There are so many people who think losing weight is about cutting your daily caloric intake to an extremely low amount. There are so many people on roller-coaster diets, probably too many to count, and most of these people are unsuccessful in their weight loss efforts. These low-calorie diets are not successful because they slow down your metabolism, and this causes your body to enter into “starvation mode.” In starvation mode, the body burns very few calories because it is attempting to store the few calories it is being fed for energy. These diets can cause extreme fatigue and hunger, which is the reason for their lack of success.
Successfully losing weight is a learning process. It involves making healthy food choices, paying attention to portion sizes, and eating small frequent meals throughout the day. The average female adult consumes 1,500 or more calories per day, depending on her activity level. To determine exactly how many calories your body needs daily, calculate your basal metabolic rate (BMR). Basal Metabolic Rate is the energy (measured in calories) expended by the body at rest to maintain normal bodily function. The calculating formula is different for men and women and also changes with age. In order to lose weight, caloric intake should be less than caloric expenditure. The formula for calculating BMR is as follows:
Women: 655 + (4.35 x weight in pounds) + (4.7 x height in inches) – (4.7 x age in years)
Men: 66 + (6.23 x weight in pounds) + (12.7 x height in inches) – (6.8 x age in years)
The activity level of a person must also be considered. To include physical activity, follow this formula:
Multiply the BMR by:
1.2 if sedentary (little or no exercise)
1.375 if you exercise 1-3 days per week
1.55 if you exercise 3-5 days per week
1.725 if you exercise 6-7 days per week
Once you determine your BMR, you can divide the calories into five or six small meals per day, to increase your metabolism. By eating foods high in protein, and decreasing your consumption of fats and complex carbohydrates at each of your five or six meals, your metabolism will become extremely efficient at burning calories.
To maximize the metabolic aspects of your food intake, you should incorporate five or six evenly-portioned meals throughout the day. The first meal should be within one hour of waking up, and each subsequent meal should be spaced two to three hours apart for the remainder of the day. People have to abandon the thought process of three meals a day: breakfast, lunch and dinner. Instead, get into the habit of adopting a nutritional pattern of Meal 1, Meal 2, Meal 3, etc. The reason for this is that traditional meal titles in this country are associated with eating certain patterns such as; breakfast should consist of eggs, bacon and bagels, while dinner should be meat and potatoes.
So how does splitting your daily caloric intake into five or six small meals a day increase metabolism? The human body’s metabolism is like a furnace. If you eat three meals a day, the furnace will begin heating up at the first meal and then die down until lunch, where it will heat up again, cool down until dinner, where it heats up one more time. By eating five or six small meals during the day, the furnace will continue burning throughout the day without the cooling-down periods. This means your metabolism is functioning at an increased rate all day with little fluctuations.
Another way that eating small meals frequently will help contribute to weight loss is by a mechanism called the thermic effect of food. When you eat a meal, your body begins the process of digestion, and this process requires the use of energy. The body actually burns calories while it is digesting food. This is sometimes the reason why people’s body temperature increases when they eat. It makes sense that if the body has to digest more frequent meals throughout the day, then the daily caloric expenditure will be increased.
Another advantage of eating small frequent meals during the day is it will help to balance blood sugar levels and prevent hunger attacks. This is in direct contrast to the low-calorie diets that cause blood sugar levels to experience increases and decreases through the course of the day. Frequent meals also regulate insulin levels, which is necessary for muscle growth and glycogen storage. One of insulin’s roles in the body is to transport glucose and amino acids into the muscle cells, where they can be used for energy and muscle growth.
Adopting this type of lifestyle will require a bit of meal planning and preparation, but it is certainly worth it. Purchasing some Tupperware and a food scale and following this weekly meal plan can help get you started. This meal plan is based on 1,500 calories per day, consisting of 25 grams of Fat, 179 grams of Carbohydrates, and 127 grams of Protein. Once you calculate your BMR, you can adjust serving sizes to meet your individual daily caloric needs
