The study included 400 individuals aged 19 to 55 years with a mean BMI of 31.83 \u00b1 4.77 (min 25.1 max 51.8). Men comprised 190 subjects and women 210 subjects. The participants were divided into three groups with the following BMI: overweight, class 1 obesity, and obesity class &gt; 1 (class 2 and 3 combined). BMI groups were randomized by gender, the number of trainings per week, training time, intervention length, and intervention type. The online intervention consisted of a 15% energy deficit diet and training. Over the 12-month dietary intervention, overweight subjects reduced average body weight by 16.6%. The group with class 1 obesity reduced body weight by 15.7%. The group with obesity class &gt; 1 reduced mean body weight by 15.4%. The relative weight reduction in the overweight group was significantly greater than in the other obesity groups (p = 0.007). In all groups, the rate of weight loss from month-to-month was statistically significant (p = 0.0001), ranging between 0.6 and 2.6% per month. The results indicate that overweight individuals are likely to experience a percent greater weight loss as a result of a comprehensive lifestyle intervention. Regardless of baseline BMI, the observed weight loss was consistent from month-to-month throughout the 12-month period, which may indicate that the diet, as well as, the training plan were properly tailored to the subjects\u2019 needs and that they were highly motivated to participate in the program throughout its course. Properly conducted lifestyle intervention enables significant weight loss regardless of baseline BMI values.<\/jats:p>","DOI":"10.3390\/nu14163281","type":"journal-article","created":{"date-parts":[[2022,8,11]],"date-time":"2022-08-11T05:43:57Z","timestamp":1660196637000},"page":"3281","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Effectiveness of a 12-Month Online Weight Reduction Program in Cohorts with Different Baseline BMI\u2014A Prospective Cohort Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8190-8659","authenticated-orcid":false,"given":"Jakub","family":"Wo\u017aniak","sequence":"first","affiliation":[{"name":"Department of Dietetics, Institute of Human Nutrition, Warsaw University of Life Sciences (WULS\u2013SGGW), Nowoursynowska 159 C, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarzyna","family":"Garbacz","sequence":"additional","affiliation":[{"name":"Centrum Respo, Chmielna 73, 00-801 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2839-3251","authenticated-orcid":false,"given":"Olga","family":"Wojciechowska","sequence":"additional","affiliation":[{"name":"Centrum Respo, Chmielna 73, 00-801 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142","family":"Wrzosek","sequence":"additional","affiliation":[{"name":"Centrum Respo, Chmielna 73, 00-801 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2554-9388","authenticated-orcid":false,"given":"Dariusz","family":"W\u0142odarek","sequence":"additional","affiliation":[{"name":"Department of Dietetics, Institute of Human Nutrition, Warsaw University of Life Sciences (WULS\u2013SGGW), Nowoursynowska 159 C, 02-776 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,11]]},"reference":[{"key":"ref_1","unstructured":"(2022, May 01).
