Does eating protein cause weight gain?
Best insight from top research papers
Protein intake, especially in early childhood, has been associated with weight gain and an increased risk of obesity later in life . High protein intake, particularly from dairy sources, has been linked to greater weight gain and BMI in children . However, the specific role of different protein sources in weight gain is still being investigated . Short-term consumption of a high protein diet has been shown to cause weight loss and prevent weight regain . On the other hand, long-term consumption of high-protein diets may have detrimental effects on health, increasing the risk of insulin resistance, diabetes, cardiovascular disease, and chronic kidney disease . Therefore, while protein intake can contribute to weight gain, the effects may vary depending on the source and duration of consumption.

How does the affect of protein intake on personality?4 answersProtein intake can have an effect on personality. In a study on Dubia cockroaches, it was found that high-protein diets led to a bolder personality in males. Another study on Southern field crickets showed that males raised on high-protein diets were more aggressive and active during mating, and also exhibited less behavioral stability. These effects were not observed in females. While there is limited research on the specific relationship between protein intake and personality disorders in humans, some studies suggest that nutrient intake, including protein, may be associated with maladaptive behaviors later in life. Excessive protein intake can also have adverse effects on human health, such as hyperinsulinemia and hyperaminoacidemia. Overall, the effects of protein intake on personality are complex and can vary depending on the species and sex of the individual.
Is there an Increase in dietary protein intake?4 answersThere is evidence of both an increase and a decrease in dietary protein intake in the abstracts provided. In older adults undergoing cardiac surgery, protein intake was found to be substantially lower than the recommended target in the early postoperative period. However, in patients with chronic renal failure (CRF), acidosis did not affect dietary protein intake. Another study found that correcting metabolic acidosis in patients with chronic kidney disease (CKD) can improve dietary protein intake. Additionally, moderate physical activity was shown to increase protein oxidation, suggesting an increase in daily protein needs. Therefore, the effect on dietary protein intake can vary depending on the specific condition or situation.
Is more protein intake beneficial for health?3 answersIncreased protein intake in older adults with a protein intake of at least 0.8 g/kg body weight per day may have a possible beneficial effect on lean body mass and muscle strength when combined with physical exercise. However, the evidence is not sufficient to conclude that increasing protein intake in older adults elicits overall health benefits. The validity and safety of high protein consumption are yet to be fully ascertained, and more scientific evidence is needed. High protein intake in infancy is discouraged due to potential obesity risks later in life, while in children and adolescents, high protein intake may be associated with increased Body Mass Index (BMI). Habitual high-protein intake, without marked carbohydrate and energy restriction, is associated with increased risk for metabolic disorders and cardiovascular diseases. Overall, the relationship between protein intake and health outcomes is complex and influenced by various factors, including age and overall diet composition.
Risk of excessive protein intake on healthy adults?2 answersExcessive protein intake in healthy adults may pose potential risks. High protein consumption, above the recommended dietary allowance (RDA), has been associated with various adverse effects. These include disorders of bone and calcium homeostasis, renal function, liver function, and the progression of coronary artery disease. Long-term low-carbohydrate-high-protein (LCHP) diets have been linked to increased all-cause mortality risk. However, the relationship between all-cause mortality risk and protein intake per se remains inconclusive. It is important to note that protein supplementation is common among physically-active adults, particularly those engaged in strength training. While protein supplementation can contribute to daily protein intake, it is crucial to align eating habits and supplemental intake with strength-training demands through nutritional education. Further research is needed to fully understand the potential risks and benefits of high protein intake in healthy adults.
How does a high protein diet help weight loss?3 answersA high protein diet helps with weight loss by reducing body weight and fat mass while preserving fat-free mass. It increases satiety signaling and reduces food intake by increasing anorexigenic hormone levels and decreasing orexigenic hormone levels. Higher dietary protein also leads to increased diet-induced thermogenesis, blood amino acid concentration, hepatic gluconeogenesis, and ketogenesis, all of which contribute to increased satiety. Protein intake prevents a decrease in fat-free mass, helping to maintain resting energy expenditure despite weight loss. High-protein diets typically induce greater weight loss than low-fat or high-carbohydrate diets during the early phase, but differences between diets are attenuated during the late phase. Adherence to the diet, rather than macronutrient composition, is the major predictor of long-term weight loss success. Higher protein intake has a significant beneficial effect on preventing weight regain.
How does protein effect weight growth in chickens?5 answersProtein has a significant effect on weight growth in chickens. Dietary protein concentrations were found to have a profound impact on broiler performance, with growth performance and nutrient utilization being influenced by protein levels in the diet. It is generally accepted that dietary protein should be balanced in terms of amino acids to support growth and maintenance in birds. Feeding excess protein or amino acids may result in nitrogen emission and environmental issues. The inclusion of processed soy protein in starter diets was found to improve body weight and feed conversion ratio in broilers. Lysine, an essential amino acid, plays a crucial role in protein synthesis and breakdown in skeletal muscle, and an adequate lysine intake is necessary for optimal protein deposition and growth. Heat-related reduction in growth in chickens was associated with decreased nitrogen retention, which could be improved by high protein supplementation.
