For 10 weeks I did a Low Fat/High Carb diet. I started running and worked my way up to about 3.5 miles 4-5 times a week. A stress fracture has caused me to stop running for now but when you see the stats below you will know why I was so frustrated.

During that 10 weeks I lost less than 2 pounds. So I switched to Low Carb in the beginning of August. Here are some weight loss stats from other runners on a Low Fat/High Carb diet

These numbers reflect runners that are trying to lose weight.
03.31.08 - 137
04.07.08 - 137.2
04.14.08 - 137
04.21.08 - 137.2
04.28.08 - 136.8
05.05.08 - 136.4
05.12.08 - 136.4
05.19.08 - 135.5
05.26.08 - 135.0
06.02.08 - 135.2
06.09.08 - 135.2
06.16.08 - 134.8
06.23.08 - 134.4
06.30.08 - 133.7
07.07.08 - 134.5
08.04.08 - 134.2.
08.11.08 - 133.4.
It took this person 5 months to lose 4 pounds. Is it any wonder people give up? I noticed that this is one of the more successful runners as far as weight loss went.

Here is another example, note the weekly mileage ran:
5/12/08 - 196.4 (-2.5) 27.2 miles
5/19/08 - 195.7 (-0.7) 16.0 miles
5/26/08 - 195.7 (no change) 27.4 miles
6/2/08 - 196.1 (+0.4) 24.2 miles
6/9/08 - 196.0 (-0.1) 26.1 miles
6/16/08 - 196.5 (+0.5) 24.2 miles
6/23/08 - 196.5 (no change) 30.3 miles
6/30/08 - 196.8 (+0.3) 30.1 miles
7/7/08 - 196.0 (-0.8) 27.4 miles
7/14/08 - 196.6 (+0.6) 28.5 miles
7/21/08 - 196.2 (-0.4) 34.5 miles
7/28/08 - 196.2 (no change) 28.5 miles
8/4/08 - ?????? (vacation) 21.3 miles (no long run)
8/11/08 - 196.5 (+0.3) 33.1 miles
See how many miles this guy runs a week? Basically no weight loss over a 3 month period.

Okay this is my last example. This person is only trying to lose those last couple of pounds:
5/26: 124.2 lbs (35 miles)
6/2: 124.2 lbs (65 miles)
6/9: 122.8 (69 miles) -1.6 lbs
6/16: 122.8 (61 miles)
6/23: 123.0 (87.1 miles)
6/30: 124.0 (67.7 miles) +1
7/7: 123.6 (45 miles) -0.4
7/14: 122.8 (55 miles) -0.8
7/21: 123.4 (58 miles) +0.6
7/28: ???? (35 miles)
8/4: 126 (21 miles)
If I ran 50-60 miles a week and I didn’t lose weight I’d be sunk so far into depression that I’d never get out. This person has gained weight!

Anyone that has ever tried to embark on a running program knows how hard it can be. I ran, I cried, I forced myself to continue and for what?! A measly 2 pound weight loss and a fractured leg!

Okay that's just my 2 cents. I'm goin' Low Carb!
