My patient, Latha, had Type 2 diabetes and was on daily insulin shots. Her body weight was well above the normal range. Usually Type 2 diabetes patients can use both insulin and GLP-1 drugs, and combining them is a common and effective treatment strategy. But once she was on GLP-1 therapy, she didn’t need insulin anymore. She had better blood sugar control, experienced weight loss and had a reduced risk of hypoglycemia or blood sugar plunges.
Now there has been enough talk about GLP-1 drugs, which mimic the GLP-1 hormone to treat Type 2 diabetes and obesity. They work by increasing insulin production, slowing digestion and promoting feelings of fullness, all of which help lower blood sugar, reduce appetite and lead to weight loss. But I am writing about Latha because she did not treat it like a magic pill. She added lifestyle discipline to it.
What GLP-1 therapy does
It works with your body’s own hormonal system. When used correctly and consistently, it can create a powerful shift in glucose control and weight regulation. One of the major benefits of the medication for Latha was that it improved her satiety signals. “I remember feeling full much faster — not the usual cravings I used to battle every day,” she told me. For someone like her, who had long-standing insulin usage and insulin resistance, this meant her body finally got a chance to respond properly.
As she lost weight, her cells became more sensitive to her natural insulin. That’s why we could slowly reduce and eventually stop her insulin injections. “That was the biggest change for me. Earlier I never understood why I needed so much insulin even when I controlled my food. I felt like no matter what I did, nothing moved,” she told me.
This feeling is common in advanced insulin resistance. But with GLP-1 therapy, weight loss is not just cosmetic — it fundamentally changes metabolism. Your liver responds better, your muscle cells take up glucose more efficiently, and your pancreas doesn’t need to overwork. Everything becomes smoother. Latha’s sugar levels were more predictable. There weren’t constant swings and her HbA1c (average blood sugar count for three months) came down. Her fasting blood sugar levels improved and her post-meal spikes reduced. Her body started regulating glucose naturally again.
What needs to be done to maintain efficacy of GLP-1 drugs?
GLP-1 therapy sets the physiological foundation but Latha made lifestyle changes that amplified the benefits. She stayed consistent with her meals, increased her physical activity and didn’t miss follow-ups. That combination made the results possible.

So, what did Latha do? First, she kept to her meal times, switching over to a high-protein diet. She teamed that with resistance training to preserve muscle mass, as the drug does wear them out badly as a side effect. She began to eat smaller, more frequent meals of nutrient-dense foods so that she could avoid nausea, upped her fibre intake and drank water and fluids to prevent constipation, both side effects of the drug.
Additionally, she took up resistance training thrice a week and alternated it with aerobic exercises. Bodyweight exercises like squats and push-ups or resistance bands are a safer and more accessible option. These will help you maintain your muscles, which are necessary to preserve your metabolism during weight loss.
Latha did yoga and meditation for stress management and slept at the same time every night, between 9.30 pm and 10 pm.
The latest WHO guidelines on GLP-1 therapy re-emphasise the role of diet, exercise and lifestyle in consolidating the gains made from medication. It doesn’t matter if you had not made these changes before. Begin with small, sustainable steps and see the big change. The medicine is just an accelerator.
