Summary
Maintaining weight loss is challenging. A systematic review found that higher protein intake significantly helps prevent weight regain in overweight or obese individuals, unlike other tested dietary strategies.
Area of Science:
- Nutrition Science
- Obesity Research
- Dietary Interventions
Background:
- Weight regain is common after weight loss interventions.
- Most individuals do not maintain lost weight long-term.
- Dietary strategies are crucial for sustainable weight management.
Purpose of the Study:
- To systematically review and meta-analyze dietary strategies for weight loss maintenance.
- To identify effective nutrient compositions for preventing weight regain.
- To explore potential, understudied weight maintenance strategies.
Main Methods:
- Systematic review and meta-analysis of 21 studies.
- Included 2875 overweight or obese participants.
- Evaluated increased protein, lower glycemic index, green tea, conjugated linoleic acid, and higher fiber intake.
Main Results:
- Higher protein intake significantly prevented weight regain (SMD -0.17, p=0.005).
- No significant effect was found for other dietary strategies analyzed.
- No heterogeneity was detected among studies examining protein intake.
Conclusions:
- Increased protein intake is a key dietary strategy for weight loss maintenance.
- Combining higher protein with other strategies may enhance effects but requires further study.
- Randomized clinical trials are needed to test combined dietary approaches.

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

01:18Reducing Line Loss
370
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

01:28Proteins: Dietary Sources and Requirements
1.6K
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

01:19Mass and Weight
15.1K
Mass and weight are often used interchangeably in everyday conversation. For example, medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...
