At-home therapies include injections, capsules, troches, or sprays
Both short-acting and long-acting GLP1RAs reduce body weight, whereas short-acting GLP1RAs have a greater effect on postprandial plasma levels of glucose and long-acting GLP1RAs predominantly lower fasting plasma concentrations of glucose
The reviews analysis confirms that synthetic GLP-1 medications like semaglutide and tirzepatide, originally developed to control blood sugar, offer clinically validated protection against cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic dysfunction-associated steatotic liver disease (MASLD)-related outcomes, including improvements in steatosis and fibrosis-related endpoints
Why it matters: Preserves lean muscle mass and bone density Supports metabolic rate Improves satiety without worsening nausea Supports immune function and recovery Protein targets during active weight loss A practical, evidence-aligned approach: 1.2 to 1.6 grams per kilogram of ideal body weight per day during active weight reduction Or an absolute target of 80 to 120 grams per day, which many people find easier to follow For individuals at risk of sarcopenia, aim for at least 1.3 grams per kilogram per day
