AI synopsis

What people are saying

Discussions around this article show a balanced mix of support and questioning, such as posts emphasizing that the study highlights increased fat burning during fasting, and others pointing out that individual responses may vary. The tone varies from scientific references like 'meta-analysis' and 'systematic review' to practical advice such as 'train in the best way possible,' indicating a blend of technical interest and real-world application.

AgreementModerate agreement

Most discussions acknowledge the study's findings that fasted exercise increases fat oxidation, though some posts question or compare it with other methods, indicating moderate support.

InterestModerate interest

Posts demonstrate a curiosity about the research, with users referencing meta-analyses, scientific sources, and discussing practical implications for training and diet.

EngagementModerate engagement

Many community members engage by citing sources, sharing personal opinions, and debating the significance of the findings, reflecting a modest but meaningful level of depth.

ImpactNeutral impact

While some consider the results relevant for fitness routines, others suggest more studies are needed, so perceived impact remains moderate but not transformative.

Abstract in brief

  • The study found that aerobic exercise done in a fasted state leads to greater fat oxidation compared to when the same exercise is performed after eating.
  • The research showed no significant difference in NEFA (fatty acids in blood) levels between fasted and fed states, but blood glucose and insulin levels were higher after exercise in the fed state.
  • Overall, exercising in a fasted state can enhance fat burning, though it does not significantly change certain blood fat levels, glucose, or insulin compared to exercising after eating.]

絶食時の有酸素運動は脂肪燃焼効果が高いことが示されている。これは肝臓のグリコーゲンが枯渇し、脂肪燃焼を抑制するインスリン濃度が低くなることが要因であると考えられている。 #ダイエット https://t.co/9PljcG9iJJ

なんで早朝に有酸素やった方が良いのか調べてみた。絶食状態ではインスリン、肝臓のグリコーゲンのレベルが小さく、エネルギーに脂肪が使われるという理屈。レビューにて脂肪酸化は増加している事が確認された(∩´∀`∩) #筋トレ #ダイエット https://t.co/WgctVXal7G

@DivagoTM @FredLAFernandes Concordo, mas esse foi o só primeiro que peguei no Google, tem outros. Obviamente sua glicose vai estar um pouco mais alta se vc comer um carb antes do treino, mas isso não significa que vc precise comer para treinar.
