A question about diet

Funny how they make it more complicated than it is. Like they are trying to sell you something

why do you try be an expert in everything


is this just part of being a grifting gypsy, you can't even help it it's in your dna

I don't proclaim to be an expert it's a subject I'm interested in. Maybe stop being an insufferable douche for just one thread?

That pathway is only used if you're in real trouble (freezing to death, for example), and it involves lactate and AA's much more than glycerol. You're nit-picking at something I suspect you googled, and are trying to invite me to a gun-fight while you're holding a paperclip.

In general, dietary proteins contribute little to glucose production, and fats, almost none. 6th grade explanation: In your liver mostly, lipase breaks fats into fatty acids, which are moved by blood into the mitochondria of skeletal muscle, and yield ATP, via citric acid cycle. Fat can be an excellent source of energy (as you're sitting on your computer chair reading this, about 80% of the energy you are using is coming from fat), and oxidation of fatty acids can become more efficient with training. Long periods of aerobic exercise with little carbohydrate consumption deplete glycogen stores (in the liver and sarcolemma), and force increased production of lipase (liver and other places, but mostly liver), and acetyl coenzyme A in the mitochondria. Over months of this, mitochondrial density can be increased.

For juggernaut: If you not eat lot food, and exercise slow and long time anyway, you will get gooder at picking fat for teh go-go juice.

Which pathways are being used in people on strict zero carb diets?

Biochemistry is a rapidly advancing academic discipline that has elucidated more detail on how we should eat and exercise if we want to live longer and less medicated lives. You don't have to understand all the enzyme names and long-words to get the general take-home message.

To a point, yes. More research is piling up pointing the finger at refined and processed food being one of the silent culprits in the explosion of cancer we've seen in the last century. We don't know the exact mechanism of the link yet, but it's being worked on.

SuperTrap said:
Control your portions. Brisk 1 mile walk per day, every day.

Yes to portions. Americans eat heaps more food than they actually need, and again, a link is suspected between this and a dozen different types of cancers. Restricted calories has shown itself to improve health in many different axes.

As far as your exercise prescription, it isn't well-supported by experiment. A more exact way is to exercise by intensity and time. You don't need an HR monitor for this, going by RPE is just fine. American heart association is recommending 45 minutes of aerobic exercise, so for "folks," that means more like 2 miles a day.

No, it's not. I'm not calling you out when I say I hope you find a smoking cessation program, or just stop. I like responding to you, and hope you're here for a while.
 
How do you control what you eat if you don't even understand what you're eating? For ignorant fat people this is a serious consideration.
 
Studies show both that people massively underestimate their own daily caloric intake, and that food labels are notoriously inaccurate. Just fyi.

You have to have the motivation to learn about the food you're eating and to put in the effort to track it accurately. That's just my opinion of course, but I really don't think long term positive lifestyle change is possible without this knowledge. See: yoyo effect in fad dieting.

There is no metabolic pathway to break fat down into glucose. Fat ----> ATP via Acetyl Coenzyme A and the citric acid cycle. Mammals cannot make sugar from fat.

Intermittent fasting has been a staple of endurance training for decades.

gluconeogenesis.
 
Fats are broken down to glycerol and fatty acids during the process of lipolysis. The fatty acids can then be broken down directly to get energy, or can be used to make glucose via gluconeogenesis. In gluconeogenesis, amino acids can also be used to make glucose.
