Did you try just having 2-3 hard boiled eggs fir breakfast & one boiled sweet potato for lunch followed with a cucumber salad....

Why don't you close it all with a few cups of green tea for thevrest ofbthe day :

There’s a wealth of research on how green tea may help with weight loss and thus help people with type 2 diabetes get their blood sugar under control. It depends on the variety, but a plain cup of green tea from a steeped bag contains 0 calories, according to U.S. Department of Agriculture nutrition data. That means it’s a great alternative to sugary and caloric sodas and energy drinks.

“When you lose weight, you increase your insulin sensitivity and will have a lower blood sugar level,” says Sandra Arevalo, MPH, RDN, a certified diabetes educator based in Hilton Head, South Carolina, and spokesperson for the American Association of Diabetes Educators. A study published in the Journal of Research in Medical Sciences looked at different doses of green tea in 63 people with type 2 diabetes. Researchers found that drinking 4 cups per day was linked to weight loss and lower blood pressure.

Toby Smithson, RDN, CDE, author of Diabetes Meal Planning and Nutrition for Dummies, explains that the catechins in green tea help reduce the effects of insulin resistance by decreasing the digestion and absorption of carbohydrates. (Catechins are a type of antioxidant.) A study published in September 2014 in the Iranian Journal of Medical Sciences suggests that drinking green tea regularly — participants drank a 150-milliliter infusion three times per day for four weeks — had a positive effect on insulin resistance in people with diabetes and increased their HDL ("good") cholesterol levels. An infusion of 3 grams (g) of tea leaves in 5 ounces of water is stronger than a regular cup of green tea (2 g of tea leaves brewed in 8 ounces of water), but Smithson, who is also based in Hilton Head, South Carolina, says it’s possible to get the same benefits listed in the study by drinking several cups of regular green tea per day. But, she points out, green tea alone is unlikely to control blood sugar and cholesterol levels — you’ll need to eat a balanced diet that’s low in added sugars, simple carbohydrates, and saturated fat and monitor your numbers regularly.

Yes, because to me, breakfast is the time for pastry, or bagels or pancakes, none of which I can have now.

Years leading up to getting told D inuse to crave a lot of beef n broccoli it was one of those combo foods that i wonted sooo badly (mostly around the time i was to have a cycle).
But never really had a issue figuing out what to have for breakfast. I mostly didn't change anything after getting told.
Breakfast is still one of a few options... tofu scramble, waffle sticks, pancakes, cereals (pops, chex, rice krispies) with soy milk or a protein fruit smoothie. Glucose wise taken a few to learn my needs but after 20 years ive got a good idea of how it works for me and managed to get my a1c under 6 n keep it there since 2012.

Update....I no longer eat a big breakfast. I only eat 1 meal a day and that is dinner.
