Weight loss efforts can be derailed by buying convenience food at lunchtime, which is often laden with calories and fat.
A recent study also discovered high street meal deals can contain thirty teaspoons of sugar.
So choosing the right foods to eat for lunch is key to making sure weight loss goals are achieved.
Many people opt for sandwiches, but while carbs are filling, they cause blood sugar levels to crash later in the day.
So instead, choose a meal full of fibre and protein. Fibre takes longer to digest, so will keep your fuller for longer, and protein will keep energy levels high.
When deciding what to eat, aim for 10 grams of fibre and 15 grams of protein minimum.
That is not to say calories should be forgotten, as consuming more calories than you burn will lead to weight gain in the long run.
Use a tracker app to keep an eye on the overall calories consumed each day, and aim for around 400-500 calories for the lunch time meal.
If you are trying to shift belly fat, there is one exercise which could help you lose two inches from your waist.
Running and crunches may not be the answer to a slimmer waistline.
While the gym may be the best starting place to shed inches from your tummy, experts believe interval training is the answer.
Greek researchers recruited participants to perform four hour-long workouts every week.
These routines included 40 minutes of strength training, then for 20 minutes one group ran on treadmills while the other performed body weight exercises.
Eight weeks later, the scientists measured their waistlines and found those who performed body-weight intervals lost two inches of belly fat.
Those who spent time on the treadmill lost less than one inch.
Belly fat is a popular area to target for anyone wanting to lose weight and an expert in body transformation has revealed three gym moves which can bust this problem area.
