Hang in there. It’s only the first few days and your brain is probably in overdrive thinking about how you’re going to cope on a ‘diet’. My advise is to distract yourself – drink a glass of water or go for a walk. Try not to think of this as a diet but a change in lifestyle. And also take things step by step. Think about getting through the next few hours rather then the next 8 weeks. Look at weight loss transformations on Instagram to keep you focused & inspired too!
Failing that, I find a small piece of hard cheese helps (the size of half an index finger), or half a boiled egg. You can buy small potions from most supermarkets. I’m lucky enough to have a staff canteen so i normally have a small soup with fizzy water or small side salad with grilled chicken or fish. This keeps me full for 3-4 hours. And if I’m really struggling, I’ll have 4 (just 4!) unsalted cashew nuts to take the edge off the hunger with a glass of water.
I also don’t have much time to cook, so if I haven’t prepared anything at home, I’ll buy a small side salad and some calamari from Marks and Spencers or Pret a Manger have some great breadless, low cal salads. (sorry if Pret or M&S means nothing too you if you’re based outside of the UK). You can also get Greek and natural yogurts in small pots, so again, another portable option.
Other than that, I tend to cook on a Sunday night and divide everything up into small tupperwear boxes for packed lunches. I freeze extra portions.
Hope this helps!
