You don’t need to do higher doses than you need though op. If it works for you at 5 or 7.5 then stay there. Don’t move up for the sake of it, stay on whatever dose for as long as it works.
but do think you’re not even half way there yet, the reason your successfully dieting is as the drugs enable this, your blood sugar and insulin is managed,meaning no cravings, your fat is available for burning, meaning to energy slump or hunger, what this means is we can eat in a calorie deficit and lose weight successfully, without sitting thinking about the crisps or chocolate or eating larger portions than we need. Without the drugs or too low a dose and that’s very difficult, and impossible for most of us.
do also think of this as long term, the rest of your life. Because getting to target is just the first step in a long journey, you also need to during that journey consider muscle and eat enough protein and work out, strength train, this is key, as otherwise it’s muscle you’re losing not just fat. And you won’t like what you see in the mirror when you hit target.
once you hit goal you need to focus on building muscle, as it is difficult to do in a deficit, during weight loss you’re focused on maintaining muscle and fat loss, and then when your happy with your body, you need to focus on maintaining, maintaining your body fat percentage, your weight and your muscle mass. For ever.
right now you’re on the first step of your journey, weight loss,
I’ve seen a lot of people on line who think wow I’m successfully dieting, go me, the weight is coming off, I don’t need the drugs, not understanding it’s the drugs that is enabling that, it’s the whole point of them, and then coming off and either regaining immediately or struggling as the hunger returns, the cravings return, and their bodies return to what they were pre drugs, because no drug works when you don’t take it.
good luck x
