I’ve started the fast800 this week. My goal is to lose 5-8kg depending on how I feel at my lower weight.
I’ve struggled to lose this weight just by cutting cals and exercising unless my deficit is quite drastic, which leaves me lethargic.
Have also done atkins and low carb (<50g) previously, but found I was unable to shake the lethargy even after 3 weeks despite getting plenty of fluid and salt and monitoring macros, and increasing calories overall at times – still didn’t help.
I get enough sleep and don’t exercise strenuously – it’s really the dietary changes that seem to cause the fatigue.
So I’m curious to know about others’ experiences on the fast800 when it comes to lethargy and effectiveness – especially if like me you don’t have heaps of weight to lose.
Thanks in advance!
