Wake up, check weight

not drinking any water during the day is bad for your kidneys OP. also its probably your scale isnt accurate or you changed clothes

best weight loss diet:
meal 1,2,3: one teaspoon of olive oil, 33.33 grams protein from egg whites, one bowl of broccoli. potassium supplement, multivitamin, calcium and vitamin d supplements. 10 glasses of water a day, with sunlight for vitamin d. 20 minutes of exercise per day on the diet, primarily lifting weights to prevent muscle loss

>vitamin d supplements
No.
Just go outside. You only need about 15 minutes of sunlight a week to get all of your Vitamin D requirements. Taking more from supplements doesn't do anything.

Supplements are generally good and all, but you shouldn't bother with things you can or do easily get enough of because your body just expels the excess.

And the 10 glasses of water a day includes water in food you consume. You shouldn't just drink lots of water because water is something you can have too much of.

And air is a mixture of gases

Correct.
