Never had that problem, I love apples when I'm dieting. Low calories, good amount of fiber, not very dense so you get a lot of volume for those calories. Sure it's sugar (which may make some people hungry) but unless you're going ketogenic it's not that big a problem.

This thread inspired me to eat an apple.

When I eased myself onto the WD/IF, I was eating an apple for lunch. Now, not so much.

happens all the time. I googled it years ago and think it has something to do with the acidity. Apples are the worst, man. I usually follow that up with candy cause it hurts my belly.

Maybe because it's a catabolic food? I don't know, does not happen to me unless I'm very hungry to begin with.

It shouldn't. Apples are high in dietary fiber.

Essentially the carbs in the apple cause a pancreatic insulin secretion which transport nutrients from the bloodstream into storage, thus making you feel more hungry. The fructose content can also have an effect on leptin signals, which regulate hunger.

It's not really going to have that great of an effect in the short term on Leptin.

While I agree chronic consumption will definitely pose more of an effect than acute ingestion of fructose, the fact that fructose lowers circulating levels of leptin certainly can be a contributing reason as to why he's feeling hungrier. I'm just hypothesizing here. http://jcem.endojournals.org/cgi/con...ract/89/6/2963

Because insulin and leptin, and possibly ghrelin, function as key signals to the central nervous system in the long-term regulation of energy balance, decreases of circulating insulin and leptin and increased ghrelin concentrations, as demonstrated in this study, could lead to increased caloric intake and ultimately contribute to weight gain and obesity during chronic consumption of diets high in fructose.

You don't really see sustained (or imo physiologically significant) differences until after the consumption of the second high fructose meal. Look up this paper "Twenty-four-hour endocrine and metabolic profiles following
consumption of high-fructose corn syrup-, sucrose-, fructose-, and
glucose-sweetened beverages with meals" by Stanhope et al. and you'll see the same thing.

Interesting. Thanks for the reference.

we could go into it... really deep into it... but from my experience people eat apples as snacks...

simply put the apple just makes you hungry because your body is prepared to eat a full meal anyway.

so things like a mid day 4pm snack you're on the brink of being really hungry for dinner and a apple serves as a "appetizer": the small intestines gets the fiber (bulk of probably 4oz or 30gm), and the sugar kicks in the insulin release, and then thats it. basically you're just starting the engine (GI metabolism) and it naturally wants more when it only feels 30gms of bulk in it, but the GI has blood flowing to it like a normal meal.

from a physiology standpoint it would make sense to eat an apple then go for a walk/exercise. because then you'd pull that blood that was going to the GI tract back to the muscles and slow down the metabolic process theoretically making you less hungry.

this is a phenomena of people who work out in the morning (even heavily like running 5 miles) on an empty stomach (right after waking up). you start out hungry but then actually can finish the workout and not feel hungry afterwards. (current trends actually have coaches/trainers force feeding minutes after working out - to avoid drastic swings in appetite).
