30 pounds in 4 months?? realistic?? help!

It is do-able but it is a bit much since you are not extremely over weight. I lost 10 pounds a month all last year but this year I average 4 on a good month.

I would really love to lose 30 pounds by the end of June (I'm 145 now, I'd like to be 115), and I'm on the MFP 2-pounds-a-week plan. This is realistic, right? Does anyone have any advice/tips on how to make this goal attainable? I'd so appreciate some help! Thank you so much!

Not sure how possible it is when you are only 145. For someone who is obese yes it is possible but for someone already in the healthy weight range it may not be impossible but gonna take a ****load of work. Why not do it slowly and change your lifestyle?

A pound of fat is about 3500 excess calories. To lose 7.5 pounds a month, you'd be losing about 1.9 pounds a week, so you'd have to have a 950 calorie deficit each day, meaning you'd eat 950 calories less than you burn (1.9 x 3500 = 6650 cals, 6650 cals / 7 days a week = 950 cals).

While that's easier to do when you're obese or more overweight, it's hard (not to mention sometimes unhealthy) to have a deficit that big when you get into a healthier weight range. I don't know how tall you are, but unless you're under 5'4", you're already within a healthy range, so rapid weight loss might not be as easy. Truthfully though, the way you lose matters more than a number on the scale. Eat right and treat your body well, and you'll get results.
