The Adapt company has been ramping up the low carb information on its website and FB page. Dr Westman just taped an explanation, yet again, why he doesn't use macros if the patient needs to lose weight, and the conflicting advice on Fat Consumption, fat to eat vs coming from body, etc.
This is a 10 minute "Ask Adapt" video. https://www.facebook.com/AdaptYourLife/?ref=ts&fref=ts
There was another 20 minute video answering similar questions a few weeks ago. This is a company to sell products (I have never used them, no plans to) but they are posting good, useful general Ketogenic diet info.
