start a healthy diet. But starting a healthy diet doesn't mean only eating greens, you should minimize the amount of regular food you take and eat a balanced diet.

Examples of chemical properties are: heat of combustion, clammability and corrosion/oxidation resistance, reactivity with water, PH, and electromotive force. The difference between a physical and chemical property is straightforward until the phase of the material is considered.
                                                                                                                  chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
