Science-based diet tips that really work

(HealthDay)—There’s no shortage of good diet advice, but the following tips have scientific research to support them.

For starters, take the advice to never go shopping hungry one step further by eating a piece of fruit before you go. Researchers found this encouraged people to buy 25 percent more produce.

It’s always a good idea to limit snacking while watching TV, so never eat right out of the bag. This is even more important advice to heed when you’re caught up in the action of a program: The more distracting the show or movie, the less aware you are of how much you’re eating.

Most people know that it takes diet and exercise to lose weight. But a three-part approach may be even better. Staying in contact with a diet coach, just by phone, helped dieters in one study maintain a 10 percent weight loss.

Another study found that first learning maintenance skills for healthy eating—before any attempt to diet—led to greater weight loss success.

Here’s how to get smarter about weight loss before dieting:

• Learn about energy balance: calories in versus calories out.
• Learn about healthy portion sizes and how to be more active.
• Get in the habit of weighing yourself daily to monitor fluctuations and recognize regain.
• Make small but frequent lifestyle tweaks and practice more good-for-you habits.
• Develop a plan to deal with diet disruptions like restaurant buffets and holiday parties.

You might also do better on a diet that takes into account your unique needs. For instance, decide whether you would benefit more from a weight loss program that helps you work through an unhealthy relationship with food and improves a negative body image. Or one that emphasizes environmental changes, showing you how to improve the quality of your diet and boost physical fitness and your motivation level.
