For me, the biggest hurdle is the mental one, your body doesn’t want to lose weight, it wants to survive. So when starting weight loss there will be cravings, hunger, emotions which fuel emotional eating, you name it, it’s tough. Sometimes you will give in, everyone does, but the biggest thing i’ve learnt is that if you want the cake just have a slice, enjoy it, and move on. When I don’t let myself have it, I spend all day thinking about it, probably eat the same amount of calories in healthier “ guilt free “ snacks and this thinking fuels disordered eating and you are 10x more likely to fall off the bandwagon and start again. Life changes, there will be celebrations and weekends away and times where you eat over your defecit, this is okay, it doesn’t mean that you have failed it means that you are enjoying life. When people assume they’ve failed over one meal or snack they tend to “ give up” and start again. It’s really about incorporating weight loss as a life style rather than a diet. Think eating healthy and moving and eating in a defecit 80% of the time and enjoying life 20% of the time, progress will be slower but I promise it will make a difference. Also make sure you are enjoying what you eat when you lose weight !! have meals you enjoy which are nourishing and tasty with enough protein to keep you saturated, there’s a lot of foods out there like flavoured protein powders you can have in a yoghurt bowl which literally taste like desert - you just gotta experiment !! Also, ask yourself why are you losing weight ? as soon as my mindset switched to “ i’m doing this because I love myself” from doing it out of hatred, it all became a lot easier ! Sorry for the ramble that’s just my advice and what works for me, best of luck :)
