Not an eating disorder, but I used to eat very little and now I gain weight rapidly. What can I do?

How much do you want/need to lose? (your ticker confuses me with the negative numbers) How many calories per day are you eating now? What do you mean when you say you gain weight easily now? Like how many lbs in how many days eating how many calories?

Its hard to gain weight rapidly without trying. If this is a short term gain, most likely you are experiencing water retention. This appears like significant weight gain. (after sushi or a night of drinks, I can easily "seem" to have gained 5 lbs but a few days of regular meals and its all gone back to normal).

This is part of the cycle of making the lifestyle changes that you need to do to sustain a healthy weight for the rest of your life. You need to understand how your body reacts to certain foods and roll with it. Weight loss can not be determined day to day but should be based on a period of time (week, month, year etc). If you try to focus on the day to day, you will be disappointed and quickly.

If its a long term gain, you are eating more than you are burning.

Weight loss = eating at a calorie deficit.
Figure out what your daily calorie burn is (TDEE) and eat less than that over a period of time and you will lose weight.

FYI, I use a FitBit to figure out my TDEE and its worked well for me.

I want to get down to 115 which is where I was before my weight gain. I haven't been counting calories because I'm just starting out. I gained about 65 pounds in less than a year because I find time to eat breakfast, lunch, and dinner. I don't eat unhealthy but I can definitely eat healthier! Sorry about my ticker, I haven't been on here in forever!

If you've been gaining weight steadily for a year and you are working out with a trainer, then your weight gain is not the result of eating too few calories in the past. That is more than enough time to correct a dampened metabolism.

Most likely you are just eating more calories than you need. I would suggest logging your food as accurately and honestly as possible for a while to see where you can best make adjustments. Include everything you eat, including all beverages that are not calorie free.

If you haven't been logging your food, then you are likely eating more calories than you realize.

In addition, it probably isn't fair to compare yourself to your teenage weight since it is natural to gain some weight when you grow up and become a woman. For basic first steps, you should consider determining a healthy BMI based on your height, etc. and also your BMR/TDEE then come up with a reasonable calorie deficit that will help you get down to your BMI goal.
