Diabetes and Obesity: Breaking the 'Diabesity' Cycle

The close connection between excess body weight and Type 2 diabetes is so strong that medical researchers created a combined term for it: 'Diabesity.'

For many people, trying to lose weight while managing blood sugar feels like a frustrating cycle: high insulin levels promote fat storage, and extra body fat makes cells more resistant to insulin.

Understanding how visceral fat works—and setting realistic, modest weight goals—helps you break this cycle effectively.

The ADA (opens in a new tab) is now direct about the direction of causation running both ways: obesity worsens hyperglycemia and drives diabetes progression, and diabetes treatment can in turn worsen obesity, since some older glucose-lowering medicines cause weight gain as a side effect. That is the 'vicious cycle' diabesity actually describes — not simply two conditions that happen to overlap, but each one actively feeding the other unless the treatment plan addresses both together.

The scale of this link is enormous worldwide. The World Health Organization (opens in a new tab) reports that global obesity has nearly tripled since 1975, and higher-than-optimal body weight is now one of the leading drivers of noncommunicable disease, including Type 2 diabetes, worldwide. Excess adipose tissue — especially the visceral fat packed around abdominal organs — changes how fat cells signal to the rest of the body, releasing inflammatory chemicals and free fatty acids that blunt the ability of muscle, liver, and pancreatic cells to respond normally to insulin. That is the biological chain connecting a growing waistline to a rising fasting glucose reading.

South Asian Genetics and 'TOFI' (Thin Outside, Fat Inside)

International medical guidelines recognize that people of South Asian heritage (including Pakistanis) have a unique genetic metabolic profile:

• Lower BMI Cutoffs: While Western obesity thresholds begin at a BMI of 30 kg/m², South Asian health cutoffs define overweight at BMI > 23 kg/m² and obesity at BMI > 27.5 kg/m².
• Visceral Fat Tendency: South Asians tend to store excess fat deep around internal abdominal organs (visceral fat) rather than under the skin, even at normal overall body weights. This abdominal fat actively releases inflammatory signals that block insulin.

The Magic of a 5% to 10% Weight Loss

Many people feel discouraged because they believe they must lose 20 or 30 kilograms to see health benefits. That is completely untrue.

Clinical trials show that losing just 5% to 10% of your current body weight (for example, losing 4 to 8 kg if you weigh 80 kg) yields immense metabolic rewards:

1. 1Significantly reduces visceral liver and pancreatic fat.
2. 2Lowers HbA1c by 0.5% to 1.5%.
3. 3Improves blood pressure and cholesterol numbers.
4. 4Allows doctors to safely step down medication dosages.

“Losing just 5% of body weight frees your liver and pancreas from fat strain, transforming your blood sugar control.”

Diabetes Remission Is a Real, Documented Outcome

For people diagnosed with Type 2 diabetes within the last several years, weight loss is not only about improving numbers — it can sometimes put diabetes into remission entirely. The landmark DiRECT trial (opens in a new tab)33102-1/fulltext), published in The Lancet, put adults with recent-onset Type 2 diabetes on a structured, medically supervised low-calorie total diet replacement followed by careful food reintroduction and long-term support. Nearly half of participants achieved remission — normal blood sugar without any diabetes medication — at one year, and over a third remained in remission at two years.

The mechanism DiRECT researchers uncovered explains why the '5% to 10%' rule works: rapid, substantial weight loss first drains fat out of the liver, which restores the liver's ability to properly regulate glucose, and then draws fat out of the pancreas, allowing insulin-producing beta cells to recover and function again. This is exactly why doctors emphasize losing weight early after diagnosis — the pancreas has a better chance of bouncing back before beta cells are permanently damaged.

Treating Obesity as the Root Cause, Not a Side Issue

Diabetes care has historically focused almost entirely on lowering blood sugar, treating excess weight as a secondary lifestyle concern. That is changing. The 2026 ADA Standards of Care (opens in a new tab) now recommend that adults with overweight or obesity and Type 2 diabetes be offered a GLP-1 receptor agonist or a combined GIP/GLP-1 receptor agonist as a preferred medication class specifically because these drugs lower both weight and blood glucose together, rather than being added only after other options fail.

The ADA also highlights that these medications carry benefits reaching beyond the scale: evidence now supports protective effects on the kidneys, heart, and liver, including in people with obesity-related fatty liver disease. This reflects a broader shift in medical thinking — obesity is now treated as a root driver of diabetes that deserves direct, proactive treatment, not just a number to feel guilty about on a scale.
