Coito, I thought you were the one arguing that overweight people should be cutting back on their energy intake. How did those empty calories suddenly become "necessary"?
Carbohydrates aren't necessarily "empty" calories. Fruits, vegetables, beans, nuts, seeds, legumes, whole grains, oats....all great stuff.
I'm the one arguing that people have a metabolic rate which indicates how much energy they need. I'm the one arguing that people shouldn't eat more than that if they want to lose weight. Feel free to argue against that, if you like.
Of course people need to eat. And, the body needs energy to survive, and enough food on a daily basis is needed to be healthy. I've not advocated locking fat people in a room and giving them only water until their bodies waste away.
Let's look at real science and not pop culture booksellers trying to tell you about a secret "They" don't want you to know about.
There are plenty of health problems associated with protein only diets. A review on the safety of low-carbohydrate diets notes that Atkins-type diets are at a greater risk for being nutritionally inadequate and raise the issue of potential long-term health effects. Crowe TC. Safety of low-carbohydrate diets. Obesity reviews. 2005;6:235–245.
In a one-year clinical trial reported in Journal of the American Medical Association in 2005, researchers randomly assigned 160 overweight individuals to one of four popular diets. Participants assigned to the Atkins diet lost 2.1 kilograms, while Weight Watchers dieters lost 3.0 kilograms, Zone dieters lost 3.2 kilograms, and dieters following the Ornish program lost 3.3 kilograms. Dansinger ML, Gleason JA, Griffith JL, Selker HP, Schaefer EJ. Comparison of the Atkins, Ornish, Weight Watchers, and Zone diets for weight loss and heart disease risk reduction: a randomized trial. JAMA. 2005 Jan 5;293:43-53.
A review of 107 research studies on various low-carbohydrate, high-protein weight-loss diets concluded that weight loss on these diets is not due to any special effect of restricting carbohydrate; rather, weight loss depended on the extent to which the dieters’ caloric intake fell and how long they continued with their regimens. Bravata DM, Sanders L, Huang J, et al. Efficacy and safety of low-carbohydrate diets: a systematic review. JAMA 2003;289:1837-1850.
Other reports have also found calorie reduction to be the most important factor in weight loss, with no special weight-loss advantage from the restriction of carbohydrates. Kennedy ET, Bowman SA, Spence JT, Freedman M, King J. Popular diets: correlation to health, nutrition, and obesity. J Am Diet Assoc. 2001;101:411-20; Brehm BJ, Seeley RJ, Daniels SR, D’Alessio DA. A randomized trial comparing a very low carbohydrate diet and a calorie-restricted low fat diet on body weight and cardiovascular risk factors in healthy women. J Clin Endocrinol Metab 2003;88:1617-1623.

So why do you think it is that so many people seem to succeed in losing weight by eating the steak and pushing aside the carbs - and no one succeeds by eating the potatoes, bread, and soft drinks, and pushing aside the steak?
