Hello,
I too had to increase my fat intake so as to optimize the weightloss with Alli, and also to ensure I had enough fat in my diet to get the proper liposoluble nutrients from food (although I do take a multi before going to bed, as advised... but nutrients from food are still the most beneficial kind).
One thing I realized while logging my food is that although my diet had the proper proportion of calories from fat, there were days where I ate too much saturated fat and not enough of the good fat, i.e. the mono and polyunsaturated fats. Hence, too much artery clogging, and not enough of the fat that will increase my HDL (good cholesterol) and ensure that my arteries remain flexible. So now, I make sure to also respect the recommended proportions for each fat (basically a third of my daily fat allowance is given to each of the three kinds of fat). For those who wonder how to calculate that, logging your food intake on www.fitday.com will do it for you.
For those who are perplexed about eating more fat to lose fat, you need to remember the following: 1) Alli on prevents a portion of the calories coming from fat from being metabolized, not all kinds of calories. And in the end, it becomes a low-fat diet. 2) Any kind of calories will make a person gain weight if too many of them are eaten. If one eats 3,000 calories of veggies, they will most likely gain as much weight as someone eating 3,000 calories of either fat or protein. Fat is not just created by eating fat! 3) Like Betty said, not eating enough fat means eating more protein... but, more importantly, more carbs. As you may already know, an excess of simple carbs will trigger the oversecretion of insulin, which promotes fat storage, sugar cravings (thus more fat stored... vicious circle) and fatigue ( as well as higher triglycerides... not healthy!). 4) Fat calories are more filling and help respecting daily calorie allowance by being less starved.
Hence, when they say to eat a balanced diet, it's for our own good!
