Drinking sugar while on a diet can have adverse effects on your health. Excess sugar consumption, especially in sugary drinks, contributes to weight gain by interfering with your body's appetite control system. Liquid calories are not as satisfying as calories from solid foods, making it easier to add more calories to your diet. Sugar-sweetened beverages have also been linked to shorter sleep duration. Additionally, sugar is one of the main causes of tooth decay, and excessive consumption can lead to cavities and more serious infections. High sugar intake is also associated with increased risks of heart disease, type 2 diabetes, cognitive impairment, depression, and certain types of cancer. It is recommended that added sugars comprise less than 10% of a healthy daily diet, which is about 11 teaspoons for a person consuming 1,800 calories daily.

Weight gain and obesity
Sugar is a type of carbohydrate that occurs naturally in many foods, including fruits, vegetables, and milk. However, the primary concern when it comes to sugar consumption is added sugars—those that food manufacturers add to products to enhance flavour and extend shelf life. These added sugars are commonly found in soft drinks, fruit drinks, flavoured yogurts, cereals, cookies, cakes, candy, and most processed foods. Even seemingly unlikely suspects like soups, bread, cured meats, and ketchup contain added sugar.
The excessive consumption of added sugars has been linked to weight gain and obesity. This is because added sugars contribute extra calories to our diet while providing little to no nutritional value. As a result, these empty calories can lead to a higher overall calorie intake, making it more likely that we consume more calories than we burn throughout the day. This caloric surplus is what ultimately leads to weight gain over time.
The impact of added sugars on weight gain is further compounded by their effect on satiety. Unlike whole foods that contain fibre, protein, and healthy fats, which provide a feeling of fullness, added sugars do not offer the same level of satiety. As a result, consuming foods high in added sugars can leave us feeling hungry sooner, leading to increased calorie intake and potential weight gain.
The link between added sugar consumption and weight gain has been supported by research. Studies have found that individuals who obtained less than 20% of their calories from added sugars tended to have lower body weights and lower triglyceride levels, a type of fat in the blood. Additionally, it has been observed that substituting sugar-sweetened beverages with low- or no-calorie alternatives contributed to reduced body weight and a lower percentage of body fat.
To mitigate the risk of weight gain and obesity, it is essential to limit the consumption of added sugars. This can be achieved by reducing the intake of sugary drinks, opting for whole foods, and being mindful of nutrition labels to make informed choices. By reducing added sugar intake and adopting a balanced diet, individuals can effectively manage their weight and maintain a healthier lifestyle.

Heart disease
Consuming too much sugar can have serious implications for heart health. Excess sugar consumption can lead to weight gain, which increases the risk of obesity, a significant contributor to heart disease. Sugar-sweetened beverages are a major source of added sugar in the diet and can be particularly harmful as liquid calories do not satisfy appetite in the same way as solid foods. As a result, it is easy to add more calories to your diet when consuming sugary drinks, which can lead to weight gain and associated health risks.
High amounts of sugar can also overload the liver, leading to a greater accumulation of fat. This can develop into fatty liver disease, a contributor to diabetes, which in turn raises the risk of heart disease. Furthermore, a diet high in sugar can increase ""bad"" LDL cholesterol and decrease "good" HDL cholesterol levels. This imbalance can cause artery-clogging plaque, damaging blood vessels and the heart.
Sugar consumption has also been linked to higher blood pressure, a significant risk factor for heart disease. Regularly consuming large amounts of sugar can lead to insulin resistance, which is associated with an increased risk of heart disease. Additionally, sugar-sweetened beverages can raise blood pressure and stimulate the liver to release more harmful fats into the bloodstream, both of which are known to increase the risk of heart disease.
The effects of excess sugar intake on heart health are well-documented. It is recommended to limit the consumption of added sugars and opt for natural sugars found in fruits and vegetables, which can help regulate blood sugar and reduce the risk of chronic diseases, including heart disease.

Diabetes
While sugar is not the only cause of diabetes, it is one of the factors that can increase your risk of developing the condition. Diabetes occurs when your body cannot effectively regulate blood sugar levels, which can happen when your pancreas stops producing enough insulin, your cells become resistant to insulin, or both. Insulin is a hormone that moves sugar from your bloodstream into your cells. If your body doesn't make enough insulin or you become insulin resistant, you can develop chronically high blood sugar levels, a condition known as hyperglycemia.
Prediabetes is a condition where a person's blood sugar is higher than normal but not yet at diabetic levels. It is closely linked to diet and weight, and consuming high-sugar foods on a daily basis can lead to weight gain and insulin resistance, which are risk factors for developing prediabetes and type 2 diabetes. Excess sugar that is not used for energy is stored as fat, leading to weight gain and further insulin resistance, which can result in type 2 diabetes.
While sugar-sweetened drinks and processed foods have been associated with an increased risk of type 2 diabetes, natural sugars found in fruits and vegetables are less likely to spike your blood sugar due to the presence of fiber, water, and other nutrients. However, it is important to note that even natural juices can contribute to free sugar intake, and combining them with fat, fiber, and protein sources may help prevent blood sugar spikes.
Artificial sweeteners, such as saccharin, aspartame, and sucralose, do not contain sugar and have few calories. However, they have been linked to insulin resistance and type 2 diabetes, although the exact mechanism is not yet fully understood. One theory suggests that artificially sweetened products increase cravings for sweet-tasting foods, leading to increased consumption of sugary foods.
To reduce the adverse effects of high sugar consumption, it is recommended to limit added sugars and focus on a whole-food diet rich in nuts, fruits, vegetables, lean proteins, healthy fats, and whole grains. Drinking coffee without adding sugar may also help reduce the risk of type 2 diabetes. It is important to note that sugar can be a part of a well-balanced diet for people with diabetes, but it is crucial to keep track of sugar consumption and its impact on health.

Dental issues
Sugar is undeniably damaging to teeth in the long run. It leads to plaque build-up, bacteria, and all sorts of dental problems. The frequency with which you consume sugar is what matters. The more often you consume sugar, the more likely it is to turn into acid and become plaque, which can cause dental caries and cavities. The worst types of sugar for your teeth are sticky forms, such as gummy candies or caramel, as they stick to the teeth, giving bacteria more time to eat away at the enamel.
Tooth decay is one of the most common dental problems, second only to the common cold. It can lead to dental caries, which is when acid forms in the mouth and attacks the outside layer of the tooth, creating holes and cavities. The acid is produced by bacteria in the mouth that feed on sugar and carbohydrates. The two destructive bacteria found in the mouth are Streptococcus mutans and Streptococcus sorbrinus, which form dental plaque, a sticky, colourless film that forms on the surface of the teeth. If the plaque is not washed away by saliva or brushing, the mouth becomes more acidic and cavities may form.
To prevent tooth decay, it is recommended to brush your teeth at least twice a day, ideally with a fluoride-containing toothpaste, and to visit the dentist every six months. You can also stimulate saliva flow by chewing sugar-free gum, eating high-fibre fruits and vegetables, and consuming dairy products. Fluoride treatments from a dentist can also help prevent tooth decay. When consuming sugary foods and drinks, it is best to have them with meals rather than as a snack, and to brush your teeth half an hour afterward. Rinsing the mouth with water after consuming sugar can also help balance the pH of the mouth.
It is important to note that sugar-free drinks are not necessarily better for dental health. Many of these drinks are high in acids such as phosphoric, citric, and tartaric acid, which can damage tooth enamel and lead to decay and cavities. This is also true for fruit juices, which are high in natural citric acid. Therefore, it is recommended to drink these beverages through a straw to avoid contact with the teeth.

Calorie deficit
Consuming sugary drinks and food can cause an increase in weight and have a serious impact on heart health. To lose weight, it is recommended to create a calorie deficit, which occurs when you burn more calories than you consume.
The size of a calorie deficit will determine how quickly you lose weight. For example, a 100-calorie deficit will result in slower weight loss than a 500-calorie deficit. However, a small calorie deficit can still be effective over time when combined with healthy habits, such as increased physical activity. The amount of time spent in a calorie deficit depends on your weight loss goals. It is generally considered safe to maintain a calorie deficit until you reach your desired weight, as long as you feel comfortable.
To determine your calorie needs, you can use a calculator that takes into account factors such as your age, sex, height, weight, and exercise habits. Your metabolic rate, or how quickly you burn calories at rest, also plays a role. Hypothyroidism and Cushing's syndrome are conditions that slow metabolism.
To create a calorie deficit, you can consume fewer calories, increase physical activity, or both. It is important to note that a long-term calorie deficit may suppress metabolism and slow down weight loss. Even when in a calorie deficit, it is crucial to make healthy food choices to ensure your body receives the necessary nutrients.
While in a calorie deficit, it is recommended to focus on nutrient-dense foods. Macronutrients such as proteins, fats, and carbohydrates contribute to the caloric value of food. However, when it comes to weight loss, overall calories are more significant than individual macronutrients. It is suggested to cut back on foods with added sugars and minimal nutrition, such as sugar-sweetened beverages, and increase the consumption of whole grains, vegetables, fruits, beans, nuts, and seeds.

Frequently asked questions
Drinking sugar-sweetened beverages can contribute to weight gain and an increased risk of heart disease, type 2 diabetes, and other serious illnesses. It can also cause tooth decay and disrupt your sleep.
According to the NHS, added sugars should make up less than 5% of the energy you get from food and drink each day. That's about 30 grams for anyone aged 11 and older. The American Heart Association recommends a daily intake of no more than 36 grams for men and 25 grams for women.
Water, lower-fat milk, or sugar-free, diet, or no-added-sugar drinks are healthier alternatives to sugary drinks. You can also try diluting no-added-sugar squash with sparkling water or flavouring water with a slice of lemon, lime, or a splash of fruit juice.
Read nutrition labels and limit your consumption of prepackaged and processed foods, which often contain high amounts of added sugar. Eat more whole foods like fresh fruits, vegetables, seeds, and nuts, which provide a steadier supply of energy. Gradually reduce the amount of sugar you add to hot drinks and breakfast cereal until you can cut it out altogether.
