If it's good enough for Jennifer Aniston then it's good enough for us.
Your definitive guide to the 5:2 diet from recipes, tips, tricks and low calorie food swaps.
What is the 5:2 diet?
The 5:2 diet plan is simple. For two non-consecutive days a week you must limit yourself to 500 calories a day (600 for men) and the rest of the time you can eat normally. Though, you may be disappointed to hear (like we were) that ‘normally’ doesn’t mean you can feast on takeaways and family-sized Galaxy bars, rather, you need to stick to the recommended daily calorie intake (2,000 for women, 2,500 for men). Celebrity fans of the 5:2 diet include Miranda Kerr and Jennifer Aniston apparently. Yes, the diet secrets of the rich and famous never cease to amaze us.
How does the 5:2 diet work?
The 5:2 diet is essentially a fancy name for intermittent fasting. Fasting is seen as a more effective way to lose weight because by cutting down on your calorie intake intermittently, rather than all at once, your body goes into ‘repair mode’ and not ‘starvation mode’. This repair mode causes the body to restore damaged cells, which uses more energy, whereas starvation mode causes your body to store fat.

What are the benefits of the 5:2 diet?
We asked nutritionists, health writers and experts what they thought about the diet that improves your cognitive function which can help to prevent conditions like Alzheimer’s and dementia. Felicity Cloake, Guardian columnist and award-winning food writer says: ‘The 5:2 diet is the only one I’ve ever tried which feels doable long-term – the idea of depriving myself of anything seven days a week is so depressing I inevitably give up, but nothing seems so terrible about fasting for a single day at a time. After all, I can always have that cake tomorrow!’
Angela Dowden, author of The 5:2 Diet Cookbook, says: ‘Fasting is a routine you can sustain and it’s adaptable too – later on you can do just one day a week to keep weight off. Also it really does seem to help re-educate your eating habits, which is key to sustained weight loss.’
Dr Sarah Schenker, author of The Fast Diet Recipe Book, says: ‘Although you will find the fasting days challenging to begin with, you quickly get used to dealing with hunger pangs and some people feel empowered by fasting, others talk of a sense of freedom or relief by not having the dilemma of choosing what to eat.’
Kate Harrison, author of The Ultimate 5:2 Diet Recipe Book, says: ‘The 5:2 is the first diet I’ve ever wanted to stick with for life – it’s incredibly simple and flexible. Plus, it’ll save you money – and, of course, you can still enjoy your favourite dishes, so 5:2 means never having to feel guilty about food again.’
How to do the 5 2 diet
We asked Kate Harrison, author of The Ultimate 5:2 Diet Recipe Book (Easy, Calorie Counted Fast Day Meals You’ll Love) for some top tips, tricks and swaps so you can make this much-talked about diet work for you. Here’s what she had to say:
Maximum flavour for minimum calories
Fast days and carbs don’t mix. A sugary croissant will eat up most of your daily allowance and leave you famished by eleven o’clock, focus instead on vegetables, salad and small servings of lean meat, fish, eggs or tofu. Why not jazz them up with herbs, spices and flavourings? Chilli flakes or curry pastes in soups, stews or baked beans; flavoured vinegars or lemon juice to dress salads, and fresh herbs as a topping for most dishes. Soups are also a great bet because they’ve been proven to fill you up for longer than the same ingredients served on a plate!
Experiment with meal times
We’re always told that breakfast is the most important meal of the day – but many of us on 5:2 find that the later we eat, the less hungry we feel so experiment with meal times to see what suits you best. Swapping three meals for two or even one gives you more calories per meal. Try brunch at 12 and supper at 6, or a bigger meal with your partner at 7pm. There’s some evidence that leaving longer between meals has bigger healthy benefits. If you like ‘traditional’ meat and two veg, flip the proportions – serve a small piece of grilled chicken or seared tuna, with two or even three big portions of veg.
Fresh ingredients are best – and cheapest
The 5:2 diet saves you money, because you’re eating less and because fresh, seasonal produce is the most satisfying and best value. Pick what’s fresh and cheap at the supermarket or market stall – those overripe tomatoes will be delicious roasted with balsamic vinegar and herbs. In winter, root veg like parsnip and butternut squash are delicious in soup or roasted and served with low-fat feta. Halved peppers can be stuffed with cream cheese, veggies or tuna, then grilled. You can even bake an egg in one.
Fast low calorie food swaps:
• Swap bananas for fresh or frozen berries in yogurt, for less of a sugar rebound.
• Swap quiches or flans for omelettes – all the flavour, none of the high-calorie pastry.
• Swap high-fat hard cheeses for lower-fat ricotta, feta or reduced fat cream cheese.
• Swap cappuccino for a black Americano.
• Swap ice cream for home-made lollies (made from low-sugar cordials and blueberries or raspberries).
• Swap rice for cauliflower ‘rice’ – grate a portion of uncooked cauliflower and microwave for 1-2 minutes for a lower-calorie substitute that – honestly – doesn’t taste of cauliflower!
• Swap tagliatelle for courgettes sliced into thin ribbons with a potato peeler – boil or steam for 1 minute and serve with your normal pasta sauce.
Food substitutes for when you’re craving something else
• Have something instant to hand in case of a snack attack: if you love sweet things, then no-sugar jelly is ideal at under 10 calories.
• For a savoury craving, a sachet of miso soup or lower-cal cup-a-soup is between 10-40 cals.
• For days when you’re too tired to cook from scratch, a ready-made fresh soup or a small can of beans on a slice of wholemeal from a small loaf come in at under 200 calories.
• Ready meals aren’t fashionable, but the M&S range, Innocent Veg Pots and the Morrison’s NuMe dishes have been highly rated by 5:2 fans.
