It sounds pretty reasonable-- inwards fact, so reasonable that it's commonly stated equally fact inwards pop media in addition to inwards casual conversation. This sentiment is so deeply ingrained inwards the pop head that people often enjoin "I convey depression blood sugar" instead of "I'm hungry" or "I'm tired". But this hypothesis has a big problem: despite extensive research, it hasn't been clearly supported. I've written close this number earlier (1).
Influenza A virus subtype H5N1 novel study offers a straightforward exam of the hypothesis, in addition to in 1 lawsuit once again finds it lacking.
The study
Bernd Schultes in addition to colleagues used a clever blueprint to isolate the consequence of blood glucose on appetite (2). They recruited fifteen salubrious immature men, in addition to on 2 occasions fed them an identical low-cal breakfast.
On 1 occasion, they waited 1 threescore minutes after the repast in addition to infused saline containing fifty grams of glucose into the volunteers' bloodstream over a one-hour period. On the other occasion, they did the same affair except using saline without glucose. Throughout the infusion, in addition to 1 threescore minutes afterward, the researchers monitored levels of blood glucose, blood insulin, in addition to markers of appetite.
The results
As expected, the glucose infusion markedly increased blood glucose in addition to insulin levels inwards the threescore minutes next the meal. After the researchers stopped the glucose infusion, the volunteers' blood glucose levels declined, eventually reaching a grade significantly lower than the command status (54 mg/dL vs seventy mg/dL). This is the post-meal "crash" that is supposed to trigger appetite.
Yet levels of hunger, appetite, satiety, in addition to fullness didn't differ betwixt groups at whatever time-- either during the infusion or afterward.
Discussion
We convey extensive bear witness that the encephalon pays attending to blood glucose levels, in addition to triggers appetite when it goes likewise depression equally piece of occupation of a suite of protective responses to hold blood glucose grade (this is called the "counterregulatory response"). However, the bear witness overall suggests that you lot convey to convey pretty serious hypoglycemia for this to happen-- something that rarely occurs inwards people who aren't using insulin to process diabetes. When researchers genuinely mensurate the blood glucose grade of non-diabetic people who written report feeling "hypoglycemic", a pocket-size per centum of them genuinely are hypoglycemic, but the vast bulk convey perfectly normal blood glucose levels (3, 4, 5, 6). Hypoglycemia is non something that occurs oftentimes inwards the full general non-diabetic population, in addition to it doesn't offering a compelling explanation for why nosotros experience hungry or tired betwixt meals.
The encephalon listens to a diverseness of signals that betoken the body's liberate energy status, in addition to it integrates these signals to create upwards one's hear your sensation of hunger or satiety (7). Glucose is 1 of the signals the encephalon listens to, but at that spot are many others, in addition to the encephalon doesn't appear to pay real much attending to the glucose signal when it's inside the attain that occurs inwards the daily life of most people. In contrast, the encephalon pays attending to levels of leptin, CCK, GLP-1, glucagon, amylin, ghrelin, in addition to signals ascending from the gut via the vagus nervus (7).
I similar this study because it manipulated blood glucose levels inwards a mode that's non probable to last confounded yesteryear variables that bedevil other study designs. They pulled this off yesteryear straight manipulating blood glucose, mimicking the glucose profile of a high-glycemic repast to run into if post-meal fluctuations at the extreme destination of the normal attain impact appetite.
And, consistent amongst most previous research, it looks similar they don't. How create nosotros reconcile this amongst the fact that some single-meal studies convey establish that lower-glycemic meals are to a greater extent than sating than higher-glycemic meals (8)? Here's what I think. The sating consequence of low-glycemic meals likely doesn't convey much to create amongst blood glucose at all, but rather: 1) the fact that these studies are ordinarily non properly controlled for other variables known to impact satiety, such equally calorie density, fiber, protein, in addition to palatability; in addition to 2) the fact that lower-glycemic foods digest to a greater extent than piece of cake in addition to thus tend to exit refined saccharify hanging or so inwards the gut interacting amongst intestinal satiety receptors for longer.
The authors conclude:

Tips Today Create Blood Glucose Levels Acquit On Hunger In Addition To Satiety?
You've heard the story before: when you lot swallow carbohydrate-rich foods that digest quickly, it sends your blood refined saccharify in addition to insulin levels soaring, so your blood refined saccharify grade comes crashing dorsum downwards in addition to you lot experience hungry in addition to cranky. You achieve for to a greater extent than carbohydrate, perpetuating the cycle of crashes, overeating, in addition to fatty gain.It sounds pretty reasonable-- inwards fact, so reasonable that it's commonly stated equally fact inwards pop media in addition to inwards casual conversation. This sentiment is so deeply ingrained inwards the pop head that people often enjoin "I convey depression blood sugar" instead of "I'm hungry" or "I'm tired".

The authors conclude:
These findings clearly utter against the notion that fluctuations inwards glycemia in addition to also insulinemia stand upwards for major signals inwards the short-term rule of hunger in addition to satiety.Bariatric doc Arya Sharma also had some skillful thoughts on this study (9):
The lesson here, I estimate is that, only because at that spot is a seemingly compelling narrative to back upwards an idea, it does non hateful that that’s how biological scientific discipline inwards existent life genuinely works.I agree!
