T1D Dietitian Debunks Insulin and Weight Myths
Has it ever been suggested that insulin causes weight gain?
Perhaps there's been a feeling of clothes fitting tighter right after starting insulin, leading to the medication being blamed. This is a very common belief in the diabetes community, and frankly, it's a significant misconception that needs to be addressed! But here's the surprising truth: insulin itself doesn't directly cause individuals to gain pounds. Let's dive into why this common idea is actually a big misunderstanding and what's really happening with the body.
When an individual is first diagnosed with Type 1 diabetes, their body is essentially in a state of starvation. It cannot properly use the energy from the food consumed, especially carbohydrates. What happens then? The body attempts to rid itself of that unused energy, often through increased urination. This leads to a lot of unintended weight loss; it can feel like the body is just withering away. It's not a healthy kind of weight loss; it's a sign the body isn't getting the fuel it needs.
Then, insulin therapy begins. And suddenly, something remarkable occurs! The body can finally utilize all those nutrients it was previously missing out on. Instead of being in a constant state of starvation, the body starts to return to normal, healthy functioning. Individuals begin to feel better, have more energy, and yes, they often regain some of the weight they lost. But here's the crucial point: this weight gain isn't insulin making someone "fat." It's the body finally getting the fuel it needs to be healthy and strong, the 10 out of 10 version of an individual! It's about the body functioning the way it's supposed to, not insulin being a weight-gain culprit.
Two Fun Facts About Insulin and the Body
Let's clear up a couple of common misconceptions:
- If insulin caused weight gain, everyone with diabetes would be huge! Consider this: people with diabetes who take insulin often use what are called "super physiological" amounts. This means they are taking far more insulin than someone with a perfectly working pancreas would naturally produce. If insulin truly made individuals gain weight just by existing in their system, then everyone on insulin would be morbidly obese. But that's clearly not the case, right? This alone should prompt questioning of the common belief.
- Insulin can't build a house without bricks! Insulin is a nutrient-storing hormone, yes, but it doesn't just magically create weight out of thin air. Think of it like constructing a house: the roof doesn't just appear by snapping fingers. It requires shingles, nails, and underlayment – all the necessary materials. Insulin is like the construction worker who helps place those materials in the right spot. It mediates the storage of carbs, protein, and fat, but it requires those inputs (calories from food!) to do its job. If the "materials" (excess calories) are not provided, insulin cannot store them.
It's All About Calorie Balance, Not Just Insulin
The real secret to managing weight, whether one lives with Type 1 diabetes or Type 2 diabetes, comes down to calorie balance. Weight gain occurs when more calories are consistently consumed than the body uses. Weight loss happens when fewer calories are consistently consumed than the body uses. Insulin cannot "outdo" a calorie deficit. The body is incredibly smart; weight can even be gained without insulin through other mechanisms if there's a calorie surplus.
Some individuals believe that drastically cutting carbs will automatically lead to weight loss because it lowers insulin levels. While cutting carbs often does lead to a decrease in insulin, it also frequently leads to a decrease in total calories consumed. It's the calorie deficit that causes the weight loss, not exclusively the low insulin state. Experts have seen patients eating as little as 40 grams of carbs per day and others eating 400 grams of carbs per day, both successfully losing over 20 pounds. This demonstrates that it's about the overall energy balance, not just one hormone.
Get the Right Support
Stop believing the old myths and start focusing on what truly works for the body. It is absolutely possible to manage weight effectively while living with diabetes, whether on insulin or not. An expert has personally achieved it numerous times, and the team has helped hundreds, if not thousands, of patients successfully lose weight while living with diabetes.
If an individual is tired of blaming insulin and wants real, personalized strategies to understand their body and reach their weight goals, working with a specialized professional can make all the difference. A diabetes dietitian understands the unique challenges of managing blood sugar and weight. If you're looking for a t1d dietitian or a Type 1 diabetes dietitian, they can provide specific guidance for insulin users, helping to fine-tune nutrition around insulin needs. Similarly, a T2D dietitian or Type 2 diabetes dietitian can help navigate dietary changes for insulin sensitivity and overall health. Finding a T1D dietitian near you can provide convenient, in-person support. As a qualified Diabetes Educator, they can empower individuals with the knowledge and tools needed to make informed choices and achieve lasting results.
