Nutrition is the food we eat, necessary for health and growth. There is a famous saying “We are what we eat”.
Fitness is 70% diet and 30% exercise. This means that eating healthy is more important than doing thousands of sit-ups. Remember, you can’t out-train a bad diet.
ROLES OF NUTRITION TO FITNESS
1. Nutrition provides the body with the energy it requires to function
The Total metabolic rate is the total amount of energy the body spends to function. It comprises of:
- Basal metabolic rate. The energy the body requires to carry out basic functions such as breathing, digestion, blood circulation, regulating hormone levels, growing and repairing cells. This amount to about 60 to 70 per cent of calories burns in a day.
- The energy required to do all kinds of physical activity. This amounts to 20 per cent of daily energy use.
- Thermic effect of food – is the energy you use to eat, digest and metabolize food. It amounts to about 5 to 10 per cent of daily energy use.
2. It helps our muscles grow
Adequate nutrition is essential for building muscles. Your nutrition should correlate with your fitness goal. For example, if you plan to lose weight, you can substitute animal protein such as chicken and fish for whole grains, legumes, vegetables and fruits while if you are planning on bulking – bodybuilding, the opposite is true. The quality of the diet improves our fitness.
3. It helps boost our immune system
The right nutrition helps boost our immune system, preventing us from falling sick.
Protein is part of the body’s defence mechanism. It’s necessary to eat the right balance your diet. Examples of proteins include seafood, lean meat, poultry, eggs, beans and peas, soy products and unsalted nuts and seeds.
Fruits are essential to provide us with vitamins with numerous health benefits.
4. For treating diseases
Obesity is a serious public health concern because it predisposes to other diseases such as high blood pressure, heart diseases, liver diseases, diabetes mellitus and other health-related issues such as constipation, ulcers etc.
5. For Increasing bone strength
As women grow they reach the stage of menopause, many changes occur. Some hormones such as estrogen and progesterone become less produced.
Lack of estrogen causes a decrease in bone density, the bones become weaker – this is known as osteoporosis. It becomes more difficult to exercise, joint aches and pain.
Nutrition must be greatly depended upon to achieve fitness at this stage. Studies have shown that nutrition has a greater impact on bone strength than exercise.
NUTRITION AND WEIGHT LOSS
When talking about weight loss, nutrition comes to mind first way above fitness
Healthy Weight Loss = 80% Nutrition + 20% Exercise
This is Terri Edwards’s story. She is a licensed Food for Life Instructor.
“Around 1995, I was twenty-eight years old and somewhat overweight. I began an excruciating exercise program of power walking/jogging 35-40 miles per week, plus an additional 20 miles on the bike. Did I lose the weight? Sure. Think of the calories I was burning! I thought I was eating healthier too, but learned later that what I thought was healthy, really wasn’t.
I was even featured in Shape magazine’s “Success Stories” in July 1998.
A few years later, I started gaining a little bit of weight back, even though I was wearing myself out with exercise. I came across an article that said as we age, our metabolism slows down due to natural muscle mass decreases, so we need to increase our calorie burning exercise. If we don’t, we gain 10 lbs every few years, even though we are still exercising. I remember thinking, “WHAT?!” I was exercising myself to death to keep the weight off, and now I’m going to need to continually increase the intensity and distance, just to keep from gaining? That discouragement was the beginning of the end of my exercise-warrior days.”
As we age our body’s metabolism response to exercise decreases.
It becomes more difficult to burn calories and lose weight by just mere exercising alone.
It’s important to note that not only diet and nutrition play a role in Weight loss.
Weight gain depends on a complex of factors which include metabolism, genetics, ageing, diet, hormone regulation, and the impact of the environment on your lifestyle, including sleep, physical activity and stress.
Dietrine Carb Blocker can you help reduce the amount of carb absorbed thereby reducing weight gain.
A balanced diet is a diet that contains an adequate proportion of carbohydrate (carbs), protein, fats, vitamins and mineral and water. A Balanced diet is an optimal diet the body needs to get the nutrients it need to function it best.
About 50 to 60 per cent of your total daily calories should come from carbohydrate, about 12 to 20 per cent from proteins and about 30 per cent from fat.
It is recommended you eat 5 times per day.
HOW TO CALCULATE THE NUMBER OF CALORIES YOU GET FROM FOOD
A Calorie/kilocalorie is the energy needed to raise the temperature of 1 kilogram of water through 1°C. It is often used to measure the energy value of foods.
1 g of Carbohydrate and Protein gives 4 Calories each while 1 g of Fat gives 9 Calories.
You should be able to calculate the calories you get from diet. You can use a food calorie calculator to do this.
The exact number of calories might vary. This is an approximate measure.

knowing the calories you consume is very important if you want to reach a fitness goal or lose weight.
Calculate your total metabolic rate using the TDEE calculator and subtract it from the total number of calories consumed using the calories calculator.
For weight loss, the number of calories you consume must be less than the energy you spend. The opposite is true if you want to gain muscles.
Accumulation of extra calories is stored by your body as fat. 3500 extra calories equal to one pound of fat. Fats are the body’s way of saving energy.
It’s recommended that an average woman eat about 2000 calories per day to maintain, and 1500 calories to lose one pound of weight per week. An average man needs 2500 calories to maintain, and 2000 to lose one pound of weight per week. This value varies depending on age, height, weight, activity levels, metabolic rate. You can calculate the number of calories you need.
Nutrition is a very broad and important aspect of fitness. You must pay attention to it.
