FIRST OFF, I did this just to prove a point and see how much I could do. I lost alot of muscle going this fast, and iwas expecting it going into this diet. I recomend slower fat loss at about 1.5-2 lbs a week.
My Diet for the 1st 2 weeks were pretty normal and balanced.
50-75g fat, 150-200g carbs, 200-250 g Protein = 2100-2300 calories
My Maintainance was probably aroud 4000, so I had quite a big deficit.
During the first 2 weeks I was doing my 4.2 mile walk in the morning and a 2 hour intense workout at night. This was burning about 500-550 calories in the morning and my workout was burning another 1200 or so. I kept it very high intensity and kept my heart rate between 120-140 BPM the whole time.
The 2nd 2 weeks got a little more strict. I was then lowering my carbs and cycling them between low and "no" carb (<50g) and having a carbup day every week or so or whenever I felt weak. Even on my Low carb days, most of my carbs came Post Workout.
Low Carb: 65g fat, 125g carbs, 250g protein
No Carb: 90g fat, 50g carbs, 250g protein
Carb Up: 60g fat, 300g carbs, 150g protein
I was doing 2 miles of HIIT with 30 seconds on 30 seconds of, followed by a 2 mile walk. Took about 45-50 minutes.
For Supplements I took an EC stack with Lots of green teas.
Supplemented BCAA's during my run and workouts. Lots of it...
