I decided recently I need to increase calories by about 1000 per day to reach my targets. At first I added 2 Litres of fruit juice which gave me the full 1000, BUT also allot of gas!!! (I dont eat friut very often). So now Im down to 1 Litre, and that only gives me half the calories! At 34pence per litre, its a very inexpensive and healthy way, but what could I add thats inexpensive and healthy (and very quick to consume/prepare) for another 500???
