If you're having trouble reaching 1300-1400 cals, you've likely adapted to a lower calorie intake (metabolism has slowed). If you start eating more, after awhile your metabolism will fire back up and you'll be hungrier and able to eat more. I find, the more you eat... the hungrier you'll feel (once your body adapts). The same goes for eating too little... your body eventually adapts to that intake and you no longer experience hunger on a low intake of calories.
So it's just a matter of increasing your calories slowly and your body will adapt.
Male professional athletes and body builders may eat around 5000 cals. The average person, especially a woman does not require that many calories. I workout at high intensity 5-6 days a week (for 60-90 mins) and weight train and am active outside of exercise and I eat around 2000 cals to maintain my weight (around 1600-1700 cals to lose).
Your body goes into starvation mode after a prolonged extreme calorie deficit. As long as you are not losing weight too quickly, more than a rate of approximately 1-2% of your total body weight per week, it isn't something you should have to worry about.
Do you currently do cardio and strength training? I don't think a beginner to exercise should jump straight into high impact aerobics but a novice/intermediate level exerciser should be able to handle the program. If you already exercise, you shouldn't have to increase your calories by much. If you don't currently exercise, then yes... you may have to increase your calories a bit. Just add an extra 100 cals to each day for a week and then another 100 cals the following week until you reach your target.
You don't need supplements for a cardio program. In fact, you don't need supplements for a weight training program (which btw, Insanity will not provide you the same benefits of building muscle as an actual weight training program, it is an endurance program).
As long as you are getting what you need to supplement your Vegan diet then additional supplements for a cardio program are completely unnecessary.
According to Spark, you'll probably burn around 300-500 cals for an hour of Insanity (it's listed under "Aerobics: High Impact), depending on your personal information (age, weight, etc.) which is a typical amount of calories to burn during any high intensity cardio activity. You're not going to burn some impressive amount of calories like a that of a professional athlete. When it comes to cardio, you can only work as hard as your current fitness level will allow you. If you are not used to working in your maximum heart rate and sustaining it for prolonged periods of time, you will not burn as many calories as the claims from programs like this. Invest in a heart rate monitor for a better idea of how many calories you burn.

Take your focus off the Marshmallow. www.leangains.com/2010/01/marshmallo
"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. It doesn't happen, what does happen is you get results. Lifting Barbie weights does nothing but waste time.
