    Timing of food intake predicts weight loss effectiveness



    Timing of food intake predicts weight loss effectiveness

    Abstract

    Background: There is emerging literature demonstrating a relationship between the timing of feeding and weight regulation in animals. However, whether the timing of food intake influences the success of a weight-loss diet in humans is unknown.

    Objective: To evaluate the role of food timing in weight-loss effectiveness in a sample of 420 individuals who followed a 20-week weight-loss treatment.

    Methods: Participants (49.5% female subjects; age (mean±s.d.): 42±11 years; BMI: 31.4±5.4 kg m−2) were grouped in early eaters and late eaters, according to the timing of the main meal (lunch in this Mediterranean population). 51% of the subjects were early eaters and 49% were late eaters (lunch time before and after 1500 hours, respectively), energy intake and expenditure, appetite hormones, CLOCK genotype, sleep duration and chronotype were studied.

    Results: Late lunch eaters lost less weight and displayed a slower weight-loss rate during the 20 weeks of treatment than early eaters (P=0.002). Surprisingly, energy intake, dietary composition, estimated energy expenditure, appetite hormones and sleep duration was similar between both groups. Nevertheless, late eaters were more evening types, had less energetic breakfasts and skipped breakfast more frequently that early eaters (all; P<0.05). CLOCK rs4580704 single nucleotide polymorphism (SNP) associated with the timing of the main meal (P=0.015) with a higher frequency of minor allele (C) carriers among the late eaters (P=0.041). Neither sleep duration, nor CLOCK SNPs or morning/evening chronotype was independently associated with weight loss (all; P>0.05).

    Conclusions: Eating late may influence the success of weight-loss therapy. Novel therapeutic strategies should incorporate not only the caloric intake and macronutrient distribution—as is classically done—but also the timing of food.

    What does the "late eaters were more evening types" mean?

    Maybe it's because it's 3am, but I tried reading through the study several times and I see absolutely no data showing how they're arriving at that conclusion. I call bull****.

    I see a claim about late lunchers losing less weight (no data).
    Late eaters skip breakfast (so?).
    Some other stuff was associated with meal timing.

    Then there is a table with the initial characteristics of the groups. No results data.

    There is no results data given. If there is then please quote it because I don't have access to see it.

    That isn't the "full text"; you are only reading a brief summary of the paper. If JJ comes back, he'll probably have the full text which would include results tables.

    I guess you would also have to factor in when they worked out for meal timing as well as how spread out the meals were and if the 3 meals were consumed regardless, or if this was just a timing between breakfast and lunch.

    Would love to hear more about this.
