Ex Smoker With A Few Pounds To Lose

My story is:

I recently quit smoking, meaning I also gained about 10lbs. I don't know the exact amount because I never weighed myself. I'm going off how my clothes fit. I'm in good physical shape and condition.

I don't have much time at all. I am 36 yrs old, have 4 kids, I'm a single mom and I run my own small business. So far the best I can do is go to the gym for an hour, three times a week.

I normally do 20-25 mins of cardio, 100 various crunches, and 20 mins of machines for the legs, arms, and back. My eating habits are good. No junk food, 1 or 2 diet sodas a day, coffee in the morning. no breakfast, small lunch, and healthy dinner with the kids each night. AND I take nutritional supplements.

I can only contribute the additional weight gain to an increase in calories at meal time. I am aware I was using cigarettes as an appetite suppressant. I have an appetite now and taste buds.

I know it seems vain to be concerned about a few extra pounds. I'm within the normal range for BMI, which is 25. I'm 5'10" and 175lbs. Not overweight but fleshy at the breast and hips. And of course this is where my clothes are too snug now.

This is really about economics for me. I can not afford a new wardrobe and it seems ridiculous to buy new sizes when I should be able to shed the weight.

The problem is: I can't shed the weight. I have been trying for 7 weeks now with no progress at all. I'm exercising, I watch what I put in my mouth, if I splurge on say ice cream I put in an extra little workout the next day.

Do I need a strict diet to follow? Do I need more workouts? Has anyone got a clue as to what I could do differently? I don't want a fad diet. I want long term results and weight maintanence.

It's almost fall and I have a whole closet full of professional clothes that don't quite fit anymore. HELP
