The Protein and DHA Fix
Losing fat decreases leptin release, which makes you want to gnaw your arm off. Here's how to fight that to make fat loss easier.
Your body hasn't kept up with the times. As remarkable as it is, it's like inheriting a car with a cassette player instead of device ports. You can't charge your phone, but hey, you can bang your head to a Quiet Riot tape.
The human body is kinda like that. It still thinks you may starve to death at any moment. To help you survive, this highly efficient energy storage machine is equipped with all the latest technology of 250,000 years ago.
One of those tricky bits of tech is called leptin. You know it as the satiety/fullness hormone that helps regulate hunger, energy balance, and body weight. You may not know that it's released from your own energy reserves: fat cells. And that's where it gets tricky.
Still worried about starvation, your body fights against your efforts to lose fat. "Hey, I was saving that!" it says. "Oh, you want to see your abs? Idiot! You'll die in the winter!" To work against your silly physique goals, the body starts manipulating leptin.
Here's what happens and how we can negotiate with your stubborn ol' body.
The Leptin Paradox
Like all hormones, leptin's character alignment is "true neutral." It's neither good nor bad; it just seeks balance. Low leptin levels trigger hunger and reduce energy expenditure: your body tells you to eat something and slows your metabolism. The problem? Getting ripped involves eating less and burning more calories.
When you lose fat, you have fewer (or smaller) fat cells, which reduces leptin production. Your body is fighting against losing that precious stored-away energy in your love handles.
How bad is this reduction of the "I'm not hungry" hormone? Well, to test the extreme, researchers took some already lean men (9% body fat) and put them into a caloric deficit of 60%. Half the men dropped a ton of calories to get into that big deficit and half used a combo of lower calories and increased cardio to hit that same deficit.
Both groups lost a bit over 4 pounds in four days, and both groups saw a 52 and 56% decrease in leptin production. (The cardio + diet group had the worst drop.) That means they were hungry, suffering, and probably annoying to everyone around them.
Too Much Leptin Sucks Too
So, if we produce a lot of leptin, it'll be easier to get shredded because we can eat exactly what we need without hunger or cravings, right? Well, not so fast.
If you really elevate your leptin levels, you might develop leptin resistance. In short, that means you're producing a whole lot of leptin but your body isn't responding to it anymore. It's like if your spouse is constantly nagging so you stop listening to anything they say. The signaling pathway to your brain is disrupted, leading (again) to constant hunger and reduced energy expenditure.
Leptin resistance can be caused by chronic overeating ("forever bulking, bro"), inflammation, high triglyceride levels, stress, and bad sleep.
Fighting Back
Overweight people trying to get healthy and lifters chasing abs face the same problem: the fat loss drops your leptin levels and makes you crazy-hungry. For both groups, training improves leptin sensitivity. So does a slow and steady approach to fat loss vs. an extreme diet.
But knowing how leptin balance works, we can tip the scales in our favor with a couple of tactics:
1. Eat More Protein
Higher protein diets increase leptin production – the amino acids influence leptin gene expression. Some studies show that diets higher in protein lead to greater leptin secretion from adipose tissue compared to diets high in carbs or fats. Protein-rich diets also improve leptin sensitivity via improved insulin sensitivity.
Acutely, a high-protein meal temporarily increases postprandial (after-meal) leptin levels. So, you get full and stay that way longer.
Longer term, a higher-protein diet keeps the fat loss coming if needed and makes maintenance easier. This is due to improved leptin sensitivity. Even if your body isn't producing enough leptin, the leptin it does produce is more effective at regulating appetite and energy expenditure.
How much protein? It's hard to go wrong with the old "eat a gram per pound of body weight" rule. Maybe shoot for a bit more if you're already lean and trying to get ripped. If you're very overweight, eat about a gram per pound of ideal body weight.
An easy way to do this is to consume 2 to 4 scoops of MD Protein (Buy at Amazon) daily. That'll provide you with 44 to 88 grams of leptin-regulating protein. The rest is easy to get from other foods.
2. Boost Omega-3 Intake
Omega-3 fatty acids, particularly DHA, positively affect leptin levels and sensitivity in several ways. Remember, chronic inflammation impairs leptin signaling in the hypothalamus, the part of the brain that regulates hunger and energy balance. DHA tamps down this inflammation and improves leptin sensitivity.
Also, high triglyceride levels inhibit leptin transport across the blood-brain barrier. Omega-3s reduce triglyceride levels, which enhances leptin transport and improves its signaling.
DHA especially influences the expression of genes involved in leptin production. It helps you regulate the amount of leptin produced by stored fat, leading to more appropriate leptin signaling based on body fat levels.
Most omega-3 fish oil supplements contain primary EPA, not DHA. So if you supplement, use Flameout DHA-Rich Fish Oil (Buy at Amazon). It contains 2000 mg of leptin-balancing DHA.
The "Suck It Up" Phase
When you start losing fat, there will be a period when your body fights back, partly by messing with leptin. Soon, leptin sensitivity increases, and everything gets balanced out.
But there is a "suck it up" period as you and your doomsday-prepper body come to an agreement. Increase protein and DHA intake and this phase won't last as long or be as painful. If you're still struggling, add a few additional appetite-calming measures, like these.
