You&#8217;ll spend the first 4 weeks gradually increasing your daily dose and reach the full 3 mg dose in week 5. The FDA label sets a clear checkpoint: if you haven&#8217;t lost at least 4% of your starting weight after 16 weeks, liraglutide likely isn&#8217;t working for you and should be stopped. In its main trial, people lost an average of 7.4% of their body weight over 56 weeks.

It mimics a natural gut hormone that tells your brain you&#8217;re full, slows how quickly your stomach empties and helps regulate blood sugar.

It reaches its highest level in the blood about 11 hours after each dose and has a half-life of about 13 hours. That&#8217;s why it needs to be taken every day to keep working, and why missed doses matter more than with weekly medications.<\/span><\/p>\n<h2 id=\"the-liraglutide-timeline-what-to-expect-and-when\"><span style=\"font-weight: 400;\">The liraglutide timeline: what to expect and when<\/span><\/h2>\n<table>\n<thead>\n<tr>\n<th><b>Time on liraglutide<\/b><\/th>\n<th><b>What usually happens<\/b><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span style=\"font-weight: 400;\">Week 1 (0.6 mg)<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Mild appetite changes for some people; little weight change<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Weeks 2 to 4 (1.2 to 2.4 mg)<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Fuller faster, fewer cravings; nausea is most common now<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Week 5 onward (3 mg)<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Full dose reached; appetite control becomes steadier<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Weeks 4 to 12<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Weight loss becomes noticeable on the scale and in how clothes fit<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Week 16<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Checkpoint: at least 4% weight loss means you&#8217;re likely to keep responding<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Months 6 to 12<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Weight loss usually continues but slows, and many people reach a plateau within the first year<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"font-weight: 400;\">Results vary from person to person, and progress is rarely a straight line.

Early response strongly predicts long-term results.

Generic liraglutide has been available since August 2025 and may cost less, and it clears from the body quickly if side effects become a problem.

You reach the full 3 mg dose in week 5. The key milestone is week 16: if you&#8217;ve lost at least 4% of your starting weight, you&#8217;re likely to keep responding. If not, the label recommends stopping and considering another option. In trials, average weight loss was 7.4% at 56 weeks. Take it every day, follow the 3-day restart rule after missed doses, and pair it with protein, activity and good sleep for the best results.<\/span><\/p>\n<p><i><span style=\"font-weight: 400;\">Thinking about liraglutide or another GLP-1 option? <\/span><\/i><a href=\"https:\/\/getheally.com\/patients\/weight-loss-prescription\"><i><span style=\"font-weight: 400;\">Talk to a Heally provider about a weight loss prescription<\/span><\/i><\/a><i><span style=\"font-weight: 400;\">.<\/span><\/i><\/p>\n<h2 id=\"faq\"><span style=\"font-weight: 400;\">FAQ<\/span><\/h2>\n<h3 id=\"how-long-does-it-take-for-liraglutide-to-start-working\"><span style=\"font-weight: 400;\">How long does it take for liraglutide to start working?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Appetite changes often start within the first 1 to 2 weeks.
