Jenna Jameson before and after: Star shows new 63-pound weight loss photos

Jenna Jameson is showing off dramatic results of her weight loss program on Instagram.

The mother of three and former adult film star, 44, shared new before and after photos on Instagram Sunday, saying she has lost 63 pounds since giving birth to daughter Batel Lu in April 2017

"I’m running like a well oiled machine," Jameson wrote in the caption,"Oddly enough I feel stronger, maybe because I’m not lugging around so much weight."

When she was at her high point of 187 pounds, Jameson says her ankles used to hurt and she suffered heart palpitations. "My ankles no longer hurt. I literally thought I needed to go to a podiatrist because it hurt to step down," she wrote. "I now don’t have heart palpitations."

The Sunday post came after Jameson posted a set of before and after photos on Thursday that went viral online.

"When I do make these before and after pictures it motivates me to continue!" Jameson wrote Thursday, making it clear she sees a "beautiful" body in the before photo "that gave life to 3 perfect children."

But the "after" results are powerful.

"Looking at the image on the right I’m in awe that THIS body birthed three humans!" Jameson added. "I’m rolling into this weekend charged and excited to stick to my program."

Jameson also posted a shot of her scale hitting 124.6 on Thursday, making the 63 pound weight loss.

Jameson listed her keto diet with fasting plan in a separate post last week.

Every morning I eat the exact same thing. 3 eggs with cheese and an avocado. Lunch is my biggest meal, I always eat arugula salad, grilled asparagus or zucchini with some kind of meat (usually a hamburger patty or grilled chicken) I then snack when ever I feel hungry (usually on almonds or macadamia nuts... sometime cottage cheese) that’s it! Then I begin my fast at 6 pm. I drink lots of water until I go to sleep at around 10 pm. I drink coffee at 8 am and I end my fast at 11 am. That’s it!
