Thanks Tot , I've been reading quite a lot by Lyle and indeed Pasquale- the stubborn fat solution is kind of in the background as something I can phase into with this current diet tbh . Metabolic slowdown through age and a sustained period of dieting have ensured little wiggle room at present , I'm hoping the addon cardio sessions will dispel another couple of pounds in the next number of weeks. After that I'm looking at hitting sub 100 grams carbs for sure and increasing protein by whatever amount of carbs I reduce. Conditioning is the end all be all nowadays so all options are under consideration to get there. I'll reduce carbs once things stall out on the present plan ,hoping to get the max amount of benefit from small reductions in carbs for as long as possible.
The rapid fat loss setup is also something I can look at but only as a once off , but it's a viable once off if need be.
