Bootcamp is the way to go. Good job on making that decision. Now your next task is to stick to it. One month won't be enough for you to achieve your goals though, but that's for you to decide after that one month ends.

If you're hungry you can just drink some milk or eat some wholemeal bread or some chicken/tuna sandwich, or maybe some eggs, or oats. Losing weight does not equal starving yourself, that's a wrong perception that the public has unfortunately cultivated over the years.

General rule when working out, increase protein intake to enhance muscle recovery and muscle building. Applies the same even if your goal is to lose fat. Also from what I gather in LYN forums, more muscles = passively burn more fats, so that's something pleasing to hear at least. If you're worried about being muscular and all, don't, because its not easy at all to look muscular even if you try, especially for the average female.

And stop smoking if possible... Its counter-productive to life in general.

Excellent! That's proof that you're really developing a healthier lifestyle and your mentality is changing for the better. Hopefully, soon enough you'll get totally disgusted by it and will want to avoid it at all costs... Just like what happened to me and junk food.

Hmm tuna can guaaa... A lot of members in LYN eat tuna in between meals. As for Milo, personally I avoid drinking Milo because it doesn't feel like I'm consuming 'real' nutrition. It feels empty but I can't explain why... Hopefully another member can help here. I only drink it as a last resort when I run out of milk. Btw avoid adding condensed milk into your Milo, or any of your drinks for that matter.
