Hi
@Don66,
Based on my reading and experience as a T!D, not as health professional advice or opinion:
Insulin tends to put carbs in excess of those needed for energy into fat cells.
And weight gain may increase the need for more insulin and so the cycle may continue.
In the past diabetics were advised to lower fat intake in the mistaken belief that fat caused heart disease and this led to more carbs being eaten, more insulin, increased weight and so on.
With more modern thinking and debunking of some of the myths about heart disease etc the wheel seems to be turning around to a diet of less carbs and more protein and fat.
We even know now that our brain does not need 150 G of carbs per day to function. Only perhaps a 1/5 of that.
And if you think say 30 grams of carb per day is not enough, the discovery of the lower needs for carbs relates back to the fact that the Inuit, Laplanders and such tribes existed for centuries on zero carbs and just protein and fat.
What has emerged are the reappearance of low carb diets and ketogenic diets (keto- for short).
If you were to read the book or e-book Dr Bernstein's Diabetes Solution and dietdoctor.com you will find how the low carb and keto- diets help lower BSLs, reduce hypos and help reduce weight.
Of course being on insulin the advice of your prescribing doctor or nurse is advised since eating less carbs means that less insulin is required, and excess insulin could lead to hypos.
Some choose to lower their carb intake to say 100g, or 80 g or 50 g per day and according to sites like dietdoctor.com these amounts do not lead to what is so-called nutritional ketosis (or fat burning). But people have succeed in losing weight with appropriate insulin reduction.
Others choose to go very low carb, around 30 g per day. The details are on the 2 references above. And people can change into the fat burning state which helps with weight loss. etc.
You may not find your doctor or nurse are conversant with keto or low carb diets or may be reluctant or resistant to the idea of these diets because they are still be tied to the fat causes heart disease belief.
So you have choices about the way you might proceed with your weight loss plans. Higher carb with adjusted insulin as per your health team ( and suggested by @Diabell) or the lower carb options or some other option.
I fully agree with
@Mbaker's approach with the same sort of foods used on a low carb or keto diet, includes healthly choices such as exercise, relaxation, socialisation etc.
Best Wishes
