While many factors can affect weight loss, "calories-in calories-out" is the simplest way to lose extra weight. This is essentially consuming fewer calories than you burn off each day.
However, a doctor explained many people overeat calories without realising, and that could cause their weight to plateau.
Weight loss plateaus can be demotivating, as it often seems like your best efforts are going to waste.
Dr Crystal Wyllie at ZAVA explained why these happen and how failing to monitor your diet and calories properly is one of the most common reasons why people do not lose weight.
Look for foods high in fibre and protein
GETTYThe expert said: "One common reason for a weight loss plateau is that your calorie intake has increased.
"The NHS recommends a calorie deficit of around 600 calories per day, so if you’re not sure how many calories you’re eating, this could be preventing you from losing weight.
"Track your calories and be strict with it, as this is the best way to ensure consistent weight loss. What you eat is also very important, and you should be sticking to a healthy, balanced diet."
To create a calorie deficit, slimmers must first work out what their maintenance is for calories, and reduce this number if it is safe and healthy to do so.
Tracking what you eat every day when you do not lose or gain weight is a good indicator of how many calories your body needs to maintain your current weight.
While in a calorie-deficit, it is important to eat healthy foods that will support your body and weight loss in other ways.
The expert recommended eating foods high in fibre and protein, and including plenty of fruits and vegetables in your plan. Dr Wyllie continued: "Fill up on healthy sources of fibre and protein, which keep you fuller for longer.

"Getting enough protein, especially after strength training, as this can help build and maintain muscle.
"Also, limit the amount of high-calorie foods in your diet, especially unhealthy fats and processed foods. It is important to get lots of fruits and vegetables in your diet."
The doctor added that exercise and working on your mentality are both crucial when trying to lose weight.
She concluded: "You’re never stuck in a weight loss plateau, even if it feels like you are. There are always changes you can make to restart your weight loss journey, it just takes time, patience, and consistency."
