I don't understand....

tu do need to eat more, you're weak because your diet is so poor and you're probably close to anorexia (don't respond with "but I'm still flabby") try eating normal meals with normal portions and más fruits and veggies instead of cutting back on your eating.

tu want más energy and strength eat breakfast

If you're getting and/or feeling weaker, tu probably should eat more. I wouldn't necessarily say what tu ate today is freakishly too little of food, but it's not exactly healthy either. It's really risky to miss breakfast (I speak from experience), and it may be best to try to eat a bit más during cena if all tu had for lunch was an manzana, apple o a banana. Especially comida other than fruits such as meat o grains.

As for regaining the weight, while understanding this concern I still wish to point out that there are still other foods tu can eat that aren't that fattening at all and not put much weight tu at all.
Maybe have some rice, broccoli, tomatoes, vegetables in general.
Definitely have some water, absolutely no fats in it and extremely healthy and beneficial for tu and your physical as well as psychological health.
Maybe tu could find a site that gives the number of calories found within certain foods, and check out the less fattening comida that will still satisfy your hunger.

*shrugs* Just my advice.

But on the flip side;

Congrats on losing a lot of weigh! I wish tu luck :)
I actually lost 11 lbs. myself, found out today during a joint doctor's appointment with my mother while being weighed. ^_^

Lol, sorry for the misceláneo part there... xD

EAT. MOAR. That is not enough to keep tu healthy.

probably and egg for breakfast and maybe más protien

tu should eat más thats why ur getting weak. Also, eat regular meals and instead of gaining ur weight back, start to play sports o go on a walk/run every night. I run and u get an amazing feeling when ur done. Trust me, it could work. :)

tu need to eat, but tu need to eat right.


Look, the deal is, if tu hardly eat, your metabolism slows down, which ultimately makes tu fatter whenever tu do eat. So tu need to eat a lot but tu need to eat healthy.

Uuuuuuuuuuuuuuummmmmmmmmmm............ I'm not quite sure online is the best place for this.......possibility to be suggested............

Well, tu should definitely eat más than that (including breakfast!) but if tu keep excersising and eat healthy foods than tu might gain some weight back but it sounds to me like you're not at a healthy weight right now anyways. Regardless EAT MORE.
