Your 4 pound loss in 5 days is well worth celebrating...
Well done!!! It is brilliant that has got you through that milestone.
LOL Eating more brings more calories into the equation. Protein is actually a good thing to have more of though...
For the record 1g of protein is 4 calories, 1g of carbohydrate is 4 calories and 1g of fat is 9 calories...
For a lot of people that can all be very interesting - then they ignore it and get on with eating meals that they think of as healthy and adding up the calories of the meal and the day as a whole... If the calorie number hits the magic number then things are good...
Then you have the people that look at how the food is made up from time to time... I certainly don't bother to do it all the time...
Anyway there are all sorts of RDAs which give levels that we would be healthier if we hit with the different macro nutrients... The thing is that the official protein RDA is considered by a lot of experts to be a bit low... I think that it works out at something like 60g for me - but do not follow it so cannot really remember off hand... Lots of people subscribe to the notion that it should be 1g per pound of lean body weight - which for me calculates out at about 100g per day and is what I shoot for normally... Some people say that it should be as high as 1g per pound of actual body weight... Some people even suggest 2g per pound of lean body weight... Generally I like to have it about the 100g or more - but am quite happy for it to go more...
It means that if my calories are right and I am not hungry - but my protein is under 100g - I will tend to eat more to put my protein right even though it may take my calories higher...
I think that it is probably not a good idea to go under your calories too often. You dont want your body to get used to you eating too few calories... Weight loss stalls from time to time and it can be useful then to reduce your calories... If you initially set your calories too low - it removes options regarding how to deal with such things.
