Smont gave a good reply above about the basics of calories in, calories out.
There is no one best diet because different diets work differently for different people.
Like for me, what works best is 4 to 6 small meals a day with a serving of protein at each meal and then I adjust carbs based on my particular goal at the time. But that may not work best for you - you may respond best to fasting or eating within a certain time frame. I know I don't just from experience trying it.
For supplements, there are a lot of great options. Normally I go into a lot of great detail on this, but sometimes I think my posts go into more detail than people want sometimes.
Here's a list of what I would do, and how I choose fat burners:
- Lean Edge - if I was picking just 1 fat loss product, it would be Lean Edge
- Thermagize XT or Lipo Elite - would be what I would add if I wanted to add a stimulant based fat burner.
- Thermo Scorch or LipoVantage - would be what I added if I wanted to add a MitoBurn based fat burner.
- Reduce XT - is what I would add for cortisol control. Many people also notice improved mood with it.
For people that consider themselves skinny fat, the term skinny fat often refers to people that have a lot of visceral fat.
Ab-Solved is perfect for people that have a lot of visceral fat, as it is a localized formula that is designed to help target visceral fat. Keep in mind, this isn't some infomercial type topical fat burner that promises results but is really just pulling water out. It's a scientifically designed formula that delivers the active ingredients directly to the target areas, which gives you the chance to target burning them.
