Reese Witherspoon’s weight loss of 20 pounds has been long overdue. Has a shirtless Jake Gyllenhaal inspired her to lose weight? Maybe he did, maybe he did not. It does not matter. What matters is that Reese Witherspoon’s weight loss has made her look and feel better.

Just a few months ago, Reese had packed 20 pounds onto her tiny frame, which made her feel really self-conscious, according to a friend. “When her clothes started getting too tight, she knew she had to do something about it. She doesn’t want to be seen as Jake’s frumpy girlfriend!”
