PS: Not all sugars are bad
If stimulating fat loss and improving overall health is our goal then it is imperative to be familiar with sugar and how it affects our metabolism—the good and the bad of it.

Glucose: Our primary energy source
Glucose is the body’s primary source of energy. It fuels our brain, muscles, and vital organs, making it indispensable for overall functioning.
The brain, for one, relies heavily on it for cognitive function. Adequate glucose levels are necessary for concentration, memory, and overall mental performance.
These simple sugars are also crucial for athletes and active individuals as they provide the instant energy needed for intense physical activities. Not to mention, it helps replenish glycogen stores in muscles, aiding recovery and reducing fatigue.
Outside the provision of bodily energy, glucose is involved in various metabolic processes. It helps in the synthesis of adenosine triphosphate or ATP, which is the energy currency of cells. Proper glucose levels also help maintain the balance of hormones like insulin, which regulates blood sugar levels.
Lastly, it is critical for the proper functioning of cells. It’s a key player in cellular respiration, where cells convert glucose and oxygen into energy.
Sugars we’re not supposed to love
Sucrose (aka table sugar) is a disaccharide composed of glucose and fructose. It is often added to processed foods, contributing to added calories without providing essential nutrients. Consuming large amounts of sucrose can lead to rapid spikes in blood sugar levels followed by crashes, which can cause energy fluctuations and increased hunger.
High intake is also associated with the development of insulin resistance, a precursor to type 2 diabetes.
Fructose, a naturally occurring sugar found in fruits, is metabolized in the liver. When consumed in excess, it can overwhelm the organ’s capacity to process it, leading to lipogenesis (fat creation).
High fructose consumption is also linked to non-alcoholic fatty liver disease because the liver converts the excess fructose into fat. Alcohol has the same metabolic effect on the liver.
Excessive fructose and alcohol intake can contribute to the development of metabolic syndromes, which include conditions like high blood pressure, high blood sugar, and abnormal cholesterol levels.
Fructose also does not stimulate insulin secretion or enhance leptin production—hormones that regulate hunger and satiety—leading to overeating and weight gain.
Fun fact: This is also why we can’t stop eating when we’re drunk or recovering from a hangover.
Why we’re not supposed to love sucrose and fructose
They have significant health risks
- Obesity and fat gain: A high intake of added sugars, particularly from sucrose and fructose, is strongly linked to obesity.
- Type 2 diabetes: The regular consumption of added sugars increases the risk of developing the disease due to its effects on insulin sensitivity and blood sugar levels.
- Heart disease: Excessive sugar consumption is associated with increased risk factors for heart disease, including high triglycerides, inflammation, and high blood pressure.
They are deficient in nutrients
High sugar intake often displaces more nutrient-dense foods in the diet, leading to deficiencies in essential vitamins and minerals.
They are addictive
Sugars, particularly in the form of sucrose and fructose, can activate the brain’s reward pathways, leading to cravings and addictive behaviors similar to those seen with certain drugs.
Understanding the different types of sugars and their effects on your health is crucial. Glucose, as a primary energy source, is vital for your body’s functioning, whereas excessive consumption of sucrose and fructose can lead to various health issues, including obesity, type 2 diabetes, and heart disease. By focusing on natural sources of glucose and limiting added sugars, you can maintain better overall health and metabolic function, thus enabling a faster fat loss rate.
