Insulin is crucial in turning food into energy and managing blood sugar levels. It is also the most important hormone when it comes to diabetes. Diabetes Mellitus comes down to the body not being able to produce enough insulin, or not being able to use it correctly (leading to high blood sugar levels and therefore diabetes and chronic kidney disease). Insulin is made in the pancreas, allowing your body to use sugar (glucose) for energy.

Understanding Insulin
Insulin's main function is to move glucose from your blood into cells through all of your body. Glucose is an energy source from both foods and drinks but is also naturally released (glycogen). It is the main source of energy for the body.
Insulin is kind of the doorkeeper for cells. Once insulin lets a cell go, blood glucose can attach to it from your bloodstream to provide it with energy.
But what happens when your body doesn't produce enough insulin? Things are starting to stagnate. Stagnation of glucose leads to high blood sugar and diabetes.
If this takes a long time (you don't provide the body with the additional insulin), DKA (Diabetes-Related Ketoacidosis) comes into place.
In short: DKA is a serious and lifethreatening, but treatable, disease. If there is not enough insulin in the body, it uses fat as it's main energy source. While this may not sound that bad, it leads to a release of ketones. High levels of ketones are life-threatening for people with diabetes, due to the fact that blood becomes more acidic, meaning the pH of the blood is too low. Immediate medical attention is required in this situation.
Your blood sugar levels are balanced between insulin (which lowers it) and glucagon (which raises it).
For now, that's all you need to know. Let's dive into the stats!
Insulin: Weight Loss, Blood Sugar - 50+ Statistics You Should Know
Insulin and Weight Loss
Individuals who are insulin-resistant are 70% more likely to have difficulty losing body weight.
Obesity is strongly associated with insulin resistance, making weight loss 50% more challenging for individuals with excess body fat.
Individuals with higher fasting insulin levels tend to have a slower metabolic rate, making weight loss 15% more challenging.
Insulin resistance is associated with a 30% decrease in fat oxidation, leading to reduced utilization of stored fat for energy.
Consuming a typical Western diet, which is usually high in added sugars, increases the risk of insulin resistance and weight gain by 30-40%.
Individuals with less insulin have a 50% lower success rate in achieving long-term weight loss than those with normal insulin sensitivity.
Intermittent fasting has been shown to improve insulin sensitivity by 20-30%, which is good news for weight loss.
Emerging research indicates that gut microbiota composition plays a significant role in modulating insulin sensitivity and may influence weight loss success.
There is growing evidence that optimizing sleep quality and duration can improve insulin sensitivity and aid in weight loss efforts.
Moderate- to vigorous-intensity physical activity has been linked to enhanced β-cell function, insulin sensitivity, and blood glucose level regulation.
Physical activity, healthy diets, and weight loss can reduce diabetes risk by 58% in people with IGT.
A diet with low to moderate saturated fat (10%-45%), high protein, low carbohydrate, and low glycemic index reduces weight and improves diabetes risk factors. Unsaturated fats (like olive oil for example) have a positive impact.
By the age of 70, skeletal muscle strength is reduced by 25–40% every decade, and muscle mass decreases by approximately 8% every decade, leading to significant declines in muscle mass and strength over time.
Insulin and Lifestyle
Lifestyle changes may help mitigate the deleterious effects of genes on diabetes risk.
Lifestyle interventions promote the regression of prediabetes to normoglycemia.
People with prediabetes should be referred to intensive diet and physical activity behavioral counseling/programs targeting a weight loss of 7% and increasing moderate-intensity physical activity to the recommended goal of 150 min/wk.
Adults 18 and older should engage in 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic physical activity (or a combination of these) per week, accumulated in bouts lasting at least 10 minutes, with muscle-strengthening activities involving major muscle groups performed on 2 or more days a week.
According to the international diabetes federation (IDF), there are nearly 500 million people with diabetes in the world, and approximately 80% of people with diabetes live in low-income and middle-income countries.
Insulin and Blood Sugar
Approximately 98 million adults in the United States have prediabetes, with elevated blood sugar levels that increase their risk of developing type 2 diabetes.
Insulin resistance, which is closely related to metabolic syndrome affects about 40% of US adults aged 18-44, contributing to impaired blood sugar control and metabolic dysfunction.
Type 2 diabetes accounts for approximately 90-95% of all diabetes cases, characterized by insulin resistance and impaired insulin secretion leading to high blood pressure.
25% of obese individuals (BMI > 35) are insulin sensitive.

Insulin and Cardiovascular Health
Insulin resistance has a direct link with future heart disease/CVD (Cardiovascular Disease).
Preventing insulin resistance could avoid approximately 42% of myocardial infarctions.
Insulin resistance has been found in approximately 30% of subjects with an early diagnosis of hypertension.
During injury, the heart undergoes a metabolic shift from utilizing fatty acids as its primary energy source to relying more on glucose. However, this metabolic adaptability is compromised in cases of insulin resistance, leading to fatty acids becoming the predominant fuel source. Consequently, this shift results in heightened uptake and accumulation of lipids in the heart, contributing to a condition known as lipotoxicity. Achieving a balance between lipid degradation and glucose oxidation may mitigate the development of diabetic cardiomyopathy.
Insulin and Mental Health
As stated by the Stanford Medicine News Center, research in 2021 showed the following:
A moderate increase in insulin resistance, as measured by the triglyceride-to-HDL ratio, is linked to an 89% increase in the rate of new cases of major depressive disorder.
Every 5-centimeter increase in abdominal fat is related to an 11% higher rate of depression.
An increase in fasting plasma glucose of 18 milligrams per deciliter of blood is associated with a 37% higher rate of depression.
Those developing prediabetes within the first two years of the study had 2.66 times the risk for major depression by the nine-year follow-up milepost, compared with the control group, who had normal fasting-glucose test results at the two-year point.
Also, 5 US studies, 8 European studies, 10 Asian studies, 2 African studies, 1 South American study, and 1 study of mixed South American and European were reviewed by the US National Library of Medicine. They agreed on the following:
Insulin therapy is significantly associated with an increased risk of depression.
90% of diabetic patients have type 2 diabetes (T2DM).
T2DM is associated with a 24% increased risk of depressive symptoms.
Depressive symptoms are most commonly seen in patients who undergo more frequent insulin injections per day.
Lastly, a study from Cambridge on the association between depression and insulin therapy concluded:
The microvascular long-term complications of diabetes come from the following therapy: Neurotherapy (39%), retinopathy (37%), and nephropathy (24%).
14% of their study population suffered from Major Depressive Disorder (MDD)
Insulin and Aging
Insulin secretion may be higher at the beginning, decreasing with age due to the decline in β-cell function and mass.
The mean age of the onset of T2D (Type 2 Diabetes) in Taiwan is approximately 58 years.
DFs are affected by at least three important factors: age, ambient plasma glucose, and body mass index (BMI).
The average age of having diabetes is in the mid-fifties.
While IR (Insulin Resistance) is directly related to age according to some studies, there are many underlying possible causes for IR.
Studies have shown that, compared with younger males (30 years old), older males (65–70 years) have reduced glucose metabolism and decreased expression of skeletal muscle glucose transporter 4 (GLUT4).
The risk of type 2 diabetes increases with age. Studies have shown that the prevalence of diabetes, impaired fasting glucose, or impaired glucose tolerance in 20 to 39-year-olds in the United States was 20.9%, whereas the prevalence in individuals from 40 to 59 years old was 46.9%, the prevalence in individuals from 40 to 59 years old was 67.4%, and the prevalence in individuals ≥ 75 years old was 75.6%
Studies have shown that there is a positive correlation between the number of skeletal muscle mitochondria and insulin sensitivity in elderly individuals.
With increasing age, the intramyocellular lipid (IMCL) content also increases gradually. Insulin helps regulate intramyocellular lipid (IMCL) levels by promoting the storage of glucose as glycogen in muscle cells. In insulin resistance, IMCL levels may increase due to reduced insulin effectiveness, potentially leading to metabolic dysfunction.
Sarcopenia, characterized by age-related decline in muscle mass and strength, is associated with an increased risk of insulin resistance.
During skeletal muscle aging, the mitochondrial protein synthesis rate decreases by 40%, contributing to mitochondrial dysfunction and insulin resistance.
Skeletal muscle mitochondria are like tiny power plants inside our muscle cells. They take in nutrients and oxygen and use them to produce energy that our muscles need to move and function. Essentially, they're the engines that help our muscles work efficiently.
Intramyocellular lipid (IMCL) refers to fat stored inside muscle cells. It's like a small reserve of energy within the muscle itself. When we need extra fuel for exercise or other activities, the muscle can tap into these stored fats to provide energy. So, IMCL serves as a local energy source specifically for muscle cells.
Conclusion
In conclusion, having a good grasp of how insulin operates in our bodies is fundamental for maintaining overall well-being and steering clear of conditions like diabetes. Insulin acts as a sort of key, allowing cells to access and utilize sugar for energy production. However, when there are glitches in insulin's functioning, it can disrupt the balance of sugar in our blood, potentially leading to complications such as insulin resistance, prediabetes, or diabetes. Throughout our exploration, we've delved into how insulin impacts various aspects of our health, including weight management, heart health, mental well-being, and the pivotal aging process.
Therefore, it's crucial to take proactive measures to ensure insulin and blood sugar levels stay in harmony. Simple lifestyle changes, such as adopting nutritious eating habits, staying physically active, finding ways to manage stress effectively, and prioritizing sufficient sleep, can play a significant role in maintaining optimal insulin sensitivity and blood sugar control. By incorporating these healthy habits into our daily lives and continually educating ourselves about how our bodies function, we can collectively work towards preventing insulin-related target issues and fostering a good health future for ourselves and generations to come.
