Go out and eat at a restaurant. Mexican food in particular (beans, rice, chicken and vegetables) has a great macro-nutrient profile (high protein, moderate carbs) if you avoid the cheese and fried items.
What’s the easiest way to get your pH level up so you’re more alkaline than acidic? Drink at least one (ideally two) fresh green juices every day. Buy a Nutribullet and throw in a handful of spinach, a handful of kale, half a cucumber, an Apple, a squeeze of fresh lemon juice and a cup of water. Blend it up and drink it. Simple.
To keep sane and stop your metabolism from slowing down, you should also have one day per week where you eat whatever you want. This is called an “off day”. If you’ve been craving chocolate, fries, etc, you eat them on your off day. Keep in mind, however, that you shouldn’t eat 20,000 calories during your off day. Eat what you want, but don’t over do it.
