Insulin Resistance & Stubborn Weight
When your body stops responding to diet and exercise, the problem is hormonal. Insulin resistance keeps fat locked in storage regardless of how hard you try. Targeted medical treatment changes the equation.
What is insulin resistance?
Insulin resistance occurs when your cells stop responding efficiently to insulin, the hormone responsible for moving glucose from your bloodstream into your cells for energy. When cells become resistant, your pancreas compensates by producing more insulin. Chronically elevated insulin levels signal your body to store fat, particularly around the midsection, and make it extraordinarily difficult to lose weight through calorie restriction alone.
This condition affects an estimated 40% of adults between 18 and 44 and is a precursor to type 2 diabetes, cardiovascular disease, and metabolic syndrome. Many people with insulin resistance have no idea they have it. They experience stubborn belly fat, intense carbohydrate cravings, energy crashes after meals, and frustration with diets that work for everyone else but not for them.
The good news is that insulin resistance is not a permanent state. It is a metabolic dysfunction that responds to the right interventions. While lifestyle changes like reduced sugar intake and increased physical activity help, they are often insufficient on their own. Medical therapies that directly improve insulin signaling and reduce circulating insulin levels can break the cycle and restore your body's ability to burn stored fat.
Common causes of insulin resistance
Chronic inflammation
Low-grade systemic inflammation interferes with insulin receptor signaling, making cells less responsive to insulin over time.
Visceral fat accumulation
Fat stored around internal organs releases inflammatory cytokines and free fatty acids that directly impair insulin sensitivity.
Sedentary lifestyle
Skeletal muscle is the largest consumer of glucose. Without regular muscle contraction, glucose uptake decreases and insulin resistance worsens.
Hormonal changes
Cortisol elevation from chronic stress, declining estrogen during perimenopause, and thyroid dysfunction all contribute to metabolic resistance.
How we treat insulin resistance
INA's approach to insulin resistance centers on GLP-1 receptor agonist therapy, the most significant advancement in metabolic medicine in the last decade. GLP-1 medications like semaglutide and tirzepatide work by mimicking a natural gut hormone that regulates blood sugar, slows gastric emptying, and reduces appetite. Crucially, they also improve insulin sensitivity at the cellular level, addressing the root dysfunction rather than masking symptoms.
Every patient begins with a comprehensive medical intake reviewed by a board-certified physician. Based on your metabolic history, BMI, and health goals, your provider will prescribe a GLP-1 protocol tailored to your physiology, with dose adjustments over time to minimize side effects while maximizing metabolic improvement. Ongoing monitoring ensures your treatment evolves as your body responds.

Warning: Compounded GLP-1s (Tirzepatide & Semaglutide)
Please contact your doctor ASAP and seek in-person care immediately if a side effect becomes problematic or you experience:
- Severe nausea and/or vomiting resulting in dehydration - it is important to stay well hydrated and drink plenty of fluids while on this medication. Kidney problems/kidney failure - vomiting, nausea, diarrhea can cause dehydration and kidney issues and make kidney problems worse in individuals who have pre-existing kidney conditions; may sometimes lead to the need for hemodialysis.
- Thyroid C-Cell Tumor: Trouble swallowing, hoarseness, a lump or swelling in your neck, or shortness of breath (see black box warning below).
- Pancreatitis: Severe pain in your abdomen or back that will not go away.
- Acute gallbladder disease: Pain in the middle or right upper stomach, fever, white parts of your eyes turn yellow or skin turns yellow, nausea/vomiting.
- Hepatitis: Elevated liver enzymes/Jaundice.
- Diabetic retinopathy problems: Changes in vision in those with type II diabetes, particularly vision problems may worsen in those with a history of diabetic retinopathy.
- Severe gastrointestinal disease: may cause gastrointestinal disease; do not use if you have a history of severe gastrointestinal disease.
