This picture is a bit graphic BUT I think it does a great job of demonstratinghow our bodies function with healthy food and with unhealthy food.
Snacks, crackers, lard, chips, cookies, muffins, ice-creams, croissants, cakes, sweets, red meat, and pies should be avoided.
Inform your doctor if you have recently undergone a bone scan with radioactive substances or a thyroid test a week before you are drawing the blood sample for cholesterol. Why are you asking me for personal information?We collect personal information including your contact and demographic information for the purposes of identification, account administration and display of personalised content and advertising. The carbohydrates, proteins and fats in everything you eat are digested into simple sugars (such as glucose), amino acids and free fatty acids. As time passes after your last meal, the amount of these nutrients circulating in your bloodstream starts to drop.
You’ve probably already noticed this dependence your brain has on glucose; simple things can become difficult when you’re hungry and your blood glucose levels drop. Another thing that can become more difficult when you’re hungry is behaving within socially acceptable norms, such as not snapping at people. Besides a drop in blood-glucose concentrations, another reason people can become hangry is the glucose counter-regulatory response.
When blood-glucose levels drop to a certain threshold, your brain sends instructions to several organs in your body to synthesise and release hormones that increase the amount of glucose in your bloodstream. In fact, adrenaline is one of the major hormones released into your bloodstream with the “fight or flight” response to a sudden scare, such as when you see, hear or even think something that threatens your safety. Besides acting in the brain to control hunger, neuropeptide Y and the Y1 receptor also regulate anger or aggression.
As you can see, there are several pathways that can make you prone to anger when you’re hungry. And as we are all different across all of these factors, it’s little wonder there are differences in how angry people seem to get when they’re hungry.
In these cases, it can help to remember that, with time, your glucose counter-regulatory response will kick in and your blood-glucose levels will stabilise. A final – and very civilised – way of handling hanger is to suggest that difficult situations be dealt with after food, not before! High amounts of saturated or trans-fats, high-sugar content foods, processed food products with hydrogenated oils, coconut oil, cheese, palm oil and butter should be avoided for accurate results.

However, in the recent past, finger stick tests for cholesterol level readings were introduced where people can test for blood cholesterol levels on the spot using portable machines.
Researchers found the blood tests showed similar average total cholesterol and "good" HDL cholesterol readings, in particular, regardless of whether patients had eaten recently or avoided food for more than eight hours, as is typically recommended. These nutrients pass into your bloodstream from where they are distributed to your organs and tissues and used for energy. If your blood-glucose levels fall far enough, your brain will perceive it as a life-threatening situation. So while you may be able to conjure up enough brain power to avoid being grumpy with important colleagues, you may let your guard down and inadvertently snap at the people you are most relaxed with or care most about, such as partners and friends. These latter two glucose counter-regulatory hormones are stress hormones that are released into your bloodstream in all sorts of stressful situations, not just when you experience the physical stress of low blood-glucose levels.
Just as you might easily shout out in anger at someone during the “fight or flight” response, the flood of adrenaline you get during the glucose counter-regulatory response can promote a similar response. The product of one such gene is neuropeptide Y, a natural brain chemical released into the brain when you are hungry.
In keeping with this, people with high levels of neuropeptide Y in their cerebrospinal fluid also tend to show high levels of impulse aggression. Culture influences whether you express verbal aggression directly or indirectly, for instance. While you may hanker for quick-fix foods, such as chocolate and potato chips, when you’re in the throes of hanger, junk foods generally induce large rises in blood-glucose levels that come crashing down fast. So think nutrient-rich, natural foods that help satisfy hunger for as long as possible, without excess kilojoules. This may be the case during long shifts at work, for instance, or through religious fasts such as Ramadan, or during weight-loss diets that involve severe energy restriction (such as intermittent fasting diets). Also, when you go without food, your body starts breaking down its own fat stores for energy, some of which are converted by your body into ketones, a product of fat metabolism. Just uploaded a new health video talking about 3 ways to stop craving bad unhealthy food, like fast food and sweets. Eliminating the fasting requirement before cholesterol tests would be more convenient for patients and for labs, which often get slammed with tests in the morning when most fasting patients come in, researchers said. If so, you’ve experienced “hangry” (an amalgam of hungry and angry) – the phenomenon whereby some people get grumpy and short-tempered when they’re overdue for a feed.

You see, unlike most other organs and tissues in your body which can use a variety of nutrients to keep functioning, your brain is critically dependent on glucose to do its job.
It stimulates voracious feeding behaviours by acting on a variety of receptors in the brain, including one called the Y1 receptor. Think about it like this: if hungry organisms stood back and graciously let others eat before them, their species could die out. Ketones are thought to help keep your hunger under control because your brain can use ketones in place of glucose for fuel. I LOVE doing these types of videos because I think feeling good in your own body and being proud of your body is such an important thing.
And it seems like you guys like them too, so that makes me happy :) Feel free to leave more health-related video requests down below in the comments - as well as any others you may have. If we fix this crave the first time with fruits and veggies, even though it might not be as mentally satisfying at that very moment, you will start to notice the difference long term. Requiring a fasting cholesterol test may also mean patients have to return for lab work after their initial appointment - and some may not come back, Gaziano pointed out. Christopher Naugler from the University of Calgary in Alberta analyzed cholesterol test results for more than 200,000 people who had most recently eaten anywhere from less than one hour to more than 16 hours earlier. They calculated the average cholesterol levels at a given fasting time and found that both total cholesterol and HDL varied by less than two percent across the range of fasting durations. Those numbers are typically the ones doctors use to help calculate patients' risk of heart problems and whether they should be on cholesterol-lowering statins. That suggests certain patients - such as those with high triglycerides or with diabetes, which is linked to triglyceride and LDL levels - should continue to fast before the tests. For most, a non-fasting test would be "a reasonable alternative," the researchers reported. Gaziano said patients can discuss with their doctors whether they really need to fast before their own cholesterol test, but it may take a while for non-fasting tests to become the norm.
Another commentary printed alongside the study noted that this is a relatively low-risk group, and fasting and non-fasting results may not be as similar for people with much higher cholesterol, for example.
