When one is overweight or obese, you are not healthy. High intakes of sugar and saturated
fat leads to weight gain, while your cells are nutritionally starving. This is just as big a health problem as the hundreds of malnourished, hungry children in our country, who do not get enough protein and calories in balanced nutrition each day.
Overnutrition / obesity results in stimulation (activation) of your Immune System, and makes one much more susceptible to inflammatory diseases.
Malnutrition results in suppression of your Immune System, and makes one more susceptible to infection.
