New guidelines issued from the American College of Sports Medicine (ACSM) state that 30 minutes of exercise, 5 days a week might not be enough. In 2001, ACSM recommended that overweight and obese adults get at least 150 minutes of moderate-intensity exercise per week to improve their health. 200 to 300 minutes per week was recommended for long-term weight loss. But will this amount of exercise really help you lose weight and keep it off?

New research shows that "between 150 and 250 minutes per week of moderate intensity physical activity is effective in preventing weight gain greater than 3% in most adults but will provide "only modest" weight loss." So ACSM has published new physical activity recommendations in the journal Medicine & Science in Sports & Exercise. Overweight and obese individuals are more likely to lose weight and keep it off if they exercise for least 250 minutes per week. Exercising for more than 250 minutes per week has resulted in "significant" weight loss for these individuals.

So what does this mean? If you're trying to lose weight, 50 minutes of cardio exercise along with regular strength training might be what it takes to see the results you're hoping for.


What do you think? Does 50 minutes of exercise, 5 days a week seem like a lot to you? Or is that in line with what you're already doing? What amount of daily exercise has given you the best results?

    After skimming some of the comments, it seems like exercise is greatly a personal preference.
    Its been told again and again that if you exercise for hours, if you go home and eat junk that exceed the amount of calories burned, you'll gain weight. Even eating a low calorie amount of junk, exercise won't give you all the results of healthy eating and calorie control.

    I think its all about how you personally approach it.

    People have lost weight just eating right, some incorporating both.

    50 minutes a day does sound like a lot. Maybe as time goes on and you've met a goal of 30 minutes a day getting up to 50. I know for me, I'm not ready to make my goal so large.

    Weight loss is 80% or more diet, so this information is misleading. Weight loss can be achieved by diet alone, so any exercise you get is GREAT. Eat Healthy and in moderation and move around a bit and you're well on your way. - 7/24/2014   3:49:46 AM

    Zero. Sorry, I've lost more weight NOT exercising than exercising. The body is much, much more complex than simple calories in -vs- calories out.

    If you're stressing out about exercising enough, that alone will cause you to gain weight due to shifts in stress hormones.

    If you exercise more, you need to eat more, or you'll still send your body into starvation mode.

    There are LOTS of reasons to exercise - it helps you to feel better, gain mobility, flexibility, cardiac health, circulation, stamina, etc. But you don't need to exercise to lose weight. - 7/23/2014   7:22:57 PM

    I unhitched exercise from weight loss. I exercise daily to increase my mood & energy. It's a great stress reliever. Exercise is also great for bone & heart health. So definitely people should exercise. Any calories burned are a bonus.

    Nutrition is more important for weight loss. Have a small caloric deficit most days. I like to focus on portions control, especially not having second helpings at dinner. I also only have dessert once a week. Besides saving 500 calories a day, it's more of a treat when I have dessert on a Saturday night. If I really need a sweet after dinner, a nice piece of fruit or a yogurt will do. - 7/23/2014   3:36:03 PM

    You have to burn 3000 calories to lose 1 pound!! Being post menopausal, it doesn't matter if I work out for an hour and watch my intake, I cannot lose weight because of hormone imbalance and estrogen dominance. It took me swimming 20 laps 6 days a WK for a month to lose 5 lbs!! No more. I believe resistance
    training with free weights with intense short bursts 15-20
    workouts (MRT) keeps you burning calories up to 48 hours post.
    Cardio only shows to burn calories for the period of time you
    workout while Metabolic resistance Training gets you the same
    result with half the time. Check out Shaun Hadsall's video's &
    workouts on Tube or MRT's on U Tube. He also teaches about the science of food, that if you want to loss weight after a intense workout, delay eating for at least 45-60 minutes so fat stores will be depleted. - 7/23/2014   9:37:51 AM

    You can exercise for 4 hours a day but if you are eating too many calories you won't lose weight. If you watch what you eat 50 minutes a day 5 days a week may be enough. For me it's all about calories consumed. - 7/23/2014   9:13:27 AM

    I read the article quickly, but looked to me like they were isolating exercise as a method for weight loss ( a good study will eliminate other variables) so they didn't take into account control of calories. Perhaps less exercise combined with some calorie restriction would be fine. I also image that it will depend on the individual how much exercise is necessary. I am so far finding that reasonable calorie control (not starving) and moderate exercise (brisk walking) 4 times per week helps me lose weight. We will see if I hit a plateau and what I need then. Whether you lose weight or not the exercise will only benefit you, so do whatever you can. Find something you like and go for it. - 7/23/2014   8:27:58 AM

    Exercise is critical to the health benefits of weight loss, in my opinion. In addition to providing those endorphins, exercise strengthens your heart and lungs, convinced your body to make your bones more dense and hang on to the bone density you already have, helps you sleep better (and good sleep had also been shown to be important to weight loss), and gives you another thing by which to measure progress besides the scale. This last factor is incredibly important if you're in this for the long haul, for a permanent change.

    My biochemist husband is fond of saying this: "If there was a pill that would cause you to lose weight, reduce your risk of all diseases, live longer and have a better health expectancy (length of life spent healthy, not just alive), would you take that pill? We have that pill. It's exercise."

    You have to sweat, and you have to do it for at least an hour, averaging 5-6 days a week. That doesn't necessarily mean M-S you work out for an hour per day. It might be 3 days during the week, and then a 3 hour hike on Sunday, or a thirty-minute bike commute one-way every weekday, supplemented by time on and indoor climbing wall when the weather's crappy. The key is finding things you love enough to keep doing. I do races, so my workouts aren't just workouts, they'd time I'm committing to support myself as an athlete. An athlete doesn't sleep in just because it's raining on a run day, she gets up and puts the miles in. She doesn't put food in her body mindlessly, she thinks about what will fuel her body, mind, and soul, and then makes a choice appropriate to that meal. - 7/23/2014   1:00:42 AM

    Right now im doing 45 minutes a day 7 days a week. And after two months of losing 15 pounds im now maintaining. So for me right now thats not enough for weight loss. - 7/23/2014   12:25:16 AM

    In my opinion, if you are shooting for 50 minutes a day every day, then you are setting yourself up to fail. You need to do what works best for you. I exercised 7 days a week for 40 minutes at a time and I still lost weight and have kept it off for 4 years! I don't go by recommendation, but how I feel and how my clothes fit. If you have the time to step it up on particular days, then I say go for it, but otherwise, don't injure yourself trying to be hero!
    - 7/22/2014   11:59:47 PM
  • 1135
    That does NOT seem like a lot. I need a minimum of 350 a week just for maintenance. If I want to lose I need to aim for something closer to 550. I notice that most of my Spark friends who have lost significant amounts of weight and kept it off tend to exercise this much. I think that Spark is VERY far off base in its exercise recommendations. - 7/22/2014   11:00:21 PM

    Im on the fence. I work out 45-60 minutes doing a combo of cardio and strength. My strength training is done at a high intensity after my cardio. That way my heart rate is already elevated and it stays elevated throughout the workout. I eat 4 or 5 small meals a day. In 6 weeks I've lost about 12 pounds. I struggle with polycystic ovaries, so i don't shed the weight as quickly as others. Each person has to find what works for him or her. I see muscle definition and looser clothes, so i'm happy. I'd love to lose faster, but i have to balance 2 young kids, a full time job, and anything else the army life throws at me. - 7/22/2014   9:52:06 PM
  • 1133
    I completely agree. Especially when you hit plateaus. I lost 55 pounds 4 years ago. At first I was able to lose weight with 30 minutes a day, but I'd plateau and have to up my minutes. Believe me, if you want it bad enough, you'll find the time. I did with a full time job and two young kids. You prioritize it. - 7/22/2014   9:45:13 PM

    50 minutes 5 days a week!!! when am I supposed to find time for that? And get 8 hrs of sleep a night? and work 9 hours a day?

    250 minutes a week is a great goal, but most people who need to lose weight will have to work up to this. If you haven't exercised in months or years, it's better to start small (10-15 minutes) and add a few minutes every week. Intensity is also a factor! You might only need 30 minutes if you really go for it.

    I also agree with the person that said exercising more than 45 minutes will increase the risk of injury. For me, a good 30-45 minute walk 4 times a week plus strength training 2-3 times a week is my ideal exercise week.

    But I also think that it's 2/3 about what you eat! And the other 1/3 of exercise is to help with that and release positive chemicals in your body and get your metabolism going. - 7/22/2014   9:16:40 PM

    It greatly depends on the person. Back when I lost 55 pounds, in 6 months, it was doing 30 minutes of light cardio, 6 days a week. I was doing primarily Leslie Sansone videos. Saying everyone needs 300+ minutes a week to lose weight... that's ludicrous, especially for those of us who suffer chronic pain.

    When I last was working out like a demon to lose weight, it was 1 to 2hrs of high intensity work outs per day, 6 days per week. Ultimately, I knew that it was not sustainable for me. Right now, I am just looking to exercise moderately (30 +) minutes per day. My motivation is different now. I am exercising for HEALTH reasons, not weight loss. Working out for weight-loss was a doomed proposition for me. If you can do it for the rest of your life, great, but I could not sustain the effort needed. When I was working out intensively, I lost relatively little weight due to exercise, most of it came off with dieting. And as with 95% of diets, I ultimately failed and regained all the weight. I just want to be healthy now. The number on the scale is no longer my prime motivator. - 7/16/2014   9:36:31 PM

    Right Now I exercise approximately 400 minutes a week (6 days). I do anywhere between 30 to 45 minutes of cardio a day (walking on the treadmill) and then strength and I lost 11lbs since starting that programme. I feel strong when I'm done, though I do get the slight muscle fatigue that's expected, PLUS with tracking my meals to take into account the calories I've burned, I am able to eat what I like and still see the benefits. Right now I think I am the healthiest I have been in years if not ever. - 7/16/2014   2:08:49 PM

    I'm only doing about 120 a week and losing fine. Then again I'm not exactly inactive outside of that. I don't drive and live in a city so I have more walking than many already figured in to day to day life. I also do all my own housework PLUS some of my in-laws (they have a farm and I don't have the desire to do outside chores at all so while they and hubby do that, I take care of the house and my nephew). - 7/16/2014   1:48:44 PM

    Great insights. I was losing weight consistently, WITHOUT exercise, and lost lots of weight over a year. Staying on the same diet, i started training for a marathon by walking 20+ miles a week, and the weight loss slowed, practically to a standstill, for the past 5 months, without the benefit of increased FAT loss. So, go figure! Do what works. - 7/16/2014   12:19:01 PM

    I find this to be true. I was doing 200 a week but I found it wasn't quite enough. 250 leads to loss for me. I'm not a gym rat or anything. I find that an hour once or twice a week, plus ten minutes here and there throughout the day is enough. It is hard to do every week but when I do it I see results.

    Don't forget that exercise also comes in the form of dancing with your friends on weekends and cleaning the house and gardening in the yard. It's not just the traditional cardio and weights so you can have time for it.

    This morning I did a 25 minute yoga video and walked from my car to work (14 min. there and back) so I'm at 39 mins. already at 8:00 a.m. I'll take a 12 minute walk on my work break and I'm almost there. Yesterday I did an exercise video and 4 small walks. - 7/16/2014   12:08:59 PM

    I exercise AT LEAST 180 minutes per week; as a matter-of-fact, since starting here April 1st, there was only 1 week that I did less than that (97 minutes that week). I usually do over 200 minutes per week (I don't think I've reached 250 in 1 week yet, though), and I track all of my food. 250 minutes per week seems like a lot to me, especially with my work schedule. I do the best that I can and hope for the best. - 7/16/2014   12:06:05 PM

    My doctor told me that, for me, (back when I was 45) I'd need to exercise 60 min a day 5-6 days a week to lose any weight at all. And I have a restricted diet already due to pre-diabetes and gout. I didn't believe her but I found walking 3 miles of hills 4 days a week didn't make me lose weight at all. I got healthier but didn't lose. - 7/16/2014   8:51:05 AM

    You don't have to exercise at all. You can still lose weight-if you want to eat very little, be hungry, and be unhealthy. Exercise will lower your bp, lower your cholesterol, lower your blood sugar, improve your stamina, both mentally and physically, lower your depression, and help you sleep. ETC. The body needs exercise. 20 minutes a day is good. 60 is even better! You do what you can; but there is no magic pill, or diet that will ever take its place.

    I don't have time to brush my teeth, take a shower, or drive to work. I do all of them because I have to. Same with exercise. I would rather sit around watching tv, or playing on the computer. But, for my health, I must do more. - 6/7/2014   7:49:17 PM

    From my personal experience, my weight is impacted MUCH more by what I eat than by how much I exercise. It doesn't sound like this study took diet into consideration at all. In February, I followed Haylie Pomroy's Fast Metabolism Diet pretty strictly (confuse to lose, no wheat, whole grains only, no dairy, no sugar, no corn, eating with 3 cycles a week, 3 meals and 2 snacks every day). I was able to keep it up for about 3 weeks to the letter and have done my best since then. I lost 14 lbs the first month and am down another 8 lbs since then. I follow the general guidelines for the most part, but don't eat in cycles. I don't weigh over holidays or when I'm on my cycle, and enjoy birthday parties to the fullest. If I'm craving something, I eat it. Then I get right back on track. Most importantly, I'm nice to myself and don't feel guilty when I have a less-than-stellar day. I have an active job and am on my feet all day and haven't added any exercise above and beyond what I do at work. My body has just gotten more efficient. Two years ago, I exercised all week and followed the SP diet and didn't lose hardly anything. I now use SP to track my weight and to keep my health at the forefront of my mind. Every body and every mind is different, so you have to find what works for you and stick with it! - 5/26/2014   9:09:31 AM

    I thought it was just me but I noticed that I need the 250 minutes to lose. I've been experimenting with higher intensity, shorter workouts it the scale won't budge so I'm going back to 250 minutes per week. - 5/15/2014   12:11:17 PM

    I'm thrilled to see this, as the men in my life (husband, dad, friends) have been warning me against too much cardio. (And I will be honest - I LOVE cardio!) I'm doing strength training as well (alternating days), but only getting about 30 minutes of cardio each day (5 days/week). I'm just not seeing the results that I want to see at this point. I'm going to up my cardio time and see if it helps. Have I mentioned that I am thrilled by this? :) - 4/11/2014   3:58:27 PM

    I go to the gym 6 days a week, I work out for 35 minutes at usually high intensity on the recumbent with the hills and alpine programs, Saturdays is my long day as I have the day off from work and that is an hour. I am dropping a lot of weight quite quickly, and am watching what i eat with a lot of protein, healthy fruits and veggies and complex carbs. I drink a lot of water everyday and treat myself on Sunday with something that I would not normally eat, such as a slice of pizza, etc,,,,this keeps any cravings away for me. I feel great as long as I go to the gym in the morning. - 4/10/2014   11:31:46 PM

    New guidelines means, yet again, the old information was wrong. I choose not to worry about the latest soon-to-be-wrong information.

    The important thing for each person is to figure out what works for them. I've learned that a lot of guidance out there does not lead to weight loss for me (e.g., calories in/out). That's not to say it won't work for others. - 2/1/2014   3:31:06 PM

    I think that's why it's important to learn to just be consistent. That's what I'm doing this year. Start at 10 minutes and work to 60 minutes. If I shoot for that 50 minutes right now, I will fail because I'm a single Mom working full-time and losing my job in a few months so now I have to add job hunting to the list. It's made doing 10 minutes of exercise a day a challenge, but it's a more doable goal so I just shoot for that. Once I can consistently do that, I will up it to 15 minutes. If I do more, great. I just make my goal to be consistent. - 2/1/2014   7:57:52 AM

    The only way I can spend that much time exercising per week is if I did not have to work full-time to make a living and sometimes take work home with me. It is completely unrealistic for busy people like myself to have that much time to devote to exercise. It's often difficult to even do 30 min. 5 days a week with it sometimes being only 4 days a week. It's also difficult to eat the small quantities that achieves weight loss and not still be hungry and frustrated. These are the challenges I face in trying to lose weight and don't really know of any easy answers other than to pray I get a windfall of money and can retire! - 1/31/2014   12:13:48 PM

    I guess after reading all the comments I fall into the doesn't seem excessive category. I work out for 50 minutes 6 days a week. Two days with a trainer on strength and four days of cardio. I also watch what I eat and drink and get plenty of sleep. I have lost 20 pounds in 3 months and am within 10 pounds of goal weight. I work 40+ hours a week and find that if I go to the gym before work and get it done my mood is better and I never have to worry about me talking myself out of a workout. So at 6:00am most days you'll see me at the gym :-) - 1/31/2014   12:03:20 PM

    Several weeks ago it wouldn't have made sense. For the last 2 weeks I have been getting up at 5:00 a.m. and doing 60-80 minutes on the treadmill x7. I am watching my calories too. I realized that if I do this first thing, I don't get distracted and not get my cardio done. I have found that everything about my day is better since I've been doing this. If for some unusual reason I don't get my treadmill done first thing, its much easier to find time in the evening. - 1/31/2014   11:39:52 AM

    In the past I've been a regular exerciser...20-30 min. of moderate cardio (walking on the treadmill) and about 15 min. of strength training. It took me 1 year to reach my weight goal, just by cutting back on my regular diet (Mediterranean) and I have kept that and more off for more than 2 years now, basically without any regular exercise because of joint and muscle problems that kept me from my routine. That fact combined with the number of people I saw at the gym that were warrior exercisers with excess weight, I'm convinced that it is what and how much you eat. I still aim to incorporate moderate exercise, especially core training I learned from a personal trainer for the obvious health benefits. But I gave up the gym membership and do what I can, so far successfully. - 1/31/2014   11:14:23 AM

    Sounds about like what I'm doing. An hour a day, 5 days a week. More on weekends, try to stay active all day with an hour cardio session thrown in. I invested in a good elliptical for my home so that helps a lot, and it's fun to go to the gym on the weekends and stay for a couple of hours instead of being rushed. I've always needed to do this though, I used to get so irritated at those who could walk 30 minutes a day and stay fit! I have to get my heart rate up to 150-175 for a solid hour at least 5 times a week to see any weight loss at all. - 1/31/2014   12:34:39 AM

    The thing that got me was not just 50 minutes, but: "50 minutes of cardio exercise along with regular strength training". Wow that's some amount of time.

    I count calories very carefully, but need to do one hour of exercise every day to lose weight. I walk for 30 minutes in the morning and do 30 min. on the elliptical at night. I also lift weights three times a week. Now that I'm over 40, it's the only way for me to lose. I've tried eating less, but then my blood sugar plummets and I can't do anything.
    Studies show that inactivity is really bad for you, so I intend to stay as active as possible. - 1/30/2014   3:48:55 PM

    My clients would immediately give up if I told them they need to do an hour of exercise a day!! Interval training - high intensity (for them) works! Even in five minutes blocks - I have templates of 10 minutes program following 4,3,2,1 method and goal is to do 3 sets a day. But then I use hypnosis to change their mind about food first. 50 minutes a day of exercise is nonsense - don't think I do that most days! - 1/30/2014   3:22:09 PM
