Well, I've gained back about 50 pounds that I lost - so please don't go by my ticker... But, I did lose 50 pounds before and I've been overweight my whole life. I followed some advice from a few places and it really, really seemed to help alot. (having said that everyone is different but I've shared this with a few others and it seemed to help them too)
1. Dry brush before showering. This takes about 3 minutes. Rub in circular patterns. (including as far back as you can reach on your butt and hips and lightly on your breasts)
2. After shower, do not towel off. Instead, rub some kind of oil (I use Neutrogena Sesame Oil but whatever) all over. This holds the moisture into your body. Don't towel off afterwards. You will dry very quickly because the oil makes the water suck into your body.
3. Water, water, water, water, water, water.
4. If you can, get a medicine ball (not very heavy - like 2 - 4 kg) and do some exercises with it. It is strength training only really fun. This seems to help your muscles which makes your skin look much nicer.
Anyway - I know there are loads of other tips but these are a few! Good luck on your weight loss!
