolism ​

Your thyroid secretes mostly inactive T4 which must be converted to active T3 in the liver. Low carb/zero carbs chronically drops blood sugar spikes therefore spiking cortisol then cortisol blocks the 5'-deiodinase enzyme that converts T4 to T3 leading to more T4 gets
shunted into Reverse T3, which is inactive and actually blocks T3 receptors. A 1985 study found T3 declined from 198- 113 mcg/dL on a high fat low carb diet. REFERENCE https://pubmed.ncbi.nlm.nih.gov/3900181/

Less Bioavailable Testosterone​

When you eat carbs blood glucose rises then glucose enters liver cells where glucose gets converted to fatty acids via lipogenesis those fatty acids downregulate HNF-4α activity (HNF-4α stops driving SHBG gene expression) so SHBG production drops. So when you go no carb/low carb you have no glucose, no lipogenesis so HNF-4α stays highly active so SHBG gene keeps getting transcribed and then SHBG rises. We can see this in a lot of carnivore influencer's like Paul Saladino's bloodwork on carnivore showed SHBG at ~80 nmol/L which is nearly 2-3x the upper normal range.

Albumin Complication​

On a ketogenic or very low carb diet, elevated fatty acids in blood increase albumin's binding strength for testosterone meaning even the albumin-bound (normally bioavailable) fraction becomes less accessible. So low carbs hits bioavailable testosterone twice: Raises SHBG and Raises fatty acids so albumin holds testosterone more tightly less of that fraction releases either
