While many people believe that apple cider vinegar and green tea may help you lose weight, the evidence is limited, and taking them together isn't going to enhance the effect. Not only that, but neither remedy is a magic bullet, so you still need to make changes to your diet and activity level to lose the weight. Consult your doctor to discuss a healthy weight-loss diet specific to your needs and your use of any supplements.

Evidence for Weight Loss
A 2012 review study published in the Cochrane Database for Systematic Reviews investigated the data relating to green tea as an aid to weight loss. The authors concluded that while green tea may help you lose weight, its effect is small and not considered statistically significant.
Apple cider vinegar is also used for weight loss, but there's very little evidence that it produces results. A 2013 study published in the Journal of Chiropractic Medicine used apple cider vinegar as part of reduced-calorie diet that included a regimented supplement program. And while the participants lost weight, it's difficult to determine if apple cider vinegar had any influence on the weight loss because the study participants took other supplements that could have been responsible for the effect.
Vinegar, Tea and Your Diet
Apple cider vinegar and green tea are both calorie-free, and they can help you reduce your calorie intake if you serve them in place of higher-calorie foods. Apple cider vinegar adds flavor to food without adding any calories. Use it as a salad dressing, to make pickled vegetables, add flavor to your grain dishes or as the acidic element in your meat marinade.
Drink a cup of plain green tea in the midmorning or midafternoon to help control cravings and unhealthy snacking. The hot beverage takes time to drink, so it may help keep you occupied until your next meal.
Potential Side Effects
There are potential side effects with both apple cider vinegar and green tea. Some people may have a difficult time tolerating the vinegar because it's acidic, and there are concerns that it may affect tooth enamel.
Green tea is considered a safe food, but the tannins may cause nausea, and the caffeine may lead to insomnia. You should also discuss the use of green tea with your doctor due to potential herb-drug interactions such as those with anticoagulants, certain types of pain medication and iron supplements.
The Best Way to Lose Weight
While it's not certain if green tea or apple cider vinegar will help you lose weight, making changes to your caloric equation through diet and exercise will help. Creating a daily 500-calorie deficit by eating less and moving more may help you lose up to 1 pound a week. Eat a diet that's filled with low-calorie, nutrient-rich foods such as fruits, vegetables, whole grains and lean proteins, and aim to move as much as possible by taking the stairs, parking at the far end of the lot or taking three 10-minute walk breaks throughout the day.
