For decades, not only have we have been focused on quick fixes with a lack of long-term strategies, but we’ve also been facing an oversimplification of the
“eat less and move more” solution to our collective fixation on weight loss. In reality, there are many interrelated factors that regulate and influence
energy balance.
“Calories in vs. calories out” are the layman’s versions of the energy balance equation, which states that if energy intake equals energy expenditure, the person’s weight will remain unchanged.
A person can affect one or both sides of that equation in an effort to impact their weight; consuming more calories than one expends throughout the day results in weight gain, while weight loss is the result of expending more calories than are consumed.
