In the past 2 weeks, I have purchased a treadmill and am walking 1hr/day. I am now allowed to eat 1/4c of vegtable or fruit with my 1/4c of protien food each day. I am still drinking 2 protien shakes a day and taking my vitamins. Even though I am allowed 1/4c of protien (or 2oz), I am finding I can only eat half of that at a meal. I have decided to split it between "lunch" and "dinner" into two mini-meals. I find this more satisfying and it helps me take in the extra nutrients. I have not experienced any negative impact on my progress either. My calorie intake averages 500/day or less.
For exercise, I walk 1 solid hour in the morning, then regular daily activities with occasional evening strolls as well. I average 8,000-12,000 steps per day, 5 flights of stairs, 3-4 miles, and 2,000-2500 calories burned. I have a Fitbit that keeps track for me.
