How much can exercise combat the effects of junk food?

    Just wondering what people think, to what extent can exercise mitigate the negative effects of junk food? I eat reasonably healthy breakfast, lunch and dinner, but I go through phases of bingeing on sugar and junk food. I'll still eat decent regular meals, but they'll be interspersed with bars, chocolate, biscuits and even bowls of cereal loaded with sugar if I can't find anything else. I exercise regularly, running and cycling. I'm not trying to lose weight, more concerned with the impact of junk food on my body, especially sugar as it seems the hardest to kick and more and more research seems to be showing its harmful long term effects, particularly on the mind

    To the extent that the calories ingested are expended during exercise is the simple answer but I think you'll eat junk food at a much greater rate than you can burn it off so it's always an uphill struggle in terms of weight management.

    In my experience junk food makes me tired and sluggish, and sugar is an addiction, the more you eat the more you want.

    In simple terms it is a question of using the calories you eat, but for me anyway I feel better when I eat clean. Exercise doesn't negate the effect that eating junk has on me at all, though it does stop me turning into a blimp.

    You are what you eat. Exercise doesn't make the fact you put junk into your body go away.

    Watch HUNGRY FOR CHANGE its a really good documentary.

    It's not just a simple case of burn more calories than you eat, nutrition isn't that black and white.

    A lot of fast food is extremely high in simple carbs and saturated fats and heavy in salt. So, it's a case of what will these things actually do to your body, rather than how quickly you can burn off the calories. Simple carbs may be good in some cases, but if you're eating a massive quantity of them it'll spike your insulin levels, too much and your body will store this as energy in forms, and in fat. Saturated fats and salt will effect your cholesterol levels.

    That's just a brief overview on some of the things wrong with junk food, the list is endless. You're also not getting your minumum requirements of vitamins and nutritions to keep your healthy, fit and sane.

    Thats what I'm asking though, how much can exercise counteract the negative effects? I'd imagine someone who eats pizza and burgers everyday but also runs 50 miles a week would be in a better state of health than if they kept the same diet but did no exercise.

    They'll still be ingesting the same crap so I don't know how you think the person who doesn't exercise would be in a better state of health than someone who does.

    That's the complete opposite of what I've said

    So it is. I completely misread it.

    Exercise won't help things like how your organs react to stuff you put into your body.

    It's like saying I drink 5 pints of beer every day and a smoke, I also do a load of recreational drugs every weekend. But it's okay, cuz I do 5k everyday.

    Okay, so that's a bit hyperbolic, but you get my point. If you're building up cholesterol and other stuff in your organs/heart/etc exercise won't fix that.

    Having said that, I'm a believe in treats. You should eat clean for 95% of your diet, but you need to be allowed treats, for sanity and health purposes. Also, if you limit yourself to 5% or something like that you'll ensure your treats are good! i.e; a cheat meal every 2nd sunday, if you only get it every 2nd sunday you won't go down to supermacs and buy a couple of taco chip portions, but might be more inclined to eat a good quality cooked meal that may be considered a cheat, like a good italian meal or chinese etc.

    The point is everything is tolerable, within it's limits. Too much of anything can kill you, like your mother might say. So that odd bit of junk food is fine, so long as it's not habitual and often.

    I've been on a very strict nutrition plan for the last 6 weeks. After getting over the first couple of weeks my cravings completely subside. In the first week I wanted fish n chips, and I wouldn't usually be that keen on it, but I had the cravings for greasy food....

    Now I'm like I'll treat myself to brunch on Sundays or something like that. Good for the soul, and I don't get cravings for junk food anymore.

    Id rather be a healthy eating non-exerciser than a junk food exerciser. Look at the pot bellies on AstroTurf pitches, I've mates that play soccer 4 times a week and are still puddings

    Also to answer your question, I would say somebody who doesn't exercise but eats right will be completely more healthier than someone who exercises but doesn't eat properly. Why? Because you don't need to exercise to be healthy. Just walking, talking, working, commuting is often enough for a lot of people, so long as they're not eating a surplus of calories.

    Will they be fitter? No, but that's another question.

    Effects of junk food:
    Excess calories - work out
    Excess salt - drink more water :(
    Excess cholesterol - take more statins :eek:
    Missing nutrients - have healthy meal after your burger :eek:*2

    Exercise cant do anything about most of the problems junk food causes


  • Registered Users Posts: 39,057 ✭✭✭✭Mellor


    Considering how exercise can offset junk is really a pointless conversation. It can't, the two are separate issues.
    If somebody has a high nutritional and calorific requirement due to intensity of their training, then maybe they get away with some junk to meet their goals. But if you have to ask the question, it doesn't apply to you. You should be even thinking about it unless you know nutrition inside and out.
    Just because you go to the gym a couple times a week doesn't mean you have a high requirement. Most people are just showing up and going through the motions. Most people who think they meet that intensity, are kidding themselves imo

    Hey, I earn my 19 pints, two Burger Kings, one fry up and one Dominoes meal deal for 4 over the weekend thank you very much. I also earn the right to have a total of ~15 hours ****ty sleep between Friday and Monday incase you were wondering.

    Eat Big, Drink Big, Train Big (lol, maybe!) imo.

    Sometimes eating sugary foods is a necessity during intensive training. I had to do it during marathon training in order to compensate for calories lost. By all means, if you have the time to eat healthier while training as an athlete, do just that, but if you don't, a packet of biscuits is just as good.


  • Registered Users Posts: 1,326 ✭✭✭MartyMcFly84


    I would say for longevity it would be better to do little or low intensity exercise but eat a good nutrient rich diet and sticking within your body maintenance levels.

    As mentioned there is a lot of harmful stuff in junk food (hence the name), not just the calorie content. The excessive sugar will mess with your insulin levels and can lead to diabetes to name but one disease caused by poor nutrition.

    I get the impression you are asking this question as you kind of want to rationalise what you already know, you have bad eating habits and are hoping people will say "as long as you exercise you will be grand". Eating habits are often life long and can be difficult to break. Do you think you will be able to maintain your current exercise levels 20 or 30 years from now? will you still be eating the same?

    Long story short, the sooner you break your current binging habits and sugar addiction the healthier you will be in the long run. Aim to eat well 90-95%% of the time. Processed sugar is empty calories that your body simply does not need, much the same with tobacco. Its something that can be difficult to quit but it can be done with will power and if you really want to do it.

    If you are an olympic athlete you can get away with it apparently, but these guys need to eat like 10000 calories a day and spend most of their waking time training.

    I wouldn't say I'm trying to rationalise it, I'm aware that I feel worse if I eat poorly, especially when it comes to running and for optimal health you'd need a good diet in conjunction with exercise. I'm just curious as to what extent it can mitigate against some of the negative effects.

    To my mind, it would have to mitigate it to some extent. Look at any of the benefits of exercise, it'll give stuff like improved heart health, improving insulin response, lessens depression etc. Even taking weight, exercise can counter weight gain. If you had a person and you were to look at them in a year, they'd presumably be healthier if they exercised regularly in that year than if they remained sedentary?

    Great for 1% of the population with the genes and even less than 1% with the skill and mental focus to make it to the Olympics.

    I am sure they would only eat like that for a very short period of their life, you better believe as soon as they cease to train at that level their diets change drastically, or they would become obese pretty quickly.

    Ok so if two identical twins had the same poor diet. But one exercised a few times a week who would be healthier? Probably the one who did some exercise, but he would not be healthy.

    Same if one smoked 20 fags a day and the other smoked 10. Or they both smoked 10 a day but one ran 5k twice a week.

    As others have said, it is the effect the Fast food will have on your system, given the nature of it.. 'engineered' to keep you hungry, you're onto a loser.

    If you separated the salt/sugar from many processed foods and presented it to someone to lick off of a table surface, with the threat of a dig, there'd be punches flying soon after.

    Took weeks for me to lose my salt and sugar craving, now that I barely have salt in my diet, when I do decide to have something fancy, say, bread/quiche from somewhere like Avoca, I find it almost inedible, due to the salt content.

    It's only with a break and the gift of hindsight that many folk will realise how messed up their body chemistry is..

    Excercise can offset some sins, but if you're doing 30 minutes a day to offset a family sized pizza devoured late in the evening, well.. good luck with that.

    That's largely a myth.

    How do you explain Michael Phelps' diet then? Stuffs his face with icecream and pizza while training.

    Like I said, it's a myth. It was a story that appeared in one paper, then got regurgitated around the world.
    “I never ate that much. It’s all a myth. I’ve never eaten that many calories. I wish! It’s just too much though. It would be impossible.”


  • Registered Users Posts: 7,157 ✭✭✭srsly78


    He didn't deny eating pizza and icecream tho? Maybe the 10000 calories was an exxageration, what did he actually eat?

    edit: I found the interview where he denies eating that much. He says that 12000 was an exxageration, he actually ate 8000-10000 :D


  • Closed Accounts Posts: 177 ✭✭Last_Minute


    Eat well the vast majority of the time and get some exercise in during the week, then you can afford to eat whatever you want for 2-3 meals a week be it fish and chips, pizza and not have to worry about weight gain in the slightest.

    Yes, junk food does your body no favors but it's just so nice!

    Pizza and pasta probably. He'd need carbs. Ice cream, I doubt it.

    This is it.

    Once the majority of your diet is good then having the odd treat is going to do no harm, assuming of course it really is "the odd time" ;)

    On a slightly serious note, it IS possible to make progress with a bad diet imo. Depending on what you define as progress. If you hammer away at a decent program with intensity five days a week then you can gain strength and work capacity despite a bad diet and poor sleep, etc. That's definitely my experience.

    Will it be all the progress you can make? Well I'm sure it won't be, and you ain't going to end up sub 15% body fat.

    I think talking in extremes is always incorrect however, that's the bottom line. Saying 'you can't make progress with a bad diet' is as silly as saying 'Olympians can eat 10k calories of junk and be ripped specimens of human performance'.
