Weight Maintenance


Recently, researchers in Denmark released the results of an interesting study that should bring Feet standing on weighing scaleshope to those of us who are obese or trying to lose weight and keep it off. If you find that your weight seems to ‘yo-yo’, that you lose weight and seem to put it back on straight away, this research may be of interest to you.


At it’s simplest, weight gain can be explained by the energy balance equation – if you consume more calories than you burn you will gain weight with the excess energy stored as body fat. Although obesity is a complex condition with serious social and psychological dimensions, the results of this study on successful weight loss maintenance has provided a clearer understanding of how to sustain weight loss over time.


Study Carried Out

Twenty obese (but healthy) individuals were put on a low calorie diet for an 8 week period and went vegetables and tape measureon to lose on average, 13% of their bodyweight. After the initial weight loss they entered a 52-week weight maintenance protocol consisting of regular support meetings and instruction on lifestyle change.



The main finding in the study was that over the course of the year, levels of GLP-1 and PYY, (hormones that inhibit appetite or make you less hungry) increased compared to levels before weight loss. Levels of ghrelin, which stimulates hunger, had increased immediately after the weight was lost but returned to normal levels over time. This increase in ghrelin level after the weight loss is related to the body thinking it requires more food to maintain its previous weight.



In short, if an overweight person is able to maintain an initial weight loss over time (1 year, in the case of this study), the body will eventually ‘accept’ the new weight and thus not fight against it, as it normally would in a calorie-restricted state.


“The interesting and uplifting news in this study is that if you are able to maintain your weight loss Dumbbells, apple, measuring tapefor a longer period of time, it seems as if you have ‘passed the critical point’ and after this point, it will actually become easier for you to maintain your weight loss than it was immediately after the initial weight loss” – Associate Professor Torekov of the Department of Biomedical Sciences and Novo Nordisk Foundation Center for Basic Metabolic Research.


Many people are able lose weight through a consistent approach involving healthy dietary choices and increased physical activity, however due to the body’s hormonal response, they can find it even more difficult to keep the weight off than it was to lose. If you are in this position and finding it hard, there should be some comfort in the knowledge that it will get easier over time!
