Im single im 22 years old and i wanna ask that if i drink 1 liter of water with 1 inch of cinnamon and 1/4 tesp of fenugreek seeds soaked overnight and drink whole day about a month is its safe for harmones to lose fat is its safe for body.?

Maybe. Unless you have a significant allergic reaction to the components in this concoction it is likely safe. It is unlikely to have any effect on hormones or cause weight loss. The idea that consuming any food/drink/pill will cause weight loss is more myth than fact. Learning why/how you eat and making changes that remain in place over time is the way to manage your weight.

The concoction you described is safe but not effective for weight loss. You need to reduce your intake of food and increase physical activity, to lose weight. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!
