Time to shape up for party season? Nutritionist Lily Soutter shows you how to drop a dress size or two...

With festive feasting only weeks away, there’s still time to lose a few pounds. If you start now, you can lose anything from 7-10lbs on our exclusive diet plan, which has been devised by nutritionist Lily Soutter (lilysoutternutrition.com).

“Depending on how much you want to lose, you can do the plan for one or two weeks,” says Lily.

“You can also use it to help negate any festive binges after Christmas. Focus on the way you’re eating as well,” adds Lily. “If you’re rushing around, try to eat your food more slowly. When you eat too fast, you don’t produce the necessary digestive enzymes, so food isn’t digested properly and this leads to bloating. Watch stress levels, too. Stress hormones interfere with digestion, making it more difficult to lose weight. Make time to relax. You’ll feel calmer and your waistline will reap the rewards, too!”

Countdown Guidelines

Eat lean meats, fish, vegetables, Greek yogurt, nuts, seeds, berries and healthy fats like avocado and olive oil.

Avoid caffeine and processed foods.

Drink water and herbal teas, such as lemon and ginger, and peppermint.

Fill half your plat with veg: vegetables are low in calories, but high in nutrients, so will keep you feeling full.

Give food a twist with festive spices like cumin, ginger and nutmeg.

Snacks: 5 walnuts; 1 satsuma; a palm-size of seeds; 1tbsp houmous or 1tbsp guacamole with raw vegetable sticks; or 2tbsp Greek yogurt with 1tbsp mixed seeds and berries.

Want a drink? Choose a clear spirit with fizzy water and fresh lemon/lime.

Avoid socialising on an empty stomach: have a snack beforehand. This will stop you bingeing later.

Write a food diary: a study has shown that it can double weight loss.

Eat mindfully: savour flavours to register that enough is enough.

Walk: even 20-30 mins at lunchtime will boost your metabolism.

Don’t scrimp on sleep: lack of sleep increases appetite.
