Hey guys!
I was procrastinating at work and found this webpage that was helpful and interesting to me:
http://www.shape.com/weight-loss/weight-loss-strategies/ask-diet-doctor-how-many-calories-should-i-eat-lose-weight
It basically explains the how and why on calculating how many calories you should be eating to lose weight.
The writer is "Dr. Mike Roussell, PhD, nutritional consultant" so I think he may have some merit
It says to calculate and then try it out for two weeks and monitor your weight to see how your plan working for you.
I think we all have 2 weeks we can spare to try something different. Give it a shot! I hope it helps some of you out! Don't be afraid to try what you calculate for yourself. 2 weeks is nothing in the grand sceme of things.
It calculated about 200 additional calories for me to eat than I have right now, so I think I'll try it .
Good luck! :flowerforyou:

Wow! I used the formula and it says I should be eating 2006 calories a day! Thats 500 more calories a day for me. I just cant bring myself to eat that many calories.0
-
So basically as i'm "Lightly Active".
BMR (1850) * 1.5 - Defecit(1000) = 1775 calories/day (NET)
Thats pretty much what i'm doing....0 -

I know, it seems strange! Did you reduce 500 calories or 250 from your "maintainence" calories? I subtracted 500 to put me at 1726 a day.
But eating more does help you lose weight (depending on certain factors, of course), so I'm certainly not afraid to try it out for the full 2 weeks. It can't hurt!0 -
Uses a basic multiplier for calculating TDEE. That is insufficient for fine tuning.
If you do not engage in the SAME exact activities per day, then your TDEE changes each day. This is why some, such as myself, argue for using MFP's guidelines to go by sedentary activity level and then log your activities in via exercise to more accurately get the count for that day.0 -

Good! That's easy then lol
The calculations from that site were pretty different from what I had on MFP, so it was interesting to me. Plus it was nice to read through the explanation for it all.0 -

That makes sense..0 -
This is exactly the same thing as MFP uses, so how is it different? I don't understand how this is so significantly different for anyone? And then it's 500 calories less per day for each pound you want to lose, which is exactly the same as it says in the article...0

I think it made a difference for me because of the "lifestyle" option. In MFP I am Sedentary according to the discription that MFP provides, but with this website's explanation I calculated as "Lightly Active". It just worded things in a way that helped me calculate a bit more specifically.0 -
I see what you're saying - well, this also differs depending on who is describing it to you, but it doesn't change the formula.
Search for Harris Benedict equation and you will see how many different definitions there are of the difference between sedentary and lightly active. Many sites describe lightly active as "light exercise/sports 1-3 days/week" instead. Which to me means, that if I choose sedentary and log all my exercise instead of relying on the fact that I'll get a bit of exercise in during the week, I can fine tune things a lot more. That said, I am going to have to move up to lightly active soon, because I run up and down the stairs at work now every day (because I CAN!!) and make a point of walking on escalators instead of standing etc.
Either way, it's the same formula, just the "description" of what it means differs. Doesn't mean the guy is right though...0 -

No no you're totally correct. Like I said originally, it was just nice to read through the description of the formula and blah blah blah.
You're right, the definition of active is different everywhere but the provided formula is still the same, so it does depend on what your personal goals and/or regular activities are to find what fine tuning you need to calculate

And congrats on this btw!!0 -
I ran the numbers and got pretty much what I'm working with now. I'm doing TDEE minus a 15 to 20 percent deficit. But it's great to have it re-affirmed:)))0
-
No no, YOU'RE totally correctNo no you're totally correct.
But you have a point. Two weeks is nothing to try a different setting in the bigger scheme of things. Doing this isn't a quick fix and if you end up not losing anything for two weeks, at least you know that your activity is closer to sedentary...
I am going to have to start tweaking soon...but it is scary every time I do!! (I do not change goals or settings on any day other than a Monday when I also weigh in...).
In the end though, a two weeks change of settings could mean that you understand your body better, which is probably worth more than losing a few pounds (and hopefully you'll still lose some too).0 -
I've been logging here for 20 days, averaging 1700-ish calories a day, and no weight loss yet. That Shape article calculated me at a little over 2,100 to lose a lb a week. I don't want to risk gaining any more weight, so I'll pass on that.
Hope it works out for you!0 -
Interesting. It came out to pretty much what I'm doing now.
BMR = 1678.35
w/activity level = 2517.525 (-1000
Calorie Goal = 1518 (which is only 198 more than MFP gives me)
However I don't lose anywhere near 1-2 lbs a week - so likely to actually lose according to this I should try subtracting another 250 from my goal which would be 1268 as my actual calorie goal (which is only 52 less than MFP gives me).
Okay this was too much math and it seems to me like no miracles are going to happen if I eat 52 calories less a day - so moving on.... I'm going to print it for later though so I can do the math again later - right now I'm having a hard enough time staying in the green on calories and am really frustrated and tired and hungry but I know I'll have to make a serious cut to calories soon if I ever want to reach my goals.0 -
I chose 1.4 (sedentary since I only work out three days a week and would add that separately). It says I need 2,259 to maintain. That seems awfully high.
ETA: My BMR was 1613...0 -
um i just worked mine out using this and it seems very low, it tells me for my body to maintain i should eat 1677.69 and to loose subtract 500 which means id only be eating 1177.69 per day, i cant survive on that. but if this is correct i need to lower my cals as ive been equally around 1400 - 1600 a day........0

Mine comes out the same too, just 150 calories different.0 -

YES! I run up and down stairs now too, just like a kid! (I used to always run stairs as a kid because it took WAY to long to walk. I also used to run home from school for the same reason, just impatience.)0 -

Yup. I got a very similar amount when I did it. Funny cos I'm losing fat but not s ale weight on between 1700 and 2000 a day. Maybe I'm a freak? I don't know, but according to that I should be gaining!0 -
I don't think this calculation works well for larger people. It says I need to eat 3,150 calories a day to maintain my current weight. I would be packing on pounds like mad if I ate that much.0
-
This will produce .5-1lb not 1-2 as per week if that is all you want go for it and eat more.0

Not necessarily. I was eating 4000 calories to gain weight. You weren't tracking your food as you got heavy, now were you? I tracked a typical day (not a binge day, mind you, just a normal day) when I first started and was shocked at the calories.0 -
I tried the formula to see what number it would spit out. I think it's important to remember that these are probably based on averages. I've had a full metabolic workup by a medical professional and what they came up with is actually 300 less than the number the formula on the website produced. I happen to have a slow metabolism and that is something that online formulas probably don't take into account. Unless you're smack in the middle of average I think most everything you find online is not necessarily applicable to most people. It really depends on your endocrine system.
If you haven't had a full metabolic workup it's probably good to just experiment with different caloric intakes and see what works for you, as an individual.0 -
my mpf calorie set goal is about right compared to this article.0
-
oh errrr, my bad my calculations were wrong, I was trying to do it on my iphone whilst also reading the thread, not possible obviously lol. The correct calculations were actually pretty spot on for what i'm eating now. All good ;-)0
-
Interesting. I did the calculations and it's about right to what I've been doing (which is NOT what MFP set me up at) and I have finally lost 3 pounds after making the change, which was to increase my calories. This has me at a maintenance of about 2000 calories so if I take 500 off, that puts me at 1500 which is what I've been doing plus eating back some of my exercise calories. I have less than 25lbs to lose though so I probably should only be taking 250 off each day.0
-
According to this I should be at about 1700 calories a day to lose a pound a week (which I don't usually lose a pound a week). Instead I have MFP set for 1400 and then add in exercise calories, but I've always known 1700 a day is OK, so I don't fret if I go upt hat high even if MFP puts me in the red. The thing is, over the last three months I've sucessfully managed to shrink my appetite back down to what it was almost 10 years ago (when I was skinny), so without eating total junk (which I still do more than I should), 1400 calories is hard for me to hit. On days when I am truly eating healthy and not giving myself sweet or junk treats, I'm full all day by 1000 calories. Sometimes I will MAKE myself down a protein shake anyway since I'm always low on protein, but if I'm eating my correct portions of fruits and veggies and drinking my correct amount of water in a day, 1400 is way more than I can eat.0

Did you multiple that by 1.4 or 1.5? It doesn't seem like you did. Maybe you did the first part of the equation but not the second. You probably calculated only your BMR.0
