327 Leptin Resistance [13 July 2015]

I have previously written several times about the role of insulin and insulin resistance in weight gain but there is another compound involved called leptin.

Leptin, sometimes called the “satiety hormone”, was discovered in 1994. It is secreted by fat cells and tells our brain that we have enough stored energy. It reduces our appetite and promotes the burning of fat for energy. Leptin resistance occurs when this message is blocked, resulting in food cravings, continued fat storage, and eventually obesity. Leptin resistance can also be a factor in female infertility.

Several factors contribute to leptin resistance:
• excess dietary sugar, especially fructose
• high insulin levels
• high triglyceride levels
• inflammation
• MSG (SHN #135)
• lack of sleep
• stress
• low calorie diets that are not ketogenic (your body thinks it’s starving)

So what can we do to reverse leptin resistance?
• greatly reduce simple carbs and processed foods
• eat adequate protein and healthful fats
• avoid between meal snacks to give your liver a rest
• exercise (but don’t overdo cardio)
• get at least 8 hours of restful sleep
• lower insulin levels (e.g. with a ketogenic diet)

Leptin resistance is recognized as a key risk factor for obesity (Zhou & Rui, 2013). Identifying the causes and taking steps to reverse it will make any weight loss program easier to follow and much more effective. The ketogenic diet we use in our Rosetown weight loss clinic doesn’t specifically address leptin resistance but does indirectly deal with the factors causing it, particularly insulin levels, triglycerides, inflammation and dietary sugar.
