Weight loss and exercise

eat less, move more

you're welcome

One of the best places to start is by reading the "sticky posts" found at the top of the Getting Started forum. It will help you understand how to make the most out of MFP and how a calorie deficit works, etc. Start slow and get the hang of managing your food intake.

Best help I can give is-

get a digital food scale.

Once you have it, weigh all your food. Meat veg, snacks, packaged. All things.
Liquids, measuring cups and spoons. Oils and dressings are high calorie, so don’t forget them.

Now you have your scale, learn how to log. There is a learning curve, but once you have the correct entry for an item it stays with you- no more searching.

Double check your entries, as there are a lot that are incorrect. The USDA data base is good for single items, the package or mfg website for prepackaged items.

Have a reasonable deficit, 1lbs a week would be good, and eat food you like.
No need for diet food or labeling food good, bad, junk, healthy or unhealthy,
All food has a nutritional value, work in meeting your nutritional goals, MFP’s are fine, treat protein and fat as minimal.
You can do that eating pizza, just not too much pizza, ice cream, just make sure it fits in with your cals and nutrition.

You don’t need to eat different than the family, you will probably do best, to start with eating smaller portions of what you usually eat, then tweaking as you progress.

Cheers, h.

ETA: Exercise is great for your health. If you do exercise, remember MFP is designed to log and eat those exercise cals back.
If you move more you need the fuel to sustain that movement.
