Hi there, I completed the Fast800 last week (lost about 6 kilos/13lbs), then did 4:3 for week 9. Granted, it was easter, and I had chocolate and reintroduced carbs, but i didn’t go crazy for the 4 eating days – only 1 would have been over TDEE. But this week I’ve regained by 2.6kg! I could cry. I’ve immediately hopped back on the Fast800. 3 days in, I’ve lost 1.5kg, but now I’m terrified of eating normally again. And by normally, with the exception of the 1 chocolate day, I mean I’ve been sticking to principles.
I still have about 10kg to lose to get to a normal BMI, and I’m aware that prolonged Fast800 will lead me down a potentially disastrous path metabolically. So I can’t afford to regain.. i need the scale to trend downwards, even if it’s slowly.
So what do I do? I can’t Fast800 indefinitely. And it looks like I can’t 5:2, because even 4:3 means I’m regaining weight.
Does anyone know why this is happening to me, and what the answer is to continuing to lose after the Fast800?
