He's full of crap. How the hell did he even get a PhD?? Furthermore, how the hell does he even get people to listen to him??0

Dr. Oz is full of crap. That is true.
He's not actually entirely wrong about eating at night, though he may not know why. There is research that shows that the circadian rhythm does exist in humans and affects our hormones based on the time of day. Hormones control digestion, so the time of day does effect weight loss, calorie intake, nutrient absorption, etc.
This is not an easy ready and much of it is over my head , but I think it illustrates the point:

Evidence for circadian integration of energetics, metabolism, and sleep in humans. In humans, many aspects of metabolism display circadian cycles, including 24-hour variation of glucose, insulin, and leptin levels (82, 83). Genome-wide association studies have also suggested connections between clock gene variation and fasting glucose levels (84, 85), obesity, and metabolic syndrome (86), raising interest in understanding the impact of circadian systems on human disease. One common clinical condition suggestive of interactions between circadian rhythms and metabolism in humans is that of shift work. Numerous reports have indicated that shift workers have a higher incidence of diabetes, obesity, and cardiovascular events (1, 87), although the mechanism underlying this association is uncertain. Scheer et al. recently tested the impact of forced circadian misalignment (a simulation of shift work) on neuroendocrine control of glucose metabolism and energetics (88). In participants subjected to circadian misalignment, the investigators observed hypoleptinemia, insulin resistance, inverted cortisol rhythms, and increased blood pressure (88). It is also interesting to note that patients with diabetes exhibit dampened amplitude of rhythms of glucose tolerance and insulin secretion (89); thus the relationship between circadian disruption and metabolic pathologies appears to be bidirectional in humans, suggesting that circadian disruption may lead to a vicious cycle and contribute to augmentation and progression of metabolic disease.
Direct genetic evidence in humans has linked the molecular clock with sleep (90, 91) through the positional cloning of mutations causing familial advanced sleep phase syndrome, which is characterized by early sleep onset and awakening (92). In the general population, observational studies have also found that short sleep, sleep deprivation, and poor sleep quality are associated with diabetes, metabolic syndrome (82, 93), hypoleptinemia, increased appetite, and obesity (94, 95). A recent study showed that sleep duration correlates with the magnitude of weight loss as fat in response to caloric restriction; short sleepers appear to have more difficulty losing fat compared to long sleepers despite similar amount of weight loss (96). Narcolepsy, a sleep disorder in which patients present with extreme daytime sleepiness due to loss of hypocretin-producing neurons (97, 98), has been associated with elevated BMI (99) and increased incidence of obesity (100, 101). Night eating syndrome (NES) is another instance in which disrupted rhythmic patterns of sleep and eating correlate with altered metabolism (102) and obesity (103). Patients with NES consume significantly more of their daily energy intake at night, although their total daily food intake is similar to that of control subjects (104, 105). They also have abnormal rhythms of metabolic hormones, including decreased nocturnal rise in leptin, a phase shift in insulin, cortisol, and ghrelin, and inverted 24-hour rhythms of blood glucose (104, 106). Interestingly, the nocturnal pattern of eating observed in NES patients is reminiscent of feeding alterations in the Clock mutant mouse. These animals exhibit increased feeding during the normal sleep period together with increased susceptibility to diet-induced obesity (107). A major goal is to determine whether the adverse metabolic consequences of sleep loss (and accompanying feeding alterations) are due to the disrupted circadian rhythms per se, to the altered sleep, or to some combination of the two. Nonetheless, the above observations in humans demonstrate that synchronization of feeding/fasting and active/rest periods with the environmental light/dark cycle influences body weight constancy.0 -
Sooo what about us night shift workers that basically live at night. I Must be pretty screwed since that's when I eat ALL the calories!
I've never watched his show so I don't have first hand experience of his insanity but he sounds like an idiot.0 -
Yes it will likely negatively impact you in the long run given the study I posted above.0
-
change will likely to may.
Also, it's a review of published, existing data, and not a study. What I missed from it, was discussion of testing on humans. I'd take it with a grain of salt at that point.
There might be a correlation, there might not.0 -

Nope. I work nights, and have worked nights for the past 4 years. I sleep during the day. Other than being over weight (which I have successfully lost in the past) I am healthy. This is a load of crap.0 -
Oh really. Well I have dinner around 9-10pm most days but have been unsuccessful w/putting on a few lbs so maybe he can tell me what I'm doing wrong, lol.0

I skimmed the article but this doesn't account for a calorie deficit I don't think so it doesn't apply. Are they magic calories at night? It may affect digestion and metabolic syndrome (ie. your health) in a sustained regimen but you can't get blood from a stone.

Its a very basic statistics error to confuse correlation with causation. Eating calories at night and weight gain do correlate, but not because eating calories at night is the cause - just because many people who do that probably have other habits that are the cause (overeating, eating junk, etc).
I once read this study that mothers who eat blueberries during pregnancy were X times as likely to have a healthy child as mothers who dont. It's not that eating blueberries during pregnancy magically protect your child from sickness for their life, but probably the type of mother that has the financial means and makes the healthy decision to eat fresh fruits during pregnancy is probably also the type of mother that would provide their child with similar nutrition throughout childhood. And that is what makes the kid healthy.0 -

Oh, you guys are so darned mean talking bad about Dr. Oz!
No really. Just wanted to stir things up.

Yes. More shark attacks happen on the beach when the ice cream stands are open (in the summer).synchrony7 wrote: »Its a very basic statistics error to confuse correlation with causation.

I guess to reduce shark attacks we should close the ice cream and banana stands...

He is not correct but I would never eat a hugh meal and then go to bed. Every person is different so it may be true for one person but not all. I can not eat for two hours before bed are I gain. So I know my limits and that is what I stick to. I refuse to watch him. He has no clue.0

I don't need science for proof. I eat and eat and eat, take raspberry ketones, watch soaps day and lose weight and build muscle. That's all the proof I need. Lol at those who exercise and eat healthy.

This may be true, but they don't look better than me naked. And that's all that matters.

You've seen me naked? Was that you rustling my bushes last night? Mirin my delts??

While I agree he is not correct on a number of things, many posters are complaining that he promotes nutritional supplements that he actually doesn't. He did an entire episode {one of the few I've actually seen} talking about how companies are using his picture and name illegally to promote their products. Green coffee bean extract being one of the many. He actually asked viewers to send photos and details to the show when they come across these promotions in the stores so he can contact the store/company and take legal action. Just wanted to help set the record straight on one aspect of this thread.
