The thermic effect of food (TEF) is a term that refers to the amount of energy needed by the body to digest, absorb, and metabolize what we eat. If you rather listen than read check out my most recent podcast regarding TEF. TEF is closely related to the macronutrient composition of our diets. It has been shown to have positive effects on our health and can be used to help us lose weight and/or maintain our current weight. Let’s delve deeper into why this phenomenon is important and how it helps us reach our goals.

How Does TEF Work
The thermic effect of food works by increasing the metabolic rate, or the number of calories burned while digesting food. This means that when you eat, your body has to burn more calories than when it’s not eating in order to break down and absorb whatever you ate. This process actually increases your metabolism, which in turn helps you burn more calories throughout the day.

Different Macronutrients = Different Effects
It’s important to note that different macronutrients—fats, carbohydrates, proteins—have different effects on TEF. For example, proteins tend to have the highest thermic effect because they require more energy for digestion than fats or carbohydrates do. In fact, one study showed that protein had a 30% thermogenic response compared with only 3-10% for fats or carbohydrates! So if your goal is to increase your metabolism and burn more calories throughout the day, then focusing on getting enough protein in your diet is key.

The Benefits of Increasing Your Metabolism Through TEF
Increasing your metabolism through TEF has many benefits beyond just burning more calories throughout the day. For one thing, increased metabolism can help boost energy levels so that you feel energized all day long without relying on stimulants like caffeine or sugary drinks. It can also help regulate blood sugar levels so that you don’t experience extreme highs and lows after meals. And lastly, increased metabolism can help improve hormone balance since hormones are integral for regulating your body’s metabolic rate!


In conclusion, understanding how thermic effect of food works is an essential part of maintaining a healthy lifestyle as well as reaching any health-related goals such as losing weight or increasing energy levels. Eating a balanced diet with plenty of high quality proteins will ensure that you get enough nutrients while also increasing your metabolic rate through TEF. Taking advantage of this phenomenon could be a great way for middle aged men looking for improved health and wellbeing!
