There’s plenty of low-carb foods out there. Have you ever seen a dietitian? Not a nutritionist, but a registered dietitian? I learned a lot from the one I saw!
For me, since I cannot exercise, it was cutting out anything I didn’t get nutrition from (sodas, sweets), cutting down on the carbs by eating more whole wheat and less starchy foods, and by portion control. I’m losing less than a pound a week, which is a good rate, but I’m still losing! I test my blood a lot to keep track of what foods cause spikes and which don’t. Potatoes are evil creatures! I get less of a spike from pasta!
I also watch the fat intake although it is low on the priority list. I use portion control more with meat than with veggies.
