After watching Fat Fiction, this has got me wondering. Specifically the part where they mention protein is essential and, after that, fuel your body with either carbs and/or fats. I’ve always calculated TDEE and then assign percentages to protein, fats, and...
This might be a lengthy post. But bear with me, please. I know a bit about nutrition and diet; however, I don't understand body consumption of energy. 1) They say that carbs are the body's fuel, which means carbs are essential. But...
If you're replacing your coffee with them (and you're taking in the same amount of caffiene) then what's so bad about energy drinks?
Just what the title says. What foods help improve energy (reduce drowsiness, maybe improve strength and alertness)? What foods do you avoid?
It seems to be common wisdom that having carbs as the main calorie source is important, and while I do share that, I want to understand *why* exactly. I wouldn't want to oversimplify an issue I am not an expert...
Sorry that this is a really stupid question, but I'm kinda confused. So I'm trying to learn more about macronutrients and bodybuilding/nutrition and I came across a question about protein. From what I found, protein is primarily used for muscle...
Hi, I’m about to start back into the 40hr a week grind after taking a couple years off. Coffee and caffeinated tea give me the jitters after a few days of taking either, and then I usually crash with a significant headache/migraine...
When you exceed a certain number of hours of fasting, around 20 hours, your body starts producing something called Reverse T3, which is used to reduce metabolism. To understand what reverse T3 is, we need to know what metabolism is...
I’ve been fasting for quite some time, but I’ve been struggling recently with fatigue. What hour does energy really kick in for you? 18? 20? More? I’m wondering if I need to lengthen my fasts. I eat relatively balanced and healthy,...
Carbs digest faster than fats. But is that because carbs take less energy to digest? Or because the body goes into overdrive like a high intensity workout to digest them quicker? Maybe fats take just as much energy, but that energy...
I watched the game changers documentary and im curious about the plant based diet. Has anyone tried it? If so did any change happen? Was your physical performance better or worse? Im very curious.
Is this possible?
38 M, very low body fat stores to start with (not doing this for weight reasons) Previous best was a 100hr dry fast, with some 72 and 96 water or dry fasts mixed in. Nothing more than a day since...
How do they manage to still perform well in the animal kingdom having enough strength to hunt, catch and kill their prey? When I go into dry fasting mode I’d be lucky to even walk half the distance I walk...
Caffeine doesn't do the trick to me and i always feel tired even if i sleep enough. Edit: thanks everyone for your advice!! Im going to look into some of the things you recommended.
I want to hear some opinions on this one, tell me about your experience... Are there energy drinks that you can have during fasting that are low/no calorie that don't technically break your fast? I have been doing a lot of reading...
Coffee upsets my stomach too much. What else during a fast can I drink? Especially before workouts
Im on day 4 of my 6 days waterfast, and what i have noticed is that my energy levels and hunger goes intensely up and down during the day. Like today i felt like death in the morning. I was...
Started at 260 lbs, 6’ 2. My goal is 210; then, depending on how I feel and look, possibly 190. I don’t “look” “fat” even now (I have strong legs and a naturally good shape, and lots of meat under...
I’m in the military and would like to lose roughly 20-30lbs. I work out every morning (mon-fri) and sometimes when I get off work I’ll go to the gym for weights. If I drink a energy drink it’s a monster...
Hey there, I think it's quite safe to say: * Fats, of all macro nutrients, have the highest energy density. Decent amounts will result in unreasonable amount of energy intake and potential weight gain * Saturated fat rich foods are prone to increase...
Now this may be an unpopular opinion, or not, but either way; I hate working out whilst in a fast. I tend to do 18/6 and workout just before I eat ( typically around 4pm) I'm used to doing longer fast,...
I have been on semen retention and plan to stay celibate until I achieve my life goals. Obviously the 3 most prolific ways of obtaining more life force energy is through semen retention, fasting and meditation. But does dry fasting...
I’m jumping in the train… finally. I’ve read many conflicting forums about surcharges free energy drinks and if can throw the body out of fasting. What are opinions on this? Will this destroy a fast? I’m really...
So isn't it optimal to eat bugs and plants given they are primary consumers and producers
So I know a lot of you have lots of info around on fasting. In particular what I'm looking for relates to respiratory quotient (RQ) and fasting. So I think most of us are generally aware of the \~3 day...
I've been doing intermittent fasting again recently. Basically, what I do is just eat in the morning before my workout and that's it. But now I want to take things a bit further and go on a full water fast....
As the title suggests I am wondering why they add so many vitamins and supplements to energy drinks. I am having a hard time finding the exact science on it. Is it to curb the crash or just to increase...
Specifically Reign Body Fuel. I know artificial sweeteners might trigger insulin response, I wanna know if any of you experts out there knows if it might affect my fasted state, especially when it comes to ketosis and how long this...
Hey everyone, hope you’re all well. I had a few quick questions regarding nutrition that I was hoping someone could enlighten me on. First of all, what exactly causes one to gain weight? The way I’ve heard it, if you consume...
I'm on my second 96 hour fast.. halfway through. First time wasn't as bad as I thought it would be. Had mild hunger, but four days was doable. I keep reading about higher energy.. I'm able...
This is an extract from Dr Filonov's book '20 Questions and Answers about Dry Fasting' This book has a wealth of information and I highly recommend purchasing it from [https://dryfasting.info/](https://dryfasting.info/) ​ What are the advantages of dry fasting compared to water fasting? In a...
I have just finished reading the Obesity code by Jason Fung and have a question regarding CiCo. I know CiCo is a somewhat controversial and confusing topic but I can’t seem to find any answers for this question I have...
And if so, why are “starvation diets” deemed unhealthy for weight loss? Does your body “live off of itself?” During a fast? Is “metabolism” a myth in weight loss?
Dry fasting is the antithesis of inflammation. Is dry fasting the epitome of living longer? Are there any centenarians who currently practice dry fasting? The exact and specific search, "centenarian dry fasting," provides 0 results...
Just wondering which is better fat vs carb for immediate energy (say 1-6 hrs) and if they differ in terms of thinking clearer/could perform better physically?
I just completeed my first phoenix protocol 7 day (soft) dry fast. It was a humbling experience made me appreciate water in a way I never thought of. I lost 27 pounds in that time frame (186 down to 159,...
I am wondering if someone could explain the way the body uses protein when it comes to different bodily needs. If one eats exclusively protein, will their body prioritise the use of protein for energy rather than muscle protein synthesis?...
**FINAL UPDATE:** Made it 19 days! I really really wanted to go till 21-25 but the nausea just got to be waaaaay too bad after Day 14 or so. No matter how much I chug electrolyte water I was perpetually...
Imagine i eat 100g of carbs OR 100g of fat. Carbs: 100g = 400 calories Fats: 100g = 900 calories Calorie difference: 500 calories Mass difference: 0g I have 3 same questions worded differently: 1. Where does the gain/loss in...
The idea of calories and balance between intake and output has sound logic. While learning about the topic I came across the Atwater system. I was expecting (naively) that measuring calories was something we deduct from how the body utilises...
Couple of questions about that 'fasting high' I hear people talking about so much... 1. First of all, what's the technical term for it? I've heard it called 'deep ketosis' here but wasn't sure what it's really supposed to be called. 2....
I had 2 RMR tests done to see how my metabolism changed. Figured I'd post here! 26M/5'11"/SW250/CW205/GW170 The tests were taken around the same time of the day, in the morning. Test 1 was done on a Monday and I had...
How do you guys have enough energy when dry fasting? Or do you just deal with the low energy the whole fast?
I looked around for posts about this, but most revolve around the likelihood of overeating when drunk, alcohol calories on top of daily calories, more likely to spend a day doing nothing, etc. Alcohol does hinder sleep and workout quality, may...
I’m a teacher, and In the summer when I’m not working I find it a lot easier to go all day without eating (obviously cus I’m not exerting as much energy) but when I work I’m moving around a lot,...
Excluding the thermogenic effect of food, do we absorb all of the calories we eat as said on the package or is soke energy lost es. with feces. To my knowledge no energy is transferred with 100% efficiency so I...

Kind of a dumb question but what are the harmful biological side effects of energy drinks/artificial sweeteners? Bang and Alani Nu have 0-15 calories and 0 sugar per can. Other than messing up sleep schedule, what harmful things do they...
Hey guys! Do you think one sugar free monster energy drink a day is bad? I’m a medical assistant and nursing student, so it really helps me get through multiple 12 hour shifts a week and school. Pretty much everyone I...

I'm wondering what the opinions are, or the science behind these new energy drinks. Monsters and red bulls all have so many chemicals listed in them. This has many vitamins listed, but also has sucralose. Of course, there are artificial...
Okay, I'm super overweight. I'm 4'11 and weigh almost 270lbs (122kg). So I know I have all this energy stored in my body, and intermittent fasting will cause my body to start utilizing that fat for energy. That's why my...

For further info, I had an amazing experience with omad but I wasn't exercising at the time, now I am. What if I need the energy for the night e.g. spinning
In simplistic terms, how does IF work? I have always been told, and a quick google search confirms, that if you don't eat your body will store your fat cells because it thinks it's being starved. So how does...
I'm not entirely sure how to phrase this question, but is food more 'useful' for the body when consumed in the morning or afternoon? The reason this might be true, is that the energy (calories) which are consumed can be...
is it because of malnutrition and if we eat too little, we do not get enough nutrients? or is it the calories in themselves are important even if they have little nutritional value?
I've been looking through books and can't seem to find my answer anywhere. In glucose storage, is the ratio for preference of glucose storage (e.g. as fats, or glycogen) different to the ratio of how it is retrieved from different...

Is 90 calories of beer going to have the same dietary impact, i.e. fat production, as 90 calories of whole wheat bread?

I'm a 20 year old male who does 20/4 IF with the goal of fat reduction. Energy drinks and in particular Bangs are my biggest vice. While it seems pretty clear that they do affect your fast, I haven't quite...
I’m just over a week into 16:8 fasting and my body has finally adjusted to not eating as much so I’m hungry less (yay).. but I’m tiiiiired, and I definitely haven’t noticed a huge boost in mental clarity or concentration...
Does having a zero calorie BANG energy drink break fast?
I know it’s expected to have more energy with IF (I had the same when I used to be keto), but does anyone else find they have a stupidly high level? Like I’m getting so much done and then finding the...
I started 16/8 this week. I’m trying to slim down a bit. I’m not overweight by any means but would like a trimmer figure. I do carpentry/ labor and I feel like I’m dying to get to my 10-6window. I take...

Not doing this for weight loss.
Is there any other source of energy that can be consumed while fasting besides coffee?
So I’ve recently started IF (16:8) and am fine with it (only missing my milky morning coffee badly). Noticed that I feel better than I usually do first thing in the morning and in general have more energy and focus, which...
Hi, will sugar free energy drinks mess up my omad? I drink black coffee and lemon water. Energy drinks are super convenient but I know they aren't great. Anyway I don't care if you hate them. I just want to...

I normally drink a Bang energy drink in the morning but i guess these break a fast due to the BCAAs. Does anyone know of something similar that will allow me to fast?

I know how that sounds, but its a serious question. Almost everyone I know says they cant operate without a coffee in the morning or throughout the day, and that it helps them wake up. For me, all it does...
Everyone who sees me drink it says it's bad for you. Cancer in a can, your heart's gonna stop, yadda yadda. But how bad is it really? From a cursory Google search I did, the consensus seems to be that the...
I can’t even pronounce half the ingredients listed on energy drinks, but what are some key ingredients to avoid?
Hi I'm curious If I'm allowed to have a sugar free monster energy on a 24 hour fast when the goal is weight loss, I also hate any type of coffee and tea . I checked my fitness pal...
I have been experiencing low energy recently, sometimes I cannot even get out of bed, but I have read on other subreddits with people with the same issue recommend electrolyte pills. Should I try it?
This might sound like a dumb question, but does ”metabolism” refer to your BMR/RMR or TDEE? The reason I’m asking is because I often see people use it interchangeably with both BMR/RMR and TDEE.
I'm (48M) on day three of a my journey into IF doing 18/6. I just have a question that others will have gained knowledge as they've progressed. I try to work out before I go to work. Which means it's...
