the brain.
Leptin resistance means your brain
doesn’t hear the leptin message and
thinks you’re still too lean. This

the down-regulation of your metabolism
(in part, via your thyroid).
Leptin resistance promotes insulin
resistance, in which cells are no longer
sensitive to insulin’s message to store.
Forcing nutrients into cells creates
damage and inflammation and leads to
chronically elevated blood sugar and
insulin levels.
Chronically elevated blood sugar and
insulin levels are contributing factors to
type 2 diabetes and a number of other
lifestyle-related diseases and conditions.

sugar and use fat for fuel, but only when
insulin levels aren’t elevated.
