If you want to lose 10 pounds, it's imperative that you have a plan. The chances of you being successful are very unlikely if you collect an odd batch of advice here and there and implement it sporadically. First, think of a realistic timeframe in which you want to lose 10 pounds. When you're doing this, keep in mind how much time you're willing to devote it, and how much you're willing to affect your daily routine: it's going to take more work to lose 10 pounds in 2 weeks than it is to lose 10 pounds in a month, for example.
Although healthy weight loss requires a balanced solution, when planning, pick which aspects of weight loss you'd like to focus on more: do you want to devote more time to exercise, and have more flexibility with your diet, or vice versa? When coming up with a weight loss plan, be realistic and think about how much time and effort you're willing to commit.
Making a weight loss plan is important because it gives you goals and something to stick to. Make your plan specific: don't say "I'm going to exercise this week," say "I'm going to exercise every day for 30 minutes when I get home from work." Try to come up with goals and expectations for yourself every day, so you can benefit from a regular sense of achievement.
The basic outline of your plan should incorporate both diet and exercise. A good way to start is to research a few healthy meals and plan to make them in your first week. This is more enjoyable than simply making a list of things you can't eat: you'll learn how to cook new things, and you'll have the satisfaction of preparing an enjoyable meal. The same goes for exercise: come up with some activities for the week. These don't have to be boring, work-type, exercise activities. Think of things like playing a sport, or taking a hike.
