Having eaten our way through the festive season, our thoughts reluctantly turn to 2016 and the uphill diet struggle that lies ahead.
Of course, there's always a plus side – the one here being that, no matter what happens, we'll never have to survive on water and cayenne pepper like poor Beyoncé.
Celebrities have gone to some fairly extreme lengths to achieve their red-carpet worthy bodies – it seems having iron-cast willpower is a prerequisite for an A-lister.
Here's a look at some of the more bizarre celebrity eating regimes…
The Master Cleanse
What it is: Lemon juice, maple syrup, cayenne pepper and water are mixed into a special drink, of which almost two litres must be consumed every day. This is combined with a special laxative tea to keep things moving.
Celeb fans: Beyoncé famously used this diet to shed the pounds for her role in Dreamgirls, and again before her appearance at the 20015 Met Gala.
The Baby Food Diet
What it is: One of more meals a day is substituted for baby food, which in theory seems like it could be a good idea. After all, food intended for babies is probably super-healthy, right? Yes, but it's also devoid of taste and texture.
Celeb fans: Jennifer Aniston and Reese Witherspoon have reportedly given this faddy diet a go.
What it is: One meal a day is swapped for a mushroom-based substitute, apparently helping you to lose excess weight around your tummy, thighs, upper arms and bottom, while maintaining your curves.
Celeb fans: Katy Perry and Kelly Osbourne are both M-Plan fans.
The Alkaline Diet
What it is: Alkaline dieters avoid acid-producing foods that can cause the body to stress out. Recipes on the alkaline programme are mainly based on fresh fruit and vegetables, while coffee, junk food, sugar, salt and alcohol are major no-no's.
Celeb fans: Victoria Beckham reportedly swears by this eating plan.
The Blood Type Diet
What it is: This diet, created by naturopath Peter D'Adamo, is based on the suggestion that particular foods have different chemical reactions depending on our blood type. For example, those with Type A blood should avoid meat altogether, while Type B can eat certain meats.
Celeb fans: Miranda Kerr (a Type A, doncha know) follows this regime to keep her catwalk queen figure in check.
