![]() Gnat was right, and had a very valid clarification of what I meant in my earlier post. sometimes this all just seems more confusing than it is or that I am making it that way. I have been really working out and lowered my intake-but I feel hungry and some days really weak after working out -I am having trouble staying awake and waking up in the morning and a before I increased my exercise I slept well and woke refreshed. ![]() I am trying to determine how to calculate my rdi. 8 hours a day max.), and hit your target RDI. So, keep breathing, don't oversleep (You burn half the calories asleep that you do awake. As FatSecret won't let us link, just Google search that sentence and you will find it. One that is very easy to use and provides numbers you can trust is the WebMD BMI Calculator. And as stated by Relz, DO NOT trust FatSecret's BMI calculator. So, if you find you're below your target for the day, EAT. Don't exceed a 1000 calorie (2 pound per week) deficit, or you risk going into "starvation mode", which will make your body slow its metabolism, thus greatly slowing or stopping your weight loss (by reducing that baseline number of calories needed for functioning). Your RDI is that number minus the 500 calories per weekly pound that you are wanting to lose. So, the BMI is the sum total of the calories you need on a day-to-day basis just to stay a living, breathing citizen of earth. In the former you're inactive, in the latter you're DEAD. Therefore, saying "I do not exercise" is not the same as saying "I burn no calories". Hell, THINKING takes calories (in fact, your brain is the biggest user of calories in your body). However, unless you dig ditches for a living or walk everywhere on your hands, you'll burn the vast, vast amount of your calories simply staying alive. How is this? Exercising is great, lemme preface this by saying that. I have done NO exercising, just the rest and sleep part. I've been doing this for only 3 days, and 2 of the days I'm down over 1000 calories. The FatSecret thing told me I should be eating 2000 calories to lose weight, and that if my net calories are down by 500 calories each day, I will lose one pound.
