Appetite hormones still elevated ONE year after diet ends

This study is getting a ton of press. Researchers in Australia put people on a diet, and came back one year later to see what happened. Their metabolism was still low, their leptin levels were also low, their ghrelin levels were high, and their peptide YY levels were low. Even if you don’t know what each of these things are, you should know that every single one of these changes predisposes a person to be hungrier. This might be why it’s really, really hard to keep weight off.
