You probably know that hundreds of different fad diets, weight-loss programs and outright scams promise quick and easy weight loss. But the foundation of every successful weight-loss program still remains a healthy diet combined with exercise. You must make permanent changes in your lifestyle and health habits to lose significant weight and keep it off.

How do you make those permanent changes? Follow these six strategies.

1. Make a commitment

Permanent weight loss takes time and effort. It requires focus and a lifelong commitment. Make sure that you're ready to make permanent changes and that you do so for the right reasons.
No one else can make you lose weight. In fact, external pressure — often from people closest to you — may make matters worse. You must undertake diet and exercise changes to please yourself.

As you're planning new weight-related lifestyle changes, try to resolve any other problems in your life. It takes a lot of mental and physical energy to change your habits. So make sure you aren't distracted by other major life issues, such as marital or financial problems. Timing is key to success. Ask yourself if you're ready to take on the challenges of serious weight loss.

2. Get emotional support

Only you can help yourself lose weight by taking responsibility for your own behavior. But that doesn't mean that you have to do everything alone. Seek support when needed from your partner, family and friends.
Pick people who you know want only the best for you and who will encourage you. Ideally, find people who will listen to your concerns and feelings, spend time exercising with you, and share the priority you've placed on developing a healthier lifestyle.

3. Set a realistic goal

When you're considering what to expect from your new eating and exercise plan, be realistic. Healthy weight loss occurs slowly and steadily. Aim to lose 1 to 2 pounds a week. To do this, you need to burn 500 to 1,000 calories more than you consume each day through a low-calorie diet and regular exercise. Losing weight more rapidly means losing water weight or muscle tissue, rather than fat.

Make your goals "process goals," such as exercising regularly, rather than "outcome goals," such as losing 50 pounds. Changing your process — your habits — is the key to weight loss. Make sure that your process goals are realistic, specific and measurable, for example, you'll walk for 30 minutes a day, five days a week.

4. Enjoy healthier foods

Adopting a new eating style that promotes weight loss must include lowering your total calorie intake. But decreasing calories need not mean giving up taste, satisfaction or even ease of meal preparation. One way you can lower your calorie intake is by eating more plant-based foods — fruits, vegetables and whole grains. Strive for variety to help you achieve your goals without giving up taste or nutrition. Cutting back on calories is easier if you focus on limiting fat.
