Intermittent Fasting, Yes it Works

I also found the article interesting. I listen to Dr. Peter Attia's podcast and have heard him mention he does a fast once a quarter, I think he does longer fasts (4?) days. I'm on a Keto Diet and find hunger is not a problem, I have been busy the last 2 days and and only averaged about 725 calories, and decided to fast today. It will be my first fast, I may go two days, but I'll wait and see how I feel tomorrow.
 
I'm questioning who wrote the rules that in order to healthy you have to eat 3 meals/day scattered evenly throughout the day and a snack to reward yourself at night? This was the way I was taught, to be healthy. And the food pyramid is pretty ridiculous and has changed ~100 times at the whim of nutritionists and medical community.

I continue to follow the 16:8 eating time restriction diet (I guess that's the correct term), for the most part. Am at my best weight, sleep well and remain active mentally and physically. Follow, vegetable, fruit diet with some meat/fish and pasta too. It seems so simple.


2019-decabo.pdf Sengsational posted the scientific background as to why it works and why it makes sense. Thanks.

Even worse than that is the nutritional information given to type II diabetics. Be a grazer. Eat many small meals throughout the day. And make sure they contain plenty of fruits and vegetable and healthy whole grains. No wonder we have a diabetes epidemic. When I reversed that advice (except for the lots of veggies part) is when the diabetes went away.

I believe it was all about blood sugar control and attempting to keep blood sugar even for diabetics, and not have spikes. In fact I think the fad came to suggest 6 small meals spaced out during the day. But, as usual, the medical/nutrition community totally missed the boat on this one because eating often causes insulin levels to stay high which is very unhealthy and can in fact cause metabolic disease. And, as usual, I doubt there was scientific evidence to back up the multiple small meals suggestion. No clinical trials. It was just supposedly “common sense”.
 
Like drinking 8 glasses of water a day. I've never been able to find a single scientific reason for that recommendation. The only remotely likely explanation is that it keeps you feeling fuller, so maybe you won't eat as much. But no science.
 
DW and I have accidentally falling into intermittent fasting during this COVID-19 crisis.

DW is hell bent on starting with 15 days of social isolation, so what we had in the fridge and cupboards is what we had. We did stock up a little bit in late Feb after I read some of the prepper threads here. But not a lot.

The upshot is we are monitoring our supplies closely and simply not eating as much as we used to. I hear others are going into "crisis eating". I get it. Since we've not been to the store, we can't.

So with stretching our supplies, we naturally fell into skipping the nightly snack, and then eating a much later breakfast. Basically, we're fasting 16 to 18 hours per day.

We both lost a few pounds this first week. We'll see if there are other effects later. I'm also suffering through nail biting withdrawal so my attitude isn't exactly great. I'm hoping it improves. :)
 
Fasting eliminates senescent cells too. Those are "old" cells, so you actually appear, on a molecular level, "younger". It's a good time to be a few years younger ;)

Autophagy, no? Wonderful discovery.

Apparently also triggered by very low insulin levels, so possible just from keto diet.
 
We've been remarking on how easy it is to maintain our LCHF/IF regime. DW did stock up on a few things like macaroni noodles and beans, things that will last if the SHTF. But our plan is to donate that to food banks after this is all over. We'd only eat it at last resort. Our fresh vegetables are currently turning into just vegetables, as we haven't been to the store in a week. They aren't pretty, but you can still eat them. But we also have a lot of frozen veggies, enough for another couple of weeks. Because, you're right, IF does reduce the amount of food/calories you eat, making the supplies stretch further.

Our tomato plant is starting to produce red cherry tomatoes, had our first two yesterday. Our lettuce will be harvestable in a week or two. Other plants are farther behind, but coming along. This is one advantage to being in FL. And DW was brilliant in having us start planting so early in the cycle.

I must say, the main reason we've been able to stick with it so easily is that we don't have any of the bad stuff in the house to be tempting us during our depressed moments. Poor DD, who is also doing IF/LC eating, has two kids, and her house is full of bread and cookies and Fruitie Pootie cereal, or whatever they call it. So far she's hanging tough, but last night when they all had spaghetti and she just had the sauce and a salad must have been hard.
 
Partnering with IF, we're watching fructose intake. I love pears, this is hard. Now focusing on berries with breakfast. Starting to buy red peppers, slice up and snack on with hummus. Since our mail meal is early @ 1 pm and we're watching more Netflix during the day we're air popping popcorn. No salt, trying without butter. Just to snack before 2-3 pm when fast starts.
 
We also stocked up on some lentils and beans and OMG one large bag of basmati rice from Costco, but that was in case we had to feed my elderly DF which would really be a SHTF situation.

The freezers are full of all sorts of different kinds of meat, poultry, fish, plus frozen veggies.

Our main challenge has been eggs. I scored 3 more doz recently, so we’re enjoying a few more 2 egg per person breakfasts.
 
It is NOT working for us.

We initially went on 16/8 around Jan 1st & soon changed to 18/6. With the Gym closed now we walk a couple miles a day & I try to maintain 1500 Cal daily on Fitness Pal. I have Lunch at 1 PM & finish my Supper by 7 PM.
I am 64, 5'5", a diabetic(Normal A1C of 5.5), have osteoporosis & started out at 160 lbs, a egg eating vegetarian & on a Premier protein(30 gm) drink daily. I got down to 154 initially & am back up to 158 lbs now.

The Metrics have not budged that much on a Fitness Scale & although not all of them I understand, they presently are -

BMI is around 26-27,
Body Water 23.5,
Body Fat % 23.5
Skeletal Muscle 49.4,
BMR 154.7 k cal,
Fat free wt 120.4 lbs,
Visceral Fat 9.0 lbs,
Skeletal Muscle 114.2 lbs,
Bone Mass 6 lb,
Metabolic age 66

I am not giving up (yet) but it is getting a little disappointing.

They say muscle weighs more than Fat, but I am not doing any weights(at the Gym) for past 1 month or see any body muscle changes on me.
Maybe I am not eating enough, & body is going in Starvation Mode. I do not know

So, what gives ?? What am I doing wrong ?

Any & all suggestions are welcome please with thank you in advance.
 
Just to add too much information, another life extender, Metformin.
It also inhibits mTOR.
https://www.nature.com/articles/cddis201213

Don't for a moment think I understand very much in these articles, but I'm trying.
Someone on this site mentioned Peter Attia, he's very interesting.
btw he takes Metformin although he mentions benefits of the drug, has not specified why he takes, at least the small percentage of what I have listened to.
https://peterattiamd.com/podcast/
At the top find a list of all his podcasts in order.


A bit of an update first, I've been on a Keto diet for 8 weeks, I did blood tests at 7 weeks and just now saw my doc. I had blood test from 6-19 and 3-20. Fantastic changes in 7 weeks, LDL 106 to 54, Triglycerides 397 to 82, Total Cholesterol 195 to 109, and my HDL went up from 36 to 39.
And I lost 19 lbs
EDIT: to add, I am also sticking with an 8/16 eating schedule, Noon to 8pm.


Doc said, your doing the right thing, keep doing it.
I had been thinking about asking him about prescribing the above quoted Metformin, but I had kind of shrunk back from it, but in our talk back and forth, there was a natural opening to ask, "What do you think of Metformin?" His reply was, "I think it's a great drug", "I said would you put me on it?" He said, "sure", and then gave my a list of what he takes. He added Resveratrol, MNM and Tumeric. I ask him about whether MNM or NR is better and he didn't have any opinion and put both on the list to let me decide. I read the NR is easier for the cells to use.
If interested in Metformin, studies have shown reduction of Alzheimers, CVD, Inflammation, aging, cancer, and Arteriosclerosis.
My doc is following what David Sinclair recommends.

I search all my information from Dr. Peter Attia. This video is a Q & A discussion with Dr. Attia. He explains a lot about intermittent fasting and the body process. Very good information here and may help you!


 
I've been intermittent fasting for over 2 years. My typical eating schedule ends by 4 pm. Then resumes at 6:00-7:00 the next morning. There are times I eat later b/c of social situations. I just started listening to Dr. Peter Attia podcast "The Drive", suggested on this forum. So impressed with the in depth discussions on this podcast. Dr. Attia fasts on a regular basis.

-My energy level increased, a lot
-Weight loss and stayed off
-Digestion improved, drastically
-Yearly blood work excellent



Has anyone else tried this?

Yes and yes to all of the above. I started doing this in late January, fasting between dinner and lunch the next day, about 16 hours in total, and have lost 12 pounds to date. Am experiencing all of your bullet points as well, plus I'm really not hungry in between meals.

I haven't felt this good since hitting menopause five years ago. It feels great to be getting my swag back, and I see this as a permanent lifestyle change. Ten more pounds and I'll be back at my lean, mean weight .

Glad to hear it! I'll take my advantages a few steps further:


-Normal daily bowel movements :)) first time in my life!)

-Better sleep, more sound and wake up energetic
-I can eat Oberweis Ice Cream, as long as it's within eating window and I've lost 5 more lbs.

-My overall attitude has improved. I don't complain as much.:angel:
 
I started around the end of January. 211lbs. Today I was at 192. I have not been religious to any one time slot. First week 16/8 to 18/6. Then a couple of weeks at 20/4, then back to 18/6. I have found it easy to do. and I like the results so far. Real question is how easy is it to live on 16/8.

I am about 3 months + into a 16/8. I find it very easy. There have only been 2-3 occasions over that time period where it didn’t work because of social engagements or travel.

I haven’t changed my workouts or much else. I just don’t eat breakfast and I don’t eat after 7-8pm.

I would find that very easy. I have been doing 20/4 for 2 1/2 years. I eat a snack and one meal. Usually done eating by 3:30 or 4:00.

So obviously you have found that it doesn’t reduce your ability to workout at all?

Correct. That was an early concern of mine, but it was more of a mental block than a physical concern.

The first meal after a workout tastes really good though.

While I'm pleased it's all working for you, my main comment is "What the hell are you doing going to see a doctor for a non-emergency issue right now?" I can't imagine a better place to catch something than a doctor's waiting room, except for a hospital. Unless this was a video check in, in which case...never mind.

" I can't imagine a better place to catch something than a doctor's waiting room, except for a hospital."


Isn't that always true? Should we cancel all non emergency doctor visits during the flu season? I'm sure it would reduce deaths from flu.



We have 6 confirmed cases of Covid 19 in my county, pop. 185,000, less than 20 in the surrounding 4 counties. I think the docs office is very slow, there was no one in the waiting room. If there was, I would have waited outside. If the doctor thought it was a problem they would have cancelled
my appointment. I've had the appointment for 2 months.
 
DW had an appointment scheduled for 2 months for tomorrow. Her doctor cancelled it a week ago. And yes, I hate waiting rooms. I tend to check in, then wait in the hall until they call me.
