More about caloric intake
One study found that as calorie intake increases, there is a corresponding increase in metabolic efficiency that is designed to maintain you around a particular body weight. However, if your caloric intake exceeds your body’s ability to burn up those calories over time, the excess calories are converted into fat and glucose.
The Type of Food You Eat
Protein requires more energy to be broken down, digested, and absorbed, and resting metabolic rate typically goes up after eating protein as much as two to three times more than after eating carbohydrates and fats.
Your Age
The body typically starts to lose muscle after age 30, so everything else being equal—activity level, calorie intake—you’ll gain weight because of this loss of muscle.
Genetics
Some people simply have a naturally more efficient metabolism than others.
Nutritional Status
Metabolism requires the smooth running of many complex physiological processes. When there are nutritional deficiencies, particularly in antioxidant vitamins such as B and C, metabolism can become less efficient.
Water Intake/Hydration
When the body has taken in sufficient water, body temperature can be maintained for optimal metabolism. Dehydration can make the body temperature drop slightly, and with a reduction in temperature, the body will attempt to help raise temperature by storing fat to act as an insulator. So drinking too little water can contribute to an inefficient metabolism and hoarding of fat.
Menopausal Status
Menopause also adds additional hormonal burdens to metabolism and weight loss. During menopause, women become more effective at storing fat and less able to burn fat. After menopause, an enzyme called adipose tissue lipoprotein lipase (AT-LPL) is more active. AT-LPL breaks fat down so that fat cells can absorb it. One study found that the burning ability of fat taken from the buttocks of postmenopausal women was 75% less than in perimenopausal women.
Summary
As you can see, the body is a calorie miser, and there are a number of places that these complicated processes can fail, making it easier for you, especially as a thyroid patient, to gain weight, and making it harder to lose weight. Buy acomplia to lose weight comfortably.
