Sounds to me from reading your posts here that you dont know how many calories you should be consuming each day, and no comprehension of what good food and proper exercise is... at the risk of sounding mean, which is not my intention... you should do more research and less diarying and listening to people tell you that you are doing well when your starving yourself, eating the wrong foods and rationalizing these poor nutritional decisions. Your legs give out on you during your taebow because your not eating enough... starvation diets have not, do not and never will work for sustained fat loss and in fact will add in fat gain. Hence the 8lbs of fat you put on over the December period. Do you realize that there are 3500 calories in a lb of body fat so x that by 8lb gain and you ate almost 28,000, yes twenty eight THOUSAND calories more than you burned up in energy over this period. Sorry for the honesty but you should read more about and become educated in the the science of nutrition and exercise and get educated from people that know how to do this properly and sustainably. It should be a life long quest and not a week to week day to day proposition.
One last thing... don't get mad, angry or depressed with this post GET DETERMINED and EDUCATED in making this a LIFE LONG ENDEAVOUR in becomming fit and healthy for life... for you will learn and findout first hand that if you do this properly then you will be able to eat more food than you ever have and still gain muscle and loss fat.
Throw the SCALES away, measure yourself, and find out your Lean Body Weight, so that you can calculate how many calories you need to consume each day to be energetic fit and healthy.
I can post here a mathimatical formula for you that requires only that you take 4 measurments and perform an 11 step mathimatical (all explained) equation to get an accurate bodyfat measurement, so that you know how much muscle mass you have and then plan accordingly for your energy output for the day. This is the only real and sustainable way to lose fat and keep it off.
If you want to put in the work then let me know and I will post the formula for you, and also try and get posted it as one of those sticky things. This is not a sales pitch, it will cost you nothing there are no websites to go to, nothing to purchase just some free and relevant information from a trainer with 30 years experience in the fat loss industry.
