You can understand my point above was more so reflecting that a watch alone won't help you lose weight, as you say, you actually need to do the work regardless of whether its too hot, too cold or too rainy.

When we say "this point in the obesity epidemics", something occurring in our society so fast that it is now an epidemic makes me think it's more environmental that internal. However, I do think there is a chunk of evidence coming out in support of other metabolic measures being at play during weight loss, but we have to be careful simply assuming we fall into this category because its too hard or we're not seeing results.

There is an overwhelming abundance of convenient food around us which is super high in calories. I have friends who have travelled to the US and they could not believe how big portion sizes were, the types of foods being serviced and (supposedly) how hard it was to find quality vegetables with food.

It's excellent that you were able to improve your health so much through just upping your step count.

There are other factors too: * What were the types of foods you were eating? * Did you increase your calorie intake proportionally to the additional steps? It doesn't take much

Our bodies HATE losing weight (fat) and they make it difficult for us.
