I've been on a diet since having a heart attack in April and have lost over 40lbs to date. I switched my diet to a liberal keto diet at the start of September and lost 9lbs in that month.
What was interesting is that I don't recall being hungry at any point in September, it was quite remarkable.
Now, last night we had some roasted veg (mainly butternut squash) and some pork patties. I realise squash isn't particularly keto friendly but it is very nutritious.
Anyway, this morning I'm famished and my stomach is growling constantly. There really is something in this.
