Interesting situation! Do we need this....

I did low carb for about 4 years. I was serious about it - extremely low carb. And it worked in certain ways. I had a very good ability to go for long periods without eating anything while doing moderately vigorous work.  I was great at dealing with cold weather, but struggled with heat stress in the summer. That kind of diet automatically means high fat, and any success for me on that diet meant being extremely picky about what kinds of fats I ate. When I started to get cheap on that diet, going for chicken and pork and other sources of fat high in polyunsaturates it became a problem. I'm thinking now the key is not total carbs or fat,  but total polyunsaturated intake. I experimented with an ultra low fat diet partly because I realized that even the best sources of fat are considerably higher in polys than something like a banana or a boiled potato. So I cut the fats to see what would happen, and so far it's been great. I'm coming up on 2 years now. No cravings for anything with higher amounts of fat have materialized at all. They say the polys are essential fats, suggesting that if you don't eat them you'll die or get gravely ill. The evidence is uncertain that they're needed at all. They seem to be fattening and accumulate in our bodies with age. As body fat levels go up, the percentage of polyunsaturates in the adipose tissue also goes up. The only way that can happen is if you are eating them. Our bodies don't make them. If we do need them, I see zero evidence that they are needed beyond about 0.5% of calories, and pretty much anything natural that you can eat has at least that much.

When I was doing low carbohydrate I did not do a very high fat version of it. Essentially, I replaced A lot of the complex carbohydrates with fiber and a bit more protein. Fat went up but not a huge amount.

I often find it hard to find the time for a healthy ride so my "thing" now is a modified version of HIIT. A couple minutes flat out on the rowing machine several times a day. Consider it 10 minutes a day of a whole body flat out sprint.

I'm a great believer in High Intensity Interval Training too. I know people who spend hours in the gym, and they seem to like it, but I prefer to settle down to listen to music and watch films etc.

Just 5 minutes on the exercise bike to get my heart and lungs pumping faster here and there when I feel like it keeps me going.

It's a pity more people don't know about HIIT.

@cd318 everything I read about HIIT indicates it is every bit as good for general health as the 3 times, 30 minutes vigorous per week (which seems to be creeping up), if not better. I really like the rowing machine. I am often surprised at the muscles that can be sore after 1 minute.

@rbertalotto Your story is amazing and I've had similar experiences with low cost gear.  It always amazes me when reviewers focus on how expensive the gear they're reviewing costs. You would think a reviewer would gain more attention by finding the 'diamonds in the rough'.  I'm sure there are others, but I enjoy watching Steve Guttenberg (The Audiophiliac) and Steve Huff on their YouTube channels for reviewing a variety of gear based on SQ and not price.
