Those who embark on a weight loss journey often focus their attention on cutting unhealthy foods out of their diet.
But while eliminating calorific, ultra-processed foods is a good start, this should not be a slimmer's only strategy.
Taking to TikTok, dietician Jo Sebastian (@itsjosebastian) stressed the importance of looking at what you can add to your diet rather than what you should take away.
She said: "If you're here to lose weight, here's one of the biggest weight loss mistakes: not eating enough protein.
Protein is 'one of the most satisfying macronutrients'

"But most of the time on a weight loss journey, we're so focused on cutting out all the foods - don't eat this, don't eat that - that we forget to add in nutrients that are actually going to make things more satisfying."
Jo encouraged slimmers to stock up on protein and fibre sources, placing particular emphasis on protein.
She described it as "one of the most satisfying macronutrients" - the three being proteins, fats and carbohydrates. It is also important for building muscle and supporting hormones.
The dietician said: "Adding more protein to your meals and snacks and spreading it out throughout the day can help you feel more satisfied and help you reach your goals."
She concluded by advising slimmers to focus more on what they can add to their meals rather than what they should restrict, explaining that this outlook makes for more "sustainable" results long-term.
Eating a protein-rich diet is hailed as an effective strategy by weight loss gurus and slimmers alike.
An article entitled 'Clinical Evidence and Mechanisms of High-Protein Diet-Induced Weight Loss', published in the National Library of Medicine, verified this.
Experts said: "Several clinical trials have found that consuming more protein than the recommended dietary allowance not only reduces body weight but also enhances body composition by decreasing fat mass while preserving fat-free mass in both low-calorie and standard-calorie diets.
"The mechanism underlying high protein diet-induced weight loss involves an increase in satiety and energy expenditure."

However, trials that span more than one year are required to examine the effects and safety of high-protein diets properly.
As recommended by the experts at Harvard Medical School, the best high-protein sources are beans, peas and lentils, nuts and seeds, lean meats, fish, dairy products and soy products.
To "burn fat and improve the metabolism", slimmers were told how much protein they should eat per day.
As well as incorporating more protein into their diets, slimmers are advised to up their vegetable intake.
According to a doctor, one "delicious way to cut calories" is by adding a particular vegetable to every meal.
