Getting defensive is not helping your case.
I'm not getting that defensive. Its just that all of the people that have commented on my quotes keep saying that I'm wrong and won't prove it, telling me I'm not doing my homework when I gave the facts.
As for Oz -- I never said he wasn't a doctor. But, a heart surgeon? Lovely but irrelevant
Actually you did mention that he was a fake health expert in the quote below. It may help your case as well to just state the facts, not assumptions that you may make that aren't true.
and read from real experts. As for Dr. Oz, as I recall, there are any number of scams being perpetrated in his name (you see them all the time as "Dr. Oz lost 40 lbs.!" or "Rachael Ray lost 30 lbs.!" or whatever).
Now anyway, let's get down to the facts shall we?
a 150-pound person will burn close to 800 calories by running 7 mph for an hour--a brisk jogging pace. We'll leave this fact to the side for now while I explain the facts of sleep.
during this stage of sleep your eyes will show rapid movements and your pulse and breathing will increase. Dreaming occurs during this stage and your fingers, legs and face may twitch. REM sleep starts 90 minutes after you fall asleep and can last an hour. Your core temperature also rises and you burn calories more easily. But it also depends on what you have eaten during the day, muscle mass, and how long you sleep that determines how many calories you will burn in sleep.
If say one day you eat more protein in your food than fats and carbohrdrates, that will increase to twice as many calories digesting protein as it does carbohydrates or fats. So then, while a person burns 150 calories per hour during REM sleep it doubles based on what they ate in their day. This is something that doesn't work when you're on a treadmill. This is because, what you eat before going on a treadmill it doen't help burn calories like sleep does. You will still burn the initial amount or calories that you already burn from just running on a treadmill alone.
Low levels of B vitamins in your body can leave you feeling depressed, which can in turn slow your metabolism. So if you run on a treadmill without having B vitamins in your system, it can decrease the amount of calories you have worked hard to burn on a treadmill. This is just one of the reasons why calorie measures taken on a treadmill are not as accurate as taking notes of everything you have eaten in a day and apply it to your personal bmr as well as counting for muscle mass and your heart rate at your climax of pace in your workout.
So what happens when you get less than 61/2 hours of sleep? It leads to weight gain. This is because leptin and ghrelin, the hormones that control whether you are hungry or not, are not produced in a sufficient amount that the body needs to regulate hunger. Therefore, lack of sleep not only gives you less calorie-burning than with sleep, but also increases weight gain by your increased appitite the next day.
As extra proof, at the University of Chicago in Illinois, they did a study on these hormones to learn of their effects on the human body. In the study, doctors measured levels of leptin and ghrelin in 12 healthy men. They also noted their hunger and appetite levels. Soon after, the men were subjected to two days of sleep deprivation followed by two days of extended sleep. During this time doctors continued to monitor hormone levels, appetite, and activity.
The end result: When sleep was restricted, leptin levels went down and ghrelin levels went up. What leptin does is it tells you that you're full. Ghrelin tells you you're hungry. Not surprisingly, the men's appetite also increased proportionally. Their desire for high carbohydrate, calorie-dense foods increased by a whopping 45%.
