Weight Management & Satiety

Obesity is a multi-factorial and complex health issue. Current guidance for weight management encourages physical activity along with consuming an overall healthy eating pattern which includes whole grains, fruits, vegetables, lean proteins, low-fat and fat-free dairy products. A growing body of research suggests that dietary protein, specifically, can help promote satiety, facilitating weight loss when consumed as part of reduced energy diets.

Several clinical trials have specifically assessed the effects of high-quality protein from eggs on satiety and weight loss. For example:

  • In a study in overweight adults, calorie-restricted diets that included either eggs or a bagel for breakfast were compared; the people who consumed eggs for breakfast lowered their body mass index by 61%, lost 65% more weight, and reported feeling more energetic than those who ate a bagel for breakfast.
  • Men who consumed an egg breakfast versus a bagel breakfast showed that appetite hormones were suppressed following eggs at breakfast, as was energy intake over the course of the day.
  • A study of overweight premenopausal women that evaluated satiety responses to eating a turkey sausage and egg breakfast sandwich versus a low-protein pancake breakfast showed better appetite control and few calories consumed at lunch following the egg-based breakfast.
  • In a 3-month trial among subjects with type 2 diabetes, those who consumed 2 eggs per day for 6 days a week reported less hunger and greater satiety than those who consumed less than 2 eggs per week.

Numerous studies have demonstrated that higher protein meals at breakfast lead to greater feelings of fullness relative to lower protein breakfast meals, which may reduce energy intake and therefore facilitate weight loss (click here for a recent review).  Less understood is the effect of protein consumption at breakfast on the thermic effect of feeding (TEF), a component of total energy expenditure.

Unintended Consequences of Weight Loss: A Researcher Weighs In

It goes without saying that our nation currently faces a serious obesity crisis. Nearly half of the United States has an obesity prevalence greater than 30% and not a single state in the U.S. shows a prevalence less than 20% (Fig. 1). This pervasiveness of obesity has led to a dramatic spike in cardiovascular disease and type II diabetes cases, which has ultimately decreased the quality of life and life expectancy for many Americans (1). One solution to this nationwide problem is weight loss, particularly diet-induced weight loss (2). Even a 5% reduction in body weight is shown to improve fasting blood lipid and glucose concentrations while decreasing the risk of all-cause mortality (3, 4). Indeed, weight loss is beneficial and is needed to combat our on-going battle with obesity. However, the loss of body mass without considering changes in body composition is irresponsible. Though beneficial for metabolic health, weight loss is shown to decrease bone mass (5) which could, in turn, increase the risk of osteoporosis and skeletal fracture.

Does skipping breakfast lead to faster fat loss

Featured article in the Winter 2016 Issue of Nutrition Close-Up; written by Pamela Hernandez, CPT

The National Weight Control Registry (NWCR) reports that 78% of its participants eat breakfast daily.1 With a sample size of over 10,000 individuals who have each lost 30 pounds or more, why is the behavior of eating breakfast still a question as it relates to fat loss and fitness? Even fitness professionals vigorously debate the topic, particularly when it comes to eating before a morning workout.  Continue reading “Does skipping breakfast lead to faster fat loss”

Macro and micronutrient needs of bariatric surgery patients: a review

Featured article in the Winter 2016 Nutrition Close-Up; written by Meagan Moyer, MPH, RDN, LD

Bariatric surgical procedures for the treatment of morbid obesity are becoming increasingly prevalent since their inception in the 1970s. According to a survey by the International Federation for the Surgery of Obesity and Metabolic Diseases (IFSO), 468,609 bariatric procedures were performed in 2013, up 37% from 2011. In 2013, more cases were performed in the United States and Canada (154,276) than any other region of the world. The IFSO predicts that the number of bariatric surgical procedures will continue to rise.1
