Allowed calorie intake...?
Hello again
Thank you to those that have helped me so far but can anyone advice me a little more now on this.... http://www.tiscali.co.uk/reference/h...rie_guide.html I seem to find different opinions on the amount of calories needed to sustain a person. For instance according to the above I should have 3100 calories and yet on other websites I have found information varying from 2100 to 2500. So although I assume "averages" are being used is there a concensus of opinion on what a persons daily calorific intake should amount to...? Thanks Bob |

s.com... Hello again Thank you to those that have helped me so far but can anyone advice me a little more now on this.... http://www.tiscali.co.uk/reference/h...rie_guide.html I seem to find different opinions on the amount of calories needed to sustain a person. That's because it's very hard to come with a number that will be the right one for YOU! Except for pluging you to a device that will calculate how much oxygen you burn, there is no way to know exactly how many calories you need. You can search for my posts and others in the "calories per day" thread about that. So, each site has its own formula, which they believe is the best. Also, each site has its own definition of what exactly is "light" or "moderate" activity, and you probably have your own as well, which is usually over-evaluated That's why some people, myself included, suggest that you just eat your regular amount of food for a week or so (I think balancing caloric intake on the week rather than the day is both more accurate and flexible) while writing down everything you eat. Then, you can calculate how many calories you have been eating, and, assuming you were naturally maintaining weight, that will be a much better estimation than any site can come with. Then, you can lower than amount *a bit*, like removing 300-400 calories from it and see what happans during the next week or so. Rinse&repeat until you find something you are comfortable with, both in term of hunger and weight loss (3lbs per week is a max), only doing *little* changes at a time. Another strategy is to use your hunger and satiety as a clue, if these signals are still good quality for you. Your brain gathers information from all around your body and computers them. It knows your body fat better than any tanita scale, it knows how many calories have been made available from food... Then, it does all the computation and just switches on the green light to tell you to eat, and the red light to tell you to stop - hunger and satiety. For many people, this mechanism is pretty messed up because they have learnt to ignore it (diets, eating disorders, in a few cases metabolic problems...). But if it still works for you, or if you can tune to it again, that's probably the most accurate way of managing your caloric intake. |

So although I assume "averages" are being used is there a concensus of opinion on what a persons daily calorific intake should amount to...? Thanks Bob Most of those formulas are based on certain assumptions that may or may not be true for you. I agree with what Lictor posted, and think that the whole focus on calorie counting is difficult and error prone. It's hard to accurately count calories in what we eat. And, even if you do, that's only the "in" side of the equation. If I eat 2000 calories on Friday and 3000 calories on Saturday...what does that mean? If I spent Friday sitting at the computer, but rode my bike 40 miles on Saturday, I probably lost more weight on Saturday. Unfortunately, as hard as it is to count the calories "in", counting the calories "out" with any degree of accuracy is next to impossible. From what I've read on the subject, the key to weight loss is to achieve a daily caloric deficit of around 500 calories per day (which will yield about 1 lb of weight loss per week). But, how do you do that given the difficulties of counting calories in and out? While researching this, I realized that my digital scale could provide some answers. So, I started weighing myself every day. But, after doing this for a while, I noticed a problem...weight changes quite a bit from day to day. Variations of 2-4 pounds are not uncommon (due to many natural causes, in addition to that container of Haagen-Dasz!). Fortunately, the problem of "variability" in data has been addressed in other fields. Scientists and stock market analysts use a technique called "linear regression" to filter out the daily ups and downs in their data. So, I decided to write a program to do this for weight management. It's a weight and health diary called "WeightWare" (http://www.WeightWare.com). It includes tools to assess your current weight, set reasonable weight goals, and track your progress. The key feature, however, is the automatic calculation of your "Weight Trend". Using the linear regression calculations, this will tell you exactly how much weight you are losing or gaining per week, along with your calculated daily calorie deficit (or surplus). These important numbers are derived solely from your weight, not from counting calories. I'm hopeful that it can be a useful tool in weight management (it's helped me get to my lowest weight in 15 years). You can download a free, fully functional 45-day trial version from the website to see if it meets your needs. Sorry for the somewhat lengthy plug, but I've been working really hard on this program, and just officially released it this morning (yeah!). -- GG http://www.WeightWare.com Your Weight and Health Diary |

Allowed calorie intake...?
I doubt anybody is going to maintain weight
after losing on 3100 calories unless they are working at a heavily physical job plus exercising in a lot of their spare time. 2000 IIRC is based on at least 30 straight minutes of moderate physical activity a day. Needlework (my passion) or office work like using a computer doesn't qualify as moderate, that is why as more and more people do office work the population gets more and more obese -- in their spare time they are not working out but watching TV. Beverly probably has better data. "Bob" wrote in message s.com...

For instance according to the above I should have 3100 calories and yet on other websites I have found information varying from 2100 to 2500. continuing from my reply to Gary G's post in this thread... a) read the Hacker's Diet http://www.fourmilab.ch/hackdiet/www/hackdiet.html There's a lot of good wisdom on dieting in this book. So although I assume "averages" are being used is there a concensus of opinion on what a persons daily calorific intake should amount to...? You'll need to find this by trial and error. Me, I was on a stable weight for most of 2003 (after cutting out the Mt Dew), so I just figured cutting about 1000 kcal out would give me the 1000 kcal/day deficit I needed. But the important thing (for me at least) is to INSTRUMENT your daily diet. I've been updating a worksheet in Excel daily for this. Every day I enter my weight, and the spreadsheet does the rest: Eg. today says: Weight: 206.5 (this is the actual scale weight I type in) Averaged Weight: 208.4 (this is the running average, see below) Daily Gain/Loss Trend: -0.624 (today's average - yesterday's average) Gain/Loss Delta: +0.338 (the Gain/Loss number - my desired loss rate, which is 0.286 lbs/day) Over: 26.4 (how many lbs I'm over my goal weight of 182) Goal %: 45.1% (how far I am toward my goal weight) BMI: 27.49 (current BMI) (plus 2 more numbers that I'll keep proprietary for now, since they're a pretty nifty innovation that I tempted to patent LOL). Anyway, the most important number is the Averaged Weight, since it provides a pretty good estimate of your true weight even as it goes up & down each day due to daily fluctuations. The averaging calculation is pretty simple: Today's average = yesterday's average + (today's weight - yesterday's average ) * 0.25 So basically if I drop a lb today, the average will drop 0.25. If I gain a 2 lbs for some reason, the average will only rise 0.5. This provides a smoothing effect for the daily numbers that really helps keep a good picture of your weight loss when graphed; see Gary G's website for how the graphs look, or he http://www.fourmilab.ch/hackdiet/www...000000 000000 I heartily recommend Gary's product, for while I haven't used it it's doing exactly what I'm doing with Excel, and for $25 it seems like a good deal. |

You can do a free assessment in this site (no need to be a member or to
submit your e-mail address to the site). The results are displayed in a java-script pop-up window. http://www.caloriescount.com/ That's where I found out how many calories I needed to consume a day in order to lose weight. Good luck.

There's far too much software out there that is dreck from this perspective. I was very impressed with the breadth of your design. I had spent a week or so on & off thinking about the program, but your app really covered all the bases well. If you're working on a point release, I'd recommend: + plotting the expected loss rate on the graph too. This is what I use most to correlate progress (or lack thereof) with calorie deficts. + if you plot the expected rate loss, you will have to support variable loss rates, since it is common to switch gears on a diet (partway in I went from 875 kcal/day deficit to 1000 kcal/day, but perhaps later I might want to start backing off a bit in a month or two). +Your trend plotting is very linear; I think too much information is being lost with your function. I prefer John Walker's formula (with a 0.75 smoothing factor), since it is more usable on a day-to-day basis. + minor UI thing on the calendar, the weekly summary cells should not be so similar to the out-of-month cells. I'd also color-code 'up' days in red, to better signal them. |
