Your meals sound good, so first suggestion would be not to worry about weight loss, but to closely monitor your blood glucose levels to heal your diabetes first. Take readings before and after meals. I know three little sliced strawberries isn't much, but that may be enough to keep your
BG and Insulin levels high. Consider reading Dr Fung's Diabetes Code
and following Dr Westman's plan, no fruit, based on what Dr Atkins used in his clinic. Heal your body and diabetes first, bringing down fasting insulin levels will make weight loss easier. Focus on the fact you already feel better, but you need to heal the pain and inflammation you have in joints. And often people do lose inches and not pounds...going by how your clothes fit is another way to measure progress.
Second guess why weight loss is slow is that you might be on one of the many medications, prescription and OTC, that hinder weight loss. NSAIDs, even the OTC ibuprofens, May do that, and any diabetes medications, injected or oral, except metformin. Any hormone meds and BP meds too...Here's the whole list at post 4, with other adds in this thread. https://forum.lowcarber.org/showthread.php?t=453311
And I agree with Blue Ruby, try to lose the crystal light and drink plain water or tea. Some people find that AS itself hinders weight,loss, but worse the sweet taste continues your cravings for sweets. I mostly avoid them, but at holidays do make some sweetened dessert for me so I have an alternative to the sugary pies. I started LC in early August, this was the first dessert I made for Thanksgiving, though not with a cup of Splenda but about a 1/3 c. Swevre. http://www.genaw.com/lowcarb/pumpkin_bake.html
By now you should have lost most carb cravings and have less hunger, you do not have to eat three meals a day, only eat when hungry, stop when full. Another tip: Know Your Why. Read yours everyday this week, especially before meals. https://cookingketowithkristie.com/...-know-your-why/
Hang in there!
