I don't understand why myfitnesspal doesn't use the weight data in the withing's health mate app, as I have linked the two.
Anyway, I have started with my new diet, and is eating fat free and sugarfree yogurt (I don't know what it's called in English but in Scandinavia we call it Skyr) mixed with banana, raisins and almonds in the morning. And then dark bread with no butter for lunch. I were told I shouldn't drink milk and I should not eat pasta. Which is weird as the personal trainer I had some years ago told me to eat pasta instead of rice and potatoes.
Bread for lunch? That's it? What about dinner?
I'd suggest you use one of the calculators out there - there are ones of varying complexity at myfitnesspal.com, iifym.com, 1percentedge.com/ifcalc, etc. Plug in your height/weight/age and it will tell you how many calories you should eat to meet a variety of goals and the amounts of nutrients to stay healthy.
You don't need a crazy diet to lose weight, just a calorie deficit. I eat about 1750 calories per day currently and generally eat something like the following:
Breakfast - a high protein french toast or eggs with turkey bacon
Lunch - a variety of quick meals like canned chicken or tuna with rice or leftover dinner + vegetables
Dinner - chicken tex-mex wrap/turkey chili/meatloaf/fish/variety of chicken recipes + vegetables
Snacks - usually two of protein shake/quest bar/peanut butter/chips and salsa/hummus/nuts
Just find foods that have a decent protein count and aren't high in sugar and fit them into your macros. Oh, and don't be afraid of fat - you need it, although you'll be sticking to the unsaturated variety.
