Semaglutide is the world's most prescribed therapeutic peptide. A GLP-1 receptor agonist, it reduces appetite by acting on hypothalamic receptors and slows gastric emptying. Approved as Ozempic for T2D and Wegovy for obesity, clinical trials show 15–17% average body weight reduction over 68 weeks.
Nausea (very common during titration)
Vomiting
Diarrhea or constipation
Decreased appetite
Fatigue
Rare: pancreatitis
Avoid if personal/family history of thyroid C-cell tumors
Skipping the titration phase — causes severe nausea that derails the protocol
Not eating enough protein, leading to significant muscle loss
Stopping abruptly without a tapering plan
Expecting results without any dietary adjustments
Insulin and diabetes medications — hypoglycemia risk
Oral medications — slowed gastric emptying can affect absorption timing
Warfarin — monitor INR more closely
Semaglutide works — the 15–17% weight loss numbers are real. But so are the side effects when you skip titration. The critical mistake is losing muscle mass. High protein intake and resistance training are non-negotiable during any GLP-1 protocol.
