Protein Prescription for Aging Muscles: Why Leucine Matters More After 60

The Muscle-Building Supplements That ACTUALLY Work (YouTube link ) Muscle and bone health aren’t just parallel concerns—they’re mutually reinforcing systems. Protecting one helps preserve the other. That’s why interventions like resistance training, adequate protein (especially leucine), vitamin D, and mobility-focused exercise are central to healthy aging strategies. Leucine: A Key to Combating Age-Related Muscle Loss  Maintaining muscle mass is difficult as we age due to anabolic resistance , a reduced ability of aging muscle to respond to protein and exercise (Breen & Phillips, 2011). This resistance is a major factor in sarcopenia ( age-related muscle loss ). To counter this, older adults need a higher protein intake ( 1.2–2.0 g/kg of body weight/day , compared to 0.8 g/kg for younger adults) and should aim for 25–40 grams of high-quality protein per meal (Deutz et al., 2014; Moore et al., 2015). Leucine , a branched-chain amino acid, is the primary trigger for muscle pr...

Vegetarians: How to Get Enough Protein?

As a vegetarian, should you be concerned about protein deficiency?  The answer is probably NO for at least two reasons: People are actually more likely to suffer from protein excess than protein deficiency If you know what sources of plant protein to take  How Much Protein Do You Really Need? In [1], Dr. Michael Greger provides the following guidelines: Adults require no more than 0.8 or 0.9 grams of protein per healthy kilogram of body weight per day, which is about  your ideal weight in pounds multiplied by four and then divided by ten . So, someone whose ideal weight is 100 pounds may require up to 40 grams of protein a day. On average, they probably only need about 30 daily grams of protein, which is 0.66 grams per kilogram, but we round it up to 0.8 or 0.9 grams because everyone’s different and we want to capture most of the bell curve. Adverse Effects of Protein Excess People are actually more likely to suffer from protein excess than pr...
