New Diet Book ‘always hungry? ” Updated end debate calories
#Cosmoread: A new book is a long-standing belief that when it comes to weight loss or diet, calories are what counts challenges.
Dr. David Ludwig book? “Always hungry” (Grand Central Life & Style, 2016), he argues that the types of foods you eat – not just the number of calories in those foods – the number of calories burned affects.
“Our mantra is’ Forget the calories. Focus on the quality of what you eat, and your body will do the rest, ” Ludwig, New Balance Foundation Obesity Prevention Center at Children’s Hospital Boston, said the director.
Indeed, the shift from quantity to quality and the few experts who have studied how the diet affects weight is gaining ground in the middle for diet.
It comes to weight loss, the question about low-carbohydrate diet high carbohydrate diet or a low fat diet higher in fat than those who are better than you really are not, but of high quality Overall the quality is low or diet, said Dr. Dariush Mozaffarian, dean of the Tufts University Friedman School of Nutrition Science and Policy.
However, the majority of scientists is still focusing on total calories, Mozaffarian told Live Science.
Dr. Louis Aronne, at Weill Cornell Medical College in New York, director of the comprehensive weight control or diet center and book author (Houghton Mifflin Harcourt, 2016) “Your Biology dietary changes”, Mozaffarian agreed with.
The last advice for weight loss or diet advice in new book “a huge change”, Aronne said.
Which came first: overeating or weight?
“Always hungry”, Ludwig argues that the problem is overeating weight, but the process of gaining weight leads to overeating actually makes is that instead.
What happens when you eat highly processed carbohydrates to explain, Ludwig points. First, there is a spike in the hormone insulin. That suck insulin calories and causes fat cells to hold on, Ludwig told Live Science. (“It’s Endocrinology 101,” he said.) In an optimal metabolic environment, those calories from fat cells the body needs energy to be released next time, but in an overweight person, the fat cells are trapped in the storage mode, and they do not release those calories, he said. So, when the body needs energy, the brain signals of hunger, he said, and thus, the person overeats not diet.
Insulin levels change, you reduce the amount of processed carbohydrates in your diet, with plenty of fat and protein and carbs need to change them, Ludwig said. When you do this, insulin levels drop and fat cells are released back into their extra calories the body, he said. When this happens, decreases appetite, metabolism begins to accelerate, and weight loss or diet can occur without your body fight back, he said.
Insulin and Beyond
Not all experts agree that insulin weight and maintaining weight or diet is the main driving factor.
Insulin is part of it, but there are many factors at play, Mozaffarian said. For example, our intestinal bacteria from the foods we eat can affect the liver and the brain, he said.
Indeed, some of the foods on the brain and body weight effects are a growing area of interest for researchers.
For example, there is evidence that the process of gaining weight or not diet, loss in the brain is important for nerves called the hypothalamus that regulate metabolism, Aronne told Live Science.
And other hormones are also at play.
The satiety hormone leptin (feeling of fullness) signals, plays an important role in weight control or diet, Dr. Amy Rothberg, an assistant at the University of Michigan Health System Metabolism, Endocrinology and Diabetes professor of internal medicine in the division of.
People with higher levels of body fat have higher amounts of leptin, Rothberg told Live Science. Meaning they indicated that these people have found they did not pick up enough calories can develop leptin resistance, she said.
(Ludwig mentioned that he thinks leptin is important as well, but only after it has taken its toll spikes insulin comes into play.)
Carbohydrate calories vs.
Rothberg said he thinks it’s all still comes down to calories. But the evidence shows that certain foods help weight loss than others to be better, she said.
Indeed, not all experts believe that calories do not count the calories of the agreement, there will be different effects on different body types.
“I have proof that when it comes to body weight, calories are what matters am persuaded by,” Marion Nestle, nutrition and food studies at New York University professor said. “If you want to lose weight, eat less then works all the time.”
“With that said, overall health depends on where the calories come from and certain foods – for example, with sugar – and encourage people to eat more,” Nestle told Live Science.
And finally, Ludwig said, he does not completely dismiss the calories. In the short term, a person can lose weight and limit your calories, Ludwig told Live Science. The problem is that over the long term, slow the metabolism of the body’s hunger and to fight back through the emotions, in part begins, he said.
It seems that the mathematics behind the storage and burning calories is wrong, it’s not how it is ultimately not the body weight is controlled, he said. The book’s premise is that by correcting these underlying mechanisms, a “reset” the body weight set point can (in other words, the weight of your body is always to hover around that time) with.
All experts agreed that weight maintenance is difficult for many, if not most people can be.
Body fat mass is hard-wired to protect us, Rothberg said.
A person loses weight, there is a “strong counter-regulatory response” in the body in order to gain weight, Rothberg told Live Science. This reaction certainly hunger hormone secretion and metabolism slows down, including driving, she said.
