Carbohydrates are macronutrients that provide the body with energy. They are broken down into glucose, which is then absorbed into the bloodstream. When we eat too many carbohydrates, our blood sugar levels rise, and our bodies respond by releasing insulin to stabilise these levels. Excess glucose is stored in the liver and muscles, and any remaining glucose is converted into fat. Excessive carbohydrate consumption can lead to weight gain, high cholesterol, insulin resistance, and an increased risk of metabolic syndrome, type 2 diabetes, heart disease, and obesity. The amount of carbohydrates needed varies from person to person, and it is important to choose complex carbohydrates from whole foods like fruits, vegetables, and whole grains, which are rich in fibre, vitamins, and minerals.

What You'll Learn
Excess carbs are converted to fat
Carbohydrates are one of three macronutrients, along with fats and proteins, that the body breaks down and absorbs for energy. Glucose, or blood sugar, is the primary energy source for the body and brain. Carbohydrates are not inherently unhealthy, and the body needs them to stay healthy and work properly. However, it is important to choose complex carbohydrates over simple carbohydrates.
Simple carbohydrates, or simple carbs, are sugars. They include processed carbohydrates with added sugars, refined carbohydrates, and heavily processed foods. Excessive consumption of simple carbohydrates can lead to a cluster of symptoms known as metabolic syndrome, including increased body fat, insulin resistance, high cholesterol, high blood pressure, high uric acid levels, and blood-clotting problems. In the long term, this can increase the risk of coronary heart disease, hypertension, adult-onset diabetes, obesity, and stroke.
Complex carbohydrates, or complex carbs, are starches and fibres. They are found in whole foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds. These foods are also good sources of fibre, vitamins, minerals, and other health-promoting chemicals. Complex carbohydrates are less likely to spike blood sugar than simple carbohydrates.
When you eat carbohydrates, your digestive system breaks them down into glucose, which enters the bloodstream. The pancreas then releases insulin, which directs the glucose to your cells for energy. If there is extra glucose, your body will store it in your muscles or liver. Once these storage sites are full, your body converts the excess glucose into fat.
Therefore, while not inherently unhealthy, excessive consumption of carbohydrates, especially simple carbohydrates, can lead to weight gain and adverse health effects. It is important to choose complex carbohydrates and maintain a balanced diet to meet your individual needs.

High blood sugar
Carbohydrates are one of the body's primary sources of energy. They are broken down into sugar, which enters the bloodstream. This is known as blood sugar or glucose. When blood sugar levels rise, the pancreas produces insulin to manage the sugar.
However, eating too many carbohydrates can lead to high blood sugar, also known as hyperglycemia. This occurs when the body has more glucose than it needs, and the excess glucose is converted into fat. High blood sugar can put you at risk for diabetes and heart disease. It can also lead to weight gain, as the body stores the excess glucose as fat.
Simple carbohydrates, such as sugar, are quickly digested and can cause spikes in blood sugar levels. They are found in processed and refined foods, as well as sweets, canned fruit, juice, and soda. On the other hand, complex carbohydrates take longer to digest and have less of an immediate impact on blood sugar. They are found in whole grains, fruits, vegetables, legumes, nuts, and seeds. These foods also contain fibre, vitamins, and minerals, which are beneficial to the body.
To maintain healthy blood sugar levels, it is important to limit the consumption of simple carbohydrates and focus on complex carbohydrates. This can be done by choosing whole, minimally processed foods and limiting refined, highly processed foods with added sugars. Additionally, counting carbohydrates can be a useful tool for people with diabetes to manage their blood sugar levels.

Increased risk of diabetes
Carbohydrates are one of the three large energy-yielding nutrients, along with fats and proteins. They are the body's primary source of energy, and the brain relies on carbohydrates to function. Carbohydrates are broken down into glucose, which raises the level of glucose in the blood. The pancreas then releases insulin to help cells absorb this glucose.
Excess carbohydrates can lead to weight gain, high cholesterol, high serum insulin, skin issues, and constipation. Excess sugar in the blood can lead to obesity, and if not burned off through exercise, can cause dyslipidemia and protein deficiency. Excess carbohydrates can also cause the body to retain water, leading to bloating.
Excess carbohydrates are linked to an increased risk of type 2 diabetes, particularly in Asian populations. High-glycaemic-index foods, such as refined cereals, white bread, sugar-sweetened drinks, and pastries, elicit higher glycaemic and insulinaemic responses. This can lead to insulin resistance and type 2 diabetes through beta-cell exhaustion. Beta cells produce insulin to help convert excess glucose into glycogen. If you are diabetic, sugar tends to go very high, and this may lead to serious problems.
The quality of carbohydrates is important, and a diet rich in plant-based carbohydrates can reduce body weight, body fat, and improve insulin function. Carbohydrates from fruits, vegetables, whole grains, legumes, nuts, and seeds are considered 'good carbs', while refined cereals, white bread, sugar-sweetened drinks, and pastries are considered 'bad carbs'. It is recommended that Indians and Asians reduce their carbohydrate intake from 65-75% to 50-55% and increase their protein intake, especially from vegetable sources.
It is important to note that not all carbs are unhealthy, and the amount of carbs consumed is an individual choice based on factors such as BMI, metabolic rate, and physical activity level.

Weight gain
Carbohydrates are macronutrients that provide the body with energy. They are the body's primary source of fuel. When we eat carbs, our digestive system breaks them down into glucose (blood sugar). This glucose is then absorbed into the bloodstream, and the body releases insulin, which directs the glucose to our cells to be used as energy.
Excess carbohydrates, however, can lead to weight gain. When we consume more carbs than our body can use, the extra glucose gets stored in our muscles and liver. Once these storage sites are full, the body converts the remaining glucose into fat. This process can result in weight gain and an increased risk of obesity.
The type of carbohydrates consumed also plays a role in weight management. Simple carbs, which are sugars, can lead to weight gain if consumed in excess. On the other hand, complex carbs, such as starches and fibres found in whole grains, fruits, and vegetables, are less likely to spike blood sugar and contribute to weight gain.
It is important to note that individual factors, such as genetics, body fat percentage, exercise habits, and protein and fat intake, also influence the optimal amount of carbs for each person. Additionally, while reducing carb intake can promote weight loss, it is crucial to consult a healthcare provider before making significant dietary changes.

Digestive issues
Carbohydrates are macronutrients that the body breaks down into glucose (blood sugar) to provide energy. The body prioritises burning carbohydrates over fats and proteins. However, when we eat too many carbohydrates, our body converts the excess glucose into fat. Excess carbohydrates can also cause weight gain, high blood sugar, fatigue, high cholesterol, high serum insulin, skin issues, high triglycerides, and constipation and bloating.
Excessive carbohydrate consumption can lead to metabolic syndrome, also known as insulin-resistance syndrome or syndrome X. Metabolic syndrome is a cluster of symptoms, including increased body fat, insulin resistance, high cholesterol levels, high blood pressure, high uric acid levels, and blood-clotting problems. Long-term, this can lead to coronary heart disease, hypertension, adult-onset diabetes, obesity, and stroke.
Consuming too many carbohydrates can also cause digestive issues. Carbohydrates bind with water in the body, so after eating a carb-rich meal, the body retains excess water, which can make you feel puffy and bloated. Many carbohydrate sources, including carbonated drinks, sugary processed foods, fruits, vegetables, and foods rich in fibre, can generate abdominal gas. The most gas-producing foods are short-chain carbohydrates called FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols).
The optimal amount of carbohydrates varies from person to person, depending on genetics, body fat percentage, exercise habits, and the amount of protein and fat consumed. However, it is essential to choose complex carbohydrates over simple carbohydrates. Complex carbohydrates, such as whole grains, fruits, vegetables, legumes, nuts, and seeds, are nutrient-dense and provide fibre, vitamins, minerals, and other health-promoting chemicals. On the other hand, simple carbohydrates are sugars that can lead to negative side effects when consumed in excess.

Frequently asked questions
Carbohydrates, or carbs, are one of three large energy-yielding nutrients known as macronutrients. The other two are fats and proteins. Carbohydrates are the body's primary source of energy.
Excess carbohydrates are broken down by the digestive system into glucose, a simple form of sugar, and released into the bloodstream, increasing blood sugar levels. In response, the pancreas stops secreting glucagon, the hormone needed for body fat to be burned as energy, and releases insulin, which directs the glucose to the cells for energy. If there is excess glucose, it is stored in the muscles or liver. Once these storage places are maxed out, the body converts the excess glucose into fat.
Excess carbs can lead to weight gain, high blood sugar, fatigue, high cholesterol, high serum insulin, skin issues, high triglycerides, sugar cravings, constipation, bloating, disturbed digestive system, metabolic syndrome, insulin resistance, high blood pressure, high uric acid levels, blood-clotting problems, heart disease, and an increased risk of diabetes and stroke.
Choose complex carbs more often than simple carbs. Focus on nutrient-dense foods with fibre, vitamins, and minerals. Limit foods with added sugars.
