That's the spirit Tori! The first four days are generally the hardest as your body goes into ketosis (which is when your body starts using up stored fat) BUT from day 4, when you're in ketosis, you probably won't feel hungry any more but the mental battle will begin ..... Your mind starts wailing that it just wants to taste something NOW. Prepare yourself and plan ahead, drink lots of water (I think people are starting off with 2 litres a day), be prepared to pee a lot unless you're used to drinking a lot* of water but don't worry, this tapers off as your body gets used to the new regime.
Try to space out and time your shakes so one is due when you start to get hungry (listening to my body, I'd say every 4 hours is my personal limit, some can do 5 hours and some can go even longer).
And the biggest thing I wish I could time travel and tell myself (so I'll tell you instead) is: no matter what do not cheat! A controlled re-feed for Christmas day or something is one thing, but do not under any other circumstances give yourself permission to eat until you get to goal and DO maintenance. Trying and failing to get back to that VLCD (Very Low Calorie Diet) virgin state, where you're excited by your losses and unsure what to expect but determined to get there anyway, is so difficult it's quite literally a nightmare.
This diet is unbelievable - the first week will be your biggest loss (pounds + initial water weight), but on average you will lose 14 pounds a month. I don't do Any exercise for the first month because you're really not taking in enough calories to sustain a workout and your body is just learning (after years, in my case, of overeating) that there's a "new sherrif" in town.
The first week is the hardest, and conversely it's the week you'll be strongest i.e the closest to the weight you don't want to be so more determined to stay the course. Biggest tip: get as many early nights as you can get away with in week 1. Drink your water, write out all the reasons you're doing this - or better yet take a naked selfie and look at it whenever temptation calls
and if all else fails? Come on here and read diary threads and inspirational stories.
But above all, I want to say "Well done" on making the decision to do this one special loving thing for yourself..... 65kg here you come! x
