Gordz, as a male you should be eating up to 2000 calories per day, depending on your level of activity. I don't even know how you can stand eating only 400 calories per day!!
At the end of the day, we are all here doing our own thing, but i am only saying this because i'm concerned for your overall health, and i don't want you to develop an eating disorder. So please don't take offence, this is just advice, in my opinion, and you don't have to take it.
yes, court is right about eating more calories, however, those calories need to come from an appropriate
i'm sorry to say this, but it is about what you put in your body as much as how much you put in. You need a good mix of protein, complex carbs fruit and veg. For example, to maintain muscle mass you need to eat approximately 2grams per kilo of body weight. You should be eating LOTS of veggies (some people reccomend 5cups per day) you should be eating two serves of fruit, and low fat dairy for calcium and other added benefits. If you exercise, you should be eating a serve of carbs to fuel you through that work out, as well as after would with a good protein source (like a protein shake) to help carry the protein to your muscles. You need GOOD fats, like in nuts, avocados and uncooked olive oil. you need an extreme lack of trans fats (found in hydorgenised foods like margerine) you need to have amino acids and vitamins!
saving your calories for alcohol is not a good idea. There is approximately 6 calories per gram of alcohol, which is only second to 8 calories per gram of fat
alcohol will sabotage your weight loss, because your liver will spend all it's time trying to process the alcohol before even looking at whatever else you've put into your body
you need to vary things to sustain weight loss both in your eating, and your exercise to shock your body out of plateaus - but this is wayyyy too detrimental to your overall health.
Ultimately it is your choice, i am just trying to help you make the right choice for your body's overall health. Your body is a machine AND your temple. It needs to be fuelled by the right things. You shouldn't starve yourself to loose weight, fad diets do not work and ultimately it is unsustainable and you will pile it all back on (and then some, did i mention fat cells have memory? That's why it's easier for us to put on weight after loosing it, and your body will CRAVE the fat like nothing on earth) and yes you might put on a little bit of weight increasing your calories, but once your body gets used to the changes, you will start to loose weight again, and sustain that weight loss. When i increased my calories from 1200 to 1400 i didn't even put on any weight, i just continued to loose weight.
Sorry if you feel this is a confrontational post. I really don't intend it to be that way. We are all here for advice and support
good luck gordz i hope you make the right decision.
