Does Apple Cider Vinegar Help with Weight Loss?
Quick Answer
Barely. A few small studies show 2-4 pounds lost over 3 months with daily ACV. That's about 0.5% of body weight. Any effect is likely from acetic acid slowing stomach emptying and reducing appetite slightly. It's not a magic fat burner. Won't compensate for a bad diet.
Key Points
- Studies show only 2-4 pounds over 3 months
- Not a fat burner or metabolism booster
- May slightly reduce appetite
- Won't compensate for poor diet
- Risk of tooth enamel damage if undiluted
Detailed Answer
Apple cider vinegar has an almost cult-like following for weight loss. Let's look at what the research actually says.
The evidence:
• Most cited study (Japan, 2009): 175 obese adults, 12 weeks, 1-2 tablespoons ACV daily. Results: 2-4 pounds lost vs placebo. That's it. • Several smaller studies show similar modest effects • Meta-analyses conclude: statistically significant but clinically marginal
How it might work (theories):
• Acetic acid slows stomach emptying, extending satiety • May slightly blunt blood sugar spikes after meals • Could reduce appetite through various mechanisms • Not a fat burner. No metabolic boost.
The reality check:
2-4 pounds over 3 months is: • About 0.3 pounds per week • Easily within normal weight fluctuation • Less than cutting one soda per day
If ACV helps you eat a bit less, fine. But attributing significant weight loss to vinegar is wishful thinking. The people with dramatic results changed their overall diet.

If you want to try it: 1-2 tablespoons in water before meals. Always dilute. Straight ACV erodes tooth enamel and burns your throat. Results will be minimal regardless of dose.
