Fasting

Hi again, Jason Fung, intermittent fasting and "The Obesity Code". He has numerous videos on YouTube and his website to boot.2

Yes.0

Again, Jason Fung. Fewer calories is failed science perpetuated by ignorance and greed. Doomed to fail. Think biggest loser. They always gain it back
The contestants on Biggest Loser gain the weight back because they aren't taught how to make sustainable changes that last. If intermittent fasting works for you, that's because you're still eating fewer calories. Not a failed science.6 -
No.0

No, it really is failed science. Hundred plus years of research to prove it too.0

pushy huh2

You are confusing caloric restriction with fasting.0
-
Educate yourself. Google Dr Jason Fung.1

Don't need to! Dr Fung claims you can cure diabetes. Hogwash.2

The physiological effects of fasting and a that of caloric restriction is verifiably different. I could go on and on. But I would rather you folks who stand upon the "pulpit" of caloric restriction as primary, CRAP, do you due diligence and look at the science. This do it as well as many others present and past are spot on.1

You are confusing caloric restriction with fasting.
nope,Im not confusing anything. most people when they fast eat less,hence caloric deficit. if you fasted for 24 hrs with no food,youd still be in a deficit,although I am sure there are some who could eat in maintenance or a surplus during a fast(depending on the type). and fung is a quack2 -
Not eating is fasting. That isn't caloric reduction. That is not eating. The net effect may or may not be a reduction in total caloric intake upon the cease fast.0

There are many types of fasting,you need to do some research. someone above mentioned the types of fasting.fasting means no eating for a period of time(you got that). I dont eat for 16 hrs and then I eat in an 8 hr window,or 18:6(18hrs/6hr window). so I am still fasting and I am still in a caloric deficit because I make sure I get my calories I need in those windows of time.
if you did the type of fasting where you dont eat for 24 hrs and then eat the next day and repeat,you can make sure doing so that you are still in a caloric deficit or not. I said that its possible a person could eat maintenance calories or even a surplus in that window of time. but for most of us who fast we are still in a deficit.3 -
Touché, but it isn't the reduction of calories that is the mechanism of weight lose when fasting. It the hormonal shift of insulin in repsonse to depleted glycogen stores that ultimate precipitates the use fat as the energy source in the absence of sugar. It isn't the restriction of calories. Numerous studies will and do support this as well. At excess caloric intake, and fasting still results in weight lose, to say that it isn't the reduction of calories that is the primary mechanism.0

You do understand that fasting means taking in no calories during a certain time frame, which is just one way of eating fewer calories overall. So Jason Fung condemns eating fewer calories and promotes a method that causes people to eat fewer calories.11 -

Let's say in a 24 hour period my body needs 2,500 calories. If I eat once per day and I eat 3,000 calories what would happen long term? You are saying that eating an extra 500 calories won't matter because I didn't eat for 23 hours. Where do the extra 500 calories go?9 -
Again, there are numerous physiological responses that take place and are necessarily paramount for the burning of fat and the sparing of other bodily tissues that occur when fasting. It isn't the reduction of calories that spurs this adaptive response either.1

Okay, but if you eat 3,000 calories in one sitting you will use a small portion that is immediately needed and store the rest as fat. Then over the next 23 hours you'll burn some of the fat you just stored, except those extra calories that went above your energy needs. All of the responses you are thinking of happen to people who eat 2, 3, or even 6 meals per day. Your BMR does increase slightly at the 16 hour mark, but not enough to negate the extra 500 calories day after day.7 -
And if you are going to start blaming insulin you need to stop and look into ALL the things insulin does in the body.7

Well, if you permit me some leeway here and forgo lengthy discourse on the physiological responses, the extra calories could be expended or retained. It depends on other factors not addressed yet. Really, check out DR Jason fung. He talks about all of this at length with ample scientific support0

I would be happy to do so friend.0

I know who he is and I have read his work. There's a bunch of gaps in there with no science in which he makes logic leaps, just like the one you posted about where the extra calories go. Extra calories don't just disappear, they're stored as fat. There are other claims he makes as to health benefits of fasting that are also proven health benefits of weight loss.
Eating one meal per day or eating every other day makes it very difficult for the majority of people to eat beyond their total daily energy needs. I think it's great when people find a way that makes it easy for them to stay within their calorie needs, whether it is one meal or eating every couple of hours. The benefits of fasting, especially as stated by Jason Fung, are overreaching.6 -
And there are still so many other physiological mechanisms not in play in that scenario as well.0

Such as what? You keep throwing out the vague term of physiological mechanisms. What specifically does the body do during the fasted state that would negate overeating by hundreds of calories?3 -
You are actually quite wrong about that too.0
-
Really? Why?
