With regards to Slim Fast.... Personally I love it, particularly in this weather. The idea of having to prepare and eat a meal doesn't appear too much to me. I've been using SlimFast for approximately 12 months, on and off. I tend to use it now just as an easy meal now though.
I've lost in total 4st on it, originally a size 14/16 now I'm a size 10/12. I wasn't specifically using it to lose weight, more size really. However I do a lot of exercise, my average activity week:
Monday - Street Dance, Gym, Dance (ballroom and latin) practice
Tuesday - Gym, Dance lesson (Ballroom and Latin)
Wednesday - Dancing (B&L) class and practice
Thursday - Zumba, Gym, dance practice (B&L)
Friday - Dance practice
I also go jogging first thing in the morning, about 2 miles, takes approximately 30 minutes as I end up walking half of the distance.
I want to find some time to go swimming again, but that means trying to find a pool that opens before I go to work, which is a bit difficult where I live.
Of course due to all this exercise, the doctor said that when I do eventually get pregnant, I will need to carry on exercising for as long as I feel able to, because my body has got used to this level. Oh well....
