Swimming is a great way for you to lose excess weight because it burns off many calories. Go to your local gym and sign up for a gym class even if you have a pool at home. Feeling self conscious in a bathing suit might be the boost you need to lose more weight.
Get your calcium from the correct sources. Studies show that people who get their daily amount of calcium from food sources, rather than supplements, are likely to have much less body fat than someone who doesn't. If you aren't meeting your daily requirements at all, you are even more at risk.
Avoid drinking coffee when you're trying to lose weight. Caffeine can make you retain water, have high blood pressure, and can irritate the lining of the stomach in some people. If you feel the need for a hot drink, try heating up a glass of milk or having a pot of tea.
