Weight Loss Plateaus: How to reignite your weight loss

A common development after a few weeks of losing weight is that your weight loss stalls, or stops. The scale isn’t budging. This situation—a weight loss plateau—has all kinds of mythology attributed to it.

When you start a diet, you reduce your intake of calories and a big part of that reduction is from carbohydrates. The reduction in carbohydrates leads to the depletion of glycogen (how your body stores sugar) from both your muscles and liver. Each gram of stored glycogen normally holds 3- to 4-grams of water with it.

Can you Become Obese by Eating Just an Extra Bite of Food per Day?

Jane Brody (veteran food columnist for the New York Times) recently reported, “According to researchers is easy to gain weight unwittingly from a very small imbalance in the number of calories consumed over calories used.” Brody continues, “Just 10 extra calories a day is all it takes to raise the body weight of the average person by 20-pounds in 30 years, the authors wrote.

Breakfast Boosts Metabolism – Fact or Fiction?

Have you ever wondered if breakfast really boosts your metabolism—as you so often hear?

ANSWER: False

As a health educator I can give you a lot of good reasons to eat breakfast—the notion that it boosts your metabolism, however, isn't one of them!

Digesting food does “cost” an average of 10% of a meal's calories to digest and assimilate it (see TEF, below). However, is that really a “boost” in metabolism? No, it is not. When you read these claims that "breakfast boosts your metabolism" it's implied that eating breakfast has an affect on your underlying metabolic rate. That is simply not the case. The only metabolic affect of eating breakfast is the commensurate TEF, just as for any meal.

Protein Mythology... get the Facts!

[Part-2: The Dukan Diet]

One common tactic in fad-diet books is to attach various notions (false claims, baseless theories, etc.) to a valid piece of scientific information.

A consistent thread of this sort you will find among high-protein/low-carb diet books has to do with the fact that protein takes more calories to process than other calorie-containing macronutrients (carbohydrates, fat, and alcohol).
