I wonder if I stick to the 800kcal/day fast for an additional week or two beyond the first two weeks, how much weight I'd lose. If I could lose an additional four pounds each week, it would make fasting those two extra weeks worthwhile! It would also bring me to a total of 18 lbs down over four weeks!
Then I'd only have to lose xx more to get to my initial goal. Afterwards, I could easily lose at least two pounds a week; I could do that in two months. by March 31.
Having extra weight off will allow me to run again, and doing the 5:2 Fast will allow me enough energy to pick up my cardio. So I should be able to start running again late January.
I will be doing yoga and riding my bike throughout January; slowly building strength and endurance over the month and adding in calisthenics. By the end of January or early February, I'll be ready to run again. And running will be so much easier with the extra 10+ pounds off.
I can do it!
