Do Calories in = Calories Out?

Maybe calories in don’t always equal calories out. Why can two people eat the exact same thing and one is thin, while the other struggles to lose weight? A huge piece of the puzzle is the need to lower calorie consumption over time in order maintain weight loss.

I have discovered a great tool that can help manage the battle to drop pounds. Though it is not meant for the general public yet, but as an aid in clinical research, it is certainly a helpful way to strategize weight loss planning. The National Institutes of Health (NIH) created an online “Body Weight Planner” that takes into account current weight, gender, height, age, and activity level in order to predict how body weight will change over time.

“Researchers at the National Institutes of Health have created a mathematical model — and an accompanying online weight simulation tool — of what happens when people of varying weights, diets and exercise habits try to change their weight. The findings challenge the commonly held belief that eating 3,500 fewer calories — or burning them off exercising — will always result in a pound of weight loss.”

Most dietary recommendations don’t take into account lowered metabolism as body weight decreases. A few takeaways from this tool (link below) and accompanying article:

• Lose Weight Slowly! I repeat. Let your metabolism adjust as you change your eating habits.

• Lift Weights: Developing muscle will increase your metabolic rate.

• Make Long-Term Changes: Most people don’t want to drink or eat a bar as a meal for the rest of their lives.

• Eat Real Food: That leaves less room for cupcakes.
