To make my question more clear, I'll give you an example that applies to me. I am 5'1 and I weigh 103 pounds. According to bmr calculators online, I need to consume 1300 calories per day to maintain my weight if I literally stayed in bed all day and had 0 physical activity. After adding in my daily physical activity, I figured out that I need to be eating around 1700 calories per day to maintain my current weight. I would like to weigh 98 pounds so I figured if I eat 1300 calories per day I will lose a little more than 1/2 pound per week.
What I don't understand is the weight loss plateau that pretty much everyone hits. If I hit my plateau after losing 3 pounds, what should I do? Does this mean I need to create a larger calorie deficit? Lets say I reduce my calorie intake by 100 to lose those last 3 pounds and then hit another plateau when I get to 98 pounds. Does this mean I would have to consume 1200 calories per day for the rest of my life in order to maintain 97 pounds? What I don't understand is according to the calculators online, losing 6 pounds would only decrease my daily caloric needs by about 30 calories. To maintain 97 pounds, I should be consuming around 1670 calories. Once I stop my diet, how can I ever get myself to eat the amount I SHOULD be able to eat to maintain my new weight and not gain. This whole process of weight loss is a lot more complicated than I though.
