Doing OMAD (either lunch or dinner, depends) for weight loss (down from 136kg to 85kg, aim for 75kg, or at least until i get rid of belly and thigh fat) and I drink 500ml of water with: ACV(2tbsp), lemon(2tbsp) and a sprinkle of cinnamon, in one go each morning. Am i actually ruining my OMAD by breaking a fast with this morning combo? ACV and lemon do contain small amount of calories. People here say cinnamon has 0 calories but according to google its 6 calories per tsp. (tho its a cassia cinnamon the bottle is almost over so ill get ceylon one next time). So i assume they add up and get in the way? I still lose a bit of weight but it feels like those extra hours from 6am to 12pm are wasted.
Should i drink this before/after lunch instead?
No you are not ruining anything. Your body will see the glucose increase from the juice and vinegar, convert it to glycogen if you are sendentary or actively use the glucose if you are active and then you will go back to lowering liver glycogen until “Metabolic Switching” occurs. This is the process where you then start converting fat into ketones for energy. Your drink will not significantly impact this process, as you’ve described it.
​
Your energy management systems are continuous processes always adapting to what you are doing. As you eat and drink your body will look for protein and carbohydrates to convert into glucose, as glucose is prioritized for to fuel the body. Fat is a secondary energy source and eating fat doesn’t add to glycogen but instead gets stored directly as fat. It is also important to keep in mind that a calorie is a unit of heat that is produced by the burning of glucose. That same unit of heat can be produced by the burning of fat, but only if long term storage of glucose (glycogen) is low enough in the liver. So calories do not add up, but glycogen and fat does. This is how all fat loss works, CICO does it through limiting energy rich foods, Keto does it through limiting foods that refuel glycogen stores, IF does it through limiting eating windows.
I hope this helps!
It will not ruin your OMAD and it will probably not slow down weight loss, but anything with flavor, even with no calories, will keep you from getting into autophagy if you care about that at all, many don’t unless they have a lot of extra skin. I generally just stick with plain water and black coffee while fasting and it keeps me from feeling hungry.
