Losing weight with type 2 diabetes isn’t just about willpower—it’s about having the right tools, support, and medical insight. According to Dr. Jennah Siwak, a board-certified obesity medicine specialist and trusted voice in the GLP-1 medication community on TikTok (@WeightDoc), sustainable weight loss requires a practical, compassionate, and evidence-based approach.
With her clinical expertise and deep understanding of the emotional and physical challenges her patients face, Dr. Siwak helps individuals focus on long-term health rather than quick fixes. In this guide, she outlines strategies for weight loss that go beyond aesthetics—targeting improvements in blood sugar control and reducing the risk of serious complications like heart disease, kidney damage, and nerve issues. Her advice is both science-backed and refreshingly realistic.

Nutrition Quality Over Diabetes Labels
“There is no single ‘best’ diet or macronutrient breakdown proven to work for everyone with diabetes,” says Dr. Jennah Siwak, a board-certified obesity medicine specialist. Instead of chasing diet trends, she encourages focusing on the quality of food. That means centering meals around non-starchy vegetables, fruits, legumes, whole grains, nuts, and seeds—while limiting red meat, sugary drinks, refined carbs, and ultra-processed foods.
Heart-healthy eating patterns like the Mediterranean and DASH diets are frequently recommended because diabetes and obesity are strong risk factors for cardiovascular disease. “The best diet is the one you can stick with,” Dr. Siwak emphasizes. Extreme restrictions may lead to short-term success, but sustainability is key. For individualized support, she often refers patients to registered dietitians with expertise in diabetes and obesity care.
Don’t Overlook Sleep
Sleep plays a critical yet often underestimated role in weight and blood sugar regulation. “Poor sleep and untreated sleep disorders, like obstructive sleep apnea, can disrupt appetite hormones like leptin and ghrelin,” Dr. Siwak explains.
Low leptin can lead to reduced satiety, while high ghrelin increases hunger—making it harder to manage both weight and glucose levels. Chronic sleep deprivation also reduces energy and motivation to stay active, creating a cycle that undermines health goals. Evaluating sleep patterns and addressing potential issues like OSA can be a crucial piece of the weight loss puzzle.
GLP-1 Medications: One Tool Among Many
GLP-1 receptor agonists—such as Ozempic, Wegovy, and Mounjaro—can be powerful tools in managing type 2 diabetes and obesity. “These medications slow gastric emptying, increase feelings of fullness, and help regulate blood sugar by acting on the pancreas,” says Dr. Siwak.
But medication isn’t a magic fix. It must be part of a comprehensive plan that includes behavior change, nutrition, activity, and emotional support. “GLP-1s are incredibly helpful, but they work best when paired with lifestyle interventions,” she adds.
Mental Health Is Part of the Process
Weight loss and diabetes management aren’t just physical challenges—they come with emotional weight, too. “Many people expect that losing weight will solve everything, and when it doesn’t, they’re left disappointed,” Dr. Siwak notes.
That emotional gap can affect self-esteem, body image, and mental health. Stress, in particular, can disrupt sleep, diet, and motivation. “That’s why I often refer patients to therapists or behavioral health specialists,” she says. Building a strong support system and addressing emotional barriers can make healthy habits more sustainable.
Progress Takes Time—and That’s Okay
In an era of quick-fix weight loss transformations, Dr. Siwak encourages her patients to avoid comparisons. “Losing more than 1% of your body weight per week isn’t ideal—it can lead to muscle loss, fatigue, and other side effects,” she says.
Instead, slow, steady progress is safer and more sustainable. She urges patients to focus on non-scale victories: improved A1C, cholesterol, liver enzymes, and overall well-being. “Even if the scale doesn’t move quickly, your health might be improving in powerful ways,” she explains.
Everyone’s Journey Is Different
Early intervention often yields better results, but even for those with long-standing diabetes, weight loss has benefits. “Type 2 diabetes involves a gradual decline in pancreatic beta-cell function,” Dr. Siwak explains. “That means even with weight loss, some people will still need medication.”
This reality can feel discouraging, but it doesn’t mean efforts are wasted. Modest weight loss can significantly improve glucose control and reduce the risk of complications—even if it doesn’t eliminate the need for medication.
It’s Not Your Fault
One of the most damaging myths about type 2 diabetes is that it’s solely caused by poor lifestyle choices. “There’s a strong genetic component to diabetes,” says Dr. Siwak. “It’s not just about behavior.”
She compares it to a lock-and-key: genetics create the lock, and lifestyle can act as the key. Healthy choices can reduce risk and improve outcomes, but they can’t always prevent the disease. Blame and shame are not just unhelpful—they’re often based on misinformation.
Frequently Asked Questions
Why is weight loss important for managing type 2 diabetes?
Losing weight can improve blood sugar control, reduce insulin resistance, and lower the risk of complications like heart disease and kidney problems.
What is the best diet for weight loss with type 2 diabetes?
There is no one-size-fits-all diet. Focus on high-quality nutrition, including plenty of non-starchy vegetables, whole grains, fruits, legumes, nuts, and seeds, while limiting processed foods and sugary drinks.
Can medications help with weight loss in diabetes?
Yes, medications like GLP-1 receptor agonists (e.g., Ozempic, Wegovy) can help by reducing appetite and improving blood sugar control, but they work best alongside lifestyle changes.
How does sleep affect weight and diabetes?
Poor sleep can disrupt hormones that regulate hunger and fullness, making weight management and blood sugar control harder. Addressing sleep issues is important for overall health.
How quickly should I aim to lose weight?
Safe and sustainable weight loss is typically around 1-2 pounds (about 0.5-1 kg) per week. Rapid weight loss can cause muscle loss and other side effects.
Will losing weight cure my diabetes?
Weight loss can greatly improve diabetes management, but it may not completely cure it, especially if the condition has progressed over many years.
Is type 2 diabetes caused by lifestyle choices alone?
No. Genetics play a significant role. While healthy habits can improve outcomes, diabetes is often influenced by inherited factors beyond lifestyle.
Conclusion
Weight loss and diabetes management don’t require perfection—they require patience, support, and a personalized plan. “Show yourself grace,” Dr. Siwak says. “Losing weight is hard, and it’s even harder with metabolic conditions like type 2 diabetes.”
A sustainable, compassionate approach that addresses nutrition, sleep, mental health, medication, and lifestyle—tailored to the individual—is the most effective path forward.
