What is now your new goal for your weight loss? The reason I ask is you have both lowered your calories consumed, and increased your exersize, I know you want a cushion, but your weight will go up and down by a few pounds over time. As you know, this is normal. Furthermore, you do have the capability and the discipline to reign it in any time you choose to do so. As you have proven, you do know how to lose weight. Remember that there is not just one value but a range of BMI values for a physically fit person. Are you taking into consideration what you have gained in muscle mass? IMO this can make the difference of a couple pounds by itself. IMHO once you reach your weight goal, your feeling the necessity of providing yourself a cushion basically makes your target weight rather arbitrary anyways. Please do not let paranoia get the best of you. I am not trying to come across like I know better than you. It is just that these are the things that I frequently wonder about.

PS I need to take my own advice.

All of this is FWIW
