How about this one?
A person eating one meal a day. One. It being dinner.A person eating one meal a day. One. It being dinner. Not greasy burgers, not fries dripping in oil...just say, bits of chicken with vegetables and rice. A regular amount. As for the rest of the day, say a sandwich or 4 wheat crackers and an apple.
...
It's a real example. How much less can a person possibly eat?
One meal every OTHER day, apparently. It's obvious: If you're still gaining weight, you're still running an energy surplus. Hey, fuel economy is great! You'll only have to eat every other day! Why would you complain? Food costs money!
Pescado I'm sorry but that's complete bullshit. You cannot just eat nothing or little just because you have a slow metabolism. The body still needs vegetables/fruit, liquids, meat/eggs/nuts/fish/milk/yogurt/cheese (the "/" stands for "or"!) and some suguar and fat (tiny amounts though).
Skipping one category will lead to malnutrition and only slow down your metabolism. That's why crashdiets suck. Your body get's used to low calorie intake, you stop losing weight and if you don't start eating normal again, you'll eventually have a stroke or something else.
The Accurate Way
There are three primary components that make up your body's energy expenditure. Adding these three components together, basal metabolic rate, energy expended during physical activity, and the thermic effect of food is the most accurate way of determining how many calories your body requires each day.
Basal Metabolic Rate (BMR): Most of the body's energy, about 60-70%, goes to supporting the ongoing metabolic work of the body's cells. This includes such activities as heart beat, respiration and maintaining body temperature. To determine your BMR:
For adult males - Multiply the body weight by 10; add double the body weight to this value.
[i.e., for a 150 lb male, 1,500 + (2 x 150)=1,800 cal/day BMR]
For adult females - Multiply body weight by 10; add the body weight to this value.
[i.e., for a 120 lb female, 1,200 + 120=1,320 cal/day BMR]
Energy Expended During Physical Activity: The second component of the equation depends upon your level of physical activity. Physical activity has a profound effect on human energy expenditure and contributes 20-30% to the body's total energy output. One of the most reliable methods in calculating calories burned during physical activity is the Metabolic Energy (MET) Method. This is the method we have used for the Fitness Partner Connection's Activity Calculator for 158 different activities.
Thermic Effect of Food: The last component to calculate has to do with your body's management of food. The increase in energy required to digest food is referred to as the thermic effect of food (TEF) and it's simple to determine:
TEF = total kcals consumed x 10%
[i.e., 2,000 kcals consumed/day x 0.10 = 200 kcals expended for TEF]
The Easy Way
If all of those calculations seem too confusing or tedious, you can roughly estimate your daily calorie requirements using this simple formula:
For sedentary people: Weight x 14 = estimated cal/day
For moderately active people: Weight x 17 = estimated cal/day
For active people: Weight x 20 = estimated cal/day
Note: Moderately Active is defined as 3-4 aerobic sessions per week. Active is defined as 5-7 aerobic sessions per week.
...that is if you want to keep your weight. :roll:
BTW I weigh 50kg...multiplied with 14 = 700cal.
If I'd go with lbs, I'd need a daily intake of 1540cal. Which seems to me more accurate. :lol:
