This can happen as early as a few weeks into dieting. Weight gain In addition to the threats of muscle loss and rebound overeating, the body has a third mechanism to maintain weight during a diet: slowing your metabolic rate. It does this by lowering levels of the thyroid hormone T3, which regulates metabolism. Frequent dieting only worsens the effect, making sustainable weight loss a distant possibility. Fat deficiency While low-fat dieting has been in fashion for decades, healthy fats from foods like meat, fish, eggs, avocados, and nuts and seeds are absolutely necessary for health. Fat cushions organs, coats every cell in the body, and is needed for brain function, production of hormones and absorption of vitamins A, D, E and K. Low-fat diets also tend to be high-carb diets, which have been linked to heart disease, cancer and other ills. Protein deficiency Amino acids derived from proteins are used in the body to produce powerful mood-lifting chemicals like serotonin and melatonin are to thank for our sense of well-being and restful sleep. When consuming fewer calories – and amino acids – than are needed, serotonin deficiency can lead to low self-esteem, creating a vicious cycle of dieting in the pursuit of feeling better. Another hallmark of serotonin deficiency, obsessiveness, is linked to the development of eating disorders.
Dieting and healthy eating research- Steve Leske
QUT PHD researcher Stuart Leske is conducting a survey into dieting and healthy eating habits. Interestingly he has found lots of women prepared to be part of it and talk about dieting… but men it seems are reluctant to talk about their eating habits… His on line survey is trying to reveal what influences a persons decision to diet or not to diet. Why some follow calorie chart while others will just increase their veg and fruit intake and not monitor their weight.
