When you eat very low calorie, especially low carb - you can lose the sensation of hunger. This sounds like "good news," but it really isn't - eventually you may find your metabolism dropping and/or will experience fatigue and other unpleasant symptoms.
You really need more nutrition, and even on 1200 to 1500 calories it can be difficult to get in adequate nutrition (especially with gym workouts).
Here's a link to several food plans to give you some idea of what a more balanced plan might include:

this site (under dieting on a budget) also has a lot of resources, including information on exchange plans, recipes, and sample meal plans (the meal plans are for 1000 calories, so even those are "bare bones").
I chose exchange plans, not because you have to be on one - but the advantage to exchange plans is that they force at least some minimal balance.
For example, in your dinner there's no protein and nearly no carbohydrates - no fat either. Since those three are the sources of calories - your dinner is basically "nothing." A mandarin or tangerine is only about 30 calories, and only half of a fruit serving. It looks like yo're taking in fewer than 100 calories after noon. Especially if you're going to exercise in the evenings, you probably need to not only eat more, but also distribute your calories more evenly through the day.
