The purpose of fasting before a procedure involving anesthesia is to avoid aspiration of stomach contents, not anything related to drug efficacy. Your anesthesiologist/physician/dentist/nurse wants you to have an empty stomach so you don't regurgitate and then inhale food while your reflexes are suppressed. Fasting procedures can depend on the specific ...

Retest I generally retest and don't base decisions on a single reading. Although the impact of the mint would seem minimal, the abnormal result itself deserves repeating. Unfortunately, insulin resistance has become a huge problem and I see it all the time in clinical practice and am no longer surprised when a fit appearing person or an athlete I work with ...

OK, so this seems to be a 24 hour fast. Salt (sodium) and glycerol, after drinking water, prolong the time in which the water is excreted from the body, but they both work only for few hours. The idea of hyperhydration to delay dehydration sounds interesting for marathon runners (in order to avoid the need to drink during the race), but according to ...

Fasting, at least in Islam, means no water intake during the fast. The Islamic purpose of not allowing even water is to remind one that one should not take for granted the gifts of life. So, the purpose of the injunction is to remind you, and not to imperil your health. In the same way that the pillars of Islam have modifiers ( like not going to Mecca if ...

It is generally considered that less than 50kcal is acceptable during periods of fasting. This obviously doesn't mean 10 50kcal in quick succession is acceptable (that is considered a 500kcal meal). I personally would not be held-up on the fact. In terms of calcium and vitamin supplementation it is generally advised that they are consumed with a meal. In ...

Quality of Evidence First off, I'd be careful with the sources you are citing-- one of them is an opinion letter in a journal, and two are studies in rats. When looking at studies, the best evidence is that with patient-centered outcomes (5). Increased dentate gyrus neurogenesis or HGH production are interesting results, but it's unclear that those ...

Here's one long review article with lots of references that mentions eventual health benefits of fasting: Longo VD et al, 2014 Fasting: Molecular Mechanisms and Clinical Applications (PubMed Central) I personally do not see fasting as a method to improve health, detoxify or lose weight but rather as something that can help spiritually. So, I do not want ...

In summary, intermittent fasting could help decrease appetite and thus make weight loss easier for some people, but there is no convincing evidence that it would stimulate catabolism more than other methods of weight loss. If you're fasting for 16 hours, eat 100 calories, then fast 16 more, how significantly different is that from fasting 32 hours? If ...

Summary A single meal can decrease the risk of hypothermia during a few km travel in severe cold. Consequently, it could also decrease the risk of frostbite, but lack of studies prevents making any reliable conclusions. Dietary protein generates more heat than carbohydrates and these more than fat. Proper hydration can contribute to prevention of ...

I have not found any studies carried out regarding a classical conditioning to increase blood glucose before exercise. However, if you do not have enough insulin available, due to diabetes for example, blood glucose levels sometimes actually go up during and after physical activity, causing the levels to be too high (hyperglycemia). Exercise can trigger ...

If thirst mitigation is your goal, then you should focus on what food and drink you SHOULDN'T take beforehand. This includes anything salty (chips, soups), diuretics (coffee, alcohol), and sugary foods. Avoid those things beforehand and you should be able to forgo thirst a little bit easier in the future.

What you may be experiencing is what is commonly referred to as the "dawn phenomenon". This is where blood sugar becomes elevated between 2-8am. This happens when your blood glucose goes low in the evening. The body compensates by releasing stored glucose from the liver. In people without diabetes the body would simply produce more insulin and regulate ...
