COVID Weight Gain Is Totally Normal: Try These 9 Nutritionist-Approved Tips for Dealing With It
Gain pounds if you're underweight. if you started at a normal weight. if you're overweight. And if you're obese. When you're pregnant with one baby, get about extra. Your healthy weight gain during pregnancy may depend on the weight you were before you got pregnant. There are no official guidelines in the UK but the American College of Obstetricians and Gynecologists say that: women who are underweight (BMI under ) are recommended to put on between lbs (kg) women in the normal weight range.
Some of us overdo things with shakes and powders, some with 2 pound steaks. Like all the diet factors in stone and bone disease, protein intake is complex. Certainly, we all need protein in our diet but how much? Experts debate the best what causes the smell behind your ears, and patients wonder what to do. I chose it, as opposed to others more brilliant, because it looks modern Ч I have seen something like it on my own dining room table.
In preparing this article I have made considerable use of the analyses performed by professor Tanis Fenton. She graciously read and edited the article up to the details of renal physiology, and the work much benefitted from her expertise which I gratefully acknowledge here. All errors are entirely mine, however, should you find any. A subsequent WHO meta analysis of mostly the same underlying data supplemented by more recent studies comes to much the same conclusions, but in perhaps a more nuanced manner.
A more recent analytical critique of the whole matter is not remarkably far off in estimates for adults, though pregnancy and childhood seem controversial. This summary graph from the critique gives a sense of how the protein requirements are set. The median requirement is where about half of all studied subjects were in neutral nitrogen balance Ч their body protein mass would be stable, a very important matter.
The safe population intake is set higher. The safe individual value is high enough enough that Although the safe individual intake is correct, within a population individual requirements vary, so the recommended level needs to be increased so that That number from the WHO meta-analysis, the safe population intake, is about 1. Given the safe individual intake is 0. This means that in helping patients choose a protein intake for stone prevention we work in that range 0.
This measure what does infectious disease mean applicable to healthy people who are neither gaining or losing protein mass. Like sugar, protein loads raise urine calciumand urine calcium is a major risk factor for stone formation. Low protein intake may reduce urine calcium but is bad for overall health. Whether or not high protein intake raise urine calcium at the expense of bone integrity is fiercely debated right now.
Low protein intake is not good for bone. I could just tell remind you that the high and low markers for normal people Ч not otherwise compelled to high or low protein diets Ч are between 0. I believe understanding is the key to long term treatment and encourage what are cream filled donuts called to read about protein.
Physicians already know everything I write about, but many way enjoy a ride through a familiar and charming countryside. For several generations we have known that the sulfur containing amino acids cystine and methionine produce an acid load and that rising diet protein acid loads correlate with increased urine calcium excretion.
Giving acid loads experimentally increases urine calcium excretion. Some believe acid loads promote bone fractures by mobilizing bone mineral stores and that alkali treatments prevent this form of bone loss. Others believe that the protein increases urine calcium by increasing intestinal calcium absorption and does not adversely affect bone. The acid loads were varied by variation of diet protein, by giving alkali such as potassium citrate and by giving acid loads like ammonium chloride Ч a purely experimental strategy.
No matter how acid load was varied urine calcium varied linearly. The points on this graph are from Table 2 of her paper. I have redrawn her figure to suit my taste. My data set is available for others. The negative changes in net acid load are from alkali loading such as potassium citrate. Her approach emphasizes the quality of the human trials.
Another review more emphasizes the underlying technical problems of assessing net acid base balance. Despite the differing formalisms and even scientific instincts of the investigators who reviewed the topic the one a group of skilled analysts, the other a group of expert acid base physiologists the overall result is amazingly uniform.
For example at about net acid excretion, there would be about 50 mg less urine calcium and at about mEq of extra acid about mg more urine calcium in both studies alike. Whereas the Fenton points easily fit a linear regression, the larger range of the Lemann review shows the response is not linear but has a curving character. If you look closely at the Fenton points there is indeed a slight sag around 0 meaning that perhaps a curving regression might have a higher multiple R 2.
The point of showing all this is obvious: However you review the papers, acid loads increase and alkali loads reduce urine calcium, meaning this is a vigorous phenomenon, not some houseplant that cannot stand up to the weather. It has been found in many laboratories over many decades, in humans Ч shown in these two figures Ч and animals alike. By this one must mean does a change in diet protein raise urine calcium more than would a corresponding increase in net acid load from some other source.
Alternatively, it could mean what happens if one gives a protein load with enough alkali to offset the acid from the protein. Four studies appear to fit the needs for data in that they are trials of protein loading in a rather pure form, using foods and with considerable care for total nutrition.
Of these, one used alkali to offset the protein acid load. The points taken from these additional reports are here. The Fenton data are in a faded blue, for visual contrast.
The protein load studies are in red. In the one special trial it is obvious that the K Citrate diamond lowered the change in NAE without affecting the change in urine calcium. So it is possible to dissociate a protein effect from its acid base effect within the controlled environment of a trial.
Given the modest quantitative changes in NAE it is possible that natural variability of urine calcium excretion might have permitted apparent stability despite the lack of a change in NAE in one point and a significant increase of NAE in the other, but the statistical testing is based on the observed variability and gave a low probability from chance alone. Essentially the trial of diamonds and pentagons tells us that protein itself has a renal effect on calcium handling.
I am not so unwise Ч being an expert in stone disease not bone disease Ч to enter into this debate on my own. All I can do is present recent reviews by the real experts who do not seem to have convinced one another. Fenton has performed what appears to be a rigorous screening of available balance studies concerning the effects of acid loads and protein intake. She culled out eight studies that met the criteria used by the Institute of Medicine in their assessment of dietary requirements for calcium and vitamin D.
Her dataset is not presently available to me but I have replotted her summary data in a manner I find ideal for this site. The abbreviated names refer to her Table 2 in the reference.
The data I extracted and plotted are here. Change in calcium balance does not vary importantly with change in protein intake upper left panel nor at all with change in net acid excretion NAE from the protein amounts and types upper right panel.
There is perhaps a slight inverse relationship between change in balance and change in urine calcium lower left panel and, as in less curated studies shown above, a marked direct relationship between urine calcium and NAE lower right panel. The only way balance upper right panel can be indifferent to change in NAE and yet inverse on urine calcium which is itself dependent on NAE is that changes of intestinal calcium absorption make up the difference from calcium lost in the what does smt stand for. One presumes this but proof may be beyond the resolution of calcium absorption measurements.
At least one important research group performed what appeared to be a fine balance study in which potassium citrate was given to neutralize diet acid load and calcium balance was measured by an expert in such work. I have plotted the new study points in red over the Fenton analysis in blue and have removed linear smoothers for clarity.
In a sense all of the studies agree about urine calcium. A change in NAE gives rise to a reasonably stable and predictable change in urine calcium here as in the much larger data sets I already reviewed. For balance right panelthe placebo and 60 mEq potassium citrate points are not out of range of the other studies Fenton considered although with these two points Ч and of course their many more internal measurements Ч there might be a slight inverse relationship between NAE and balance.
The single 90 mEq point would make a more powerful negative regression, as is obvious. But if this study were indeed part of the elect minority it might change opinions. Perhaps I should say something, however, and it is this. Potassium citrate does lower urine calcium just as acid loads raise how to build floating kitchen shelves, and so far as I can tell the agent will how to wash chilly pad towel worsen bone mineral balances.
So in giving it I have no reservations about bone just as I cannot have definitive hopes for better bones as a result, at least right now. In a prior article I showed the urine calcium lowering effects of potassium citrate were independent of the effects of diet sodium. But those data, and trial data like it are observations.
Suppose you give people an acid load so their urine calcium goes up as a result of what you did and also varied sodium intake Ч a direct experiment, not observations.
I did thatand although others also may have done the same, my experiment was a good one and I like it. Four people were studied during three control days Ч points to the left on the graph. They had normal urine calcium excretions lower panelnormal serum PTH levels middle panel and normal serum total calcium upper panel filled circles and ionized calcium open circles.
That is what one expects from normal people. I gave them ammonium chloride which is an acid load, and as you might expect by now their urine calcium should go up. But, I also lowered their sodium intake to 40 Ч 80 mEq daily average about mg and Ч take a look Ч urine calcium did not change. Their blood became distinctly acidic Ч you will have to look at the paper.
The calcium ion rose and the total calcium fell because the acidity tends to liberate calcium ion from binding to blood proteins and from phosphate complexes. I then raised the diet sodium to about mEq mg and there was the urine calcium increase. Serum PTH went up, too, perhaps because the kidneys were losing calcium. All of this experimental data emphasize the importance of diet sodium. Given our protein intake imposes a tonic acid load, low sodium diet should presumably act as it did here and lower the calcium losses acid loading may well create.
In a well performed study of bone mineral balance in menopausal womenwhat day is despicable me 2 coming out was the combination of reduced sodium intake and increased calcium intake that brought bone mineral balance into a positive range. Given this, I would add to my prior statement that low sodium diet is itself safe for otherwise normal people and is likely to benefit bone health, or at least do no harm to bones.
Physicians and scientists know this material and can read it fluently. If you are not one of those, you can read what is coming and find is very interesting. I avoid jargon, and explain things reasonably well. However response to acid or alkali loads is a fundamental property of kidneys, crucial for life, deeply embedded in the way they function and elaborated and refined by millions of years of evolutionary biology.
It is, therefore, elegant in its way how to call mexico from toronto hard to grasp.
Many investigators have shown that chronic acid administration raises urine calcium by reducing tubule calcium reabsorption.

If you are concerned about your weight, talk to your GP, midwife or health care provider. Our Get Healthy in Pregnancy health coaches can help keep you on track with your pregnancy weight gain goals.
These results are based on the Institute of Medicine recommendations. Please note that recommended weight gain ranges are a guide and provide suggested limits rather than specific goals. The Institute of Medicine recommendations for pregnancy weight gain only covers up until 40 weeks of pregnancy. You may continue tracking your weight gain on the calculator, but please consult your pregnancy carer for advice past your estimated due date. If you are 18 or over, a healthy weight gain range can be calculated based on your pre-pregnancy body mass index BMI.
By staying within this range throughout your pregnancy you and your baby are more likely to be healthy. You will also be less likely to experience pregnancy and birth complications. Body Mass Index or BMI is a frequently used method of measuring weight ranges in adults aged 18 years and over who are underweight, at a healthy weight, over a healthy weight overweight or way above a healthy weight obesity.
It is calculated by dividing weight kg by height m squared. Gaining too much weight during pregnancy can increase your risk of developing complications such as gestational diabetes, high blood pressure, having a bigger baby and complications during birth. It also means there is a greater chance of your baby becoming obese during childhood and adulthood.
If you are concerned about your weight, talk to your GP, health professional or enrol in the Get Healthy in Pregnancy Program to receive advice from a health coach. Gaining too little weight during pregnancy can increase your risk of going into labour too early, having a baby that is smaller than expected and having problems breastfeeding your baby.
It can also increase the risk of obesity and diabetes in your child. The calculator is based on the Institute of Medicine recommendations for weight gain in pregnancy. Your first ultrasound gives the best indication of your due date. If your date changes, you can re-enter your expected due date in the calculator as many times as you like.
This may change your healthy pregnancy weight gain range. It doesn't have to be exact. Try and estimate your pre-pregnancy weight as best you can or ask your GP or health professional what they think it was. If you are below 14 weeks you should only have put on 2 kg, so this is a good place to start. If you are under 18 it is recommended to see your GP or health professional about your healthy weight gain during pregnancy, and get regular dietary advice on what foods are best for you from a dietitian.
The guidelines used in this calculator are targeted towards adults 18 and over. This is because your body composition and size is different to adults, and the adult measure of body mass BMI does not include under 18 year olds.
