Take a raw carrot, and hold it to a bare flame. Nothing much happens except some charring and bad smell.
Place some liquid fat (oils) in a shallow dish prepared with a wick. Touch a match to the saturated wick, and observe the heat and light that results. This is one of the oldest kinds of light source known to humankind.
Take some solid fat, meat trimmings or tallow, or left over fat globules from meat dishes. A match might be sufficient to start a flame, or a bit more heat could be needed.
Take some sugar and treat as the solid fat. Preheating might be needed, or start with chemical igniter or acid, but you can end up with a bad smelling carbon sponge.
Mix sugar with potassium nitrate (“saltpeter”, a source of oxygen) and sulfur in the right proportions and you can make a weak form of gun powder.
Place some alcohol of at least 50 percent concentration (also called “100 proof”) in a shallow disk, with or without a wick. A match is enough to start a bright flame.
All these examples, except the carrot, are high energy foods. Consume more than you need and your body weight will increase. Restrict them and you have a chance of losing weight.
