How Do Weight Watchers Calculate this

Ladywriter1968

I found a weight watcher calculator, where you put in your height weight etc, and it works out how many pro plus weight watcher points you can have each week, but I am curious as to how they worked this out mathematically.

Female
Age 42
Height CM 172
Weight 76.2KL
Pro Points per day 29 = answer.

So they base it on your
Sex
Age
Height
Weight
and then come up with the answer 29

I notice they also use the metric system so I converted it all from my stones and pounds and inches and feet. Into metric above as this is the way weight watcher do it.

I wondered if any maths experts out there could give me the formula of how they come up with the answer 29?
Please don't give me algebra cause I find that rather complicated. simple form will do. Thanks. things like algebra and logarithms etc I have never been any good at.

This is the site if you want to calculator yours quickly, or maybe you are on have done weight watchers. I took information above from the site.

Ponts, schmoints...sounds very unscientific to me! You would be better calculating your basal metabolic rate.

I don't think we can answer that. I think they take your details and calculate the amount of food, or more likely calories, you should consume in a day, then convert that into points.

So, unless we know how they convert calories into points, we can't find out how to calculate how many a person needs.

It would go something like this

Female
Age 42
Height CM 172
Weight 76.2KL
Needs 2,900 calories per day
2,900 calories = 29 pro points
Pro Points per day 29 = answer.

Just about everyone gets 29 and then 49 extra for the week. It favours protein over carbs. I think the plan is good- it is not just calories, but is sort of low GI.

I'm at weight watchers and I get 36 points at the moment as I have such a lot to lose. Everyone also gets the 49 points a week to splurge with.

29 is the lowest number of points they go to (+ the 49) If you go to a class they say its a calculation on how your body processes the food rather than a straight calorie count. Probably a load of psudo-science twaddle but if it works for some of us I'll go along with it.

I've lost 13.5 in 6 weeks so it's not too bad.

I have been going to Rosemary Conley - no pseudo-science. Just good old fashioned common sense. Eat sensibly, with portion control, avoid high-fat foods, and get exercising. I have a calorie allowance for each meal time so that keeps me in check, even now when I'm not dieting. It's just a guide to keep me eating sensibly. Also I don't have to rely on buying products with points allocations or checking in books, because all things have calories written on the side. It's an easy way of knowing where you are.

I lost 4 1/2 stone within 9 months just by following those principles. And a year and a half later I am still the same size. no yo-yo dieting. Whilst I have had my indulgences here and there, like Christmas, ultimately I keep going back to common sense eating and exercising and snap back into shape really quickly. The class fee includes an exercise class so I feel like I'm getting my money's worth.

Whilst the points idea might work for some people who tune into it, I like to know the workings behind things. One pound of fat is worth 3,500 calories. To lose one pound of fat, you have to burn more than 3,500 calories off your body over what you eat. Eat sensibly and exercise, you can lose around 2 pound a week. It seems really logical and it made complete sense to me. Everything seemed to click into place. It means now I like making healthier options and see indulgences as a lovely treat, not a habit. I think when something makes sense to you, it will work and if it works, stick to it!

I don't know how they work out the pro points allowance but it isn't based on calories as that was the big thing when they launched the plan - that they had ditched the calories. When you work out the pro points value of a food, it's based on the protein, carbs, fat and fibre in the product.

I've been on ww for almost a year. Since the pro points were introduced in November, I started on 37. Now I'm 32. I say 95% of women are on 29 points a day.
