Leptin and ghrelin are both hormones that help manage weight naturally. Insulin helps regulate blood sugar levels and is also a key player in determining your weight.
The Unfair Reason Some People Struggle with Weight Loss
Have you ever had a friend who eats chocolate, pizza, and junk food every day, yet effortlessly stays skinny and attractive? I have a lot of those friends and I’m envious. If I eat a piece of cake I get bloated for the rest of the day and gain water weight. Genetics and weight loss are intricately linked in ways many of us don’t even realize and it’s why most of us struggle so much to reach our target weight.
They Can Eat Whatever They Want “Because of Genetics” But What Does That Really Mean?
There are many different hormonal and genetic reasons for why those people can eat whatever they want without getting fat. But there is 1 reason above all, that their bodies process junk food so much more effectively.
Their bodies are ultra-sensitive to a hormone called “insulin”.
Insulin is your body’s storage hormone – when it’s active your body can’t burn fat. It has to force the storage of all nutrients available in your bloodstream, like sugars, fats, proteins, and vitamins.
A major difference between foods we consider ‘junk food’ and so-called ‘healthy foods’ is they produce different insulin spikes. If you get fried chicken and French fries from McDonald’s, you’re going to get a big rush of insulin as your body tries to digest all the sugars, fats, and calories.
What happens with all those sugars, fats, and calories depends on your genetic insulin sensitivity. In people with very high insulin sensitivity, their muscles, organs, and other tissues are extremely sensitive to this hormone. They “suck up” all the sugars and fats because they’re highly sensitive to the hormone.
This also happens with people who are very active and athletic, their bones and muscles increase in insulin sensitivity so they can get the extra energy and nutrients they need to repair. But what about the rest of us?
What Happens To Junk Food When We Have Low Insulin Sensitivity?
Our other tissues aren’t very sensitive to insulin, so they ‘suck up’ less of the sugars and calories from that McDonald’s meal. Your body decides the demand is low for those nutrients, so it saves them for future use by storing them……as body fat.
As you can see, high insulin sensitivity has amazing benefits when trying to lose weight. After all, who doesn’t want to be able to stay thin while enjoying junk food?
How Can You Increase Your Insulin Sensitivity So Your Body Stores Fewer Calories As Fat?
I have some bad news, there’s not a lot you can do. The biggest factor in insulin sensitivity is your genetics and weight loss can be very challenging as a result. But that doesn’t mean you’re completely helpless. Genetics accounts for about 60-70% of your insulin sensitivity. But you can still improve that 30% with certain methods.
Unlike most metabolic hormones, which get thrown out of balance and fight against you as you lose weight, Insulin sensitivity IMPROVES as you lose weight.
Insulin Sensitivity Is Ideal At Certain Ranges Of Body Fat
For Men: 10-15% Body Fat
For Women: 19-24% Body Fat
After you lose your body fat and stay in this range for a while (without yo-yo dieting) you’ll notice you can eat a lot of foods you couldn’t before, without getting bloated or gaining weight.
It’s not a magic fix, but it does make a difference.
The Other Common Method You Can Use To Boost Your Insulin Sensitivity
…is high intensity exercise. Yes, high intensity exercise can reverse the role of genetics and weight loss in your favor!
During a 48 hour period after you exercise, your body will have artificially elevated insulin sensitivity. This is because your muscles, soft tissues, and even bone will need extra energy to repair themselves. The key word here is “high intensity”.
You need to perform the types of exercises that drain the sugar stores inside of your muscles – called glycogen. That means full body weightlifting routines or HIIT (high intensity interval training) are MUCH BETTER than standard cardio for boosting insulin sensitivity.
If you do just 3 full body routines a week, for 1 hour each session, you’ll spend 6 days a week with elevated insulin sensitivity. That’s a great payoff for a little hard work.
