What do body composition and bank accounts have in common? Most people will agree that body composition fluctuates depending on how much we deposit and how much we withdraw. Our bank account are very similar with one key and very important difference. When we deposit $500 into our bank account we are able to withdraw that money anytime we see fit. This is not the case when it comes to body fat.
In order to deposit body fat, or store it, our body has to raise insulin levels. Insulin helps maintain blood sugar levels, which are tightly regulated. As we eat most foods, blood sugar or blood glucose will start to go up. Our body senses blood sugar going up and more insulin is produced to keep it in a normal range. Insulin does this by pushing glucose (sugar) into muscles, organs, and tissue, where it is available for energy production. Glucose is one of two fuel sources our body can use to create energy, however our muscles and organs can only store a small amount of it. In order to regulate blood sugar, our body has to store any excess blood sugar as body fat, or it makes a deposit.
Withdrawing body fat is very different for everybody. This is because no two people have the exact same hormone levels. Everyone’s bodies react differently to changing environments. The easiest way I know to explain it is everybody has a time restriction between when they can deposit and when they can withdraw. Some people may be able to withdraw body fat only after a few hours after they have made a deposit. While others may need to wait 12 hours between deposit and withdraw. It all depends on our hormones. The good news for all of us, there are ways of decreasing the time. This can be through exercise, changes in diet, how often we eat, and even through the amount of sleep we get at night. Changes in any one of these areas may make huge differences for us.
Exercise: Exercise is one way to lower insulin levels. As we exercise, our bodies will use its stored glucose as fuel. Insulin is needed to push glucose into our cells and the more we use, the lower it gets.
Diet changes: One of the fastest ways to lower insulin levels, is not to produce it. We produce insulin according to what we eat. Foods that contain or simulate high amounts of sugar will produce a larger insulin responses. Foods with lower amounts of sugar that contain fiber and/or protein, will produce lower amounts of insulin. Eating some fats and not eating at all, will produce no insulin. I am a big promoter of fasting, but it is not necessary to lose fat. What is necessary is getting our hormones to levels that promote fat loss.
Sleep: Getting the right amount of sleep allows our hormone levels to reach desired levels. Too little sleep can result in higher than normal amounts of cortisol, which is directly proportional to insulin. If cortisol goes up, so does insulin.
I mentioned before that glucose was one of two fuel sources. Ketones are the other. When our bodies use fat for fuel, our liver metabolizes fat and converts it into ketone bodies. Ketones are used by our muscles, tissue, organs, and brain. The key difference is that insulin is not required for our bodies to use these ketones for fuel, unlike glucose. This is the key, insulin, which stores fat, is not required when we use ketones for fuel. Want to know more about ketones? Watch this 5 minute video Ketones explained
I hope this helps to better understand body fat and how we make deposits and withdraws.
