Why Knowing What to Do Isn’t Enough: When effort no longer matches results
by Dr Paula Diab, PhD, CDCES Diabetologist & Weight Management Specialist
One of the most common frustrations I hear from people living with diabetes or trying to manage their weight is this:
“I know what I’m supposed to do… I just can’t seem to do it consistently.”
For many, this statement is accompanied by guilt, shame, frustration, or a sense of personal failure. But perhaps one of the most important things we can recognise in diabetes and weight care is that knowledge alone is rarely enough.
Most people already know the basics.
They know they should move more, eat more mindfully, sleep better, reduce stress, pre-bolus, track carbohydrates, prioritise protein, or avoid late-night snacking. Yet even with excellent education and the best intentions, many still struggle to apply these strategies consistently in daily life.
Why?
Because health management does not happen in a textbook. It happens in real life.
It happens during busy workdays, school runs, interrupted sleep, emotional stress, financial pressure, relationship struggles, travel, illness, hormonal shifts, grief, exhaustion, and decision fatigue. It happens when someone is trying to care for everyone else while barely having enough energy to care for themselves.
This is where the gap between knowing and doing often appears.
The Hidden Mental Load
In both diabetes and weight management, we often underestimate the emotional and mental load involved. A person living with diabetes may make hundreds of health-related decisions every day:
- Should I correct now or wait?
- Did I count that meal accurately?
- Why am I high despite doing everything “right”?
- Will exercise make me go low later?
- Is this hunger physical, emotional, or exhaustion?
At the same time, someone trying to lose weight may be carrying a constant internal dialogue around food, body image, motivation, progress, and self-worth.
Over time, this becomes exhausting.
Few things are more discouraging than putting in significant effort – tracking meals, exercising, taking medication, making better choices – only for the scale to stop moving. Many people interpret this as failure or assume they have “lost motivation.” In reality, plateaus are a normal part of physiology and long-term change.
Our bodies are biologically designed to resist weight loss. As weight decreases, appetite hormones shift, energy expenditure changes, and the body attempts to restore balance. Add the daily demands of diabetes management, and it is not surprising that burnout can develop.
Importantly, burnout does not mean someone is lazy, weak, or lacks willpower. Often, it simply means they are tired.
This is why shame-based approaches rarely help. Most people do not need more criticism or more reminders about what they “should” be doing. They already know. What they often need is support, structure, encouragement, and realistic expectations.
This is also why medications such as GLP-1 therapies can feel so transformative for some individuals—not because they magically create discipline, but because they may reduce some of the biological and mental burden. Many patients describe less “food noise,” fewer intrusive thoughts about eating, and more mental space to make intentional decisions. But even then, medications do not eliminate the need for habits, support systems, or self-compassion.
Sustainable progress in diabetes and weight care is rarely about perfection. More often, it comes from small, consistent behaviours repeated over time:
- Pre-bolusing one meal more consistently
- Adding protein earlier in the day
- Walking after dinner
- Recognising emotional eating patterns
- Restarting after a difficult week instead of giving up completely
These may seem like small victories, but they are often the very things that create meaningful long-term change.
Redefining Success
At IDS, we often remind people that success is not defined solely by the scale, an HbA1c, or a Time in Range report.
Progress may also look like:
- fewer episodes of burnout
- improved confidence around food
- less glucose variability
- more energy
- reduced guilt
- or simply feeling more in control again
Because ultimately, success in diabetes and weight management is not simply about knowing what to do.
It is about finding sustainable ways to keep going in the middle of real life—even when progress feels slow, motivation fades, or the scale stops moving.
