Let me show you some pictures of some of my main meals while on my self-invented (but strictly calorie-controlled) diet. Some of them are more calorie-rich than others, but none exceed 737 kcal, and the lowest pumps only 376 kcal into me.
Here's the 737 kcal meal:
That's four rashers of best back bacon, some fusili pasta with basil pesto, spinach, and a blob of tomato ketchup. The pesto was the spoiler, contributing 150 kcal all by itself. A very quick, tasty meal though.
The next highest in calories was this slow-cooked casserole featuring stewing steak, sweet potato, onions, mushrooms and green beans. This bloated me out till I went pop, very satisfying, and yet it was only 637 kcal:
Next up is this lunchtime salad (yes, a salad) at 607 kcal, based around a 180g tin of red salmon. The spoilers here were the blob of mayonnaise, which added 144 kcal, and (surprisingly) the apple, which added 136 kcal:
Now it begins to get a little saner. This meal, with two sea bass fillets, potato, green beans with french dressing, and a blob of tomato ketchup, was only 581 kcals:
Dropping rapidly down into the guilt-free zone, this next meal of chicken breast, potato, baked mushroom, asparagus with french dressing, plus the usual blob of tomato ketchup was only 504 kcal:
At 493 kcal here's amother chicken meal with potato, carrots and sugar snap peas, this time in gravy:
And finally, slimmer's Nirvana with one fillet of hake, potato and broccoli, and (guess what) that good old blob of tomato ketchup. Only 376 kcal:
The secret there was to have only one fillet of fish, not two. Pity I mangled the hake when getting it onto the plate!
I suppose what I'm trying to demonstrate is that your main daily meal can be attractive and hearty and nutritious, and yet still not blow the diet. I think you're wasting your money if you buy shop-bought slimmer's meals, exercise machines, and weightwatching club membership. Just eat main meals like this, substantially cooked using fresh ingredients.
Plan your daily calorie intake around your main meal. Make sure you eat something for breakfast and lunch, late afternoon if you really need to, and late at night if you really need to, bearing in mind that once asleep you're inactive and not burning up any calories to speak of. Regular food intake, however token, staves off hunger and avoids bingeing. Drink tea or black coffee or water at regular intervals. Keep away from sugary snacks and drinks, and also chocolate - a tremendously difficult thing to do if you're hooked on these things, I know.
Anyway, I thought you'd like to see what my diet-meals are really like, and why I think I can keep my diet up for as long as I want!
