this is the log

my health was 45% when the script was running, so it is not recognising my health is < 99

It only works in combat, the value is cached. If no value has been cached yet, it should return 100. Use skills#getDynamic & skills#getStatic to compute your own health percent.

didnt know, thanks for that! I changed to use static and dynamic, works like a treat, might not be the cleanest but works:

 

private int getHpPercent() {
    int staticHp = getSkills().getStatic(Skill.HITPOINTS);
    int dynamicHp = getSkills().getDynamic(Skill.HITPOINTS);
    int hpPercent = 100 * (dynamicHp / staticHp);
    return hpPercent;
}

public void eat() throws InterruptedException {
    int hpThreshold = 100;
    log("Checking Health");
    if (getHpPercent() < hpThreshold){
        log("Health is not 100%");
        if (getInventory().contains("Shark")){
            log("Eating Shark");
            getInventory().interact("Eat", "Shark");
            new ConditionalSleep(1000, 100) {
                @Override
                public boolean condition() throws InterruptedException {
                    return (myPlayer().getHealthPercent() == 100);
                }
            }.sleep();
        } else {
            if (getInventory().contains("Varrock teleport")){
                log("Teleporting to Varrock");
                getInventory().interact("Break", "Varrock teleport");
                new ConditionalSleep(1000, 100) {
                    @Override
                    public boolean condition() throws InterruptedException {
                        return (!getCombat().isFighting());

Make sure you cast to float/double when doing the division, your method should return only 0 or 100 if I'm not wrong

Couldn't you just say 

if (myPlayer().getHealthPercent() < 50 && getInventory().contains("Shark")) { Health % below 50 & Inventory contains sharks
        log("I got an owie, let's eat!");
        getInventory().interact("Eat", "Shark"); Eats a shark
    }
}
