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.[i],[ii]

When is a Calorie Not a Calorie?

Gary Taubes—author of Why We Get Fat: and What to Do About It—attempts to make the argument that obesity is the result of a “fat storage defect” which carbohydrates purportedly encourage through the secretion of insulin. Taubes theory hinges on the notion that some calories (carbohydrates) are more fattening than others (protein or fat).

Three reasons why Taubes’ theory fails:

1. Taubes ignores a consistent body of literature that shows “a calorie is a calorie.” At this point there are numerous well done studies that have compared diets of varying levels of protein, carbohydrate and fat that find no statistical difference in weight loss WHEN CALORIES ARE CONTROLLED (kept at the same level for each diet type).

Are Sweet Treats Tipping Your Scale?

What proportion of daily calories would you guess the average American “spends” on “grain-based desserts” (cookies, sweet rolls, pastries, donuts, cakes, pies, cobblers, etc)?

Grain-based desserts are actually the leading source of calories in the average American diet for all people over age two! Yikes, no kidding! They are also a leading source of solid (saturated) fats, sugar and refined grains (three things we eat too much of).[i]

Starvation Mode: Fact or Fiction?

Starvation-mode (or starvation-response) is the popular theory that the body “reacts” to dieting by lowering its metabolic rate in order to preserve itself. According to the theory a dieter could be following a reduced-calorie eating plan—to the letter—and still not lose an ounce. Furthermore, the purported solution is that one needs to eat more in order to lose weight.

The theory is an attempt to explain why people aren’t losing weight although they report (to their weight loss coach, or fellow dieters) that they are indeed following their diet and exercise program.

What are the problems with the theory?
