1 00:00:00,030 --> 00:00:02,780 we've got some bad news you could be 2 00:00:02,780 --> 00:00:02,790 we've got some bad news you could be 3 00:00:02,790 --> 00:00:05,240 we've got some bad news you could be burning fewer calories at the gym than 4 00:00:05,240 --> 00:00:05,250 burning fewer calories at the gym than 5 00:00:05,250 --> 00:00:07,900 burning fewer calories at the gym than you think in a study published in 2018 6 00:00:07,900 --> 00:00:07,910 you think in a study published in 2018 7 00:00:07,910 --> 00:00:10,070 you think in a study published in 2018 researchers found that some ellipticals 8 00:00:10,070 --> 00:00:10,080 researchers found that some ellipticals 9 00:00:10,080 --> 00:00:12,379 researchers found that some ellipticals overestimate calories burned by as much 10 00:00:12,379 --> 00:00:12,389 overestimate calories burned by as much 11 00:00:12,389 --> 00:00:15,049 overestimate calories burned by as much as 130 calories per 30 minutes of 12 00:00:15,049 --> 00:00:15,059 as 130 calories per 30 minutes of 13 00:00:15,059 --> 00:00:17,029 as 130 calories per 30 minutes of exercise now to put that in perspective 14 00:00:17,029 --> 00:00:17,039 exercise now to put that in perspective 15 00:00:17,039 --> 00:00:20,240 exercise now to put that in perspective if you ate an extra 130 calories of food 16 00:00:20,240 --> 00:00:20,250 if you ate an extra 130 calories of food 17 00:00:20,250 --> 00:00:22,070 if you ate an extra 130 calories of food each day you'd put on more than a pound 18 00:00:22,070 --> 00:00:22,080 each day you'd put on more than a pound 19 00:00:22,080 --> 00:00:26,210 each day you'd put on more than a pound each month or 13.5 pounds a year and as 20 00:00:26,210 --> 00:00:26,220 each month or 13.5 pounds a year and as 21 00:00:26,220 --> 00:00:29,120 each month or 13.5 pounds a year and as it turns out ellipticals aren't the only 22 00:00:29,120 --> 00:00:29,130 it turns out ellipticals aren't the only 23 00:00:29,130 --> 00:00:34,990 it turns out ellipticals aren't the only machines with imprecise calorie counters 24 00:00:34,990 --> 00:00:35,000 25 00:00:35,000 --> 00:00:37,280 well when you talk about the the 26 00:00:37,280 --> 00:00:37,290 well when you talk about the the 27 00:00:37,290 --> 00:00:39,340 well when you talk about the the calculations here they are way off 28 00:00:39,340 --> 00:00:39,350 calculations here they are way off 29 00:00:39,350 --> 00:00:43,190 calculations here they are way off so they are so much off you can't really 30 00:00:43,190 --> 00:00:43,200 so they are so much off you can't really 31 00:00:43,200 --> 00:00:45,459 so they are so much off you can't really use the information meaning that it's 32 00:00:45,459 --> 00:00:45,469 use the information meaning that it's 33 00:00:45,469 --> 00:00:48,950 use the information meaning that it's can be more than 50% off now for some 34 00:00:48,950 --> 00:00:48,960 can be more than 50% off now for some 35 00:00:48,960 --> 00:00:51,830 can be more than 50% off now for some counting calories isn't the point during 36 00:00:51,830 --> 00:00:51,840 counting calories isn't the point during 37 00:00:51,840 --> 00:00:53,389 counting calories isn't the point during it for the other benefits exercise 38 00:00:53,389 --> 00:00:53,399 it for the other benefits exercise 39 00:00:53,399 --> 00:00:56,060 it for the other benefits exercise offers but for the nearly 50% of 40 00:00:56,060 --> 00:00:56,070 offers but for the nearly 50% of 41 00:00:56,070 --> 00:00:58,459 offers but for the nearly 50% of Americans who have at some point tried 42 00:00:58,459 --> 00:00:58,469 Americans who have at some point tried 43 00:00:58,469 --> 00:01:01,160 Americans who have at some point tried to lose weight it really does matter and 44 00:01:01,160 --> 00:01:01,170 to lose weight it really does matter and 45 00:01:01,170 --> 00:01:03,229 to lose weight it really does matter and that's because people might eat more 46 00:01:03,229 --> 00:01:03,239 that's because people might eat more 47 00:01:03,239 --> 00:01:04,490 that's because people might eat more when they think they're burning more 48 00:01:04,490 --> 00:01:04,500 when they think they're burning more 49 00:01:04,500 --> 00:01:07,399 when they think they're burning more calories the participants in the the 50 00:01:07,399 --> 00:01:07,409 calories the participants in the the 51 00:01:07,409 --> 00:01:10,190 calories the participants in the the group that had fitness trackers Fitbit 52 00:01:10,190 --> 00:01:10,200 group that had fitness trackers Fitbit 53 00:01:10,200 --> 00:01:12,859 group that had fitness trackers Fitbit monitors they actually didn't lose as 54 00:01:12,859 --> 00:01:12,869 monitors they actually didn't lose as 55 00:01:12,869 --> 00:01:14,480 monitors they actually didn't lose as much weight as the people that didn't 56 00:01:14,480 --> 00:01:14,490 much weight as the people that didn't 57 00:01:14,490 --> 00:01:16,640 much weight as the people that didn't have anything and one reason to thought 58 00:01:16,640 --> 00:01:16,650 have anything and one reason to thought 59 00:01:16,650 --> 00:01:19,429 have anything and one reason to thought might be that they were overestimated in 60 00:01:19,429 --> 00:01:19,439 might be that they were overestimated in 61 00:01:19,439 --> 00:01:21,140 might be that they were overestimated in terms of energy expenditure so they 62 00:01:21,140 --> 00:01:21,150 terms of energy expenditure so they 63 00:01:21,150 --> 00:01:23,179 terms of energy expenditure so they allowed themselves to eat more and their 64 00:01:23,179 --> 00:01:23,189 allowed themselves to eat more and their 65 00:01:23,189 --> 00:01:24,920 allowed themselves to eat more and their food didn't lose the lose as much weight 66 00:01:24,920 --> 00:01:24,930 food didn't lose the lose as much weight 67 00:01:24,930 --> 00:01:27,499 food didn't lose the lose as much weight now the formula for losing weight may 68 00:01:27,499 --> 00:01:27,509 now the formula for losing weight may 69 00:01:27,509 --> 00:01:29,810 now the formula for losing weight may look simple burn more calories than you 70 00:01:29,810 --> 00:01:29,820 look simple burn more calories than you 71 00:01:29,820 --> 00:01:32,149 look simple burn more calories than you consume but actually measuring calories 72 00:01:32,149 --> 00:01:32,159 consume but actually measuring calories 73 00:01:32,159 --> 00:01:35,330 consume but actually measuring calories isn't at least on your typical exercise 74 00:01:35,330 --> 00:01:35,340 isn't at least on your typical exercise 75 00:01:35,340 --> 00:01:37,789 isn't at least on your typical exercise machine a reason it's so difficult to 76 00:01:37,789 --> 00:01:37,799 machine a reason it's so difficult to 77 00:01:37,799 --> 00:01:40,130 machine a reason it's so difficult to get the calorie count correct is that 78 00:01:40,130 --> 00:01:40,140 get the calorie count correct is that 79 00:01:40,140 --> 00:01:42,140 get the calorie count correct is that you're not really measuring the calorie 80 00:01:42,140 --> 00:01:42,150 you're not really measuring the calorie 81 00:01:42,150 --> 00:01:44,450 you're not really measuring the calorie counts so to do that you need to to 82 00:01:44,450 --> 00:01:44,460 counts so to do that you need to to 83 00:01:44,460 --> 00:01:45,980 counts so to do that you need to to measure all the cells in your body and 84 00:01:45,980 --> 00:01:45,990 measure all the cells in your body and 85 00:01:45,990 --> 00:01:48,020 measure all the cells in your body and how much energy they are using but 86 00:01:48,020 --> 00:01:48,030 how much energy they are using but 87 00:01:48,030 --> 00:01:49,670 how much energy they are using but obviously you're not going to do that so 88 00:01:49,670 --> 00:01:49,680 obviously you're not going to do that so 89 00:01:49,680 --> 00:01:52,460 obviously you're not going to do that so instead you try to do some other proxies 90 00:01:52,460 --> 00:01:52,470 instead you try to do some other proxies 91 00:01:52,470 --> 00:01:54,109 instead you try to do some other proxies for that so you might measure the 92 00:01:54,109 --> 00:01:54,119 for that so you might measure the 93 00:01:54,119 --> 00:01:55,910 for that so you might measure the distance you're traveling or you might 94 00:01:55,910 --> 00:01:55,920 distance you're traveling or you might 95 00:01:55,920 --> 00:01:57,590 distance you're traveling or you might measure your heart rate do you mind 96 00:01:57,590 --> 00:01:57,600 measure your heart rate do you mind 97 00:01:57,600 --> 00:02:00,920 measure your heart rate do you mind measuring something else the power 98 00:02:00,920 --> 00:02:00,930 measuring something else the power 99 00:02:00,930 --> 00:02:02,840 measuring something else the power output on the elliptical for example 100 00:02:02,840 --> 00:02:02,850 output on the elliptical for example 101 00:02:02,850 --> 00:02:05,149 output on the elliptical for example according to Matson it largely comes 102 00:02:05,149 --> 00:02:05,159 according to Matson it largely comes 103 00:02:05,159 --> 00:02:07,130 according to Matson it largely comes down to how well each machine calculates 104 00:02:07,130 --> 00:02:07,140 down to how well each machine calculates 105 00:02:07,140 --> 00:02:09,380 down to how well each machine calculates that power output which is a relatively 106 00:02:09,380 --> 00:02:09,390 that power output which is a relatively 107 00:02:09,390 --> 00:02:11,650 that power output which is a relatively reliable proxy for calories 108 00:02:11,650 --> 00:02:11,660 reliable proxy for calories 109 00:02:11,660 --> 00:02:13,990 reliable proxy for calories and the more complex a machine is so 110 00:02:13,990 --> 00:02:14,000 and the more complex a machine is so 111 00:02:14,000 --> 00:02:16,120 and the more complex a machine is so Stairmaster and a elliptical is more 112 00:02:16,120 --> 00:02:16,130 Stairmaster and a elliptical is more 113 00:02:16,130 --> 00:02:17,920 Stairmaster and a elliptical is more complex than a bike the less accurate 114 00:02:17,920 --> 00:02:17,930 complex than a bike the less accurate 115 00:02:17,930 --> 00:02:20,110 complex than a bike the less accurate the power output will be for one study 116 00:02:20,110 --> 00:02:20,120 the power output will be for one study 117 00:02:20,120 --> 00:02:21,970 the power output will be for one study researchers compared calorie readouts 118 00:02:21,970 --> 00:02:21,980 researchers compared calorie readouts 119 00:02:21,980 --> 00:02:23,740 researchers compared calorie readouts for ellipticals stair climbers 120 00:02:23,740 --> 00:02:23,750 for ellipticals stair climbers 121 00:02:23,750 --> 00:02:26,410 for ellipticals stair climbers stationary bikes and treadmills the 122 00:02:26,410 --> 00:02:26,420 stationary bikes and treadmills the 123 00:02:26,420 --> 00:02:28,480 stationary bikes and treadmills the calorie count on ellipticals was off by 124 00:02:28,480 --> 00:02:28,490 calorie count on ellipticals was off by 125 00:02:28,490 --> 00:02:31,210 calorie count on ellipticals was off by 42 percent while the other equipment had 126 00:02:31,210 --> 00:02:31,220 42 percent while the other equipment had 127 00:02:31,220 --> 00:02:32,980 42 percent while the other equipment had a noticeable but smaller margin of error 128 00:02:32,980 --> 00:02:32,990 a noticeable but smaller margin of error 129 00:02:32,990 --> 00:02:35,140 a noticeable but smaller margin of error now entering your weight before working 130 00:02:35,140 --> 00:02:35,150 now entering your weight before working 131 00:02:35,150 --> 00:02:36,940 now entering your weight before working out is a simple way to increase the 132 00:02:36,940 --> 00:02:36,950 out is a simple way to increase the 133 00:02:36,950 --> 00:02:38,680 out is a simple way to increase the accuracy and that's because different 134 00:02:38,680 --> 00:02:38,690 accuracy and that's because different 135 00:02:38,690 --> 00:02:40,630 accuracy and that's because different bodies burn calories at different rates 136 00:02:40,630 --> 00:02:40,640 bodies burn calories at different rates 137 00:02:40,640 --> 00:02:42,670 bodies burn calories at different rates even if they're doing the same activity 138 00:02:42,670 --> 00:02:42,680 even if they're doing the same activity 139 00:02:42,680 --> 00:02:45,160 even if they're doing the same activity but even if you do there's still plenty 140 00:02:45,160 --> 00:02:45,170 but even if you do there's still plenty 141 00:02:45,170 --> 00:02:46,300 but even if you do there's still plenty of room for error 142 00:02:46,300 --> 00:02:46,310 of room for error 143 00:02:46,310 --> 00:02:48,490 of room for error for example the machine might not be 144 00:02:48,490 --> 00:02:48,500 for example the machine might not be 145 00:02:48,500 --> 00:02:51,040 for example the machine might not be well calibrated the power output needs 146 00:02:51,040 --> 00:02:51,050 well calibrated the power output needs 147 00:02:51,050 --> 00:02:54,880 well calibrated the power output needs to be calibrated probably way more often 148 00:02:54,880 --> 00:02:54,890 to be calibrated probably way more often 149 00:02:54,890 --> 00:02:57,850 to be calibrated probably way more often than most of the the normal gyms are 150 00:02:57,850 --> 00:02:57,860 than most of the the normal gyms are 151 00:02:57,860 --> 00:02:59,890 than most of the the normal gyms are doing it today so if you're running on a 152 00:02:59,890 --> 00:02:59,900 doing it today so if you're running on a 153 00:02:59,900 --> 00:03:02,350 doing it today so if you're running on a treadmill if that treadmill is saying 154 00:03:02,350 --> 00:03:02,360 treadmill if that treadmill is saying 155 00:03:02,360 --> 00:03:04,090 treadmill if that treadmill is saying that you're doing 6 kilometers when you 156 00:03:04,090 --> 00:03:04,100 that you're doing 6 kilometers when you 157 00:03:04,100 --> 00:03:06,460 that you're doing 6 kilometers when you actually ran 5 that obviously the 158 00:03:06,460 --> 00:03:06,470 actually ran 5 that obviously the 159 00:03:06,470 --> 00:03:08,440 actually ran 5 that obviously the calorie count will be off and what about 160 00:03:08,440 --> 00:03:08,450 calorie count will be off and what about 161 00:03:08,450 --> 00:03:10,870 calorie count will be off and what about using heart rate monitors are those any 162 00:03:10,870 --> 00:03:10,880 using heart rate monitors are those any 163 00:03:10,880 --> 00:03:14,110 using heart rate monitors are those any better not really in a study published 164 00:03:14,110 --> 00:03:14,120 better not really in a study published 165 00:03:14,120 --> 00:03:17,110 better not really in a study published in 2017 Matson tested the calorie 166 00:03:17,110 --> 00:03:17,120 in 2017 Matson tested the calorie 167 00:03:17,120 --> 00:03:19,060 in 2017 Matson tested the calorie counters of several wrist porn monitors 168 00:03:19,060 --> 00:03:19,070 counters of several wrist porn monitors 169 00:03:19,070 --> 00:03:21,520 counters of several wrist porn monitors the most accurate one was off by an 170 00:03:21,520 --> 00:03:21,530 the most accurate one was off by an 171 00:03:21,530 --> 00:03:24,190 the most accurate one was off by an average of 27 percent and the least 172 00:03:24,190 --> 00:03:24,200 average of 27 percent and the least 173 00:03:24,200 --> 00:03:27,730 average of 27 percent and the least accurate it was off by a whopping 93% 174 00:03:27,730 --> 00:03:27,740 accurate it was off by a whopping 93% 175 00:03:27,740 --> 00:03:29,530 accurate it was off by a whopping 93% which can translate to hundreds of 176 00:03:29,530 --> 00:03:29,540 which can translate to hundreds of 177 00:03:29,540 --> 00:03:31,570 which can translate to hundreds of calories and those heart rate monitors 178 00:03:31,570 --> 00:03:31,580 calories and those heart rate monitors 179 00:03:31,580 --> 00:03:33,130 calories and those heart rate monitors built into exercise machines at the gym 180 00:03:33,130 --> 00:03:33,140 built into exercise machines at the gym 181 00:03:33,140 --> 00:03:36,280 built into exercise machines at the gym might be even worse he says now that's 182 00:03:36,280 --> 00:03:36,290 might be even worse he says now that's 183 00:03:36,290 --> 00:03:37,690 might be even worse he says now that's not to say you should ignore calorie 184 00:03:37,690 --> 00:03:37,700 not to say you should ignore calorie 185 00:03:37,700 --> 00:03:40,240 not to say you should ignore calorie

measuring your progress if you stick 188 00:03:42,100 --> 00:03:42,110 for measuring your progress if you stick 189 00:03:42,110 --> 00:03:44,229 for measuring your progress if you stick to the same

to get an accurate count 197 00:03:51,540 --> 00:03:59,990 unlikely to get an accurate count [Music]
