The combination approach The most gradual option combines both strategies
The Morton 2018 meta-analysis identified 1.6 g/kg as the plateau for muscle gain in resistance-trained adults [9], and the Helms 2014 evidence-based guidance for adults in a calorie deficit recommends 2.3 to 3.1 g per kg of fat-free mass [10] that is per kg of FFM, not total bodyweight, so for a leaner athlete it lands above the 2.0 g/kg total-BW number
Effects of tirzepatide, a dual GIP and GLP-1 RA, on lipid and metabolite profiles in subjects with type 2 diabetes
An earlier investigation revealed that the combination of fisetin with probiotics ameliorates oxidative stress-related changes in broilers and mitigates erythrocyte fragility induced by heat stress (65)
It is important to note that there is no established direct causative mechanism linking GLP-1 receptor activation to increased gastric acid production or lower esophageal sphincter dysfunction
To contextualize those numbers, the researchers say this is on par with 20 years of aging-related muscle loss in adults 30 and older, who lose an estimated 3% to 5% of muscle mass per decade
