TFM often seems to endorse a low carbohydrate diet for weight loss
There is a minimum amount of carbohydrate needed for brain function. Go below that and your body starts destroying it's own protein to produce carbohydrate.
Any exercise above a certain intensity for a certain amount of time or longer requires carbohydrate fuel and in the absence of carbohydrate in your diet results in your body destroying it's own protein to produce carbohydrate or inability to exercise at that intensity
@shortstories That is not true. The brain can comfortably consume ketone bodies after an adjustment period. In the meantime, excess amino acids can be converted to glucose. If you train regularly you should be able to consume the carbs without depositing them.
You can lose muscle and still gain strength because you lost weight and because of nerve firing adaptations
I should have talked about a no carbohydrate diet.
I would estimate if you eat 700 Carbohydrate Calories that is enough if you are sedentary to reduce protein breakdown
If you exercise you need a little more carbohydrate to prevent protein breakdown
If you go under a certain amount you will break down more protein but can still gain strength due to weight loss and nerves
With no carbohydrate store left on a no carbohydrate diet
If someone's sedentary brain uses 700 Calories of carbohydrate per day they will need to eat at least 175 extra grams of protein
4 Calories per gram of protein
175 = 700 / 4
18 year old 60 Kg male
If they normally need 48 grams when sedentary they now need at least 223 grams
108 grams when strength training would become at least 283 grams of protein
Else lose muscle
Might harm kidneys
Fat no fuel brain
@shortstories @mrhorsetwat
With carnivore just eat how much you want no need to calculate.
to lose muscle you need to starve jourself for long time.
for brain fuel you have some type of glucose made of protein through Gluconeogenesis
and eating meat will not harm any of your organs. They will do the opposite.

For exercise above a certain intensity for longer than a certain duration the body normally uses a process called Anaerobic Glycolysis to produce energy by turning carbohydrates into lactic acid
On a no carbohydrate diet once carbohydrate stores are depleted
Only carbs created from protein breakdown can be used for anaerobic glycolysis
Preventing long term high intensity exercise from being possible in the relative almost complete lack of carbs to convert to lactate
@shortstories @mrhorsetwat
Normally your body is in carb dependent state if you eat carbs after you stop your body will turn to fat adapted state.
Everybody has glucose in body if they eat sugar they have stored for 1-3 days after this your body will change to fat burning state where is fat used as fuel.
Nutrient pools
Glycogen 12-24 hours
Fat 1-12 months
Protein weeks
Look on this video where Dr. Sten Ekberg explain it more.
