The Working Person's Diet Plan

By Dietitian Juliette Kellow BSc RD


Dream job but nightmare figure? Dietitian Juliette Kellow comes to the rescue with a diet plan designed to help working women – and men – lose weight with minimum effort and maximum results…

Whether we work in an office, are constantly on the road or spend days in schools or hospitals, losing weight and working can be more than a challenge.

Working life can have a serious impact on our waistline. Afternoon chocolate runs, business lunches, office biscuits and nearby vending machines can all pile on the pounds.

Demanding bosses, impossible deadlines and an out-of-control workload can leave us feeling stressed and tired. Meaning we’re more likely to skip breakfast and/or lunch and grab high-calorie snack foods to cheer ourselves up and give us a much needed injection of energy.

We can’t just blame what happens between 9am and 5pm for our need to lose weight either.

After a hectic day at work, many of us simply don’t feel like spending time in the kitchen cooking a healthy dinner.

The result: we resort to convenience food or order a takeaway, and relax with a few glasses of wine.

Meanwhile, lots of late nights in the office, or simply being exhausted, can mean we end up ditching all thoughts of exercise and end up slouching on the sofa in front of the TV.

Lack of sleep in itself can have a detrimental effect on weight loss, see Dr Usman's article on how sleep can affect weight loss.

Losing weight when you’re working full time can be too much like hard work. Having to shop for weird and wonderful ingredients, making packed lunches and spending hours in the kitchen when you get home all add to your ‘to do’ list.

Good news then that our diet plan is especially designed to be simple, quick and easy.

You don’t need to spend hours of time on a complicated diet to lose weight, here's plan that’s designed specifically for people who work all day.

All the breakfasts and lunches can either be bought or are ready in a matter of minutes. Plus, every dinner is ready from kitchen to table in less than 15 minutes. But the best bit – this plan should help you lose up to a stone in six weeks!

Here’s why this diet is perfect for you if you work…

√ You can grab breakfast or lunch on the run if you don’t have time to prepare something at home.

√ You won’t need to spend hours preparing healthy meals when you get home from work – all our dinners are ready in less than 15 minutes.

√ You can still enjoy the occasional office treat – whether it’s biscuits, chocolate or a piece of birthday cake.
