Ways to lose weight

Since I wanted to lose weight,I read some sites that are related in losing weight.I read in one of the site that if a person want to lose weight,there are many ways to do it.It stated there that exercising and dieting are good.I read that a person should change lifestyle and diet,drink lots of water,exercise regularly,have a 7-10 hours of sleep everyday or taking weight loss supplements that are effective and safe.Also,you have to consult your doctor if the supplement that you want to take is safe and effective for you to use.It's better to be safe than to be sorry later,right.
