Stimulant effects: Some people are less sensitive to the effects of sugar and/or caffeine. Also, sugar, in its simple forms (such as that present in pastries or candy) usually causes an energy spike followed by fatigue shortly afterwards. If caffeine is consumed routinely, people can become tolerant of its stimulating properties.
