I work out as well, but the SB diet isn't really about losing weight so you can look better... like most diets. SB is about retraining your body to operate correctly so you can avoid the health problems that inflict many americans later in life: heart disease, diabetes, etc. It is still wrong to eat 'whatever', regardless of an incredible exercise plan. You need to cut all simple carbs or carbs with high a glycemic index (1. anything with 'white' flour like white breads, most cereals, cakes, cookies, etc. 2. all potatoes, period) and all 'added' sugars, meaning if it doesn't occur naturally in the fruit, veggie, etc. then don't put it in your body (like sugar, corn syrup, fructose, etc.). Replace bad carbs with good carbs (whole grain cereals, breads, crackers) and bad sugars with nothing or with a artificial sweetener.
A correct eating plan should always be balanced with exercise. With the SB and exercise, no joke, I am approaching the fitness, stamina and look I had 20 years ago when I was 21.
