This seems typical of some, I began nutritional ketosis 5 months ago, LCHF, 3 months of stellar success and progress in all areas of health, energy, fitness, brain, then these last 2 months I'm declining, with the worst of all being relentless fatigue and exhaustion returning (a 12 year problem for me). So perhaps time to add back some carbs/starch? Various supplements not helping and don't want to get back on that band wagon. Thus far I've been getting carbs only from veg and very little fruit, zero processed anything so no grains, wheat, breads, pasta, starch, etc. I removed the few foods I tested sensitive to. How long is a reasonable time to expect to recognize an effect from adding or cycling carbs? And any suggestions how how best to reintroduce carbs for this experiment? Thanks!
