Anyone only eat food? (not taking supplements) /r/nutrition Once glucose is inside the liver, glucose is phosphorylated into glucose-6-phosphate, or G6P.
G6P is further metabolized into triglycerides, fatty acids, glycogen or energy.
Glycogen is the form in which the body stores glucose. The liver can only store about 100 g of glucose in the form of glycogen.
The muscles also store glycogen. Muscles can store approximately 500 g of glycogen.
Because of the limited storage areas, any carbohydrates that are consumed beyond the storage capacity are converted to and stored as fat. There is practically no limit on how many calories the body can store as fat.
Once your glycogen stores are full, your body stores excess calories from carbohydrate as fat.
Excess calories from fat and protein intake get stored as fat in the body as well.
Adipose cells, or fat cells, store the extra calories in the form of triglycerides, a type of fatty acid.
Most of these fat cells are found between your skin and muscle while others surround your organs
Everyone has a different number of fat cells, but it's the size of the cells that matters more
unsaturated fats are considered more healthful than saturated fats, and it is recommended that the majority of one’s fat intake be unsaturated. This is naturally achieved, for example, by consuming vegetable oils.
There are at least two known exceptions to the rule that unsaturated fats are good and saturated fats are bad. The first exception is trans fat, which is a kind of unsaturated fat that increases levels of LDL and the risk of heart disease. Trans fat is found in small quantities in animal fat, and in much larger quantities in partially hydrogenated vegetable oils, as may be found in processed foods. The prevailing recommendation is to consume little or no trans fat.
The second exception to the "unsaturated good, saturated bad" rule is found in medium chain triglycerides (MCTs). MCTs are found in large amounts in coconut oil. MCTs are generally believed to be especially healthful fats, and in particular have been found in some studies to promote fat burning and decrease appetite.
Saturated fat, as an all-inclusive category, has not yet been shown to beneficially or adversely affect heart health. That being said, polyunsaturated and monounsaturated have been shown to improve heart health. So saturated fats are worse relative to the unsaturated fats, but they are not bad at all. [examine]
The body stores the excess protein or carbs in a person’s diet in form of fat, specifically, as triglyceride molecules, which consist of just three kinds of atoms: carbon, hydrogen and oxygen. For people to lose weight, their triglycerides must break up into building blocks, which happens in a process known as oxidation.
triglyceride oxidizes (burns) + O2 => CO2 + H2O + energy?
You might be wondering why fat molecules get broken down into glycerol and fatty acids if they’re just going to be rebuilt. This is because fat molecules are too big to easily cross cell membranes
Whenever you stop eating, your substrate preference will be about 2/3 fat and 1/3 carbohydrates. Those carbohydrates will come from stored glycogen in your liver and muscles.
When those glycogen stores run out, the liver will try to defend the blood glucose through gluconeogenesis, synthesizing glucose from amino acids from protein broken down elsewhere in the body and glycerol from triglycerides. This metabolic phase is characterized often by decreases in blood sugar and associated tiredness and hunger. It is also the phase in which muscle catabolism progresses at the fastest pace.
However, 12-24 hours after running out of glycogen, the body will gradually go into ketosis, in which the liver synthesizes ketone bodies from fatty acids. These ketone bodies can substitute and/or replace glucose in the metabolism, reducing the need for breakdown of protein for amino acids for gluconeogenesis. After a couple of days the substrate preference will have changed to 90% fat and 10% carbohydrates, thereby reducing muscle catabolism strongly. This state can be maintained for as long as there is enough fat. The longest documented therapeutic fast was 385 days during 100+ kg weight loss in an obese patient. Mind you that a kg of bodyfat contains enough energy to go for 3-6 days depending on body size and activity level.
Ketosis and relying predominantly on fats will continue until only the essential bodyfat stores are left at approximately 5-7% in men and 10-14% in women. At this level the substrate preference for fats disappear and muscle catabolism increase sharply again. At this point death will usually occur within very few weeks.
Gluconeogenesis highly prioritizes fat metabolism for energy when carbohydrate based sources of glucose are low/empty.
The entire purpose of fat is to be an energy source when other sources are low, whereas the purpose of muscles are either locomotion or stability.
It would be hard to imagine evolution leaving you as an atrophied blob of fat in an emergency situation.
lcohol (pure ethanol) calories are just like any other calorie
alcohol is metabolised to Acetaldehyde (which is toxic and makes people feel like shite), and then to Acetic Acid which is metabolised into AcetylCoA, which then substitutes into the Krebs cycle (with oxaloacetate) as normal and is used to produce energy at a cellular level
when you ingest alcohol the body then uses as the preferential source of energy, and as a result burning of any other macronutrients is suppressed, which makes them more likely to be converted to fat and then stored rather than used for energy.

Consider supplementing with vitamin D and probiotics. Levels of magnesium, iodine and vitamin K2 should also be optimized. Iodine can be obtained from seaweeds. You probably donβt need a multivitamin or other supplements.
Many low-carb diet authors recommend supplementing B and C vitamins with extra-strong dosages. If you are on a ketogenic diet, with only 20-30g of carbs a day, you could go as high as 2000-3000% of NRV for B and C vitamins.

Humans have a 2 million year history of meat consumption, ever since we started hunting and experienced a dietary transition as a result. Nut consumption is 800k years old. Fish consumption is 50k-10k years old. Agriculture is 40k-10k years old depending on source

Check out this USDA paper which compares the nutrient levels of various types of foods and cooking methods. Specifically, on page 6, there are lines which provide comparisons of various cooking methods and their nutrient retention rates. Check the line:
3006 11 VEG,GREENS,BOILED,WATER USED
You can see in the table that there are only two nutrients that lose significant quantities due to cooking, vitamin C and folate, with losses of 25% and 30% respectively. However, if you cooked the greens and drained the cooking water, then your losses would be greater (45% and 40%).
These are averages of course so slightly undercooking the greens will save more of the vitamin C and folate while overcooking will result in more losses than in the USDA paper.

Sugars affect your blood sugars [[nutrition]]and since they are carbs they have the same caloric value and no other nutritional value. Sugar alcohols are artificial sweeteners and have no impact on blood sugars. They have lesser calories too. Sugar alcohols have a laxative effect when taken in excess tho.
Yes its bad for you. Despite being in good shape, the repeated effects of high insulin spikes will certainly damage your liver/ other organs in the long run.

will all fat get absorbed? [[metabolism]]You don't absorb 100% of the nutrients in your food, if you gorge on lots of food with a decent amount of fibre a lot of it will go through you without being absorbed, especially the fat. On the other hand oily diarrhoea is usually even more unpleasant than portion control.
