I'm having some issues with my eating and starvation script. Any fixes?

Hello everyone, I am making a roblox game that includes an eating, and starvation feature. My eating script is causing an error, also, the console is not showing any errors so im 100% sure that my code is just buggy. I will include the starvation script and the eating script Whenever I eat some food, the next time it goes to remove a bit of hunger, it removes WAY too much

Eating script:

food = "Food"
hunger = "Hunger"
script.Parent.MouseButton1Click:Connect(function()
    for i, v in pairs(game.Players:GetPlayers())do
        if v:FindFirstChild("leaderstats")then
            if v.leaderstats[food].Value == 0 then print("error") else
            if v.leaderstats[hunger].Value == 20 then print("error")
        else if v.leaderstats[hunger].Value + 5 > 20 then v.leaderstats[hunger].Value = 20 
            v.leaderstats[food].Value = v.leaderstats[food].Value - 1 else
                v.leaderstats[hunger].Value = v.leaderstats[hunger].Value + 5
                v.leaderstats[food].Value = v.leaderstats[food].Value - 1
                    end
                end
            end
        end
    end
end)

starvation script:

hunger = "Hunger"
while true do
    wait(0.000000001)
    for i,v in pairs(game.Players:GetPlayers())do
        if v:FindFirstChild("leaderstats")then
            if v.leaderstats[hunger].Value == 0 then v.Character.Humanoid.Health = 80
                wait(2)
                v.leaderstats[hunger].Value = 0
                v.Character.Humanoid.Health = 60
                wait(2)
                v.leaderstats[hunger].Value = 0
                v.Character.Humanoid.Health = 40
                wait(2)
                v.leaderstats[hunger].Value = 0
                v.Character.Humanoid.Health = 20
                wait(2)
                v.leaderstats[hunger].Value = 20
                v.Character.Humanoid.Health = 0
            end
        end
    end
end
