Research: Cutting calories could lengthen life
Cutting the number of calories you eat daily could extend your life. Eating 300-500 fewer calories per day has scales down the aging process by lowering a thyroid hormone triiodothyronine, which has been shown in previous studies to slow metabolism and the aging of tissues. While persons in both the calorie-restriction group and exercise group lost weight and body fat, only those in the calorie-reduction group saw their triiodothyronine levels decrease. "There is plenty of evidence the calorie restriction can reduce your risks for many common diseases," said Edward Weiss.

Maintaining weight loss: Brain, hormones, metabolism and fat want those pounds back
Most people can lose weight. But few can maintain their new weight for long. Researchers are now tackling that problem, and what they're finding out is troubling. The body is designed to undermine weight loss: once a body has been fatter, it wants to get back to the weight that it used to be. Physiology is changed in two ways: The body needs fewer calories to maintain itself, but its craving for food is more intense. "We have a huge number of diet books and diet programs, and if you do them, you can lose weight. The big problem is keeping it off... 5%-10% of people are successful at keeping weight off on a long-term basis," said Paul MacLean.

Research: Hunger hormone works by making food look more appealing
A hormone produced in the gut urge people to eat more by making food seem more appealing, research discloses, proving the wisdom behind the advice that people should never go food shopping when they are hungry. "It's something that people knew but this explains it. Ghrelin is a gut signal, it's the way the gut communicates with the brain to make you hungry. And how it does that is by increasing the rewarding nature of food cues, by making ... food thoughts ... more attractive to you. And therefore increasing the probability that you will eat," said Dr. Alain Dagher.

How to Control Your Most Powerful Weight Loss Hormone
If you are overweight there is a good chance you are generating way too much insulin, "the fat storing hormone," after meals. The more insulin enters bloodstream after a meal, the more fat tissue will be stored after that meal. One trick to keep insulin levels low is to eat a small amount of "monounsaturated fat" before meals. It is found in many foods, but we recommend eating about 1 teaspoon of natural peanut butter with every meal. When you eat this type of unsaturated fat it slows up the absorption of carbohydrates, which has the same effect as eating fiber.

High-Protein, Low-Fat, and Low-Carb diets suppress hunger
Many diets are based on changing the proportion of carbs, proteins, and fats one ingests as a method to promote weight loss. A new study could shed light on mechanisms by which different diets boost weight loss. This study examined how different nutrient types suppress ghrelin, the only known appetite-stimulating hormone. "We found that when fat is consumed, levels of ghrelin remain relatively high, which could in turn stimulate hunger. Protein consumption resulted in the greatest suppression of ghrelin... consumption of carbohydrates resulted in a strong ghrelin suppression initially, although subsequent ghrelin levels rebounded well above baseline."

Exercising after meals boosts hormones that suppress appetite
Exercising after meals can help promote weight loss by boosting hormones that suppress appetite. Active people feel less hungry after exercise, and this carries through to their next meal. Even when their meals were bigger, sporty people gained fewer calories overall because they burned off more. --- Volunteers were fed the same breakfast. An hour later, half of them worked out. And when given the chance to eat afterwards, people who had exercised tended to eat more, however, when the amount of energy burned during exercise was taken into account, the sporty people took in fewer calories overall.
