Heidi Klum [1] did not get the nickname the body for nothing. After several pregnancies, we have seen her weight fluctuate with the best of them, but she always looked amazing.

So AOL [2] reported on how the body got her body back in catwalk shape:

When Heidi Klum, who reportedly gained 48 pounds while pregnant, hit the catwalk just seven weeks after delivering her son, Henry, she showed off a slender body that was the result of intense workouts with a trainer [3]. Heidi also followed a plan similar to the 3-Hour Diet, in which she ate small meals every three hours [4].
