Protein
Eating food increases your metabolism for a few hours.
This is called the Thermic Effect of Food (TEF), and it is down to the fact that extra calories need to be digested, absorbed and processed.
Protein causes the largest increase in TEF, as it increases your metabolic rate by 15 to 30 percent.
Carbs only increase your metabolic rate by five to 10 percent, and fats raise it by zero to three percent.
Protein rich food includes lean meat and poultry, fish, eggs, and tofu.
Nuts and seeds, as well as legumes and beans are another great source of protein.
Milk, yoghurt, and cheese will also contribute to your protein intake.
