I was astonished to see how much weight I had gained.
Are you trying to do something about the weight gain?
I will consider watching my calorie intake more carefully.
It's important to maintain a healthy weight. Monitoring your calorie intake sounds like a good idea, you can also make fitness goals to help.
Cute, but I doubt that willpower helps.
I know it is hard. Maybe you can talk to a nutritionist and they can help you eat better.
