I lost the first 45 pounds in 3 weeks by doing the following daily routine:
- 4 hours of swimming
- 1.5 hours of weights lifting
- 3 hours of swimming
- 2 hours of table tennis
1 BIG lunch, no other meal for the day, TONS of water.
Apps, books and all are completely overrated. Just be motivated and listen to your body, stop exercise when you reach your limit, rest, repeat..
The other 55+ pounds were lost over 2 years and a half without much exercise, just find the arrangement of fruits, lightweight cheese and vegetables + tuna that you love and eat it as often as possible.
