Can your body only absorb 30g of protein per meal?

Last verified

No. Your gut absorbs almost all of it, just more slowly for a big dose, and the muscle building response keeps rising with larger doses rather than stopping at a set number. What drives muscle gain is total daily protein, about 1.6 g/kg; splitting it across 3 to 4 meals is a habit, not a rule.

Should you do cardio before or after weights?

Last verified

Do whichever you care about most first. In the same session, lifting before cardio gives a small edge to lower body strength, but order does not change muscle growth, aerobic fitness or fat loss. Separating the two, and not overdoing cardio, matters more than the order.

Consistency or motivation: what actually keeps people training?

Last verified

Motivation is unreliable, and about half of people who intend to be active do not follow through. What predicts sticking with training is turning it into a habit, lowering the friction, and having reasons that are genuinely your own. Consistency is built by design, not summoned by willpower.

Do fat burner supplements work?

Last verified

Mostly no. 'Fat burner' is a marketing label. Only caffeine has evidence for a small effect, and you can get it from coffee; other ingredients have weak or no support. The stimulant load and rare liver injury risk are real. Fat loss comes from a calorie deficit.

Do light weights tone and heavy weights bulk?

Last verified

No. 'Tone' is not a training style, it is visible muscle at lower body fat. Taken close to failure, light and heavy loads build muscle to a similar degree; heavier loads mainly build strength faster. 'Bulk' takes years of overload and usually a surplus, so it does not happen by accident.

Do you really need 10,000 steps a day?

Last verified

10,000 steps is not a universal pass-or-fail target. Cohort studies associate higher step counts with lower mortality, but they cannot predict what adding steps will do for one person. The shape of the association varies by age and study.

Do you need a pre workout supplement?

Last verified

A pre-workout supplement is not a requirement for training. Evidence about one ingredient or one formula does not establish the value or safety of every blend. This article does not recommend replacing a blend with caffeine tablets or copying research doses.

Do you need BCAA supplements?

Last verified

No. BCAAs are 3 of the 9 essential amino acids and cannot maximise muscle building alone; a review calls the anabolic claim 'unwarranted'. They raise synthesis about 22%, far less than whole protein, and add nothing on top of adequate total protein. For almost everyone they are poor value.
