Calories burned, is it all voodoo? HR monitor, Elliptical, and online calculators differ by up to 50%. Is one more accurate? I'm 250 lbs, FFM 180 lbs

Calories burned, is it all voodoo? HR monitor, Elliptical, and online calculators differ by up to 50%. Is one more accurate? I'm 250 lbs, FFM 180 lbs

Beware the machines: While exercise machines attempt to alert users of calories burned and wattage acheived, the reality is unless in a sport medicine clinic, you probably are not getting accurate results. I am a strong proponent of regular exercise, and then increasing intensity and duration as tolerated. However, it is what you put in your body that is going to make the biggest difference to your fitness goals. ...Read more

What should my calorie intake be to lose weight? My first Doctor said 1200 but calculators say 2100. 310lbs 5'3" female 22 years old. Thank you!

What should my calorie intake be to lose weight? My first Doctor said 1200 but calculators say 2100. 310lbs 5'3" female 22 years old. Thank you!

It depends: Do you want to sustain your weight or lose weight? It may be best to consider weight loss since a 5'3" frame will have diffculty sustaining that weight over time without joint damage. Your calorie recommendations are extremes on a spectrum. I would suggest starting at 2500 carefullly counted for 2 months are drop by 100 every 2 months until you get to 1500. Return to 1800 when at goal weight. ...Read more

I want to increase my muscle mass. I understand I must increase my calorie intake, but by how much? Is there a calculator/ formula? I'm 5'6 weigh 158.

Wrong approach: Increase your protein intake, not your calorie intake. Increasing calories just makes your fatter, not stronger. The key is strength and resistence training on a regular basis. If you do not do that, you will not gain muscle mass. ...Read more

Is there a safer alternative for TPN treatment. My wife is suffering from acute pancreatitis.

Is there a safer alternative for TPN treatment. My wife is suffering from acute pancreatitis.

Discuss with her doc: Treatment for acute pancreatitis is primarily resting the pancreas. It depends on the severity of the pancreatitis, but most patients are advised not to eat until symptoms are subsiding and pancreatic enzymes are decreasing. If she needs to not eat for a long period of time, TPN may be the best way to keep her strength up. Each patient is different with pancreatitis and nutritional needs. ...Read more

If u don't want that, u can specify so in the advanced directive. If u don't want a feeding tube, u can specify that also.

How does TPN compare to a glucose IV for nutrition?

How does TPN compare to a glucose IV for nutrition?

Much better: Glucose IV is really not nutrition. Nutrition includes balanced protein, carbohydrate, lipid, electrolytes and other ingredients, all included in TPN and often personalized. We use glucose ivs short-term to avoid hypoglycemia that may happen from the body spending the available carbohydrates for energy. That being said, enteral feeding is always better (what goes in the stomach and bowels). ...Read more

Who needs to have total parenteral nutrition (tpn)?

Bowel rest: If swallowing is an issue, we can give food via peg tube thru skin directly into stomach. But some patients need bowel rest so we give total parenteral nutrition (TPN) through veins so nothing is in stomach/intestine. These are major veins, not tiny ones on back of hand, usually via picc (peripherally inserted central catheter) line since it's expected that you'll need TPN for a long time. ...Read more
