While doctors and dieticians give advice not to eat sugar and starchy prepared foods, they don't tell when and how often to eat each. Few people will eat 600 calories of meat exclusively for an hour and wait 2 to 3 hours before eating the average of 200 calories over the time; but eating a 500 calorie hamburger on a roll would do much the same. Someone could be hungry an hour after eating ice cream and want more of anything. Eating a meal of eggs and meat, then not eating until having a meal of salad 3 hours later, then having a meat meal again to wait another 3 hours to something else could average out the intake. Confections are a danger.

Some clues are given by observing how insulin is supplied to diabetics. Spreading food intake out over long hours doesn't mean that insulin is secreted in large amounts every hour. Glucose is produced, then insulin not produced when blood glucose falls below. Basal insulin is secreted to counteract rises in blood glucose. Slow rises in glucose is the aim of knowing the glycemic index. As glucose is more evenly produced, any remainder would be used up in the hour following until there was a need for the liver to produce more by a signal that blood glucose was low.

"A normal-functioning pancreas constantly secretes insulin in two ways: basal and bolus. Basal insulin is secreted to counteract rises in blood glucose due to gluconeogenesis (formation of glucose in the liver) or hormone fluctuations caused by stressors, activity, or metabolic changes. Bolus insulin is secreted to counteract rises in blood glucose following meals

Injected insulin is designed to mimic normal pancreatic function. Basal insulin given by injection is long-acting insulin taken once or twice per day. Some examples include NPH (Humulin N, Novolin N, Novolin NPH), glargine (Lantus), and detemir (Levemir). This type of insulin works to counteract rises in blood glucose that occur independent of meal ingestion.."

"Everyone should avoid refined carbohydrates. They are bad for all of us, whether we are insulin-resistant or not. The less you eat of these the better.

The World Health Organization (WHO) officially recommends in its new 2015 guideline8) that people of all ages should limit sugar to less than 5% of total daily calories. So, if you eat 2,000 calories per day, the WHO says that no more than 100 calories should come from added sugars, including “sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.” That amounts to 26 grams of sugar per day, which is just over 2 tablespoons of sugar per day, maximum." [One gram of sugar contains 3.87 calories.]

If dieticians recommend 2000 calories a day, then eating 200 calories per hour for 10 hours would suit that. As meat takes 2 hours to digest, a 400 calorie meal (for ex: hamburger) could be part of the 200 calorie average. The danger could be to eat more than 200 calories of mostly carbs that digest in a short time like potatoes, cereal, cake, or corn, and faster would be sugar candies. a half cup of ice cream is about 250 calories but a cup of frozen yogurt is about 350; that would overload the hour and to not have one the hour after could make one feel a need for more as the spike drops.

"Even during the digestion, in general, one or two hours following a meal, insulin release from the pancreas is not continuous, but oscillates with a period of 3–6 minutes, changing from generating a blood insulin concentration more than about 800 pmol/l to less than 100 pmol/l.[44] This is thought to avoid downregulation of insulin receptors in target cells, and to assist the liver in extracting insulin from the blood.[44] This oscillation is important to consider when administering insulin-stimulating medication, since it is the oscillating blood concentration of insulin release, which should, ideally, be achieved, not a constant high concentration.[44] This may be achieved by delivering insulin rhythmically to the portal vein or by islet cell transplantation to the liver.[44] It is hoped that future insulin pumps will address this characteristic"

"If Suzy and Tom were to each eat a bagel containing 60 grams [240 calories] of carbohydrate, about half an hour after they ate that bagel, the concentration of glucose in their bloodstreams would also start to climb. But unlike what happened to our normal person, it would not start coming down half an hour after they ate. Instead, their blood sugar concentrations would go higher and higher until it would eventually reach a peak.

Suzy and Tom would experience differing peak concentrations and they may occur at different times after they eat even though could be diagnosed with the same disorder--Type 2 diabetes. That is because their bodies produce different amounts of insulin and their cells also differ in how well they can respond to that insulin. An hour after eating the bagel, the concentration of glucose in Suzy's blood might rise to 220 mg/dl, while Tom's blood sugar might rise to 275 mg/dl. During the second hour after eating, Suzy's blood sugar might drift down to 180 mg/dl, while Tom's might keep climbing to 340 mg/dl --a value very close to that which a person would reach if their body produced no insulin at all. During the third hour, Tom's blood sugar might finally start coming down while Suzy's would be close to a normal value. Finally, four long hours after eating the bagel, assuming they'd had nothing else to eat, Suzy might have a blood sugar concentration of 98 mg/dl, which is also the fasting level she noted when she measured her blood sugar the first thing in the morning. Tom's blood sugar might be much higher at 165 mg/dl. This is much higher level than Suzy's fasting level, but it is lower than Tom's fasting level which is a relatively high 175 mg/dl."
