Upping Calories Closer to Goal Weight

its advised because the less body fat you have, the more muscle you will lose at higher amounts of caloric deficit. The more muscle you lose, the less calories your body burns (since muscle mass burns calories - not fat).

As far as when yo add calories, I used a bathroom scale with a body fat reading to track my muscle mass and make sure that by percentage of weight lost from muscle didn't go up - if I was it was starting to increase, I added calories and protein. Do you know what your percent body fat is now and what your goal is?

Question everything and go find the answers from a reputable source. There is no reason whatsoever to adjust the loss goal until it is time for maintenance. You will lose some muscle mass as you lose the fat. That is a given. Sorry. The trick is to do so in a manner that minimizes the lean mass loss. That is done with your nutrition plan and exercise. Your metabolism is going to slow down, but the majority of this is merely the reality that you weigh less and your body will use less energy as your fitness level improves. The law of depreciating returns does not play nice. There is also an adaptive component to the metabolism changes, but you have quite a bit of time before that will have a significant impact upon your goals so you can go read about that one.

If you are interested in learning about the so called starvation mode search for the Minnesota Study on that topic. It is very well regarded and will not be repeated anytime soon.

The BIA are not hugely accurate for many people, but they will show a trend over time. I can get mine to swing 5-10% and it is a well respected brand. They are quite sensitive to the water on board. Keep in mind all that data you entered (age, height, activity level) is being used with the impedance values to come up with a quasi estimate of your BF. Accurate tests do not require that kind of data because they simply measure the amount and report the value. Your age, height and activity levels make zero difference in reality since your BF is what it is.

People seem to be a bit confused how quickly one can build muscle. It is not nearly as fast as we would like. Many researchers suggest a male can add approximately 0.5lb/wk in the early stages of training with great nutrition. Those same studies suggest women can gain approximately 0.25lb/wk. These are just estimates based on test subjects, so sure you could build it a little faster, but I think it is helpful to have a basic understanding how hard one must work to build a small amount of muscle.

The loss goal is a personal choice. Learn to use MFP as a simple tracking tool and find what works for you with trial and error using the customized settings.

Keep at it, you are doing great.
