If you've been trying to lose weight recently, chances are you're meticulously tracking what you eat and drink in order to ensure you're consuming the right amount of calories.
It may seem simple to make healthier choices when it comes to mealtimes, but what many people overlook is their drinking habits - particularly with regards to coffee.
Often used as a morning pick-me-up, coffee is an integral part of many people's days. But your daily cup could be adding hundreds of extra calories into your intake, as diet expert Michael Mosley has warned.
The Mirror reports if you like to enjoy a latte or a cappuccino in the morning, you could be adding the equivalent of five and a half Mars bars into your weekly calories.
Issuing important advice on his Fast 800 website - which offers members guidance on how to achieve a healthy weight - Dr Mosley said coffee, fruit juice, and alcohol are among the drinks that are the worst for our diets, as they can contain a huge number of calories but won't do anything to make us feel full.
He wrote in his blog: "If you find that you're eating well, exercising and taking care of your healthy lifestyle yet the weight still manages to creep on, there may be a good reason for it.
"Coffees, alcohol and fruit juices should all be factored into your calorie intake when following a weight loss plan. Often forgotten about, your daily latte is probably adding around 1,330 calories per week to your intake, which is around five and a half Mars bars!"
So if you rely on coffee to wake you up in the morning, a simple swap to taking it just black could help you achieve your weight loss goals.
Similarly, Michael also warned that overindulging on alcoholic beverages could be the reason you're struggling to see results on the scales.
He added: "Alcohol is also something to approach with caution as many often forget how high in both calories and carbohydrates it can be. The evidence is clear; alcohol does make you fat. In addition to the impact of calories from alcoholic drinks, the food choices made whilst drinking, and the following day, pose significant, and potentially life-threatening health concerns."
