Weight loss can give one a great measurable feeling, but remember that it isn't the weight which should matter most. What should matter most is the way your pants or shirts fit. Muscle weighs more than fat, so if you are converting fat into muscle, you may weigh more, but you will be trimmer and will be burning more calories.
As an overweight friend of mines says, "it ain't rocket science. Eat a balanced meal, reduce portions, and exercise." Breaking habits and creating new habits is the tough part, but once you get past about 45 days, the new habit becomes natural and you will not want to part from the new habit.
I have been on the SoWell plan, too, and haven't lost more than maybe two to three pounds since February, but I am now able to button my pants without having to suck in my stomach, and I often find myself hitching my belt tighter than I did before I started working out regularly. I still need to work greatly on my portion control and balanced meals, and could probably stand a bit more aerobic exercise, but lifting weights 3x a week has been a great start.
Step by step, you will get there (me looking in mirror), but you have to start somewhere. ;-)
