Eat Clean? Paleo? Gluten Free? Everything in moderation?
CrossFit? Run? MMA? Yoga?
The Internet is incredible because there is so much information out there. With that much info, inevitably you're going to run into ones that say X is good for you and others that say X is bad for you. There are arguments for all sides - things you should/shouldn't eat, exercises you should/shouldn't do -- there's no one right answer.
Just like years ago I had to make peace with the fact that my size 0 best friends could eat burgers and fries and not exercise and still not gain weight -- and I couldn't, I have made peace with the fact that not all food and fitness suggestions will work for me.
When people ask me how I managed to lose weight (mainly due to weight lifting/CrossFit plus doing the Whole Life Challenge - no dairy, no sugar, no preservatives etc.), they react in horror thinking that it's all too extreme.
I have a friend who eats clean (includes dairy and legumes) and only walks, but walks regularly and vigorously, and she manages to lose weight and keep it off.
Another friend of mine follows a Paleo lifestyle (no legumes, no sugar, no dairy) and runs (no weights). She is also very healthy and is able to maintain her weight loss.
Yet one more friend eats whatever she wants in moderation and does general aerobics exercise and still manages to lose weight.
We're all different. We have chosen to follow an eating method that suits our bodies and to do exercises that suit our interest levels as well as have a positive impact on our body.
Following the Whole Life Challenge guidelines work best for me -- however, even though legumes are allowed, I found that legumes don't suit me well at all -- therefore, I have practically eliminated them from my diet. I found that dairy doesn't bother me, so I am ok with having a bit of milk, some Greek yogurt, and even some cheese (not Paleo or WLC friendly, but alright under 'eating clean' guidelines).
As much as I would love to run, it just hurts my knees too much. However, intense weight lifting and MMA suit me just fine.
I find it amusing that more people react negatively to CrossFit than they do when I mention MMA training - I would think that being punched in the face would be more alarming on the injury scale than doing heavy squats -- but everyone has their own opinion and their own preference …
In the end - one size does not fit all.
You have to figure out what works best for you. What decisions are you going to make for your health and fitness that will allow you to comfortably include them in your lifestyle as an actual lifestyle (vs a diet or a phase)? What will you enjoy doing so that the tasks don't feel like a bore or a chore?
These decisions are all up to you.
The articles out there are often interesting and informative, but I would strongly caution about following something blindly and expecting the results to work with universal success. Build your knowledge base. Be patient through the trial period. Find out what works for you -- and don't judge others for what they have chosen to do.
