A new study reveals that even though we are exercising and eating at the same levels as 30 years ago, we are not able to sustain our weights like before, leading to obesity and other disorders. The reasons for this phenomenon:

1. More exposure to chemicals(packaged foods, pesticides) leading to hormonal changes.
2. Prescription drugs which have exotic side-effects.
3. Processed foods, especially those with artificial sweeteners, which are mutating our microbiome (gut bacteria).
