A common misconception among people with diabetes is that taking prescribed medications and maintaining an exercise routine can compensate for poor dietary choices. However, medical experts warn that this approach is a recipe for long-term health complications, even if one feels fine in the short term.
The Hidden Danger of Unplanned Eating
This critical issue was highlighted when a user on Quora asked: ‘What really happens when someone with diabetes ignores dietary advice but continues taking medicines and working out?’ To provide a professional perspective, we consulted Dr. Vijay Negalur, Head of Diabetology at KIMS Hospitals in Thane.
Dr. Negalur clarified a vital point. "Exercise is beneficial, but it cannot completely neutralise the impact of frequent high-carbohydrate meals, sugary snacks, or consistently large portions," he stated. The body faces repeated spikes in blood glucose when food intake is not monitored, despite the action of medicines. Over time, this forces the pancreas to overwork and can render medications less effective.
Many individuals believe they are "doing enough" by adhering to their pill schedule and going for walks. "But unplanned eating quietly raises sugar levels throughout the day," Dr. Negalur emphasised. While medications help the body use insulin more efficiently and lower overall glucose, "they can’t handle sudden spikes caused by heavy meals or desserts."
Long-Term Consequences of Ignoring Food Guidelines
The expert detailed the cascade of problems that arise from consistently ignoring dietary guidelines. Constantly fluctuating sugar levels significantly increase the risk of nerve damage (neuropathy), kidney strain, and accelerated fat buildup in the liver.
"Weight gain becomes harder to control, and cholesterol levels may rise," Dr. Negalur added. Beyond clinical metrics, quality of life suffers. Patients often report persistent tiredness, brain fog, slow wound healing, and disturbed sleep patterns.
The most significant concern is the progression of the disease itself. "The biggest concern is that poor eating habits can push the condition from controlled diabetes to uncontrolled diabetes, even if medicines are taken on time," he warned. Uncontrolled food intake leads to higher fasting and post-meal sugar readings, which eventually necessitates stronger medication.
The Powerful Synergy of Diet and Exercise
Is there a benefit to following dietary guidance when someone is already exercising? The answer is a resounding yes. A balanced diet makes medications work more effectively, ensures consistent energy levels throughout the day, and prevents drastic sugar swings.
"Small changes, like reducing refined carbs, keeping portion sizes steady, or adding fibre-rich foods, can greatly improve sugar control," advised Dr. Negalur. This mindful eating also amplifies the benefits of physical workouts, helping the body burn fat more efficiently.
For those who tend to "eat freely," the doctor offers a practical strategy: focus on portion awareness rather than complete deprivation. "Planning meals, reading nutrition labels, and limiting sugary extras can make a noticeable difference. Even a few mindful choices each day can protect the body from long-term complications and make diabetes easier to manage," he concluded.
