    I have literally never read another post by the OP and was just trying to contribute what I know to the discussion. Honestly I am bored here in quarantine and thought maybe these forum discussions might be interesting to get back into. Apparently not.
    As I said I will refrain from posting. I don’t have the time or inclination to research the post history of every OP. 😊
    Have a lovely Sunday all.

    I would encourage you to do your own research on this. Many to most people will share their experiences and that's great! But it's just that...a nonmedical opinion. Research has suggested that there may be as much as a 6% increase in fat burning due to fasted cardio. Again, it's research in medical journals that could best answer your question.

    It's not that we disagree with the research, it's that the research says nothing about overall weight loss.

    For example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4242477/
    In conclusion, our findings indicate that body composition changes associated with aerobic exercise in conjunction with a hypocaloric diet are similar regardless whether or not an individual is fasted prior to training. Hence, those seeking to lose body fat conceivably can choose to train either before or after eating based on preference

    "The research" you linked is one study of 20 females - I wouldn't call that definitive. I posted one up thread that is a meta analysis but everyone seems to be ignoring that.
    I mean the OP asked if walking fasted (moderate exercise) would burn more fat than fed and the answer to that question is yes. I don't know why everyone is twisting themselves in knots to try to disprove it.
    Whether that has a significant impact on overall results is another matter. I think someone up thread posted that they walked fasted for months and gained weight. I have done moderate fasted cardio most mornings for the last 6-8 weeks and have lost 13 lbs. Both are anecdotes that don't really tell us anything. I also gave up alcohol, added sugar and bread so that is probably more relevant to my weight loss than fasted/not fasted cardio. Maybe if I had done cardio in the evenings I would have lost 12.75 lbs, who knows. I do it fasted in the mornings because that is what I prefer.

    That was me...and it does tell us something. It tells us that I have been in a calorie surplus for most of 2020 and put on 20 Lbs despite walking most mornings early in a fasted state...and you have been in a calorie deficit.

    I didn't see any context in his post - just a simple question. Which I tried to help him answer with the facts that I was aware of.

    From my view proceeding to interpret those facts for himwould be somewhat infantilizing as I assume he can read the information and interpret and use it in relation to his own goals.

    But if that type of response is not welcome here then consider me suitably admonished, I will refrain from responding in future.

    I think this is a fair point -- you answered the very technical point of the question, the rest of us are actually assuming the question was more like -- "will I lose weight faster doing fasted cardio."

    Exactly this, and (like you) I strongly believe the assumption was correct.

    People get confused about burning fat during exercise being somehow better for weight loss, but it's not, has nothing to do with it. I've actually had people warn me that running or exercising too vigorously hinders weight loss vs walking, because your heart rate gets outside the fat burning zone, which is another such misunderstanding.

    I suspect for OP, the relevant question is if he would burn more cals walking fasted vs not, and probably not. He might even burn fewer if he walked less time or slower because he wanted to eat or didn't feel as strong. (I don't think that's a major risk if he just had a specific goal to walk a certain distance or some such, but if he's just getting active again and finds himself getting tired by the end of the walk, it would be something to consider.)

    Have a lovely Sunday all.

    And on a different OP where several of us had not helped with similar questions - we'd be in the same boat and the info could indeed be very useful with no context given - so keep it coming.

    I was alluding to the same fact of what occurs during the exercise, with when it is a specific help.
    Because people do hear things they think are useful in all cases - so pointing out the actual use case can be helpful.
    Like some see the commercials and read very little and think they need to drink a big chocolate milk after their workout - no matter what that workout may be. Search the topics - they are there in the past.
    And they may really prefer to have that calorie room for something better, because that drink really isn't needed for their workout.

    But that info in some hands may not lead to much except disappointment, thinking more should have happened.
    At least that's the good thing on these minor nuances - not too much harm is going to come from it - merely wasted time and focus on things that really don't matter in the big picture. At least not yet.

    Inevitably it is eating at a deficit over time that will create weight loss. With that being said, I like fasted cardio. I will usually prefer a fasted run to any other one. Big fat however, if I were to run fasted and come home and overeat then no matter how great the run was the fasted cardio wouldn't have made a difference and would have been done in vain.

    Also and most importantly if you enjoy doing cardio fasted as opposed to not doing cardio in a fasted state, then ultimately, that is what matters most!
    I run/walk fasted each day (90 minutes) and then resistance train for about 30 minutes (one body part). I like training fasted because I don't worry about getting nauseous or feel like throwing up since I have no food in my stomach. Also, I don't feel hungry directly afterwards and can wait another few hours before eating.

    And yes there is good medical science to show that you may burn a higher percentage of fat for fuel in moderate to low cardio exercise, but if someone trained higher intensity for the same duration, they'd likely burn more overall fat calories in total.

    Incidentally, OP if you don't know it, you burn more fat calories overall at REST than any exercise regimen you do. It's actually part of your BMR. If you're NOT getting enough sleep, this can be impeded.

    I read the second paragraph a few times. I think I get it...

    Fasted cardio, part of the reason it works for me may also be added to the fact that I like getting out in the morning without breakfast first thing. I'm sure it's mixed with morning energy and not being weighed down by food. Today I packed a peanut butter and jelly sandwich, ran 3 miles, walked one mile to the playground and while my son played I did one minute of jumping jacks and walked around the playground, another minute of jumping jacks, walk, repeat process three more times and then walk the mile home. It felt amazing, unbelievably amazing!!! I didn't eat the sandwich until long after I got home. I love fasted running! Rarely will I eat before a run but if it's a long run, I run with fuel for the "in case."

    Sadly untrue, that is some pure bro-science your PT is telling you, I did not eat clean (whatever your interpretation of that is) and still lost weight at the rate I intended and met my macro requirements. I had KFC and some homemade chocolate cake interspersed with homemade meals cooked with some great big dirty carbs.

    Junk foods no good to me

    I am curious, you've been coming back and forth to the forums over the last couple of years, with the same sort of questions most of the time and seem determined to make weight loss more complicated than eating less and moving more.

    Your method will only work for you if you can stick to it long term, can you see yourself still "eating clean" and not eating "junk" food for the rest of your life? If you do, what's different this time?

    My diet plan changes when my body has adjusted to it so I'm eating a more balanced diet I can have a cheat meal once a week in a few years my goal is to be a bodybuilder so I'm working towards that

    "Clean" is subjective. And it's terminology that PT's use to get you to think it will lead to weight loss. You can eat "clean" and gain weight. Eating a burger patty from McDonald's and fresh organic ground beef of the same weight and fat content ISN'T distinguished by the body. All it does is break it down to it's simplest form for absorption (amino acids). Now WHOLE FOODS do hold more nutritional value and many times are less calorie dense, but don't let that whole "clean" eating fool you into thinking that's your cause for weight loss. It still boils down to calorie deficit. Not mention, like any other "diet", unless you're WILLING to eat that way for life, you're likely to regain when you get to indulge in the foods that aren't "clean" again. It's a typical cycle I've seen over and over again in the decades I've done this.

    I'm a bodybuilder for life and can tell you emphatically that I ate whatever I wanted (pizza and burgers) to bulk up and when I prepped for contests, I just ate more whole foods and less all the way up till contest finished. Then gorged again because I HATED the process of getting cut for contests. It's a lot of work for no payoff and possibly no placing.
    So how have I stayed in shape for 35+ years? I controlled my overall CALORIES. Yesterday I had M&Ms, tortilla chips and ice cream. So called "junk foods". And ENJOYED every minute of it. I just don't eat 5 servings of each. As mentioned the whole "clean eating" is a fitness myth that's been endorsed by trainers who really aren't in the know. They are just parroting what they hear without actually understanding how the body actually works. It doesn't HURT to eat "clean" (again subjective terminology because a vegan would think eating meat is "dirty") but if it's NOT a way you intend to stick to for life, weight regain is highly likely. You're much better off learning habitual behavior of learning how to control consumption of foods you actually like and enjoy.

    Dude all that means is you're eating in a calorie deficit. It's working now because of that. But let me ask you: are you ENJOYING eating that way? If so, then kudos to you. Because I can tell you now that if you hang out with friends or family THAT DON'T eat that way, you'll be in a mental fight if you're wanting to be able to indulge but can't because you got in your head that "processed" foods are voodoo. But I digress. You're not my client and I'm not here to sabotage your trainer. I'm just giving you advice from what I've done as a trainer for 35+ years with others successfully.

    Good news on the weight loss.
    But seriously often personal trainers are the worst source of bro-science imaginable. Unless they have taken additional training in nutrition they really should stick to helping people with their exercise - that's what their PT qualification is actually all about.

    I congratulate you on your aim to eat better but I really do fear that your are being dragged into pointless worm holes of fasted cardio and clean eating.

    But that still isn't a nutrition qualification. You seem to be missing the point - you're down 2kg because you ate less per day than you burned. Not because you ate clean.

    Even if you're not counting calories, ALL fat loss is down to a calorie deficit.

    Oveas I know that I'm in a calorie deficit
