Sticking to a diet is hard enough when you're cooking for yourself, let alone at a restaurant or when you're hosting a dinner party. 

But now nutritionist Rhiannon Lambert has revealed her very easy hacks for social occasions that will help you stick to your diet no matter where you are eating.

And by following her simple rules, you won't need to feel guilty about straying from your weight loss goals. 

Rhiannon, who shares her advice in her first book, Re-Nourish, first reminds her readers that it's fine to make unhealthy choices as a treat if dining out or hosting friends.

But for those who don't want to feel guilty about eating food that isn't part of a strict diet for one evening, Rhiannon says she has some tips that will help you stay on track.

When it comes to eating out, her advice is to order a dish that features plenty of vegetables, ordering extra if need be, as well as avoiding extra salt.

She also says that anything grilled or steamed will be healthier than roasted or fried dishes, and advises readers to swap unhealthy sides such as chips for a side salad or extra veg.

When it comes to dinner parties, her tips include asking guests to bring their own drinks so you can avoid alcohol if you wish.

She also advises making two desserts - a virtuous fruit-based option and a healthy twist on an indulgent classic. That way, you can pick the guilt-free dish while those who want something more substantial can pick the other option.

Rhiannon said: 'These days, there are loads of amazing options on menus to cater for all tastes and preferences. 

'If you’re the type of person who lets others make decisions for you, then you may need to give yourself a nudge.'

With regards to dinner parties, she added: 'I have one client in particular who springs to mind here, who has the warmest soul and would go out of her way to ensure her guests had everything they wanted. 

'She would buy chocolates for dessert, make food she wasn’t comfortable eating and put herself through a night of raised tension, anxiety, guilt and then shame. 

'This led to a day of restriction the next day to compensate for the night before. 

'It does not have to be like that; you can make your own decisions.'
