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

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

You likely conceived near the end of march or at the beginning of april. It is generally two weeks after the start of your new cycle. ...Read more
