Before we can truly fight obesity, we must first understand the cause. The problem is, we THINK we KNOW the cause. You’ve heard it a million times, right? “Just eat less and exercise more. It’s all about a simple formula, calories in vs calories out. If you are overweight or obese, it is because you lack willpower or are generally lazy.”
Unfortunately, ALL of those concepts are dead wrong. None of them get to the root of obesity, and unfortunately, leave us pursuing the wrong “solutions.”
Telling someone who is overweight to “eat less and exercise more” is like telling someone with an alcohol addiction to “just drink less” or telling someone with chronic depression to “just cheer up.” Why is this unhelpful, borderline cruel, advice continuing to be perpetuated? It is important to get to the root causes of obesity, but more importantly, to find real solutions.
Obesity is multi-factorial, it has many causes. Genetics play a role. Hormones play a more significant role. Diet also plays a significant role. You can review all the links below to learn the etiology of obesity.
As you are aware, this page promotes a low carb way of living as a treatment for obesity and weight gain. Why do I feel this is effective? What is the biggest reason we gain weight on a diet that is too high in carbohydrates?
When we eat carbohydrates, particularly those that are processed like sugar and grains, our blood glucose levels will rise. Our body then has to make a hormone called insulin, to bring down elevated blood glucose levels. Insulin takes glucose from the bloodstream and allows it to enter into the cells to be properly utilized. So why does this make you gain weight? Well, insulin is a fat storing hormone. How is this happening?
So when your body utilizes glucose, it has two options.
- Use glucose, or
- Store glucose
Now, most people don’t get active right after a meal, so very little glucose will actually be used around the time we consume a meal. The majority will be stored. There are three main places your body will store glucose.
Your body stores glucose (in its stored form) in the muscles. This is glucose that can be quickly used for exercise or activity. There is a limited space in the muscles to store glucose. Also, if you have less muscle, you store less glucose. And if you are not active, these stores can stay full, not allowing more glucose in.
Your body stores glucose (in its stored form) in the liver. This glucose is used in between meals and during sleep to keep blood glucose stable when you’re not eating. There is a very limited space in the liver to store glucose. If you stay in the fed state too long or too often, and don’t allow sufficient fasting periods, these stores can stay full, not allowing more glucose in. What is “fed state” and “fasting state?” We are in the fed state when we eat a meal and for about 4 hours thereafter. In a fed state, your body relies on glucose from the food you have recently consumed. Then you enter the fasting state, where your body relies on stored glucose from the liver. So if you eat often, such as if you eat 3 meals per day, plus snacks in between, you are in a constant fed state for the majority of your day. This keeps your liver stores full. And if you have a bedtime snack, you are even interrupting your night time fast. This is not good.
So, when muscle and liver stores are full, what happens to all of the glucose? It stores as fat! What’s worse, it stores as visceral fat, or fat around our organs, in other words, belly fat. This is dangerous. And guess what? Fat storage is unlimited. There is no end to how fat we can get.
So, is this whole picture insulin’s fault? No. Insulin’s job is to bring down blood glucose SO HIGH BLOOD SUGAR WON’T KILL YOU. The problem likely is, you are giving your body TOO MUCH GLUCOSE TO STORE. That is why it is imperative to control the amount of carbohydrates in your diet so that you do not raise insulin to very high levels. So how much glucose do we NEED to take in? Very little. The blood needs to maintain a circulating level of glucose of about 1 teaspoon (4g). We DO NOT need a bunch of carbohydrates to supply that glucose. Healthy carbohydrates, like non-starchy vegetables, as well as protein provide all the glucose our body needs. (About half of the protein we consume converts to glucose.)
What else can we do lower insulin levels? Get active. Exercise improves insulin sensitivity. In other words, the insulin your body makes will work better and you’ll need to make less. And don’t just focus on cardio (walking, jogging, etc). Build some muscle. The more muscle we have, the more our body can both burn glucose and store it. We have to use and deplete stored glucose regularly. This will allow us to replenish those stores from our meals. Daily exercise is a key to using this stored glucose.
What else helps? Spend less time in the fed state and more time in the fasted state. Go more than 4 hours between meals, avoid snacking, have a long daily fast at night by not eating within 2 hours of bedtime, all the way until you wake up the next morning. Even better, try intermittent fasting. This allows us to access and burn stored glucose in the liver. Once again, we have to use and deplete stored glucose regularly. This will allow us to replenish those stores from our meals. Daily adequate fast periods are a key to using this stored glucose. (For more information on fasting, visit my fasting page HERE.)
A high carb diet, frequent snacking and a sedentary lifestyle, is a recipe for disaster. Expect to gain a lot of weight. Expect a rapid decline in your health. Expect Type 2 diabetes in your near future. Expect your heart, kidneys and brain to suffer significant damage. Expect fatigue, depression, sleep disturbances and memory problems. Expect chronic aches and pains. Expect vision problems. Expect pain in your legs and feet. Expect urinary tract infections and yeast infections. I could really just go on and on…
How do you know if you are taking in too much glucose? Well, how much weight are you gaining? If you are gaining weight, your stores of glucose are likely full. So you have to eat less glucose, by adopting a low carb way of eating, and burn more glucose, by exercise and allowing greater fasting periods in your daily routine. Add other healthy lifestyle habits such as managing stress and getting enough sleep (learn how to HERE) to better control glucose and insulin levels.
