Why is it so easy to gain weight, but so difficult to lose it and maintain the weight you lost?
As you lose body fat, hormones levels like leptin, drop. The signaling pathway that tells you you’re satisfied doesn’t work when leptin levels are too low. You don’t feel full, and you eat more than you need. A drop in leptin also slows your metabolism, so someone who goes from 150 to 130 pounds will have a slower metabolism than someone who consistently weighs 130 pounds.
Keep this in mind as your weight drops. Rather than tightening the noose in fear of regaining the weight, eat frequent small portions of nutrient dense food. By doing so you’ll help level out hormone levels and maintain your weight loss.
