Energy balance and weight regulation: genetics versus environment

Abstract

The prevalence of obesity is reaching epidemic proportions in many industrialized countries. There is growing evidence that, even if the trigger of this epidemic is found in changes in the environment, genes are interacting with the environment to cause weight gain. Studies of twins reared apart indicate that approximately two-thirds of the variability in BMI is attributed to genetic factors. From prospective studies in Pima Indians we can ascribe 12 % of the variability in BMI to metabolic rate, 5 % to fat oxidation, and another probable 10 % to the level of spontaneous physical activity. These data indicate that at least 40 % of the variability in BMI is related to genetic factors involved in the regulation of food intake and/or volitional activity. This indicates that the most likely successful therapy for obesity may target pathways of the regulation of food intake. Similarly, an environment favouring engagement in physical activity should be promoted.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Strong attraction to food and food cues, slow satiety mechanisms, and high metabolic efficiency were advantageous for survival in a scarce environment.

    “Biological traits like strong attraction to food and food cues, slow satiety mechanisms, and high metabolic efficiency, advantageous for survival in a scarce environment, seem now to be our worst enemies when it comes to resisting an abundance of food”

  • Strong attraction to food and food cues, slow satiety mechanisms, and high metabolic efficiency now make it difficult to resist an abundance of food.

  • The current obesity epidemic is best explained as a mismatch between the modern environment/lifestyle and biological response patterns that evolved in a scarce environment.

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.
