Appetite suppression and fat oxidation were higher on a high-protein diet without than with carbohydrates exchanged for fat. Energy expenditure was not affected by the carbohydrate content of a high-protein diet.

Diet-Induced Weight Loss Is Associated with Decreases in Plasma Serum Amyloid A and C-Reactive Protein Independent of Dietary Macronutrient Composition in Obese Subjects
The very low-carbohydrate dieters had a significantly greater decrease in LogSAA, but their weight loss also was significantly greater. In this study, the decreases in inflammatory markers correlated significantly with weight loss. Also, change in LogSAA correlated with change in insulin resistance. Thus, in otherwise healthy, obese women, weight loss was associated with significant decreases in both SAA and CRP. These effects were proportional to the amount of weight lost but independent of dietary macronutrient composition.
Premenopausal Women Following a Low-carbohydrate/High-protein Diet Experience Greater Weight Loss and Less Hunger Compared to a High-carbohydrate/Low-fat diet
This study examined the effects of a low-carbohydrate/high-protein (LC/HP) diet versus a high-carbohydrate/low-fat (HC/LF) diet on scores of eating restraint and hunger. Percent change in body weight was significant for both groups over time, although relative weight loss was greater in the LC/HP group (14.8%) compared to the HC/LF (4.3%) group at wk 6. The LC/HP group had a significant decrease in hunger score from baseline to wk 6, while the HC/LF group did not. While women in both diet groups experienced weight loss, the LC/HP group had a greater percent change in body weight over time with lower scores for hunger compared to the HC/LF group. A LC/HP diet may facilitate weight loss without extreme restraint or hunger.
Efficacy and Safety of a High Protein, Low Carbohydrate Diet for Weight Loss in Severely Obese Adolescents
Significant reduction in BMI-Z-score was achieved in both groups during intervention, and was significantly greater for the HPLC (high protein low carbohydrate) group. Both groups maintained significant BMI-Z reduction at follow-up; changes were not significantly different between groups. The HPLC diet is a safe and effective option for medically supervised weight loss in severely obese adolescents.
Comparison of High-Fat and High-Protein Diets With a High-Carbohydrate Diet in Insulin-Resistant Obese Women
In routine practice a reduced-carbohydrate, higher protein diet may be the most appropriate overall approach to reducing the risk of cardiovascular disease and type 2 diabetes. To achieve similar benefits on a HC diet, it may be necessary to increase fibre-rich wholegrains, legumes, vegetables and fruits, and to reduce saturated fatty acids to a greater extent than appears to be achieved by implementing current guidelines.
Comparative Effects of Low-Carbohydrate High-Protein Versus Low-Fat Diets on the Kidney
In healthy obese individuals, a low-carbohydrate high-protein weight-loss diet over 2 yearswas not associated with noticeably harmful effects on GFR, albuminuria, or fluid and electrolyte balance compared with a low-fat diet.
Effect of a High-Protein, Low-Carbohydrate Diet on Blood Glucose Control in People With Type 2 Diabetes
A LoBAG (low-biologically-available-glucose) diet ingested for 5 weeks dramatically reduced the circulating glucose concentration in people with untreated type 2 diabetes. Potentially, this could be a patient-empowering way to ameliorate hyperglycemia without pharmacological intervention.
Urinary Ketones Reflect Serum Ketone Concentration But Do Not Relate to Weight Loss in Overweight Premenopausal Women Following a Low-carbohydrate/High-protein Diet
Thirteen overweight premenopausal women aged 32 to 45 years consumed <20 g carbohydrate/day with liberal intakes of protein and fat for 2 weeks; thereafter, carbohydrate intake increased 5 g/week for 10 weeks. Serum-hydroxybutyrate was correlated with presence of urinary ketones, but no relationship was found between weekly weight change and serum ketone production. Urinary ketones are detected in premenopausal women complying with a low-carbohydrate/high-protein diet and are associated with serum ketone concentration.
Short-Term Effects of Severe Dietary Carbohydrate-Restriction Advice in Type 2 Diabetes–a Randomized Controlled Trial
Weight loss and high-density lipoprotein (HDL) ratio improved was greater in the low-carbohydrate (LC) group over low fat group. Carbohydrate restriction was an effective method of achieving short-term weight loss compared with standard advice.
Systematic review and meta-analysis of different dietary approaches to the management of type 2 diabetes
Low-carbohydrate are as effective as low-GI, Mediterranean, and highproteindiets in improving various markers of cardiovascular risk in people with diabetes and should be considered in the overall strategy of diabetes management.
