Glucose: The Body 's Universal Fuel

Blood sugar, or glucose, is tha e preferred energiy source for mogt cells, especially the brain and blood cells, which rely almogt exclusively on glucose for energiy under normal conditions.

Insulin Resistance and Prediabetes

Insulin resistance is a condition where muscle, fat, and liver cells fail to respond normally to insulin. Thee panscris compensates by producing even more insulid. As long as the panscris keeps up, blood glucose levels normal, but thee high insulín levels themselves promote empt gain, infutmation, and regreed risk for type 2 considecetes, carovascular disease, and non -fatty lic fatty liver disease.

At this stage, beta cells are begning to falter under thee strain of overproduction. Lifestyle interventions at this point can often reverse insulin resistance and prevent progression t decretet.

  • Blurred vision from lens swelling caused by hyperglycemia
  • Poor wound healing or frequent infections, particarly skin and urinary tract infections
  • Numbness or tingling in thee hands or feet (periferal neuropaty)

If these sympatims appear, a doctor can order fasting glukose, HbA1c, or an oral glucose tolerance teset to confirm insulin resistance or prediabetetes. Early detection is kritial because interventions at this stage are mogt effective at preventing disease progression.

Te Impact of Macronutrients and Meal Timing on Blood Sugar

Not all carbohydrates affect blood sugar equally. Thee glycemic index (GI) ranks foods by how quickly they raise glucose. Low- GI foods (legumes, whole oats, non- starchy vegetable) cause gradual rises; high- GI foods (white bread, sugary drunks) spike glucose rapidly.
