| million dollar companies. Do you really think these businesses achieved success with a one-time, fix-all diet plan? No, they count on having most people return on a recurring basis; hence the term "yo-yo dieting". A lot of diet plans can be very limiting. You are require may consist of certain foods. Some plans are more exact and restrictive than others. Some diet companies even supply you with the actual meals. This means even more revenue(收入) for these businesses. A well-balanced diet consists of carbohydrates that are low in sugar (they're sometimes referred to as "good carbs"), proteins, and fats. (Yes, fats are important, too.) Fortunately for you, a well-balanced diet is all that is needed to safely and effectively lose or maintain weight, depending upon your goals. By educating yourself and having the willpower and commitment to make the proper food choices, you'll be well on your way toward achieving your weight-loss goals. After all, in order for a diet to be really successful, it cannot be just a diet. You must develop and conform to(遵守) a lifestyle that revolves around smart food decisions. This doesn't mean that you can never enjoy certain things that you crave(渴望), at least from time to time. We can all enjoy such things, but moderation is the key. A week's worth of smart choices deserves a meal out at your favorite restaurant. It also gives you something to look forward to and enjoy when you are saying "no" to those office donuts all week long. Don't get me wrong. It isn't always going to be easy. But rarely does anything worth having come easily. Liking what you see in the mirror, and being fit and healthy are definitely worth working hard for. Anyone can achieve such goals.
