The aim of the present study was to compare the effects of 10 weeks resistance training in combination with either a regular diet (Ex) or a low carbohydrate, ketogenic diet (Lc+Ex) in overweight women on body weight and body composition. 18 untrained women between 20 and 40 years with BMI ≥ 25 kg*m-2 were randomly assigned into the Ex or Lc+Ex group. NIH study finds cutting dietary fat reduces body fat more than cutting carbs. A scale shows pasta/carbs weighed against butter/fat. The researchers studied 19 non-diabetic men and women with obesity in the Metabolic Clinical Research Unit at the NIH Clinical Center in Bethesda, Maryland. About the National Institutes of Health.
Abstract. This study examined the interaction of 2 diets (high protein, reduced carbohydrates vs. low protein, high carbohydrates) with exercise on body composition and blood lipids in women (n = 48, ∼46 y old, BMI = 33 kg/m 2) during weight study was a 4-mo weight loss trial using a 2 × 2 block design (Diet × Exercise). Again, fat oxidation was balanced with fat intake after 7 days of a high-fat diet, although fat oxidation was weakly related to fat intake in the lean subjects but not the obese subjects. This again illustrates that a high-fat diet leads to a positive fat balance, an effect that seems to be more pronounced in obese .
T/F Women in their reproductive years are likely to carry more intra-abdominal fat than are women past menopause. C. subcutaneous fat D. total body fatness E. lean tissue. A very-low-carbohydrate diet may be accompanied by. Hall et al. investigated 19 adults with obesity that selectively restricted dietary carbohydrate versus fat. Cutting carbohydrates increased net fat oxidation while equal calorie fat restriction had no effect. However, cutting fat resulted in more body fat loss than cutting carbohydrates. Mathematical model simulations predicted small long-term differences in body fat.

Get this from a library. Dietary fat and carbohydrate in relation to body fatness in lean and obese men and women. [Michael Gareth Niederpruem]. Subsequently, the individual components of dietary fat and carbohydrate were examined relative to body fatness using a 3-day food diary and a food frequency questionnaire.
Subjects Subjects were 23 lean (±% body fat) men, 23 obese (±% body fat) men, 17 lean (±% body fat) women, and 15 obese (±% body fat) women Cited by: There was no relationship between energy intake and adiposity although leanness and exercise were related (p less than ). When subgroups of lean and obese subjects were compared, the lean subjects derived approximately 29% of their energy from fat and 53% from carbohydrate vs 35% and 46%, respectively, for the obese by: Women and men aged 18–60 years were eligible.
BMI had to be ≤25 kg/m 2 (lean) or ≥30 kg/m 2 (obese), and waist circumference ≤80 cm in women and ≤94 cm in men (lean) or ≥88 cm in women and ≥ cm in men (obese). Exclusion criteria were any cardiovascular, hepatic, renal, or metabolic disease, >3 kg weight change in the last three Cited by: Subsequently, the individual components of dietary fat and carbohydrate were examined relative to body fatness using a 3-day food diary and a food frequency questionnaire.

We investigated 10 male and 9 female subjects who all had obesity with a BMI of (mean±SE) ± kg/m 2 (Table 1).While the men and women had similar body weight and BMI, the women had significantly higher body fat and lower rates of.
However, there were no differences (p > ) in BOD POD-determined body fat percentage, lean body mass, or fat mass between the first and second trial in either groups. Conclusions. In women with PCOS, consumption of a diet lower in CHO resulted in preferential loss of fat mass from metabolically harmful adipose depots, whereas a diet high in CHO appeared to promote repartitioning of lean mass to fat mass.
Keywords: macronutrient. While on the reduced carb diet, they lost about 53 grams of body fat per day. When participants consumed the reduced-fat diet, they had no observed changes in insulin production or fat burning. However, they lost about 89 grams per day of body fat—68% more than when they cut the same number of calories from carbohydrates.
Anthropometric measures of body fatness in men and women were compared. Statistical methods were used to explore the potential difference in the effect of dietary fat on body fatness in men and women.
Stubbs, RJ, Harbron, CG & Prentice, AM () Covert manipulation of the dietary fat to carbohydrate ratio of isoenergetically dense diets: effects on food intake in feeding men ad libitum. International Journal of Obes – The role of high-fat diets in weight gain and obesity has been questioned because of inconsistent reports in the literature concerning the efficacy of ad libitum low-fat diets to reduce body weight.
We conducted a meta-analysis of weight loss occurring on ad libitum low-fat diets in intervention trials, and analysed the relationship between initial body weight and weight loss.
The majority of these successful weight losers consumed a low-fat, high-carbohydrate diet, but the average percentage of energy from carbohydrates had decreased from 56% in to 49% in Meckling KA, O'Sullivan C, Saari D. Comparison of a low-fat diet to a low-carbohydrate diet on weight loss, body composition, and risk factors for diabetes and cardiovascular disease in free-living, overweight men and women.

Excess adiposity can account for approximately 30% to 40% of coronary heart disease,1, 2 many cancers of several types,3 most cases of adult onset diabetes,4 and a substantial proportion of disabling osteoarthritis.5 Whereas genetic factors influence which individuals within a.
This study examined the relationships among body fat, diet composition, energy intake, and exercise in adults. Male (n = ) and female (n = ) adults aged 18–71 y ( ± y, means ± SEM) were hydrostatically weighed to determine body fat (–% of total weight).
Diet and exercise behaviors were determined by use of a questionnaire. Obesity and diabetes. Low-fat diets may favorably influence body weight and adiposity. In the Women’s Health Initiative Dietary Modification Trial (WHI-DM), the low-fat intervention (20% energy as fat, as part of a healthy eating pattern) was associated with significant, small reductions in body weight, total fat mass, and percent body fat as measured by dual x-ray absorptiometry ().
1 I Energy Metabolism and Obesity 7 carbohydrate and fat contents of the diet have been varied over periods ranging from a single meal to a 2-wk period (). A systemic reappraisal of the thermic effect of food was done in lean and obese males randomly fed mixed meals containing 0, 8, 16, 24, and 32 kcal/kg fat-free mass.
Densitometric analysis was used to measure body composition. Preprandial and postprandial energy expenditures were measured by indirect calorimetry.Body composition is very important in determining energy expenditure.
The total body weight represents the sum of body compartments (lean mass and fat mass). In this sense, the estimation of energy expenditure is most difficult in individuals that are in the extremes of body weight (malnourished and obese).The relationships between FFA R a and body composition in men and women are summarized in Table 2.
There was no difference between men and women in the relationship between all measures of adiposity (BMI, FM, percent body fat, total abdominal fat, subcutaneous abdominal fat, and intra‐abdominal fat) and total FFA R a and FFA R a expressed per.
