Steroids do survive digestion, that's why you can take oral contraceptives, Vitamin D, or prednisone by mouth. They are all steroid-based. Protein hormones (insulin, growth hormone), on the other hand, cannot survive digestion and that's why they're given as injections or oral/nasal sprays. The primary scare with injecting…

Protein restriction was shown in a few studies to slow down the progression of glomerular disease and/or proteinuria. If you have these problems, a nephrologist would probably advise you to a protein restriction of 0.8 - 1.0 gms per kg body weight per day.

The incidence of osteoarthritis of the knee is similar in non runners and runners. What's bad is running on a a damaged knee. If you strengthen the muscles supporting the knee joint and adopt a sane training regimen, your knees should remain relatively injury free. In some cases, your knees may become stronger with…

Endomondo? If you record a new workout using the sport Step Counter, you can also save the number of steps you have taken. They also have stats such as number of trips around the world, to the moon and how many burgers you have burned.

Smartphone with ANT+ chip. Then get an ANT+ HRM chest strap from Garmin, Timex, Suunto, etc. You can also use other ANT+ accessories such as a foot pod, bike cadence sensor, weighing scale, etc. I think a lot of Sony-Ericsson Phones (Active, Ray, Xperia Pro Mini, etc) and a few from HTC have ANT+ chips. The SE Active is…

Exercise does help people with asthma. Exercise stretches your lungs and airways and reduces the work of breathing by reducing airway resistance. Aerobic capacity is also better, so during asthma attacks you won't feel as tired or as short of breath because your lungs and tissues can extract oxygen much better than if you…

Absorption of electrolyte drinks is quite fast once it reaches the small intestine, although I don't have the numbers for you. The glucose included in this type of drinks are not actually for extra calories nor for the taste (well at least originally), but they help transport the sodium from the gut to the bloodstream.…

It's possible you are losing more electrolytes than usual during your lifting days causing you to cramp later when you run. Try replenishing your electrolytes before you run.

Excess dietary salt (or specifically sodium) is excreted by the kidneys. But there is a limit, and the excess salt not excreted by the kidneys stays in your bloodstream. Since sodium and water are intimately linked, excess sodium also causes water retention. The consequence of water retention is typically elevated blood…

See second and third paragraph.

A bad carbohydrate is basically a simple carbohydrate. They are simple because their molecular structure is simple and thus easy to digest. For example, table sugar is composed of 2 molecules of glucose only. If a carbohydrate is easy to digest, then all the calories are released immediately to your bloodstream, causing…

Glycogen (our main storage form for glucose) binds water at a 1 to 2 ratio. So if you burn 1000 kcals (equivalent to 250 gms of glucose/glycogen), you release 500 ml of water. Burning fat can also produce water, but at a smaller amount (100 gms of fat produce 100 ml of water). You also tend to drink more water than…

Food rich in fiber (whole grains, whole fruit, legumes, vegetables). Fat restriction is not as important, but cut down on food rich in cholesterol and trans-fat (hydrogenated fat, margarine, cookies, cakes, crackers). You may increase monounsaturated fat intake (olive oi, canola oil, nuts).

It's doubtful that 3-4 liters of day can overwhelm your kidneys. Normal kidneys can filter upto 150 liters per day, although 99% of that is reabsorbed back to the bloodstream. The main danger of drinking too much water is hyponatremia (or low serum sodium) which is the primary problem of water intoxication. This condition…

Hypokalemia (or low blood potassium) is rare in a healthy person eating a balanced diet. That's why potassium is not required to have an RDA. So unless you are on some kind of water pill, you don't need to watch your patassium intake. Just follow standard advise -- eat a balanced diet, replace electrolytes as necessary…

In order to support your BMR + daily activities, you will need 2110 calories per day. If you eat only 1610 kcals, you will still need 500 kcals to survive. It will come from the burning of your stored fats (and muscles). Since there is approximately 4000 kcals per pound of fat, you need to burn 500-600 kcals worth of fat…

You mentioned autoimmune disease. Better ask your doctor what specific autoimmune disease you have. Autoimmune diseases are usually multisystemic, and may affect your kidneys (causing hypertension and water retention) or your cardiovascular system (atherosclerosis which can also cause hypertension). There are many kinds of…
