This book describes bare facts about how to become healthier and manage your body weight. All information herein are based on research and science. There is no fad diet.

Here are some pointers extracted from the book

Harris Benedict formula:

Calories needs:

Men:

66+(6.23Xweight in lbs) + (12.7X height in inches) – (6.8X age in years) = X calories

Women

665 + (4.35 X weight in lbs) + (4.7 X height in inches) – (4.7 X age in years) = X calories

To eat calories needed for each day, Multiply X calories by the following factors based on how active you are on a daily basis:

No exercise:  X calories times 1.2

Light exercises: (1 to 3 days per week ) X calories times 1.375

Moderate exercises: (3 to 5 days per week) X calories times 1.55

Hard exercises: (6 to 7 days per week) X calories times 1.725

To reduce weight one lb per week, eat 500 calories less or burn 500 calories in exercises per day.

Eating less than 1300 calories per day is unhealthy.

Guidelines to what to eat:

30% of calories from fats (1 gram of fats = 9 calories)

15-20% from proteins (1 gram of proteins = 4 calories)

50-55% from carbohydrates. (1 gram of carbohydrates = 4 calories)

Nutrient needs =

Total calories X nutrient % divide by calories per gram of nutrient.

Nutrient % for proteins = 0.20

Nutrient for carbohydrates = 0.50

Nutrient for fats = 0.30

Examples:

If the diet is fixed for 1800 calories per day

Proteins needs:

1800 X 0.20 divide by 4 = 90 grams of proteins per day

Carbohydrate needs:

1800X 0.50 divide by 4 = 225 grams of carbohydrates per day

Fats needs:

1800 X 0.30 divide by 4 = 60 grams of fat per day

Recommended daily fiber needs:

Male 14-50 years old 38 grams

Male more than 51 years old 30 grams

Female 14 – 18 years old 26 grams

Females 19 -50 years old 25 grams

Females more than 51 years old 21 grams
