Better Ideal Weight Body Calculations

I have to agree that I would feel & look better at 142lbs, which was one of the suggestions, but most importantly, I want to BE healthier not just look it, so I want to bring my BMI from 31.1 to 27.

I'm 5'5 too and my goal weight is 125, which would make my bmi 20.8. That is still in the Normal/Healthy range. I'm 145lbs right now, and I've lost 20 so far. I can see a massive differents in my stomach and legs, and face. Another 20 lbs and I'd feel amazing.

according to the bmi chart i should be between 101 - 132lbs. i was aiming for 116 (8 stone 4lbs) which was a weight i was happy with in my 20`s. however i may re evaluate as i get nearer and may stick with a weight about half a stone heavier due to my age and possibility of some excess skin which will weigh something. i dont want to be at my maximum as i know that my weight will fluctuate a bit. on the positive side i only have about 16 lbs to lose before i reach a healthy weight. 6 months ago i was morbidly obese. slim

The BMI is not the be all and end all of showing how much anyone should weigh.In fact it can be pretty deceptive.
Look at the NFL,most of these guys would be considered obese going by the BMI.
Many tall lightweight boxers would be considered underweight and undernourished by the BMI
Tall gangly marathon runners would also be considered underweight.
Would anyone call the top bodybuilders obese and overweight? The BMI would.
The best way to see how much you shouls weigh is simply to look in the mirror without your clothes on,and your mind will tell you if you need to lose weight or even gain a little.When you get to the point where you are happy with the way you look,then thats how much you should weigh.

Ideal weight (one of the "official" ways of doing it) = 45kg (for 150cm) and then add 0,85kg for each cm you have above the 150cm.
And that is the weight you should consider when calculating your protein needs. (there are exceptions of course, for example the "massbuilders", but for regular people, that will work).

Another one (taken of the book Nutrition pratical guide of Jacques Médart used at college)

Men: 50kg + [3/4 x (height in cm - 150)]
Women: equal the above x 0,93

But of course, these are just numbers, your ideal weight is the one you feel good with and can keep it, as long as you're with the right BMI.

I'm 5'7.5" and at my skinniest was 125 and people were telling me I was unhealthy looking...I can't imagine going down another 7 pounds from that and I have a pretty small frame.

I don't pay any attention to BMI. To me, Body Fat % is king. Right now, I am just under 30%. Using that, I would be well within normal at 315lbs. 306lbs would be ideal. With BMI, i should be no more than 228 lbs. i would have to lose at least 60lbs of muscle and bone to hit that!

i think numbers are not that important..

it depends on how big ur frame is..

but to me.. whats most important is that i feel good abt how i look.. if ur happy abt ur look then noone cares abt the actual numbers..

so.. dont get so stressed abt the number thing is what i suggest

Im 5'8 and I weigh 147. I went from a 3 to a 5 to a 7-8 to a 11 and now a 13!!!! Im quoting you because you said you were in a smaller size before but gained it back and it sounds like me. Girl we got to get back in those cute and small junior jeans.

Are you sure thats right? If you are referring to the 'Devine' Forumula it goes:

Men: Ideal Body Weight (in kilograms) = 50 + 2.3 kg per inch over 5 feet.
Women: Ideal Body Weight (in kilograms) = 45.5 + 2.3 kg per inch over 5 feet.

So my ideal weight would be 59.3kg

Seems a tad low for the average person.

This formular shouldnt be used:

"Problems with the Devine Formula for Ideal Body Weight
As descibed above, the Devine IBW formula suggests ideal body weight values that are too low in women generally and impossibly low in short women. Since the Devine formula is used by hundreds (perhaps thousands) of websites to suggest goals for weight loss, it is important to point out its limitations. The other formulas are rarely (if ever) seen on websites.

The Robinson and Miller formulas would perform poorly for tall men. The best compromise, in my opinion, is to use the Devine formula for Men, and use the Robinson formula for Women. In Men, the average suggested weight by the Devine formula, would give a BMI of 23.0. In Women, the average suggested weight by the Robinson formula, would give a BMI of 21.1.

However, these formulas have no method to compensate for Age and Current Weight. They are only based on Height. For people who are very overweight or obese, the Devine, Robinson and Miller formulas would suggest an ideal weight that is virtually impossible to achieve or maintain through dieting."

Ideal body weight formulas by Broca and Devine

I think i look best when i am arounD 11 stone (154lbs) Not fat at all and not too skinny. Eventually i wnat to get there but i will be happy enough to get down to 12st. This is measured purely on how my body looks and not in formula and BMI,....Im a simple creature really!!

I have a suggestion:
If you are really wanting to lose weight...ditch the scale and the "ideal" weight that you want to reach, at least for now.
Buy, or if you have one, a full length mirror. Stand in front of the mirror completely naked. If you see a body that has curves in all the wrong places...you know you are overweight. So get on a plan. Every couple of weeks (I do it maybe every two weeks), stand in front of the mirror naked. IF you like what you see, then continue doing what you are doing. If you don't, you either have to work harder, or change something.

Just MOHO

You could go by 5LBs for every inch over 5 feet and add 100 pounds or go by BMI. Either way is flawed. All I know is at 195 I can already see some of my rib so at 155 I would be skin and bones.
