Research indicates that there is no single best way to lose weight. Some people lose pounds by counting calories, while others do well when they go low-carb, paleo, or vegetarian. At RDX Sports, we believe “Why” remains the most significant catalyst in this whole equation. In fact, this is what we’ll try to figure out in this detailed blog. Of course, you’ll also get an actual, functional 7-day weight loss diet plan and something more. Something that’ll help you stick to it and make the most of it.

Figuring Out the Science behind the Success of a Diet Plan for Weight Loss

A study in the Journal of the American Medical Association found that no one program is substantially better than the others. Instead, success was related to the level of motivation people had to stick with their chosen program.

“Most people know how to lose weight. You have to eat less or change your diet and burn more calories,” says Sofia Rydin-Gray, director of behavioral health at Duke Diet and Fitness Center in Durham, North Carolina. 

She adds, “But since we are human beings, it is not that simple. There are psychological variables. We have self-limiting feelings, thoughts, and beliefs that make it more difficult. And that’s where motivation comes into play.”

Obesity researchers have been working hard to identify the factors that help some people stick with their desire to lose weight while others give up. 

There is the National Weight Control Registry (NWCR), a registry that lists more than 10,000 people throughout the country who shed off at least 30 pounds and kept the new weight off for more than a year. 

Graham Thomas, a co-investigator at the register and Associate Professor of Psychiatry at Brown Albert School of Medicine, believes this record has some clues to it. 

Thomas notes that very few people on the registry said their motivation for losing weight was to look better. Instead, the motives tend to run deeper; many said they were motivated by specific health issues.

Based on that record, here are some science-based strategies to help you identify and stick to your weight loss goals as you begin your journey to eating better and being healthier.

  • Find Your “Why” before You Find a Diet Meal Plan

The stronger the connection between your weight loss and your values, the more successful you’re likely to be, says Gary D. Foster, a clinical psychologist. He serves as chief scientific officer at WW (formerly known as Weight Watchers). 

He recommends taking a hard look at why you want to lose weight. “The more specific the answer, the better,” he says. He adds, “If the answer is that you want to be healthier, ask yourself why you want to be healthier.” 

If the answer is that you want to look better, Foster suggests you dig a little deeper. Will you feel more comfortable in social situations? Will it boost your confidence? “What you’re looking for is getting to that core value that can serve as the motivational anchor.”

  • Keep Your Weight Loss Goals Real

Setting impossible goals can lead to a sense of frustration that may make you give up. 

According to an NIH-backed study, in a studio of women enrolled in a weight-loss center, those who set the most ambitious weight-loss goals were also the most likely to drop out. 

Experts say that one or two pounds a week are a reasonable goal for most. They also recommend being realistic about your diet because if you set too many restrictions, you’ll end up overindulging. 

  • Set Intermediate Goals

Research shows that a goal is more likely to be achieved when broken down into a series of manageable steps. The confidence boost you experience every time you accomplish an intermediate goal will help you stay motivated. 

So, instead of focusing on losing a certain number of pounds per week, consider goals like “I’m not going to eat after 7 pm,” “I’ll start walking five days a week,” or “I’m going to eat fruits five days a week.”

  • Must Have a Backup Plan

Most people on the National Weight Control Registry (NWCR) had a few falls before achieving long-term success. Try to remember that everyone slips up. It is critical not to beat yourself up about it too much. 

“If you tell yourself ‘I’m a failure, I’m never going to lose weight,’ you’re going to give up and then eat to feel better,” says Rydin-Gray. Instead, you need to figure out what you learned from the situation and then do something deliberate immediately to get back on track.
