- B1.1 keeping healthy- diet, food and metabolic rate
- diet and metabolic rate
- A balanced diet
- you need enough carbohydrates to release energy
- enough protein for growth, cell repair and cell growth
- enough fats to help keep you warm and release energy
- tiny amounts of various vitamins and mineral ions to keep skin, bones, blood and everything else healthy
- varying energy needs
- you need energy to fuel the chemical reactions in the body that keep you alive
- these reactions are called your metabolism and the speed at which they occur your metabolic rate
- muscle needs more energy than fatty tissue
- meaning that those with a higher ratio of muscle to fat will have a higher metabolic rate
- physically bigger people are likely to have a higher metabolic rate than those smaller than them as they require more energy as they have more cells
- men usually have a higher metabolic rate than women
- regular exercise can boost your resting metabolic rate as it builds muscle
- you need energy to fuel the chemical reactions in the body that keep you alive
- when you exercise you need more energy- so your metabolic rate goes up during exercise and stays high afterwards for some time
- so the more active job you have the more energy you require
- A balanced diet
- Factors affecting health
- the effects of eating too much
- too much fat or carbohydrate in your diet can lead to obesity
- the effects of eating too little
- effects can vary depending on what was missing from the diet
- slow growth in children
- fatigue
- poor resistance to infection
- irregular periods in women
- lack of vitamins/minerals can cause deficiency diseases
- people are said to be malnourished when their diet is out of balance
- A lack of exercise
- exercise increases the amount of energy the body uses and decreases the amount of fat. It also boosts metabolic rate.
- so less likely to suffer from health risks associated with obesity
- people can be physically fit but not healthy
- exercise increases the amount of energy the body uses and decreases the amount of fat. It also boosts metabolic rate.
- inherited factors
- some people can inherit factors that effect their metabolic rate
- underactive thyroid gland, which would lower metabolic rate and cause obesity
- can inherit factors that affect their blood cholesterol levels
- high blood cholesterol can lead to coronary heart disease as well as other problems
- the effects of eating too much
- diet and metabolic rate
