Can you create your own diet plans? Yes you can. Start by getting a calorie counter. Calorie counters are available in electronic as well as in book form. Depending on how much you weigh now, you can choose whether to create a diet plan for 1000 calories a day or 1200 calories a day. You will lose weight on this plan. Now it’s just a matter of portioning out your calories between breakfast, lunch, dinner and a couple of snacks. You may be surprised at how much you have to eat on this plan. You’ll find you’ll lose weight immediately, and that you continue to lose weight at the rate of 2 pounds or so a week.
