Hi guys, I have a question and would love people's opinions. I'm a 23 year old male. Back in summer 2014, I was a whopping 17 stone. I lived an unhealthy lifestyle which consisted of no exercise and plenty of walks to the takeaway. I decided to totally change my life around and get fit and loose some weight. I started boxing 3 days a week and I was in the gym 2 days a week doing cardio workouts as well as weight training. I was always training hard. The weight was falling off very quickly, and I was eating around 3,000 to 3,500 cals of quality food a day. I never consciously starved myself and ate to my hunger cues. (Physical sensation in my stomach) Out of nowehere I started to feel fatigued, but I carried on training hard despite the fatigue. But then the rest of the symptoms of CFS care. My entire body was affected. Muscles, joints, congnitive, heart and cardiovascular. Despite feeling all these symptoms, I carried on exercising vigorously although I was slowly declining becoming more unfit by the day. So I'm just wondering, could the problem of been I wasn't eating enough? Even though I didn't feel hungry? And obviously carrying on pushing myself when my body was really tired. Thanks.
