Scientists Reveal Two Key Nutrients for Faster Weight Loss

The best performers, out of the total sample, who regenerated 41%, were observed to have lost 12.9% of their body weight by eating sensible portions based on dietary prescriptions that provided a route to weight management and a route to weight maintenance.

Successful Dietary Strategies

An evaluation of a 25-month trial of self-directed dietary education and weight loss indicated that among the efficacious weight losers, the more beneficial were those that contained higher amounts of protein and fiber. They also loved the customization and, thus, the flexibility in implementing plans that dieters would not ditch half way.

After one year, 41% of participants reported successful weight loss, with an average reduction of 12.9% of their body weight, while the rest of the sample group, on average, had lost slightly more than 2% of their initial body weight, as stated in a paper that has been done on the subject and published in Obesity Science and Practice.

The Individualized Diet Improvement Program

The dieters studied were enrolled in the Individualized Diet Improvement Program (iDip), which employs computerized graphics applications and 8 weekly structured training sessions focusing on nutrient composition with the aim of educating the dieters on the improvement of nutrient knowledge for the development of their own safe and efficacious weight reduction program, according to Manabu T. Nakamura, a professor of nutrition at the University of Illinois at Urbana-Champaign and the director of the University of Illinois at Urbana-Champaign and the leader of the research.

“When it comes to dieting programs, people should be given the freedom to choose with an added touch of professional advice that will enhance their gains in weight loss,” Nakamura explained. “Thus, a realistic and individual gradual shift towards sustainable dietary change is needed to maintain our weight and, if desired, to lose weight. The iDip approach allows enough flexibility to test different iterations, and the knowledge and skills gained during the weight loss phase are best to turn towards once weight loss is achieved.

The objectives of the iDip plan include the intake of more protein and fiber in the diet as well as the intake of less than 1500 calories per day.

Data Visualization Tools and Dietary Guidelines

In light of the dietary guidelines developed by the Institutes of Medicine, the iDip team innovated a diagrammatic, two-dimensional, quantitative data map that shows foods in terms of protein and fiber per calorie, which has an ideal range for each meal type. From the foods they continued to take, they developed their personal diet plan, increasing amounts per day of protein to approximately 80 grams and fiber to almost 20 grams.

Correlations Between Protein, Fiber Intake, and Weight Loss

WLAN scales show the key dieters and their eating habits. They were able to record the participants’ eating habits and their weights and reverse the correlation of fiber and protein consumed with weight loss percentages.

“The data imply that one has to consume more protein and fiber and fewer calories to achieve the best possible safety and effectiveness of weight loss diets,” noted the first author, Mindy H. Lee, the then graduate student and registered dietitian-nutritionist for the iDip program. During weight loss, mostly when on some weight loss drugs, Nakamura argued that the retention of lean mass is very key.

The Role of Protein in Preserving Lean Mass

Nakamura said the preservation of lean mass is very important while losing weight, especially when using weight-loss drugs.

“In the recent past, the use of lipotropic injections, which are considered to be weight loss products, has been on the rise,” Nakamura said. “However, when these medications are taken when food intake is severely restricted, they precipitate serious side effects of muscle and bone loss, provided that protein intake is not adequately boosted during weight loss. ”

Out of them, nine were males and 13 were females. 22 enrollees were finally able to complete their program. Of the lot, the largest number of dieters were between the ages of 30 and 64. Participants noted that they had previously engaged in weight-loss efforts two times or more. They also had other diseases: 54 % had a high cholesterol level, 50% had skeletal disorders, and 36 % had hypertension and /or sleep apnea. Furthermore, the dieters reported medical conditions including diabetes, non-alcoholic fatty liver disease, cancer and depression, based on the study conducted.

Impact of Depression on Weight Loss

Previous diagnoses of depression showed the seven dieters who said they had been diagnosed, let alone the total, lost considerably less weight—practically 2.4% of their initial weight more than patients without depression, who lost 8.39% of their initial weight. The team also discovered that weight loss did not alter between patients with or without the other comorbidities, between young and old participants or between male and female patients.

The evaluation of the body composition showed that fat loss while dieting was equal to an average of 7.5% of lean body mass, which is equal to 1 kilogram of fat mass at the six-month interval. For those who lost more than 5% of their starting weight, it was found that 78% of the weight that was shed was from fat.

Long-Term Fat and Weight Loss Results

In specific, the total fat mass of the participants decreased averagely from 42.6 kilograms at the start of the program to 35.7 kilograms at, for instance, 15 months. Similarly, as the dieters’ waist circumference decreased to about seven centimeters at six months and reached nine centimeters at an overall fifteen months, the team identified.

In monitoring protein and fiber intakes by dieters , the team discovered both protein and fiber intakes were significantly related to weight loss at 3 months and also at 12 months.

Nakamura explained: “This shows that if participants were able to adhere to changes within the first three months, they continued to lose weight in subsequent months. On the other hand, if the participant’s struggle was to make desirable changes in the first three months, they mostly did not make further changes in the remaining months.

The team hypothesized that this could also have been linked with the improved early outcome evidenced by some of the diets, which may have had a positive influence on dieters’ compliance with their program.
