Are You Making These Dieting Mistakes?

Eating less, but not losing:

Trying to slim down and feeling frustrated?

If you’re giving it your all but the number on the scale still isn’t budging, you may be sabotaging yourself in spite of your best intentions.

Here are a dozen dieting don'ts to help save your weight-loss efforts

You eat fake foods

We admit that prepackaged weight-loss products like shakes and bars are convenient, but they may not be helping you to lose weight in the long run.

"You never feel satisfied after you eat something like that, because it’s just a bunch of processed stuff," says Manuel Villacorta, a registered dietician and spokesperson for the Academy of Nutrition and Dietetics.

There are lots of healthier, more filling options with the same or fewer calories, like a cheese stick or a serving of plain nonfat Greek yogurt with fresh strawberries.

You burn the midnight oil

Sure, you need to log time at the gym, but to lose weight, you also need to log time in your bed.

Skimping on sleep, especially sleeping less than five or six hours a night, can slow your metabolism and cause hormonal changes that hurt your weight-loss efforts.

Being tired may also make you eat more. One recent study found that people who are sleep-deprived consume a whopping 500 extra calories a day

You exercise too much

Yes, you read that right. Exercise is important, but Villacorta maintains that being too focused on it can backfire.

"People think that if they exercise they will magically lose weight, and then they get frustrated," he cautions.

In fact, about 80% of dieting time and energy should be focused on nutrition and 20% on exercise, he says. "If I have a client who’s exercising six times a week, sometimes I’ll cut that in half and have them spend the extra hours shopping and planning meals."

You always choose the salad

Contrary to popular belief, heading for the salad bar may not be your best option.

Salads may not contain enough carbohydrates to help control hunger hormones, according to Villacorta. He suggests a healthy soup and sandwich instead, or tossing a serving of brown rice, lentils, or garbanzo beans into your greens. And beware of high-calorie salad bar additions like blue cheese and candied walnuts.

Add enough of those and "you may as well just have a burger," he says.

You’re a high-calorie health nut

Just because a food is healthy doesn’t mean you can eat a mountain of it.

Switching from white bread to whole wheat bread, eating nuts instead of chips, using olive oil instead of butter —these are all healthy changes. But they aren’t low-calorie substitutions, so portion control is still key

You eat too early

Popular wisdom says not to eat in the evenings, but that may not make sense unless you turn in extra early.

"People eat at 6:00 and stay up until 11:00 or midnight, so their bodies are naturally asking for fuel again," Villacorta says. "I tell people to aim to eat 70% of their calories before dinner and 30% at dinner, but it doesn’t matter how late dinner is." Healthy eating in the evening can prevent a late-night binge on ice cream or cookies.
