The metabolic system will suffer some changes
Our metabolic system has three main purposes, such as turning food into energy that burns calories, the conversion of fuel to building blocks for some nutrients like proteins, carbohydrates and lipids and contributes to the elimination of nitrogenous wastes.
So, your metabolic rate will decrease when you lose some pounds and so are the calories that your organism needs to run.
“A 200-pound person who loses five pounds will have less of a metabolic impact than a 115-pound person who loses five pounds. The severity in which you cut calories and increase exercise will also have an impact. Slower, more gradual changes will have less of a negative impact [on your metabolism],” says Roussell.
