Think Well

Did you know that lofty goals are more likely to be achieved than super easy goals? 

Yes your brain likes, and needs challenge.

But how do you know if it’s too much? Or in my words. . . What is your Rate of Perceived Exertion with your goal efforts?  

I’m going to teach you how to use the Rate of Perceived Exertion scale we typically use in relation to exercise exertion in our goal efforts. Are you trying to lose weight? Do you have goals about eliminating your overeating at night? These are the types of goals we want to put through the RPE test and see where  they land. 

You’ll see how to measure your efforts and decide where to increase and where to decrease your efforts. 

I want you to reach your goals! If you aren’t, be sure to schedule a free strategy session with me so we can assess what’s going on. Goals too easy? Too difficult? Likely it’s the latter! But we’ll figure it out together.

00:00:00.000 --> 00:00:02.100
This is the Eat Well, Think Well, Live Well podcast.

00:00:02.129 --> 00:00:19.600
I'm Lisa Salsbury, and this is episode 61 rate of perceived exertion and your nutrition goals Welcome to Eat Well, Think Well, Live Well; the podcast for women who want to lose weight, but are tired of counting and calculating all the food.

00:00:20.230 --> 00:00:21.789
I'm your host, Lisa Salsbury.

00:00:22.179 --> 00:00:27.839
I'm a certified health and weight loss coach and life coach, and most importantly a recovered chronic dieter.

00:00:28.449 --> 00:00:34.390
I'll teach you to figure out why you are eating when you aren't hungry, instead of worrying so much about what you are eating.

00:00:36.079 --> 00:00:36.679
Hi everyone.

00:00:36.679 --> 00:00:39.259
I'm here with you today with a solo episode this week.

00:00:39.679 --> 00:00:45.978
So a couple of weeks ago, I moved my daughter into her college dorm.

00:00:46.368 --> 00:00:52.039
So that was all of those, you know, bittersweet kind of emotion, so fun for her.

00:00:52.039 --> 00:00:56.268
But anyway, I was in another state, far away from home, away from my routine.

00:00:56.268 --> 00:00:56.598
So.

00:00:57.018 --> 00:01:12.649
I decided to grab just a little day pass at a local fitness center in order to just get a workout in because there was, you know, a little bit of stress with all of the, all the college things and exercise does help me.

00:01:13.159 --> 00:01:14.388
Kind of relieve some of that stress.

00:01:14.388 --> 00:01:21.138
So I went to a local fitness center and took a spin class and I noticed on the wall, they had one of those posters.

00:01:21.739 --> 00:01:25.099
With the rate of perceived exertion.

00:01:25.429 --> 00:01:29.478
So this is a scale it's often abbreviated R P E.

00:01:29.899 --> 00:01:38.328
And this is a scale that you can use to measure you, the exertion you are creating, or, you know, measure your exertion.

00:01:38.629 --> 00:01:40.668
Without using a heart rate monitor.

00:01:40.668 --> 00:01:45.438
So instead of just saying, okay, we want to be at 80% of our heart rate, 80% of your max.

00:01:45.759 --> 00:01:51.578
The instructor might say, okay, I want you to be working at a four to six, or I want you to be working at a nine.

00:01:52.058 --> 00:02:01.718
So I it's kind of intriguing to me because of course, as you know, I do not use calories as a measure of my food intake, but rather I use a hunger scale.

00:02:01.718 --> 00:02:02.259
And so I was.

00:02:02.799 --> 00:02:12.878
Thinking about this rate of perceived exertion as a measure for something that, that we do have numbers for, we could just use our heart rate monitor, but this is a pretty common tool.

00:02:13.122 --> 00:02:20.051
So I'm going to go over it a little bit with you levels, go from one to 10, with 10 being the hardest.

00:02:20.081 --> 00:02:22.722
So one is considered very light activity.

00:02:22.873 --> 00:02:23.653
That's its title.

00:02:23.894 --> 00:02:26.924
Hardly any exertion, but more than sleeping.

00:02:27.433 --> 00:02:28.783
Slow walk, et cetera.

00:02:29.175 --> 00:02:36.705
Then it goes two to three that's light activity feels like you can maintain for hours easy to breathe and carry a conversation.

00:02:36.985 --> 00:02:38.634
And I'm just reading you what the chart says.

00:02:38.634 --> 00:02:40.974
So if you're familiar with this, it's going to sound very familiar.

00:02:41.365 --> 00:02:41.514
Okay.

00:02:41.514 --> 00:02:45.715
The next one is considered moderate activity and this is between four and six.

00:02:45.715 --> 00:02:50.004
So this is three numbers in that center section of the one to 10 scale.

00:02:50.004 --> 00:02:51.805
So four to six is moderate activity.

00:02:52.134 --> 00:02:59.034
Breathing heavily can hold a short conversation, still somewhat comfortable, but becoming noticeably more challenging.

00:02:59.034 --> 00:03:00.384
I really want you to remember that one.

00:03:00.384 --> 00:03:01.014
It's really good.

00:03:01.405 --> 00:03:01.645
Okay.

00:03:01.645 --> 00:03:03.474
Seven to eight vigorous activity.

00:03:03.685 --> 00:03:05.125
Borderline uncomfortable.

00:03:05.125 --> 00:03:07.525
Short of breath can speak a sentence.

00:03:07.944 --> 00:03:10.854
Nine is very hard activity.

00:03:11.125 --> 00:03:13.014
Very difficult to maintain exercise.

00:03:13.014 --> 00:03:15.264
Intensity can barely breathe and speak.

00:03:15.294 --> 00:03:17.004
Only a few words.

00:03:17.514 --> 00:03:26.905
And number 10 is the max effort activity feels almost impossible to keep going completely out of breath, unable to talk.

00:03:27.235 --> 00:03:30.835
Cannot maintain for more than a very short time.

00:03:31.495 --> 00:03:31.914
Okay.

00:03:31.995 --> 00:03:37.346
So chart really helps you to measure your physical exertion.

00:03:37.705 --> 00:03:43.406
But I got to thinking about the effort that it takes to make changes in your life.

00:03:43.765 --> 00:03:46.316
How do we measure that effort?

00:03:46.825 --> 00:03:52.195
And it's funny when you start thinking about something, you start seeing it all over the place.

00:03:52.225 --> 00:03:57.895
Just like when you're thinking about buying a new particular car, then those are the only cars you see on the road.

00:03:57.895 --> 00:03:58.286
Right?

00:03:58.705 --> 00:04:07.556
So shortly after I saw this chart and started mulling over this perceived effort rate of perceived effort, I was listening to the human lab podcast.

00:04:07.885 --> 00:04:12.925
And it was an episode called goals, toolkit how to set and achieve your goals.

00:04:13.466 --> 00:04:16.975
He was talking about the effort required to achieve a goal.

00:04:17.425 --> 00:04:21.055
I listened to it again and took down what he said.

00:04:21.055 --> 00:04:23.485
So this is basically going to be a quote, right?

00:04:23.485 --> 00:04:24.716
From that podcast.

00:04:25.045 --> 00:04:30.896
He said, how lofty your goal is, will impact how likely you are to achieve it.

00:04:31.286 --> 00:04:36.656
Most people believe that the easier your goal is the more likely you are to achieve it.

00:04:36.836 --> 00:04:39.115
But the opposite is shown to be true.

00:04:39.716 --> 00:04:55.105
If a goal is too easy to achieve it, doesn't recruit sufficient amounts of the arousal network that involves the amygdala and a bunch of other brain structures that get people into the necessary actions to continually pursue that goal.

00:04:55.466 --> 00:04:59.245
This perhaps should not be surprising in order to learn something.

00:04:59.485 --> 00:05:03.985
We have to shift the nervous system into states that are somewhat uncomfortable.

00:05:04.406 --> 00:05:09.235
These should be safely uncomfortable states, but they should be uncomfortable.

00:05:09.685 --> 00:05:14.305
Any kind of successful learning or goal pursuit is going to involve errors.

00:05:14.636 --> 00:05:16.706
It's going to involve failures.

00:05:17.036 --> 00:05:18.776
It's going to involve frustration.

00:05:19.165 --> 00:05:21.146
It's going to involve anxiety.

00:05:21.716 --> 00:05:26.966
All of those states of mind and body shift the brain into modes of neuro-plasticity.

00:05:27.415 --> 00:05:29.276
They give it the ability to change.

00:05:29.576 --> 00:05:40.375
And that should make perfect sense because if you can complete what you want easily, there's absolutely no reason for the neural circuitry to shift in any way.

00:05:40.706 --> 00:05:41.516
Why would it.

00:05:42.175 --> 00:05:52.386
Rather those states have discomfort, frustration, anxiety, et cetera, represent shifts in neurochemical states that literally opened the opportunity.

00:05:52.656 --> 00:05:55.206
For neuroplasticity to occur.

00:05:55.865 --> 00:05:57.696
So fascinating.

00:05:57.725 --> 00:05:58.026
Right?

00:05:58.026 --> 00:06:07.985
This is so fascinating to me because you can liken this directly to exerting effort on the body and the muscular system or cardiovascular system to induce.

00:06:08.286 --> 00:06:08.886
Change.

00:06:09.156 --> 00:06:12.485
We have to work our bodies at some level of discomfort.

00:06:12.755 --> 00:06:14.136
To create change.

00:06:14.406 --> 00:06:31.925
So if we go back to that RPE chart, if you're working at a one very light activity or two to three light activity, remember that's something you can maintain four hours, you are unlikely to be creating any real change in the muscular system or the cardiovascular system.

00:06:32.346 --> 00:06:37.235
It's not laying on the couch, but it's also not really working hard.

00:06:37.716 --> 00:06:42.485
We want to be in that four to six moderate activity at least.

00:06:42.786 --> 00:06:45.125
To start seeing some changes in the body.

00:06:45.935 --> 00:06:46.415
But.

00:06:47.076 --> 00:06:55.315
This four to six moderate activity is also described as Still somewhat comfortable, but becoming noticeably more challenging.

00:06:55.855 --> 00:06:59.365
If you work at that four to six level every day for several weeks.

00:06:59.663 --> 00:07:07.463
this level of activity that created this challenge in the beginning is going to start feeling like light activity like that two to three range.

00:07:07.822 --> 00:07:15.773
So if we shift this to talking about our eating habits, this is where I think it gets really interesting is to use.

00:07:16.163 --> 00:07:18.473
This rate of perceived exertion.

00:07:18.670 --> 00:07:22.329
To achieve our goals in changing our eating habits.

00:07:22.360 --> 00:07:30.100
And of course this could be with any goal that you have, you don't have to just confine it to our eating habits.

00:07:30.129 --> 00:07:31.120
It's just that.

00:07:31.149 --> 00:07:44.860
Uh, for me, the most common goal that my clients come to me with is to change the way they are eating in some way, whether that's to eat less because they're tired of constantly feeling overly full or to change the types of foods they are eating.

00:07:45.250 --> 00:07:48.430
Or they want to have a healthy relationship to food.

00:07:48.430 --> 00:07:49.360
So they.

00:07:49.990 --> 00:07:55.000
Are not eating in order to comfort their emotions on a consistent basis.

00:07:55.000 --> 00:07:55.420
Right.

00:07:55.899 --> 00:07:56.410
Okay.

00:07:56.692 --> 00:08:06.262
let's just say the goal is to stop overeating just because that is a simple phrase that encompasses all these types of eating behaviors that you might want to create.

00:08:06.502 --> 00:08:13.701
So maybe you're thinking I'd like to eat less sugar, or I'd like to go to bed feeling light and not bloated and distended in my stomach or.

00:08:14.002 --> 00:08:14.932
I want to sleep better.

00:08:14.932 --> 00:08:19.401
And that means not going to bed with a lot of food in my stomach, because that disturbs my sleep.

00:08:19.791 --> 00:08:24.682
Maybe you want to stop eating at the end of the day to unwind or decompress as a reward.

00:08:24.831 --> 00:08:29.151
So all of that, we could just sum up with the idea that we want to stop overeating.

00:08:29.572 --> 00:08:29.841
Okay.

00:08:29.841 --> 00:08:32.272
So if your goal then is to not over eat.

00:08:32.692 --> 00:08:34.912
During breakfast on Thursday morning.

00:08:35.631 --> 00:08:39.831
That's feeling like a one on the rate of perceived exertion, right?

00:08:39.831 --> 00:08:41.782
That's very light activity.

00:08:41.991 --> 00:08:44.572
There's hardly any exertion to do that.

00:08:44.991 --> 00:08:47.182
Like the definition, it's more than sleeping.

00:08:47.572 --> 00:08:49.611
But it's just a slow walk.

00:08:50.481 --> 00:08:55.491
So if you decide, okay, I'm not going to overeat all breakfasts and lunches this week.

00:08:56.121 --> 00:09:03.022
You're maybe feeling like maybe you're at a three now, typically for my clients, breakfast and lunch, aren't really they're challenging meals.

00:09:03.052 --> 00:09:09.201
I even have one client last week that she told me she doesn't write down breakfast anymore because she says she's got it on lock.

00:09:09.501 --> 00:09:10.761
Like, it's so easy for her.

00:09:10.761 --> 00:09:14.481
It's probably less than a one effort because it's on autopilot.

00:09:14.511 --> 00:09:17.572
So including breakfast and lunch in this goal.

00:09:17.991 --> 00:09:20.302
Maybe that's bringing it up to a three.

00:09:20.662 --> 00:09:21.351
Effort.

00:09:22.131 --> 00:09:29.871
But if we are needing to recruit that arousal network to work at a rate that feels challenging enough to be worth the effort.

00:09:30.412 --> 00:09:35.841
We probably want to be working at this goal at a rate of perceived exertion of four to six.

00:09:35.871 --> 00:09:38.812
Remember how I told you when I was reading the chart, like.

00:09:38.846 --> 00:09:41.187
Commit this part to memory this moderate activity.

00:09:41.187 --> 00:09:42.986
I'm going to read you the definition of this again.

00:09:42.986 --> 00:09:46.226
And of course, this again is for your physical exertion.

00:09:46.466 --> 00:09:49.496
Breathing heavily can hold a short conversation.

00:09:49.826 --> 00:09:54.326
Still somewhat comfortable, but becoming more challenging.

00:09:55.226 --> 00:10:00.596
This is where we want to kind of aim to work at our goal.

00:10:00.626 --> 00:10:08.157
What is going to feel like that amount of effort it's still somewhat comfortable, meaning it's sustainable for a very long while.

00:10:08.456 --> 00:10:14.336
But it's going to be challenging enough to incur some amount of neuro-plasticity change.

00:10:14.907 --> 00:10:15.236
Okay.

00:10:15.267 --> 00:10:22.917
Now, if we keep going, we get into what I kind of think of as short term diets and bootcamp type efforts.

00:10:23.187 --> 00:10:28.136
So have you ever done one of those like six week boot camps or diets that are so difficult?

00:10:28.136 --> 00:10:30.506
You can only do it for a few weeks.

00:10:31.226 --> 00:10:35.606
These are the type that make you cut out several of your favorite foods or entire food groups.

00:10:35.937 --> 00:10:40.346
You have to research menus and make all your own food from scratch three or four times a day.

00:10:40.346 --> 00:10:43.466
You have to shop for special ingredients and make special combinations of food.

00:10:43.616 --> 00:10:44.547
Does this sound familiar?

00:10:44.606 --> 00:10:45.326
Is this just me?

00:10:45.746 --> 00:10:48.777
I may or may not be speaking from experience here.

00:10:48.836 --> 00:10:49.557
Of course I am.

00:10:50.006 --> 00:10:55.167
Anyway, this is like, That nine level of hard, very hard activity.

00:10:55.407 --> 00:10:57.447
It's very difficult to maintain.

00:10:57.746 --> 00:11:01.317
You can barely breathe or think about anything else.

00:11:01.942 --> 00:11:06.383
Can you get a sense of what I mean by this rate of perceived exertion?

00:11:06.383 --> 00:11:10.533
When you're thinking about the way we're approaching the changing or the way we're eating.

00:11:11.523 --> 00:11:21.363
You may have even tried to change your habits at a full 10 max effort activity feels almost impossible to keep going and you can't maintain it for more than a very short time.

00:11:22.113 --> 00:11:27.153
These types of monumental efforts on your goals can have some impact on changing your brain.

00:11:27.153 --> 00:11:32.613
But if you're anything like me, the change that's made on my brain is like, ah, never do that again.

00:11:33.452 --> 00:11:39.482
It's not maintainable for long enough to create any real meaningful lifestyle change.

00:11:40.143 --> 00:11:43.143
I pretty consistently coach on the difference between diets.

00:11:43.472 --> 00:11:44.852
And lifestyle changes.

00:11:45.423 --> 00:11:51.722
I think the rate of perceived exertion scale could be applied here to determine what you are doing.

00:11:52.322 --> 00:12:04.533
If your RPE feels like above a moderate activity above a five or a six, you are most likely on a short-term diet that is not sustainable for any length of time.

00:12:05.523 --> 00:12:12.243
If you are attempting, if what you are attempting is feeling challenging enough to keep your brain engaged and interested.

00:12:12.692 --> 00:12:15.692
But also doable enough to maintain for the long run.

00:12:16.082 --> 00:12:19.202
You are most likely creating lifestyle changes.

00:12:19.533 --> 00:12:31.113
You are probably working somewhere in that four to six range of rate of perceived exertion, depending on the day, depending even maybe on the meal, like breakfast is so easy, maybe for you.

00:12:31.113 --> 00:12:35.913
It's easier on the effort, but it might be more challenging to listen to your physical fullness cues at dinner.

00:12:36.482 --> 00:12:38.163
It is okay to be challenged.

00:12:38.613 --> 00:12:39.182
It's okay.

00:12:39.182 --> 00:12:40.442
For things to be difficult.

00:12:40.773 --> 00:12:44.643
We want to feel these things to stay engaged with the goal.

00:12:44.722 --> 00:12:46.732
but it must feel doable.

00:12:47.722 --> 00:12:52.102
So in practice for this week, you could experiment with your food journal.

00:12:52.462 --> 00:13:03.113
If you are planning your meals ahead for the day, you could look at your plan and ask yourself what is the effort on the RPE scale that this plan will take for me today.

00:13:03.442 --> 00:13:07.133
If it's a walk in the park, you may want to challenge yourself a bit more.

00:13:07.582 --> 00:13:13.253
If it looks like it's going to be a nine effort, then you likely need to change it up and scale back a little.

00:13:13.913 --> 00:13:16.253
You also want to take into account your day.

00:13:16.493 --> 00:13:32.873
And other stressors that you're going to have if you were working on a weight loss school, but today you also have a parent teacher conference, a work presentation, and you need to get supplies to pack lunches for tomorrow because you're completely out of bread, but your food plan looks like it's a two on the RPE.

00:13:33.082 --> 00:13:33.923
That's perfect.

00:13:34.822 --> 00:13:41.812
If you already have a really light day stress-wise you could challenge yourself a little more on the weight loss goal part.

00:13:42.173 --> 00:13:44.273
Anytime you're adding something in though.

00:13:44.273 --> 00:13:47.753
Say maybe you want to start incorporating new vegetables into your routine.

00:13:48.503 --> 00:13:54.743
Purchasing a juicer and making a fresh green juice every morning would run me like an eight or a nine on the RPE scale.

00:13:55.043 --> 00:13:58.342
So that's something I'm unlikely to stick with for very long.

00:13:58.883 --> 00:14:01.373
But deciding I'm going to try one new vegetable.

00:14:01.373 --> 00:14:04.942
Each time I go to the grocery store and figure out how to prepare it and eat it.

00:14:05.243 --> 00:14:08.753
That's more like a five on my RPE that I can do.

00:14:08.842 --> 00:14:15.533
And to be honest, I did that and now I eat several more types of vegetables than I used to before running that experiment.

00:14:15.952 --> 00:14:21.802
it was just challenging enough that I stuck with it until I felt like I had tried all the new veggies I could.

00:14:22.222 --> 00:14:25.643
And I had incorporated several into our regular rotation.

00:14:26.153 --> 00:14:27.952
The juicer is still in the cabinet.

00:14:28.043 --> 00:14:32.332
It gets pulled out occasionally, but way less often than I eat Brussels sprouts.

00:14:33.143 --> 00:14:38.273
So give yourself a break from the nine or 10, very hard and max effort this week.

00:14:38.602 --> 00:14:44.962
But also keep up the challenge enough to stay interested and create that change.

00:14:44.993 --> 00:14:46.043
You're looking for.

00:14:46.673 --> 00:14:48.052
Let me know how this goes for you.

00:14:48.293 --> 00:14:56.243
If you tend to set easy goals that you can't stay motivated or interested in, or more likely, you're probably setting unrealistically difficult goals.

00:14:56.543 --> 00:14:59.722
Let me help schedule a free strategy session.

00:14:59.735 --> 00:15:06.785
With me and see if coaching is the missing piece of your weight loss puzzle link for that, of course, is in the show notes.

00:15:06.846 --> 00:15:07.625
Have a great week.

00:15:07.625 --> 00:15:10.836
