I'm not the expert, but most people make dieting too complicated
it should be a life style change and keep it simple. Avoid, mayo, large amounts of salt, no sodas, processed foods, and too much cheese. Eat a plant based diet and now is the time to enjoy it with all the fresh, garden produce available. Eat everything fresh, fish, chicken, pork tenderloin, very Little beef and keep your portions to 4 ounces or less. Lots of fresh green veggies. Make soups with no fat, except olive oil, add lots of fresh herbs, spices, and veggies. Cabbage is a good filler and very tasty. So good and you can have it in the fridge at all times. Go for lots of walks, take your dog along if you have one. Go with a friend , too. Park at the far end of the grocery store lot, a great way to get in those extra steps.
I lost a lot of weight years ago doing just this, and my secret was - I told no one. I did not want folks asking me everyday how I was doing. After about 22 lbs, they began to notice.....I simply told people I made a lifestyle change by walking and eating healthy foods. Nothing more was said. When they ask how much weight you have lost, say "enough for right now". Someone told me this to avoid those who say, "well, how much more do you want to lose, or you look sick".
I also stayed away from all types of chips....eat cucumbers and carrots slices instead. It fills you up and keeps you healthy.Do it for you!
