It’s tough to lose excess weight and keep it all off. Research demonstrates the vast majority of individuals who lose weight from dieting gain a lot of the weight back within four to five years, and some gain more even. With news like that it may seem that losing a weight and keeping it off is nearly impossible.
So why bother trying? But not everyone who back again lose weight gain it. There are people who have successfully lost a substantial amount of weight – and kept it off. Catenacci recruited 90 adults who fulfilled certain criteria and divided them into three groupings. Members of the successful weight loss maintainer group got lost at least 30 pounds and experienced taken care of that weight reduction for at least one year.
“We were interested in the patterns of physical exercise in these three organizations, but also the power expenditures of these people to understand how the successful weight loss maintainers could actually maintain their weight,” said Catenacci. She continued to explain that one reason weight reduction maintenance is difficult is that the amount of calories that people burn every day is reduced after weight reduction because of the reduction in body size. To accomplish energy balance and prevent weight at a lower life expectancy bodyweight restore, people need to either eat much less and or move more than they did prior to weight reduction in order to compensate for this decrease in calories burned.

Both resting metabolic rate (the pace of which we burn calories at rest) and physical exercise energy expenditure (the amount of calories we burn with motion) go down primarily because of the reduction in body mass. “Basically, you’ve taken off this 50-pound backpack you’re carrying and also you burn less calories from fat with every motion of day every,” she explained. “Furthermore, when you lose weight you need to do lose some muscle mass and some organ mass and your resting metabolic rate is determined by your muscle mass and organ mass”. But, do people who have lost weight suffer yet another drop in metabolism long-term as THE LARGEST Loser study recommended?
According to the latest research published from Catenacci’s dataset, the answer is not clear. “The resting energy costs in the weight loss maintainer group was where it should be predicated on their body structure, their age and their gender,” Ostendorf said. Why the contradicting findings? Ostendorf said that both studies were designed in a different way, with THE LARGEST Loser study pursuing participants over time.
“It’s difficult to compare both studies as the Biggest Loser study experienced a much more powerful study design. They had estimates of the participants’ resting energy expenses before they even lost the weight. Whereas our study was a cross-sectional snapshot, with only 1 data point in time for them,” explained Ostendorf. “I think that part of it was also the amount of weight lost and the way people lost the weight. For ‘The Biggest Loser’ contestants, weight loss was very fast. But there is another bit of good news for people wanting to lose weight and keep it off.
So, how were the formerly overweight people able to maintain their weight reduction without significantly cutting back on their calorie consumption long-term? The research points to the high level of energy expended through physical activity. Quite simply, for weight loss maintenance, definitely not weight loss, physical activity is the main element.
Numerous abstracts and several research papers were offered and published based on information gathered out of this three-group dataset. Many of the findings from this research confirm the importance of high levels of physical activity. “We know diet is important to help you lose weight. But it’s really difficult to reduce your calorie consumption for long term, every day,” Ostendorf says. “So, we have found in Dr. Catenacci’s studies that when people are doing high degrees of physical activity, they are allowed by it to eat a little bit more and it gives them that leeway.
