In a national television interview with Barbara Walters in 2014, Oprah Winfrey confessed that not being able to maintain her weight loss was her biggest regret. In that interview, Walters asked Winfrey to finish the sentence, “Before I leave this Earth, I will not be satisfied until I…”

“Until I make peace with the whole weight thing,” Oprah replied. Losing weight is hard; keeping it off is even harder. What is unique about those who succeed? The answer is buried deep in the archives at the Weight Control and Diabetes Research Center in Providence, Rhode Island: The National Weight Control Registry (NWCR), the largest database ever assembled on individuals successful at long-term maintenance of weight loss. Founded in 1994, the NWCR includes more than 10,000 individuals who complete annual questionnaires about their current weight, diet and exercise habits, and behavioral strategies for weight loss maintenance.

Habit #1: Live with Intention

Living with intention eliminates the random approach to weight loss maintenance in favor of the systematic and methodical one that leads to results. The NWCR has shown that, when intention is behind weight loss maintenance, 21 percent of overweight people are successful weight losers. [1]

The longer people keep their weight off, the fewer strategies they need to continue keeping weight off. [2] In other words, weight maintenance gets easier. The longer your clients persist in their intention and behave in accord with that intention, the easier it is for that behavior to “stick” and turn into a habit.

What makes one individual persist at a specific behavior while another individual doesn’t? For starters, the persistent individual has a conscientious personality. In the most recent NWCR study published in 2020, conscientiousness was compared between successful weight losers from the NWCR and non-NWCR weight regainers. [3] The successful weight losers were found to be more conscientious than the weight regainers and scored higher on measures of order, virtue, responsibility, and industriousness. The scientists suggest that being conscientious may help individuals maintain their weight loss by improving adherence to specific behaviors.

In a review of 56 studies that contained 58 health behaviors, researchers at Université Laval in Quebec, Canada and the University of Limburg in The Netherlands found that intention remained the most important predictor of health behavior, explaining 66 percent of the variance. [4] In half of the reviewed studies, perceived behavioral control (believing that you have control over your behavior) significantly added to the prediction.

Habit #2: Control Yourself

Being a successful weight loser requires a lot of self-control, delaying gratification now (e.g., dessert) for the more desirable reward later (e.g., a slimmer waistline, better health, enhanced self-esteem, and happiness).

Compared to typical unsuccessful dieters, successful weight losers are better able to resist temptation, control themselves, and push back against the environment. They restrict certain foods, [5] weigh themselves regularly, [6, 7] and use digital health technology. [8]

One of the key factors of self-control is disinhibition, which literally means not being inhibited. Some inhibition is good, because it prevents people from not giving into temptation and eating whatever and how much they want. High levels of disinhibition are bad, because it leads to risky behavior. Disinhibited eating is a failure to maintain control over eating. The opposite of disinhibited eating is dietary restraint. Several NWCR studies have found that increased disinhibition leads to regaining lost weight. [9, 10, 11, 12, 13] Other studies have found strong relationships between a lack of self-control—impulsivity—and obesity. [14, 15, 16]

Habit #3: Control Calories

Successful weight losers consume fewer daily calories than the general population. Table 1 shows the number of calories the NWCR members consume per day, from the several studies that have reported it, along with the amount of weight they lost at the time they entered the NWCR.

Table 1 – Caloric Intake of Successful Weight Losers

	Calories Per Day	Pounds Lost
	1,381 [17, 18] 1,297 (women) 1,725 (men)	66 63 (women) 78 (men)
	1,306 (women) [19] 1,685 (men)	63 (women) 77 (men)
	1,390 [20]	69
	1,462 [21]	124
	1,400 [22]	62
	1,399 [23]	73
Average Women Men	1,406 1,302 1,705	79 63 78

Successful weight losers consume a low-calorie diet of about 1,400 calories per day, with women consuming about 1,300 and men consuming about 1,700 calories per day. By comparison, the U.S. adult population consumes an average of 2,120 calories per day (women consume about 1,820 calories per day and men consume about 2,480 calories per day). [24, 25]

Successful weight losers control calories several ways, including limiting how often they eat out at restaurants, [26] rarely eating fast food, [27] and limiting how many calories they drink. [28] They are also more likely than normal-weight individuals to have plans to be extremely strict in maintaining their caloric intake, even during times of the year when it’s easy to consume calories, like during holidays. [29]
