Hi there. The way to lose weight is to burn off more calories than you consume. You could exercise for an Hour every day, but if you eat cakes, crisps, biscuits, processed foods or take aways, you won't lose any weight. Basically 'cut out the crap'.
Eat fresh fruit and veg, fruit juices (not fizzy drinks), water to clear the toxins out of the body (which will help with cellulite), fresh meat and poultry. Any exercise that makes you hot and sweaty is working the heart, which burns of the calories (fat).
Don't try to fool yourself with low fat, even if you eat these 3 times a day, your calorie intake may still be high. Skipping is fantastic, it gets the heart working quick. You can start at 3 mins with favourite upbeat track and build up from there, you will be surprised at how quick your body will react. Try to build up by 10 mins a week. So after 2 weeks you do 20mins a day, 3 weeks 30mins a day.
Trust me though, it will only work if you watch what you eat too. If you want to self indulge, either only have small amounts (ie 1-2 pieces of chocolate) or make sure you work for longer/harder to compensate.
