If that's something you've picked up from one of my posts on another recent thread, Michele, then I'm sorry if it got you worried x
Cambridge is totally doable. Many of us here have tried every diet under the sun, but only found great success with Cambridge - because, I think, it takes food out of the equation. That whole "What shall I have for tea?" thing becomes a non-question. You have a shake, some porridge, a bar or a soup - that's it.
And for me, that proved to be the thing that worked. No more calorie counting or totting up Points or counting Syns and realising that I hadn't got enough to have what I really wanted for tea.
Sounds odd, but you kind of have to get stuck into this diet to believe it, LOL. Once I'm in the flow - and that's the fun bit when you're a restarter like me, sigh - it's the easiest diet in the world. That's particularly because on average, you'll lose twice as much in a week as you would on something like WW or SW. That in itself is incredibly motivating.
Ketosis is an important feature of Cambridge - it makes consuming so few calories bearable. But for whatever reason, there will be days when you want to eat. If you've done any other diets, you'll already know that you can still feel ravenously hungry despite having had all your allotted points or calories for the day. But human beings are designed to function very well in times where food is in short supply. Our ancestors certainly didn't sit down to huge meals on a daily basis - and whenever the chatterbox in your head tries to tell you otherwise, in time you'll learn to tell it politely but firmly to shut up.
I think you'll be amazed by how well you can cope. Don't be put off by what anyone tells you. Everyone's dieting journey is different and how you cope depends on, as Goreygirl says,
your mindset and personal circumstances.
