Resumen
Terminar habitualmente las comidas, conocido como limpieza del plato, no parece tener un impacto significativo en el índice de masa corporal. Este metaanálisis no encontró una relación general entre limpiar el plato y el aumento de peso.
Área de la Ciencia:
- Ciencia de la Nutrición
- Ciencia Conductual
- Salud Pública
Sus antecedentes:
- Los entornos alimentarios modernos promueven porciones más grandes, lo que podría aumentar el consumo total de alimentos.
- Se hipotetiza que la práctica de 'limpieza del plato' (terminar porciones enteras) contribuye al aumento de peso.
- La investigación existente sobre el vínculo entre la limpieza del plato y el índice de masa corporal (IMC) muestra resultados inconsistentes.
Objetivo del estudio:
- Realizar un metaanálisis que examine la correlación entre las tendencias de limpieza del plato y el índice de masa corporal.
- Sintetizar los hallazgos de múltiples estudios para determinar la relación general.
Principales métodos:
- Se realizó un metaanálisis de datos de 22 muestras independientes.
- Se utilizó análisis estadístico, incluida la meta-regresión, para evaluar el efecto combinado e identificar posibles moderadores.
Principales resultados:
- El efecto general combinado (r = 0.04) no indicó una relación significativa entre la limpieza del plato y el IMC.
- La meta-regresión reveló que la proporción de mujeres en la muestra del estudio y la medida específica de autoinforme utilizada moderaron el efecto.
- Puede existir una pequeña asociación positiva en hombres y al usar la Escala de Tendencia a Limpiar el Plato.
Conclusiones:
- La limpieza habitual del plato no se asocia generalmente con un mayor peso corporal.
- La falta de una asociación clara justifica una mayor investigación sobre los factores que contribuyen.
- Los sesgos de autoinforme pueden influir en los hallazgos, pero la ausencia de un vínculo sólido es notable.

01:12Reduced Mass Coordinates: Isolated Two-body Problem
2.4K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

01:09Directing Effect of Substituents: meta-Directing Groups
5.8K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

1.7K
Mass spectrometry is an important technique for the identification of pure compounds. However, it has some limitations for the analysis of complex mixtures, often due to excessive fragmentation making the spectrum too complicated to decipher. Mass spectrometry can be combined with suitable separation methods in sequence, forming hyphenated methods, which are useful in the analysis of complex mixtures.

Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

01:07Body Temperature
1.4K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...
