Abstract

Low-protein diets most often induce increased energy intake in an attempt to increase protein intake to meet protein needs with a risk of accumulation as fat of the excess energy intake. In female adult BALB/c mice, a decrease in dietary casein from 20% to 6% and 3% increased energy intake and slightly increased adiposity, and this response was exacerbated with soy proteins with low methionine content. The effect on fat mass was however limited because total energy expenditure increased to the same extent as energy intake. Lean body mass was preserved in all 6% fed mice and reduced only in 3% casein-fed animals. Insulin response to an oral glucose tolerance test was reduced in soy-fed mice and in low-protein-fed mice. Low-protein diets did not affect uncoupling protein 1 and increased fibroblast growth factor 21 (FGF21) in brown adipose tissue and increased FGF21, fatty acid synthase, and cluster of differentiation 36 in the liver. In the hypothalamus, neuropeptide Y was increased and proopiomelanocortin was decreased only in 3% casein-fed mice. In plasma, when protein was decreased, insulin-like growth factor-1 decreased and FGF21 increased and plasma FGF21 was best described by using a combination of dietary protein level, protein-to-carbohydrate ratio, and protein-to-methionine ratio in the diet. In conclusion, reducing dietary protein and protein quality increases energy intake but also energy expenditure resulting in an only slight increase in adiposity. In this process, FGF21 is probably an important signal that responds to a complex combination of protein restriction, protein quality, and carbohydrate content of the diet.

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.
