Fixed that for you.

Pardon my non Doctor brain but isn't acute inflammation actually good for you?

Yes and no. Inflammation is part of the healing / immune response. 

 

The kind of inflammation we're talking about is chronic systemic low-grade inflammation.

Is there any benefit really to doing a full day fast once a week or so?

You mean besides lower weekly calories, given you eat as much the rest of the days of the week? Not sure. Probably not very good for keeping muscle mass and keeping cheat cravings in check.

 

However, if you want to reduce calories for losing weight (which I assume is your goal), its just easier to do something like a not-so-strict IF by skipping breakfast every day.

Thanks for the info @MGoCrimson

I wish I could use it. Problem is the only way I can stick to a cut is to go crazy high protein. At least 40% of calories and more like 50% on average. For me, on a cut, carbs are the enemy.... they just don't satiate like protein and fat. I think it's good to know what's ideal from a physiological standpoint but w/o adherence a lot of that shit goes out the window. Not trying to dump on the info... just bummed I can't apply it.

I've tried the no-breakfast fasting thing, which was quite easy since I don't get that hungry for breakfast. However, I started feeling crummy mid morning and noticed I was getting periodically worn out, lethargic and the sniffles here & there. I'm unsure if this was coincidental, but after switching to a light breakfast of berries and whole wheat toast (~200-250) calories I have sufficient energy until lunch and don't feel crappy at all.

I'm an American, so intermittent fasting is basically not snacking, three meals a day at 8:30, 1, and 6:30 works well for me.

I know people say that protein and fat is supposedly more satiating than carbs, but that's not my experience, particularly if you're eating the healthy carb sources.
Just sub white rice for brown, white pasta for whole wheat, and leave the skin on your potatoes and kumara and notice the difference. Maybe if your carb sources are fizzy drinks and lollies I could understand.

And to point out the obvious, fat is just way, way more calorie-dense than carbs.

As a side note, I have the smoothest shits when I eat whole wheat pasta. It's amazing.

White carbs have the highest short term satiety particularly potatoes.

Man I did all that. For me, shit like rice, pasta, potatoes etc just don't satiate like meat. The calorie density is the same

Yeah, I'm not as carb-phobic as I used to be, but I can pretty easily eat a field of potatoes and feel OK, but it can be a struggle to put down 12 or more ounces of chicken in one sitting.

Ok so satiety, briefly, is an interaction between the following:

 

Ghrelin, insulin, leptin, peptide YY, glucagon-like peptide-1, cholecystokinin, apolipoprotein AIV, and stretch receptors in the stomach. These are all anorexigenic signalling hormones/receptors except for ghrelin, which is the main "hunger" hormone. 

 

Protein is the most satiating macronutrient. It produces a lower insulin AUC than CHO, but has higher PYY, GLP-1, CCK, and post-meal ghrelin levels are suppressed longer compared to CHO.

 

Fat affects CCK and apolipoprotein AIV levels and also changes the absorption kinetics of a meal and thus has effects on the other responses. 

 

CHO and fat in isolation have been shown to have equal effects on satiety despite varying levels of aforementioned satiety hormones. 

 

 

But keep in mind studies are done with single macronutrient intakes. When you combine them, the story changes drastically, but the individual effects still hold. Also, the male hypothalamus has a stronger response to insulin whereas the female hypothalamus has a stronger response to leptin for energy intake regulation. 

 

If you're obese, your hypothalamus does not respond properly to ANY of these signals. 

 

 

 

Here are two good reviews on the endocrine side of it:

 

Appetite signaling: From gut peptides and enteric nerves to brain

http://www.ncbi.nlm.nih.gov/pubmed/17582445

 

The endocrinology of food intake

http://www.ncbi.nlm.nih.gov/pubmed/23877425

 

 

I can post the full texts if someone would like to suggest a decent file hosting site

The effects of leptin are pretty easily overcome though. It reflects fat stores, but you get some resistance and need more to compensate.

Obviously the extreme example here is with obesity, which isn't the population were talking about.

Edit: Err sorry some tolerance in most people, resistance in obesity.
