Here’s my newest FREE Meal Plan (High Protein Mediterranean with some Intermittent Fasting)- https://thomasdelauer.com/MediterraneanFasting/ Please enjoy it as a thank-you for subscribing to my channel and my newsletter!
Because they were probably paid to change there mind
Just eat like your farmer/rancher great grandparents did and move along. These guys come up with new things purely to stay relevant.
Bro I'm so confused
All idiots who don’t learn from history
Ill put my faith in Jesus, he liked fasting.. the experts told us 75 years ago fat was bad and sugar was ok.
You can't make money selling fitness coaching, food, energy/protein drinks, and supplements when people are fasting.
The greatest biohack of my life was and is daily IM fasting (5+ years now) and long term fasting 3+ days.
99% of fitness/health "influencers" are grifters.
Fasted for 3 days out of the week for 2 years and didn't lose muscle – only gained muscle and while on a ketogenic diet, you will only put on more muscle over time as long as you are lifting weights
Fasting is not a lifestyle, it’s a tool and a lot of people are overdoing it.
According to Dr. Fung, my go to on fasting, he put up a study RE ADF showing body fat went down after 14 days, lean muscle (fat-free mass) did not go down, but went up slightly. He has many videos on fasting and muscle loss. I totally disagree with these YT influencers. I’ve had, & continue to have, wonderful experiences w fasting. One 48hr fast, coming off it I always eat light, no veggies or fruits (they digest too fast to break a fast). I eat lightly meat, milk or cheese first meal. Last time I decided since I was eating meat, why not try carnivore for a few days. I was on it for 3 wks, felt great, got down to 19% body fat. I love fasting & believe it does great things for the body, such as consuming cancer cells, & other problematic or damaged cells. YMMV, best wishes to you.
I will ALWAYS fast. Extended, TRE, I don’t care about “experts” Attia promotes a scam AG1. Fasting is free, saved my life, and maintains my weight.
DONT LISTEN TO “EXPERTS” ON THE INTERNET. LISTEN TO YOUR BODY.
Okay… so the “experts” are going back from fasting is cool to eat as much protein all day like the 6 meal daily bodybuilder stuff? I don’t get it. They also said high protein was bad.
Like everything you need a balance no one person is correct
Basically eat enough protein.
I'm Muslim we have been fasting for thousands of years even present day, and we have the lowest cancer rate, obesity rate and live longer then most western countries especially the U.S
Attia is talking about 7-10 day fasts which I guarantee most in the comments are not prepared to do, nor want to. I feel like 2-3 days of fasting will have a negligible impact on muscle loss as long as you’re transitioning back into a high protein meal plan once the fast is complete
Their shared bias is they are all getting older, and their bodies require more protein to maintain function and muscle mass.
I think after losing 50 or 100 lbs and no longer needing to carry that weight one should lose lean mass as well.
They all agreed before that fasting was good🙄
Fasting got them to where they are so it worked… now they don’t need to fast as much. End of story
An Easy Way To Get 150+ Grams Of Protein
3 Eggs – 18 grams.
50 g of Egg Whites – 5 grams.
1 cup of Fairlife 2% Milk – 13 grams.
4 oz Ground Turkey – 20 grams.
1 ½ cups of Cottage Cheese – 16 grams.
2 Scoops of Protein Supplement – 31 grams.
3 Tbsps of Peanut Butter – 10 grams.
1 Packet of Safe Catch Tuna – 23 grams.
you can fast with without starving by eating foods that initiate autophagy and foods that support the process of autophagy,as per protein eat what you want protein boost metabolism,as per fruits and veg, the fatty acids in plants are long chain but when you microbiota digest the fiber the fatty acids from the plants become short chain which uncouples the mitocondria and you burn the fats in the mitocondria ,initiates mitogenisis,beiging of white fat for burning .WIN WIN! just boil green leafy veg to get rid of oxalites,same for beans.Mitocondrial Uncoupling i lost over 100 lbs,
Thank you very much for this very interesting material! I would argue that Intermittent Fasting and Fasting are 2 very different things metabolically, because of Growth Hormone production, among others. The input of almost all the doctors and athletes mentionned in the video is about intermittent fasting and not fasting, so the title should actually mention "Against Intermittent fasting" and not only "Against Fasting" in my opinion. In any case, really worth the watch.
all personal opinions
Fasting is a miracle with the right approach cycled properly. Dr Mindy Pelz does a great podcast where she goes over it in great detail particularly for women. It makes complete sense once you do it well but not necessarily for everyone of course.
Weird, one of the most effective ways to cure cancer is fasting. Now all of the "experts" are saying, stop fasting. If you are eating animal based, you're getting enough protein.
Need to cut out the excessive supplementing of real food with whey BS and Creatine.
They're missing many important biological aspects, only focused on muscle mass. You need muscle mass, but not too much of it.
so fast but take a bit of protein
'experts'
Two things can be true at once. Fasting can express longevity genes, and not eating protein frequently is incongruent with optimal muscle growth.
Just add protein in the fasting window .. simple as that really … keep it to the correct grams per day … thank god we have biltong a national treasure …
They are warning against it because they have been told and paid to go against it, because too many, as in WAYYYY TOOOO MANY People are getting healthy and getting off of their meds/poisons.
Every cardiologist has a different opinion l don't know what to believe anymore!!!!!!!!
Do not fast, it is bad for the big food and pharma industry. 😂 These people who changed their minds problably received payment from the above mentioned.
Fasting is wrong because they wanna be edgy and different.
The way you presented this video was very misleading. NONE of the experts here are "against" fasting, they are simply adding qualifiers to how and how long and why one does fasting.
Diets have just become another part of pop culture. These “experts”
are sell outs
Man I don't think anyone knows anything I swear it doesn't need to be this complicated
Still waiting for them to say that they don’t think fasting is beneficial
Still waiting for them to say that they don’t think fasting is beneficial
99.9% chance if you dig into their finances you'll find they are getting money in some form or fashion from big pharma or big food companies.
Well it might not be a strictly scientific way of judging the matter and it isn't isolating the variables but Peter Attia and Tim Ferris have both been hardcore fasters/keto adherents at points in time and they both have awesome skin for their age. I am disappointed with Rhonda Patrick to extrapolate missing breakfast being a problem into fasting as a general principle. The processes such as autophagy and the production of stem cells that are induced by periodic fasts seem to me to be worth a few days off protein, not that I know but surely muscle mass doesn't atrophy that quickly to allow for some periodic fasting. I can't understand why these highly analytical intelligent people who generally look at nuance and detail seem to be conflating regular daily intermittent fasting with 'fasting' as a general principle in whatever form – surely they are all talking about daily 'intermittent fasting' but just using the word 'fasting.' Tommy Wood seems to be the only one who differentiates between 'intermittent fasting' and less regular more prolongued fasts. Perter Attia and Rhonda Patrick really disappoint me on this matter (maybe giving up fasting has affected their brain function – and what use is a body wthout a brain (a pain in the arse I would think – imagine an immensly strong dementia patient…..)
Well, THE SAD is more stressful on the body
Sorry Fasting is great for me!!!!
I don’t care what they say 🤷🏻♀️
Who is paying them to say this?
