Did you know that only 3% of North Americans can consistently do the following tasks:
1. Refrain from smoking tobacco?
2. Eat five servings of fruits/vegetables daily?
3. Exercise five times a week for 30 minutes?
4. Maintain a healthy body-weight?
That doesn't even include things like getting enough sleep, eating enough protein or having a healthy mindset, to name a few other things that make up a healthy (and sustainably so) lifestyle.
Can you do those things consistently?
If so, and you're still not seeing the results that you want, you can consider trying more advanced strategies.
If not, you really have no business trying any other strategies like supplements, skipping meals, intermittent fasting or anything else that promises quick results.
It's not super sexy, and it doesn't happen fast, but if you have a history of yo-yo dieting, you know that those things are not sustainable.
It's much better to progress slowly, adding one new skill at a time, so that you can make real and lasting change.
There is absolutely no need whatsoever for most people to use man-made products to lose weight!
Get the basics down first. Ask for help if you need it.
