I recommend you always remember that consistency is what really matters.
If you can work out at least 3 times a week, that's better than doing absolutely nothing.
Also, unless you're trying to compete, it's ok if you fall off the consistency. Just remember to get back in it.
Absolutely this. Consistency is king (or queen) and over doing it and then quiting is a big newbie mistake. The other point is if you want to lose weight then it's calories in calories out, you must make sure you're burning more than you're eating (just don't starve yourself). Eat a healthy "diet" you can stick to that you like as your resolve WILL falter and fail and if your food isn't one of the struggles then you're more likely to keep on it.
