So I wanted to know what are macro and micro nutrients and what do they have to do with weigh loss?
Great question, Irving! Nutrients are the compounds in food that are vital to human life. Macronutrients are nutrients that are needed in quantities greater than a gram – carbohydrate, protein, fat and water. Micronutrients are nutrients that we need in much smaller milligram or microgram quantities – vitamins and minerals.
It happens that the macronutrients, except water, contain carbon atoms and therefore can provide us energy through our cellular breakdown of these carbon bonds. This energy fuels our nervous system, organs and muscles and can contribute to body fat stores. Water takes part in metabolic reactions and helps cells’ efficiency. The micronutrients have many functions, several of which are to support metabolism – the body’s chemical processes — including the ability to make energy from food. So to get the most from macronutrients, the proper amount of micronutrients are required.
Weight loss occurs when the body burns more calories than it uptakes into cells after digestion and absorption. Too much energy from carbohydrate, fat, and protein combined can lead to weight gain. Insufficient vitamins and minerals compound the problem, but are unlikely to cause weight gain directly.
