How I do this? I need to lose weight ASAP. My sugar readings are in the 300's not because what I eat but because It is hard to exercise due to injury.
There is something wrong with what you're eating...what ARE you eating? Here's what you SHOULD eat....protein, fine if not beef,chicken or pork but at least eggs, and well sourced fish. Vegetables, stay away from potatoes. For now, little to no fruit. Plenty of good fat sources...pastured butter, olive oil, avocado. IF you are eating any processed whole grain garbage the Diabetes folks are telling you to eat, STOP. Best of luck to you. What will help will be if you post an average day or two of what you are currently eating.
You could certainly do a ovo-pescetarian paleo diet, no problem. Veggies, fish, eggs...
Sugar readings in the 300s however are a very serious problem. That's a diet problem, not an exercise problem. It's major metabolic derangement. Definitely give your diet (your dietary preferences, ahem, vegetarianism) a good hard look. Is it worth dying for?
