TLDR
Modest weight losses of 5 to <10% were associated with significant improvements in CVD risk factors at 1 year, but larger weight losses had greater benefits.Abstract:
OBJECTIVE Overweight and obese individuals are encouraged to lose 5–10% of their body weight to improve cardiovascular disease (CVD) risk, but data supporting this recommendation are limited, particularly for individuals with type 2 diabetes. RESEARCH DESIGN AND METHODS We conducted an observational analysis of participants in the Look AHEAD (Action For Health in Diabetes) study ( n = 5,145, 40.5% male, 37% from ethnic/racial minorities) and examined the association between the magnitude of weight loss and changes in CVD risk factors at 1 year and the odds of meeting predefined criteria for clinically significant improvements in risk factors in individuals with type 2 diabetes. RESULTS The magnitude of weight loss at 1 year was strongly ( P P = 0.79). Compared with weight-stable participants, those who lost 5 to 1c (odds ratio 3.52 [95% CI 2.81–4.40]), a 5-mmHg decrease in diastolic blood pressure (1.48 [1.20–1.82]), a 5-mmHg decrease in systolic blood pressure (1.56 [1.27–1.91]), a 5 mg/dL increase in HDL cholesterol (1.69 [1.37–2.07]), and a 40 mg/dL decrease in triglycerides (2.20 [1.71–2.83]). The odds of clinically significant improvements in most risk factors were even greater in those who lost 10–15% of their body weight. CONCLUSIONS Modest weight losses of 5 toread more

Addressing adult obesity: a psychological framework
TL;DR: In this paper, the authors examined the temporal and contextual dynamics of the weight loss journey by listening to the personal narratives of people who had attended a psychologically-led weight loss intervention, revealing the barriers and enablers to their initial weight loss and maintenance over time.

TL;DR: DBS as a treatment for ED may result in significant objective and psychological benefits and further studies should aim to increase the sample size, standardize follow-up protocol, and standardize the neuropsychiatric tests used to determine psychological and physiological benefits.

Estimation of the Concentration of Low-Density Lipoprotein Cholesterol in Plasma, Without Use of the Preparative Ultracentrifuge
TL;DR: A method for estimating the cholesterol content of the serum low-density lipoprotein fraction (Sf0-20) is presented and comparison of this suggested procedure with the more direct procedure, in which the ultracentrifuge is used, yielded correlation coefficients of .94 to .99.
