I had good success on it along with the “4 hour Body” from Tim Ferris
It was coming up for 7.5 years ago now (My son will be 8 in May and I was on it prior to him arriving)
I lost 19lbs of fat in 3 months being very strict on it, with no excercise at all.
I gradually slipped back into old habits over a few years, developing Thyroid issues and their associated drug treatments really have not helped weight loss either.
I really need to give it another go as I found it was sustainable and really worked for me.
It’ll be interesting to see if it`ll work again despite the thyroid medication.
Holiday in 6 weeks so to drop a stone would make me feel much less body conscious round the pool too
