One of the best ways to maintain a healthy weight is to ensure your metabolism is working properly. Metabolism varies massively person to person. Some are blessed with a mega fat-burning engine, others have to work a little harder. It's the luck of the draw.
That said, there are lots of ways of improving yours - a high one will help you shift unwanted pounds, or, if not lose fat, keep you body in balance. It's crucial to remember that more important than anything is a balanced diet.
It's said a lot, but it's true: fruit and veg, a dose of protein, and plenty of good fats are all essential. And exercise, of course. Here are a few other tips to help you stay your optimum weight...
1. Eat enough
If you're getting enough exercise, eating too few calories can mean that muscle is lost. Muscle helps the metabolism tick over - the more muscle you have, the more weight you'll lose, as muscles continue to burn fat long after you've worked out.
There's a simple equation bandied around by fitness instructors and nutritionists: 'weights for weightloss'. It's true - and eating enough protein, complex carbs and fruit and veg helps maintainance.
2. Drink green tea
Or any tea, really. One recent study found that participants who opted for green tea over fizzy drinks and soft beverages loaded with sweeteners lost two more pounds of belly fat than normal. Green tea contains catechins, a type of antioxidant that helps turn fat into energy.
3. Get in the gym
Continuing the exercise message, switching it up in the gym is important. Team sports for cardio, rowing, weights - they're all great. It's more fun that way too. Aerobic exercise is vital to keeping everything ticking over, weights are great to burn fat, and interval training - cycling, for example, quickly and then at a reduced pace for a period of time - together make for a solid foundation.
4. Some great foods that help
Many dietitians recommend eggs, broccoli, whole milk, olive oil, nuts, salmon and other lean proteins, and plenty of fruit and veg. It's all down to the nutrients they bring.
