    Fasting has been steadily growing in popularity & a lot of people have questions about extended longer duration fasting. Unlike intermittent fasting this will typically involve not eating for a couple days. And most people immediately dismiss this as a viable option for Fat Loss & weight loss because there are so many myths surrounding this topic. People are worried about losing their muscle mass, they're worried about slowing down their metabolism, & they're worried about their health & well-being in general. So in today's video I want to go over exactly what will happen to your body if you don't eat anything for 7 days straight. If you're looking to burn some fat lose some weight or if you're just looking to try an extended fast I highly recommend you stay with me through this video because I can tell you exactly what to expect & help settle the myths & doubts in your mind about a longer-term fast. First off let me start by saying that you shouldn't just jump into a 7 day long fast without first getting used to shorter fasting intervals like intermittent fasting, the warrior diet, and the one meal a day diet. I recommend you first try to fast for only two days however, even if you did do a 7 day fast contrary to what a lot of you may think you're not going to just drop dead. Your body is very good at conserving energy when it doesn't have access to food. This is how Ghandi at 74 years old was able to go on a 21 day hunger strike & not starve to death. When you fast for an extended duration your body will mostly use stored body fat for energy. And even though Ghandi was already pretty lean before his fast he was able to complete all 21 days. For most of us we consider a normal diet as one in which we eat every couple hours. However, before the invention of things like farming & refrigeration our distant ancestors would experience long periods of fasting followed by periods of feeding when food became available. So most people are actually very capable of fasting for 5 to ten days without much of a problem even though a lot of people think they'll practically die from starvation just by just skipping a meal or two. Just to drive this point home even further there was study conducted by researchers from a University in Scotland that was published in 1973. In this study an extremely obese 27 year old man fasted for 382 days. And believe it or not he didn't drop dead. He actually went from weighing 456 pounds............ to 180 pounds. Such a long fast could obviously only be achieved under the supervision of doctors with the use of vitamin supplements like yeast, sodium, & potassium, but the amazing thing is that the researchers followed this man for 5 years after his fast ended & he managed to maintain his weight.... never crossing back above 200 pounds again. Studies like this completely disprove the myth that your metabolism will shutdown & won't ever function normally again just because you don't eat every couple hours or every couple days for that matter. A 7 day fast is definitely something that you can work up to overtime, so what should you expect to happen to your body over the course of one week of fasting. Well about 6 hours after your start the fast your body will completely finish digesting food & breaking down glycogen into glucose. That glucose is primarily used by your body for energy & even though it can last for up to 24 to 72 hours it will typically be depleted after just 6 hours. So for most people that's when you can expect sudden hunger pangs & food cravings to start kicking in. Also in this initial phase your mood will change because your body is still used to getting it's energy from glucose, so you can expect to be a little "hangry" in the beginning. These intense hunger pangs that can also come with the feeling of dizziness, weakness, & nausea, diminish after the first 2 days for women & can take 3 days for men. If you can overcome these first

    im was 514 lbs (6'4") 10 days ago, now im 499 with the one meal a day (at the same time I cut all creamer in offee and go straight black and get my sweets from diet caf free dr pepper). I can confirm the first 2-3 days of being super hungry but after that you dont want to eat. and that one meal I can barely eat anything. super small proportions. im goal is 354 by end of 2020.

    For a marriage couple, make sure that your wife do the fast along with you, or she'll start teasing you with yummy food they made or buy. The worst part is, they never buy/make the delicious food before when im not fasting

    ** Excellent video but I disagree with you on ONE item, and that’s where you say “consult with a doctor first.” I’ve been in pharmaceutical sales for 20 years and sold to every type of doctor and let me tell you this, they don’t know a SINGLE FUCKING THING about nutrition, overall health, nutrients , etc. So, consult with your dietician or nutritionist but not at MD!

    So I just finished my 7th day of fast, just drinking water. The entire experience was ok and very effective. I lost 14 pounds! 2 pounds per day. First 4 days were good, quite allot of energy, no hunger, no pain. From day 5 I started experiencing very painful nausea, heartburn and the last day almost vomiting. The last day I had to buy pills for decreasing acid in my stomach because it was truly bad. But I lost weight which was my main intention :) Just be careful, its really good to start slow and just for 2-3 days :)

  • Allie Tracy

    I just naturally fast because of my sleep schedule and my hunger levels. I guess because I’ve been eating healthy for a while and intermittently fasting for a while too. I eat maybe one full meal (not unhealthy!) and then I won’t eat for like two days and then repeat. Sometimes I’ll do a longer fast the longest I’ve done is four days. Since I’ve started doing this I’ve lost a lot of weight. Probably about 55 pounds. Since I’ve started doing this I don’t know why or if it’s even a thing but the sight of junk food makes me want to throwwww up. Sweets, greasy food, anything like that makes me nauseous I can’t even think about eating it. After fasting I just want a fat ass salad and some water😂

      long periodes of fasting is generally a bad idea while you are that young, however doing 24-48 hours would probaly be just fine.
