Abstract

OBJECTIVE: To examine the effects of dietary protein and obesity classification on energy-restriction-induced changes in weight, body composition, appetite, mood, and cardiovascular and kidney health. RESEARCH METHODS AND PROCEDURES: Forty-six women, ages 28 to 80, BMI 26 to 37 kg/m(2), followed a 12-week 750-kcal/d energy-deficit diet containing higher protein (HP, 30% protein) or normal protein (NP, 18% protein) and were retrospectively subgrouped according to obesity classification [pre-obese (POB), BMI = 26 to 29.9 kg/m(2); obese (OB), BMI = 30 to 37 kg/m(2)). RESULTS: All subjects lost weight, fat mass, and lean body mass (LBM; p < 0.001). With comparable weight loss, LBM losses were less in HP vs. NP (-1.5 +/- 0.3 vs. -2.8 +/- 0.5 kg; p < 0.05) and POB vs. OB (-1.2 +/- 0.3 vs. -2.9 +/- 0.4 kg; p < 0.005). The main effects of protein and obesity on LBM changes were independent and additive; POB-HP lost less LBM vs. OB-NP (p < 0.05). The energy-restriction-induced decline in satiety was less pronounced in HP vs. NP (p < 0.005). Perceived pleasure increased with HP and decreased with NP (p < 0.05). Lipid-lipoprotein profile and blood pressure improved and kidney function minimally changed with energy restriction (p < 0.05), independently of protein intake. DISCUSSION: Consuming a higher-protein diet and accomplishing weight loss before becoming obese help women preserve LBM. Use of a higher-protein diet also improves perceptions of satiety and pleasure during energy restriction.

  • Whether increasing protein intake during weight loss can limit the weight-loss-induced loss of fat-free mass is unclear because of conflicting results reported in the literature.

    “Whether increasing protein intake during weight loss can limit the weight-loss-induced loss of fat-free mass is unclear because of conflicting results reported in the literature (54, 56, 96, 98, 101-108).”

    From Preserving Healthy Muscle during Weight Loss (2017) · cites this paper as [103]

    The Body Weight and Body Composition Changes section reports that higher protein intake preserved more lean body mass during weight loss, and the Discussion describes similar findings in earlier studies. The paper therefore supports the possibility that protein limits fat-free-mass loss, but the cited passages do not support the claim that conflicting results make the question unclear. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • A dietary approach that includes incorporation of high protein content may preserve lean mass better than a dietary approach with lower protein content.

    “A dietary approach that includes incorporation of high protein content may preserve lean mass better than a dietary approach with lower protein content.73”
  • About a quarter of body mass lost during an energy deficit is fat-free mass, and some of that is probably muscle.

    “Typically, ∼25% of body mass lost in an energy deficit can be attributed to fat-free mass (6), some of which is likely muscle (7).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
