I kind of follow SW. I say kind of, I follow their ethos of fruit and veg every meal, keep the treats to a bare minimum, exercise and weekly weigh ins - Ive lost two stone since May.
I dont follow the eat as much as you like of certain foods, because they are my triggers and Ill eat them till I would explode - bread and pasta - they are now limited because for me they sugar spike me and Im hungry again soon after eating them. But other then upping the protein and adding veg - lots of veg, meals are the same as Ive always made. Ive upped my movement, 15k steps a day is my norm, I might throw in some skipping or body toning, but thats rare tbh, Im busy and down time Id rather be online. Today so far Ive done a 5 mile nature hike and a two mile cycle. Food eaten, bacon roll with lettuce and tomatoes at 7am before the hike, after the hike, yoghurt, muesli and prunes and a slice of banana bread ( laid on at a hotel ) and that will do me now till this evening when I shall eat fish and vegetable with couscous in a harissa style sauce
For me its about the small sustainable changes that I make now subconsciously , I automatically choose the lower fat, lower sugar, lower calorie dense food. And I love my air fryer - fat free chips which are actually tasty - yummy :)
Sure I go mad and pop in to McD's or the chippy, who doesn't , but thats just one meal, next meal is back on plan - the healthy eating plan for life, not dieting , losing for it to come back again
