I hate these articles. They never touch upon instant foods. Instant foods have no nutritional value and conga lines of ingredience that do nothing but make you fat and unhealthy.
And the nutritional value charts on the sides of the boxes can list vitamin info if supplements are added. Guess what? The supplements will not be processed without other components found in raw foods.
So, people not only gain weight; they become malnutritioned.
That depends on what you mean.
It's really pretty simple.
If you ingest more calories than you burn, those excess calories are converted to fat by your body in preparation for the next famine.
It doesn't really matter where the calories come from.
