Any suggestions on how to do it?
Pros and cons?
--------------
I'm in a rut. Unhealthy foods, low energy, overall not feeling well, gained weight.
Every time I try to start nutrition plan I fail. I feel like I need to detox my body before I can start on a plan. My googling basically produces adds for Isagenix, which is MLM company. However, I know someone who's done great with their cleanses.
What else is out there?
I'm looking for a boost to get me over the a huge hump.
I'm not sure if this will help you, but I've had success following some general principles. I was doing a (poor) vegetarian / vegan diet for ~6 years and ended up with some nutritional deficiencies and excess weight which I have now corrected.
The following probably won't work for everyone (and so might not work for you!), and given the sheer amount of dietary resources out there which contradict one another on even basic principles I think the only thing you can really do is try out various approaches for yourself to see what works. It baffles me to no end how we talk of artificial intelligence and sending a guy to Mars, yet we still haven't figured out what we should be eating. :)

Macro-nutrients: Majority of calories comes from fat and protein. I don't avoid carbs entirely, but the fat and protein is normally enough for me to reach satiety. Fruit and starchy veg are OK in moderation (typically these are slower burning carbs and so are more gentle on your blood sugar levels), but I avoid things like fruit juices and sugary snacks.
Foods to Avoid: Sources of gluten (including "healthy whole grains"), vegetable oils, refined sugar, beans & legumes (unless thoroughly prepared), dairy in excess.
Awesome Foods: Organ meats, oily fish, shellfish (mussels/oysters), eggs, fatty plant foods (avocado, olive oil, coconut, coconut oil), bone broths, dark chocolate, nuts (not peanuts!!!), as much non-starchy veg / plant matter as you can eat.
Supplements: Personally I supplement for Iodine and Magnesium. Whatever you do, I'm pretty sure your supplement profile should avoid: Multi-vitamins, vitamin-A, calcium.
