Its no secret that diet plays a crucial role in achieving and maintaining a healthy weight. However, the relationship between metabolism and nutrient intake is often misunderstood. As a Registered Dietitian, I would like to share some of the science behind metabolism and how choosing nutrient-dense foods can help with weight loss and overall well-being.

Metabolism:
Metabolism is a complex set of chemical reactions that occur within our bodies to convert the food we eat into energy. It's often described as the body's engine, and it's responsible for maintaining essential functions in our body such as breathing, circulating blood, and repairing cells.
The 2 primary components of metabolism:
1. Basal Metabolic Rate (BMR):
This represents the energy your body needs to perform basic functions at rest, such as breathing and maintaining body temperature. BMR accounts for a significant portion of your daily energy expenditure, typically around 60-75%.
2. Thermic Effect of Food (TEF):
TEF refers to the energy expended during digestion, absorption, and metabolism of the nutrients in the food you eat. It accounts for a smaller percentage of your daily energy expenditure, roughly 10% of total daily calories burned.
Your metabolism is influenced by various factors, including genetics, age, sex and body composition. While these factors can't be changed, you do have control over certain aspects of your metabolism through your diet and lifestyle choices.
Nutrient Intake:
Now, let's talk about how nutrient intake impacts your metabolism. Many people believe that simply cutting calories is the key to weight loss. While calorie control is important, the quality of the calories you consume matters just as much, if not more.
Reasons to choose nutrient-dense foods:
1. Satiety:
Nutrient-dense foods are rich in vitamins, minerals, fiber, and other essential nutrients. They keep you fuller for longer, which can help you control your appetite and reduce your overall calorie intake.
2. Energy Balance:
Nutrient-dense foods provide sustained energy and help stabilise your blood sugar levels. This helps prevent energy crashes and cravings, making it easier to stick to a healthy eating plan.
3. Metabolism Support:
Certain nutrients, such as protein, play a role in increasing the thermic effect of food (TEF). Protein-rich foods require more energy to digest and metabolise, contributing to a higher TEF and potentially boosting metabolism.
4. Health Benefits:
Nutrient-dense foods are associated with reduced risk of chronic diseases like heart disease, diabetes, and obesity. A diet rich in nutrients supports overall health.
Examples of Nutrient-Dense Foods
1. Lean protein sources:
Chicken, fish, tofu, beans, chickpeas and lentils.
2. Whole grains:
Quinoa, brown rice, oats, and whole-grain bread.
3. Colourful fruits and vegetables:
Berries, leafy greens, carrots, and sweet potatoes.
4. Healthy fats:
Avocado, nuts, seeds, and olive oil.
5. Dairy or dairy alternatives:
Greek yogurt, low-fat milk, or fortified plant-based options.
6. Hydration:
Water is essential for all metabolic processes.
Your metabolism and nutrient intake are intricately linked, and understanding this connection is key to achieving and maintaining a healthy weight. By choosing nutrient-dense foods, you can support your metabolism, control your appetite, and improve your overall health. Remember that sustainable progress comes from making long-term, balanced dietary choices that nourish your body and support your overall health.
